Problems with 2007 Mazda CX-7 ENGINE

On average, the 2007 Mazda CX-7 starts to “feel” problems with the ENGINE and its various aspects after 95 596 miles.

Recently reported ENGINE problems on 2007 Mazda CX-7

Tl* the contact owns a 2007 mazda cx-7. the contact stated that the vehicle would continuously exhibit a ticking noise from the engine compartment. the vehicle was taken to an independent mechanic, who stated that the noise was normal but they were unable to determine what was causing the noise. the manufacturer was made aware of the failure. the vehicle was not repaired. the failure mileage was 49,000 and the current mileage was 49,500.

Tl- the contact owns a 2007 mazda cx-7. the contact stated that while driving at various speeds, the vehicle started to make a whinnying noise before the check engine lamp illuminated. the contact mentioned that white smoke started to emitted from the exhaust. the vehicle was taken to the dealer. the technician diagnosed that the turbo charger was defective and needed to be replaced. the manufacturer was made aware of the failure. the vehicle was not repaired. the failure and current mileage was 62,839. pm

Timing chain replacement resulted in a catastrophic failure of the high pressure fuel pump and its housing. replacing the timing chain returned the engine to production line specs, that were too much for a worn fuel pump to handle. the increased pressure to the fuel pump shattered it into numerous pieces less than 100 miles after the timing chain was replaced. said pieces became lodged inside the cam shaft and ended up bending all of the valves. the necessitated a complete valve job, removing and replacing the cylinder head, fuel pump, cam shaft and oil control calve. at worst, all timing chain replacements should require a fuel pump change in order to prevent the sequence of events that happened to my car and thousands of others. *js

December 2012 (at about 64,000 miles) dealer replaced timing chain under extended warranty but didn't do anything to correct intermittent power loss and engine hesitation that i had complained to them at the time. november 2013 (at about 78,000 miles), the car experienced severe loss of power, stalling and heavy white smoke from the tailpipe. dealer claimed "oil sludge" caused engine and turbo failure and refused to bear any responsibility or cost to fix. mazda usa also refused, claiming the problems were due to insufficient oil change by the customer. since we change oil regularly, we don't buy mazda's claims, especially when they just opened up the engine less than a year ago to change the timing chain, and at that time didn't claim there was any "sludge" inside. seeing many similar customer complaints on the internet, it seems mazda has been trying to hide a serioius design and/or manufacturing flaw by blaming the customers as the cause of it. ?*tr

Driving on the highway, turned on the a/c and a burning smell started emitting into the car. open up the windows and the odor was coming from the engine. very afraid to drive car and after reading numerous reports of similar incidents here: http://www.arfc.org/complaints/2007/mazda/cx-7/engine/problem.aspx i'm afraid my car is suffering from the same deal. *tr

Timing chain replaced on 2007 mazda cx7, july 2013. vehicle over extended warranty issued by mazda, repair was out of pocket, even though this is very common problem with this year mazda. now 5 months later, second timing chain has gone bad and mazda is refusing to accept responsibility stating that the new timing chain failure was due to low oil in vehicle. i have service receipts to prove that all oil changes had been done, and that this was not the cause of the second timing chain failing, but more of continuance of faulty, defective mazda parts. this is a huge problem with this company with an outstanding number of consumer complaints. they do not want to accept any responsibility for their own problem, instead putting it all back on the consumer. please, get involved and put a stop to this before these defective parts cause someone to lose their life!!!! *tr

A friend of ours was driving to pick us up from the airport (our car hadn't been started for a couple of weeks) and, about 15 miles into the trip, the ac quit working. when he got to the airport, the car engine was smoking, there was a burning smell coming from the engine, and it sounded like a bearing was out of whack. we drove it home (approximately 45 miles), and the noise got louder and the engine started rattling louder and louder the closer we got to home. we took it to a mazda dealership this morning, and they informed us that the ac compressor had seized and it, along with the belt (in addition to any other parts that may have been damaged) needed to be completely replaced and the refrigerant flushed/refilled. i did research and found out that this is a very common, known issue in 2007 mazda cx-7's with low mileage. *tr

I purchased a used 2007 mazda cx 7 august 2012 with 60k miles. recently took car for oil change at the dealership recommend to needing timing chain replacement, replacement of engine coolant and oil leaking around the engine. the engine is makes a loud tapping sound like the engine rod is going out. *tr

Tl* the contact owns a 2007 mazda cx7. the contact stated that while driving 60 mph, the vehicle stalled without warning while all of the instrument panel lights illuminated. the vehicle was towed to an independent mechanic for diagnosis where it was advised to the contact that the engine needed to be replaced. the vehicle was not repaired. the manufacturer was not notified. the vin was not available. the approximate failure mileage was 82,000. *tr

A/c compressor locked up. *tr

While driving on the highway i heard a ticking noise after a few seconds later the car lost power and smoke came out of the exhaust. when i pulled over i took the cover off from the engine and noticed that there was oil coming out from where the top of the oil goes.the oil pressure on the block was compromised due to failure of the turbo. when taken to the roger beasley mazda dealership and the car was cranked the dip stick shot out from the engine. the dealership indicated that there was carbon build up but could not explain why. the car was towed to another acs certified mechanic and confirmed that the engine failure was due to the failure of the turbo. before taking the trip on 4-18-2013 i took my car the mazda of mesquite dealership because i heard a ticking noise and the technician indicated that the noise was normal. also the technician performed msp 36 reflashed pcm with updated software and cleared all fault codes since there was a recall. three weeks later the engine goes out. the manufacture warranty expired, but have a in service warranty. the in service warranty agency denied the claim indicating that it was not normal wear and tear of the engine failure. i contacted the dealership and also emailed the manufacture to express my concern and both agencies directed me back to the in service warranty. both the dealership and in service warranty are not willing to assist in the cost being that the cx7 model is a lemon in my opinion. there have been many claims against this model by other consumers in which was confirmed by the employees at the georgetown roger beasley mazda dealership. the employees indicated that the cx7 model has a lot of problems that is why the cx5 replaced the cx7 model. since the claim was denied i have spent over 1000 which does not include any repairs, on a side note i was 300 miles away from home. *tr

As i was driving, the timing chain broke and imploded into the engine, damaging the engine which now needs replacement. this appears to be a common occurrence with this vehicle. *tr

Turning into a walmart parking lot my car shut down for no reason. almost got hit by another car that was passing by since i was not able to turn. turning into my apartment complex the car turned off again. started to research issues with this car and i ran into many similar complaints. car turned off another 4 times. car shakes when i turn ac on.and when i place it on reverse. also had the clicking noise but it seemed to go away. there seems to be some sensor issues. i took my cx7 to mazda so that they can see what is going on. they ran tests. came back and said it would cost me about $3500. it was a list of things that could be wrong they said, they were not so sure what to say. mechanic then stated that since he works at mazda he probably should not be telling me this but he said that he has seen that problem one too many times with this particular car. that yes mazda does know about it but they blame the owners. so i asked it i were to pay this would i get some warranty, he said no because the same problem will happen again. god forbid that my car turns off and i have and accident, since car gives no warning. i have 2 children that ride with me all the time. mazda had some sort of recall on this car a few years ago. i purchased this car february of 2012. i know understand why this person took car to trade out. maybe they got notice but did not care to take care of it, they traded the car in. i think they should look at those issues on all mazda cx7. their main issues are the turbo, the ac, and the timing belt. if you read other complaints you will see that its the same issue which is due to the actual car not the owners, please help us affected by these vehicles get mazda to finally take responsibility for this. make them recall these cars and get the problem fixed. to where we wont run into the same issues over and over again before someone looses a life. *tr

65mph car dropped out of 6th and powered down. turbo killed the engine. *tr

The engine light came on (not the first time). the mazda mechanic said it was the ect sensor. it was replaced and the engine light came on again the next day. took it back and they said, well it is probably another problem. i have taken t back a few time, but no one is able to give an actual solution. i took it to a non-affiliated mazda mechanic and he said it is the throttle (the car stopped again in may, 2015) and hears the engine noise which could be the timing chain. i just don't trust mazda or it's mechanics and

My check engine light came on as i was driving at 40 miles per hour. i did not notice a difference in the way the car was handling, however i took my car into my local mazda dealer to have it checked. they informed me the cars timing belt needed to be replaced and there was sludge on the engine. ironically i had just had my oil changed and my engine cleaned of sludge less than 2 weeks prior. we submitted the claim through my extended warranty and after a week got it approved. the morning i was slated to pick up the car i was told by the dealer that there was still an issue that they needed the car later. a few days later they told me i needed my engine replaced. the extended warranty denied the original claim now and the claim for a new engine due to poor upkeep, though i have my records of maintenance. i have only had the car for 1 and 1/2 years. this is ridiculous. i am now in the process of taking the car to another mechanic, bear in mind i have been without transportation for about a month and am pregnant. after researching this issue i have discovered tons of issues with the 2007 cx7 which can result in severe safety issues, engines losing power etc. mazda is not owning up to any of it. no engine should die at 76,000 miles. this is deserving of a recall, mazda needs to own their mistakes. *tr

We purchased our vehicle new. the passenger side air bag lights up for no reason. it's intermediate. i have taken it into the dealership and they claim there is a known issue however not a recall therefore mazda will not pay for the expense to repair/fix it. i have asked if the air bag will work if we are in an accident and they cannot say either way. also our engine light is intermediate as well. i've taken it to repair shops who ran a free diagnostic test which states another known issue with mazda with the fuel evaporation line. if mazda is aware of these issues, why don't they repair them at no cost to the owner? does someone have to die first? *tr

2007 mazda cx-7: timing chain and vvt hub started to fail prematurely, leading the car to not be driven and possible engine failure at speed. mazda is aware of this design flaw and possible hazardous situation, but is reluctant to repair at their cost. engine mount #3 has also broken creating unsafe situation. *tr

While driving down road timing chain jumped causing severe internal engine damage ... (bent all valves) approximately $8000. to repair! *tr

I was accelerating to merge into expressway traffic when i heard a loud whine/squeal from under the hood and the car lost a significant amount of power. the noise was so unexpected and unrecognizable that the shock i experienced when i heard it caused me to tense up and veer off to the right. fortunately as i was on a ramp there were no vehicles to the right of me to hit. i was able to get up to highway speed by gradually accelerating on the shoulder before merging and then exited at the next exit. the vehicle is now at a mazda dealership and i've been told it was a turbo charger failure. my research into this issue on this make, model and year, has proven that this is a known issue for mazda and they have extended their standard warranty coverage to owners for additional months and/or miles. there has not been a recall however and i think that considering the number of these incidents that have occurred, one would be warranted. *tr

Tl* the contact owns a 2007 mazda cx-7. the contact stated that the variable valve timing (vvt) burned out and caused smoke to emit from the exhaust pipes. the contact took the vehicle to a dealer for a diagnostic test. the dealer stated that the vvt valve timing chain was defective and replaced the vvt valve timing chain. the contact stated that the vvt valve timing chain was replaced four times prior to the recent failure. the failure mileage was 70,000.

Tl* the contact owns a 2007 mazda cx-7. the contact stated that while driving 65 mph, the vehicle overheated and the turbo system malfunctioned, causing the engine to sludge and the vehicle to stall. the vehicle was taken to the dealer, who confirmed that there was sludge in the engine and advised that the engine would need replacing. the engine was not replaced. the failure mileage was 93,000.

Tl* the contact owns a 2007 mazda cx-7. months after the vehicle was purchased, the instrument cluster gauges flickered and the vehicle stalled. the vehicle was towed to the dealer. the mechanic replaced the timing chain belt and the engine assembly. the dealer provided no invoice of the repairs. months later, the failure recurred. the vehicle was towed to an independent mechanic for further inspection and the contact was to tow the vehicle back to the dealer to determine what parts they actually replaced. the vehicle was not repaired. the manufacturer was notified of the failure. the approximate failure mileage was 34,366.

I was experiencing a shake in the steering wheel at high speeds, which we attributed to a tire/wheel/alignment issue. i made an appointment when the check engine light came on. the dealership told me i needed the timing chain (and assorted peripherals) replaced...for the second time in two years. the first time was covered by warranty, but only after i produced the records to show the oil had been changed regularly. the second time was not covered under warranty. it cost $1500 to replace the entire assembly that was less than two years old. the dealership has recommended ignoring the manual on oil changes (every 7500 miles) and changing it every 3000 to hopefully catch any further issues. they said because the turbo runs very hot, it burns up the oil quickly. my car was very low when i took it in. they also said the check engine light will not go on due to low oil, but only for low oil pressure. the other issue i had was related to the rear view mirror. i have the auto-dim with compass, which was installed by the dealer when i bought the car. it has failed twice and been replaced under warranty. the second time was around 65k miles. less than a month after my warranty ran out, the entire mirror fell off the windshield. in the early 2007 models, the clip that holds the mirror can not be replaced if it breaks. i had to have the entire windshield replaced in order to re-attach the mirror. i was told even though the mirror would have been covered since it had just been replaced, the windshield was not covered. that was another $250 to replace a perfectly good windshield just because the clip couldn't be fixed. i have seriously considered just trading this car in because i doubt very much it will be worth more than scrap value in a few more years. *tr

We were driving home on christmas eve going about 65 mph when the cars engine just died. we lost all power to the car including the power steering. thankfully we were on a straight stretch and due to time of night there were not many other cars on the road. we were able to coast to the side of the road safely. the car was towed to a dealership where it was discovered the timing chain broke and damaged the engine in the process. after researching this online i discovered hundreds if not thousands of complaints about a broken timing chain that required replacement of the engine. some of these complaints were as early as 30,000 miles. there was even discussion about a recall on the timing chain from mazda saying that it was defective but mazda was not always honoring this recall. obviously based on these complaints there is a problem with the timing chain in the 2007 cx-7 that needs to be addressed. mazda is not doing anything about it and trying to get out of the mess they created. *tr

Check engine light due to the egr valve = exhaust gas recirculation valve being stuck in the open position with 51k miles. the dealership replaced the valve (part number l3k9-20-300a) and the gasket (part number lf6t-20-305) for $882.63 being that it was not covered under my certified pre owned warranty or my extended warranty since it is part of the emissions package i paid, in full, out of pocket. i have checked several online forums and have seen this is a common occurrence for 2007 cx7 between 25k and 55k miles. i think this is a much larger problem than regular wear and tear requiring an investigation. *tr

Driving east across the bay bridge from sf, the engine made a wheezing noise. after a mile the power dropped, and the car would only travel at 30 mph. no engine light came on to warn of this, even during the event. at this point it was obvious that it needed repair attention, and we found a mazda dealer/repair shop relatively close by to drive it to. once they had a chance to diagnose the problem, they reported to us that engine 'sludge' was to blame. the timing chain had been rubbing, and the vvt actuator had been compromised. turbo galleys were also plugged. in jan. of this year, mazda posted an extended warranty for cx-7's timing chain and vvt. however, the dealer informed us after checking with mazda that we were not eligible for the warranty. gaps in our history of repair was the given reason. after an appeal, the rep from mazda said the highest authority had reviewed the claim and again declined to help. we have read numerous complaints from other cx-7 owners with the same problem. many of them have also been denied the use the warranty that mazda has extended.this is a vast and scary problem with this vehicle. *tr

Vehicle was traveling north bound when check engine light came on as well as at on the driver console, the car would not accelerate or shift from 3rd gear in the middle highway causing the vehicle to decrease in speed. *tr

While driving the car the ac compressor made a noise and ceased to work. i noticed a strange smell coming from the car followed by smoke coming from the engine compartment. i pulled over and opened up the hood to find smoke pouring off of the ac compressor and a large amount of sparks shooting off of it. this indecent occurred 4 months after the extended warranty on the ac compressor ran out. i'm not sure why this isn't an issue that is subject to a recall, as there was a very real danger of a fire breaking out. *tr

The vehicle suddenly stopped running while traveling at 65 mph on interstate 95. the vehicle was safely moved to the side of the road where it was then towed to the dealer where it was purchased. the service representative indicated that the engine would have to be opened at a cost of $500 to determine the cause of the problem. they suspected that the timing chain had broken. after consulting with mazda customer service, i was advised to have the vehicle towed to a mazda dealer. the vehicle was towed to thompson mazda in baltimore, maryland where it was confirmed that the timing chain had broken and that the engine would have to be replaced. mazda had provide an extended warranty on the timing chain for 7 years or 70,000 miles. the warranty indicated that if there was a timing chain noise to bring into a mazda dealer to have it serviced under the warranty. at no time was there a noise experienced from the engine. mazda also indicated that the vehicle had to have service records to be covered. since the vehicle was purchased used in april 2011 we only had our service records and the car fax service records. mazda indicated that because there was a gap in the service records, between 31000 miles (the last record shown by car fax) and 54000 miles (when we had purchased the vehicle), they would not cover the cost of replacing the engine. it is my belief that mazda knew there was a defect in the timing chain and had they been proactive in recalling the vehicle and replacing the timing chain the engine would not have had to be replaced at a more significant cost of $7,200. *tr

My husband was driving the vehicle down a backroad highway going 60 when all of a sudden the car stopped. there was no notice, no noise nothing. the pos was towed to the local mazda dealership. the looked at the vehicle and said "timing chain..$3000". ok, not what we expected but fine, fix it. 24 hours later, they called to advise that the engine is blown $7000. i contact the mazda customer service ( aka people who are trained to tell you that you are sol) to see if there was any recall or any other things that may cover this. no, nothing but a extension was mailed jan 2012 to advise that the timing chain was extended for repair. no notice was received and the address they had on file was correct. so here we sit with a worthless pos that nobody wants to take responsibility for. i would rather have it sit in the drive way and we share 1 vehicle than put 7000 into this car. i see that we are not the only people that have been taken advantage of by mazda. has anyone called recently into customer service to hear the list of recall notices? it take 8 mins for the automated system to list them all. this company needs to take responsibility for it's worthless machines! if a class action lawsuit ever comes out, i will join in a heartbeat. can the nhtsa please look into this? i know that we are not the only people ... no time in life should an engine need to be repaired with only 76k on it!!! *tr

While driving home from work 8/23/12, my husband noticed that the a/c was not cooling and that the engine started making a squealing noise. he stated that the a/c compressor was failing. fortunately for us, he made it home safely. if it failed completely while driving, the car (or he) could have died in the middle of the interstate.we had received the extended warranty notice for the a/c compressor. so, we took it to our local mazda dealership/service department for repair. the technician stated that we had just exceeded our warranty coverage. our vehicle turned 5 years old on 6/30/12 and has 60,598 miles. he stated that we would have to contact the mazda corporate office to request assistance. the corporate representative stated that they would contact our dealership and take the matter under review. she stated that if they denied the claim there was no one else at mazda that would discuss this with us. i agree with other complaints filed to date...apparently, someone will have to be killed before anyone issues a recall. *tr

My mazda began making a clanging sound at ignition. i took the mazda to sussman mazda in abington, pa. i was told that thought the warrant 5 yrs/60,000 miles had expired. however, mazda had extended the warranty on the vvt actuator and timing chain due to this being a know problem. i was asked to produce all maintenance records on the car. i did not have every single service record and was denied repair by mazda. i called the mazda corporate office and spoke with a representative. the representative told me that my claim was denied. i asked to speak with a supervisor but i was denied. i called back and was told that a supervisor would call me back on 08/30/12. it is 10pm and no one has called me back. it appears that mazda is doing everything possible not to repair a known defect on the mazda cx7. there are numerous complaint online of many cx7 owners going through the same situation that i have. i cannot drive the car due to fear off the timing chain failing. *tr

Felt slight jolt, and immediately less power, then engine just stopped. my opinion is that the timing chain first "jumped" a tooth, then failed altogether. i was able to coast safely off to the shoulder, where i called for a tow. car was flatbedded back to the dealer at my request, as they have done all work on the car since day 1. dealer stated several days later that engine had no compression in two of the four cylinders, and a remanufactured engine would be required at a cost of $6400.00. later, having researched this, it is a common problem and seriously premature for this mileage and for a car driven moderately and on which all recommended maintenance has been performed (by this dealer). i stated mazda should stand behind this and contribute all or part of the repair bill. several days later, dealer states mazda refused. *tr

I drove 200 miles stopped the car to get something to eat, when i restarted it a loud whistling noise came from engine and wouldn't stop. called roadside assistance and it was towed 2 days later because it happened on a saturday night. it took 3days for it to be fixed and i'm not sure it is running properly. i also had the timing chain replaced at 60,000 miles. i will never buy another mazda. *tr

While driving on interstate highway, loud ticking and whirring sound came from engine. black smoke came from rear tailpipes and white smoke from under the hood. vehicle lost power and stopped. *tr

Driving on my way to tennessee, the car had a major power loss and screeching noise from inside the engine bay. the car was taken to the closest mazda dealership and was told that the turbo had to be replaced due to engine sludge. the car had regular oil changes using the proper amount and oil weight. mazda had a recall involving the turbo and they did not honor it because i was about 1000 miles over the extended warranty. *tr

My husband was driving home when he suddenly heard a loud whining noise then lost power. on the way to the dealer, he noticed it was smoking. *tr

While driving with my ac (air conditioning) on, it suddenly started blowing warm air. the car filled up with a burnt tire like smell and i quickly turned the air conditioning off. after giving it a few minutes and parking my car on a shoulder lane, i turned the air conditioning back on to see if it's going to start working again (while the car was still running). my ac was still blowing warm air but now there was a loud noise what appeared to be coming from the engine along with the burnt tire like smell. i decided to return home and have my husband take a look at it before i contact the dealership service to fix it. as my husband open the hood of the cx7 and i turned on the ac there appeared to be alot of sparks coming from the ac air compressor, right beside the engine. this looks as if it can potentionally set on fire. mazda did send out a warrenty extension letter (ssp 81) back in 2010 for this very same issue. this warranty extension was covering vehicles up to 5 years/60000 miles. *tr

Tl* the contact owns a 2007 mazda cx7. the contact stated that when driving over 20 mph, there was a loud noise coming from the engine. the vehicle was taken to the dealer who stated that there was a faulty turbo engine charger which needed to be replaced. there were no recalls for the vehicle. the vehicle was not repaired. the manufacturer was notified who confirmed that there were no recalls and offered no further assistance. the failure mileage was 78,590.

On 7/11/12 my wife was driving on the entrance ramp to the fl. turnpike when her mazda cx7, 07 engine turned off completely without warning. she was on a one lane road with a blind sided curve when this happened. a 18 wheeler truck was coming up behind her and almost rear ended her vehicle. fortunately the driver of the truck was able to stop before hitting my wife car. after a investigation of the engine problem i found out that it was a bad timing chain that caused the vehicle to shut off the way it did. i called the mazda manufacture and they told me that they were aware of the timing chain problem and that's why they sent out letters for an extended warranty on the timing chain problem. the also stated that the only way they would replace the part is if i could show records of every oil change that was done on the car from the time of purchase. being that i purchased the vehicle used i am not able to show all the oil change records they request. the point is that the manufacture recognized that there is a problem with the timing chain. they should be doing a immediate recall on the car to fix the problem before somebody gets seriously injured or killed..if you can i ask you to please help with this matter.. *tr

Vtt timing chain broke on this vehicle which could have resulted in a horrific accident if the car had been mobile. mazda has acknowledged that this engine component is faulty, because they issued a warranty extension to 72,000 miles in january 2012. this sort of engine failure could lead, and may have already lead to numerous accidents if they vehicle stalls while on the interstate or other roadways. mazda should recall the engine part and reimburse customers who have had to pay for this mechanical failure. *tr

The air conditioner compressor went out. the vehicle began to have acceleration issues and started smoking like burnt rubber. mazda has extended the warranty to 60,000 miles but refuses to replace the compressor beyond that mileage. *tr

Tl* the contact owns a 2007 mazda cx7. the contact stated that she had to replace the turbo in the engine four times due to sludge build up. the contact also stated that the most recent turbo failure caused the engine and transmission to fail. the contact took the vehicle to a mechanic and was informed that it was unusual for this failure to occur. the contact stated that the first turbo failed at 33,000 miles, the second at 58,000 miles and the third at 83,000. the manufacturer stated the turbos were not covered by warranty. the vin was not available. the failure mileage was 33,000 and the current mileage was 90,000.

I called a mazda car dealership to let the know i receive a recall letter and to make an appointment for my mazda cx7, the service man said if the car was not making any noise or smoking i didn't need to bring the car in. after weeks by after taking the service man advise i was driving on the highway in my cx7 mazda with my 6 month old grandbaby in the back seat all of a sudden pressing on the gas, the car just shuts off without any kind of warning in the middle of the highway; this highway is normally very busy especially with 18 wheelers, luckily there was enough power left for me to pull over out the highway before the steering wheel locked up. after waiting for tow truck driver in the heat with no ac and a 6 month old baby car was towed to a mazda dealership, which was closed. the next day serviceman calls me and tells me the timing chain broke, destroyed the engine and it was going to cost $4000 to be repaired,i had to bring receipts for oil changes, there was no sludge found; mazda offered $1000 as a good gesture, if they had found sludge they wouldn't have offered that. my car is still there; i can't get the car out because i have to make car payments and rent cars to get back and forth to work. what is it going to take before someone steps up and have mazda corp held accountable for these malfunction parts. will someone have to loose their life before someone recognizes that there is a major problem!!!! there are to many complaints on line for the same reason for this not to be an issue!!!!!! i've been in contact with lawyers and the media i feel the public needs to know how this corporation is treating the consumers. *tr

My 2007 cx-7 started making a loud banging noise when i started it (may 7,2012). i brought it to the dealership to have it checked out and they said it was my timing chain & actuator (vvt) and it would take $1350 to repair. i paid the money and it was fixed in a couple of days. on june 7th,2012 i started to realize that my ac was not working, but had decided to wait a little bit to have it fixed because i was still hurting financially from the last fix a month ago. than on june 9th, 2012, i went to start my vehicle and it sounded like it was about to explode. i live in the country and the closest dealership is at least 50 miles away. so i brought it to my local repair shop and they told me my turbo is blown. the mazda dealership wants $80 to diagnose it and $5000 to fix it (that doesn't include my towing fees and the cost of fixing the ac). i've read all of the complaints online and everyone is saying sludge build up and mazda wants the receipts for all of their oil changes. i have all my receipts for the synthetic oil changes that i have had done to the vehicle on time (not to mention only filling the car with premium gas). unfortunately, my car is up to 100,000 miles and they only extended the warranty to what...70k? so basically i have a car that i paid $16k for and is completely useless to me only after 100k miles. from what i've researched vvt's are not supposed to go out until what 250k-300k miles? and it seems a bit ridiculous for the turbo to go out after 100k miles.... *tr

While driving our cx-7 stopped running right in the middle of the road, we have found out that is a known issue with mazda cx-7 vvt pin/timing chain breaking. we were able to get the car stopped, but it was in the middle of the rode and was a hazard not only to our car, but other cars coming up behind us. we were unable to move the car and had to wait for a tow truck. of course, mazda won't do anything to remedy the situation because the warranty has passed...even though they knew the problem existed in 2009. someone will get killed one day. *tr

On may 18th i took my car to the mazda dealer in nj for a timing belt recall and was replaced. on may 28th driving on the highway the a/c stopped working, the warning lights came on and immediately the car stalled. i then had it towed to the same mazda dealer. the next day they told me that my engine was blown and it was going to cost me $7,476.79.i have always serviced my car every 3,000 miles, my car is only 6 years old and only has 57,040 miles. i took it to an engine expert and told me that the engine was defective. mazda should recall all cx7s from 2007. it is obvious that all of them came out with a defect. *tr

Tl* the contact owns a 2007 mazda cx7. the contact stated that while driving approximately 20 mph, the vehicle suddenly stalled. the vehicle was towed to an independent mechanic where it was found that the vvt timing chain had failed and needed to be replaced. the contact was also informed that the turbo had failed and needed to be replaced. the vehicle was repaired. the approximate failure mileage was 56,800.

Vvt and timing chain replacement needed mazda knew these to be defective parts but only issued warning to me just this month and now that im over the mileage i have to pay for cost of replacing both ... why hasn't the safety board looked into this very dangerous issue that will eventually cause someone to lose their lives ..... this most be addressed now!!!!!!!!!!!!!!!!!!!!!!!!!! *tt
