Problems with 2007 Nissan Frontier POWER TRAIN

Vehicle is well maintained with 115,000 miles odometer reading. this is the 2nd time the rear axle seas have failed, resulting in gear oil soaking rear brakes, resulting in oil contamination of brake pads and rendering the parking brake ineffective. the reason was explained by nissan as a rusted $14 breather tube in the differential housing causing pressure build up to ruin the $7 dollar seals. the result is a repair any where fro $1500 for a difficult axle pull to get to the seals or up to$6500 to replace the entire rear assembly. the problem with seal replacement is it is difficult and time consuming and must be performed perfectly or the seals will leak again. the root cause is a poor breather system,. nissan is aware of this problem and refuses to acknowledge the defective design and application. continued use will cause premature rear brake failure and too much stress on the front brakes to stop the vehicle.

Drove a very short distance near my work and heard a bubbling sound in the engine compartment, knew immediately something was wrong with the radiator. a few seconds later it was like a small explosion and i was able to park. the goo coming from underneath was unlike anything i had seen before. i had usaa tow it off, dealership said crack in the radiator caused fluids to mix and corrupt the transmission and found out 15 days later that nothing would be covered. didn't know about the massive, wide-spread problems with this exact scenario. dealer didn't know, insurance and adjuster never said anything. wasn't until a small town mechanic told my mother-in-law, that we heard about these issues from other nissan owners. i am hesitant to have factor parts put back in it if, according to others, the same problem could re-occur.

Transmission total failure. radiator line broke and mixed into transmission, destroying it. occurred while driving up a hill.

When entering hwy 17 (70 mph speed limit) i pressed the gas pedal to the floor to enter oncoming traffic. instead of increasing speed the truck stalled. i pulled onto the right side emergency lane in order to prevent traffic from running over my vehicle. i placed the transmission in park and it seemed to smooth out . motor was running with excess rpm's and transmission was slipping. this was a near accident. i could hear cars behind placing on brakes and blowing horn. when returning home was told by nissan dealership radiator cooler and transmission had to be replaced due to faulty lines. nissan should have recalled this problem.

Entering 4 lane highway with 70 mph traffic. kicked frontier into passing gear to enter ongoing traffic. frontier stalled and slowed instead of increasing speed. transmission slippage and jerking caused motor to increase rpms. i had to move my truck over to right of paved lane and onto pulloff area in order to prevent accident. i was told at the nissan dealership that i had transmission damage due to radiator fluid leaking into transmission . it cost me $2500 to repair a problem that could have cost lives. i understand this was a problem that was not recalled by nissan.

Transmission and coolant mixed causing the transmission not to shift properly in traffic. nissan is aware of their faulty components and should be forced to recall and fix, at their expense.

Tl* the contact owns a 2007 nissan frontier. while the vehicle was being serviced for an oil change, the contact was informed of a leak in the radiator. the vehicle was taken to the dealer where it was diagnosed that the radiator was defective and was leaking fluid into the transmission. the vehicle was repaired. the manufacturer was made aware of the issue. the failure mileage was approximately 109,000. updated 01/27/17*lj updated 01/31/17.*jb

My radiator had failed causing transmission fluid to enter the coolant and coolant to enter the transmission. once nissan replaced the radiator and flushed out both systems, the transmission seem to drive ok, and the nissan dealer said it seems to be ok. after driving the vehicle for a month the transmission has developed slippage due to the previous radiator with an internal transmission cooler that caused internal damage to the transmission. if nissan had built the truck with an external transmission cooler separate from the radiator, i wouldn't have had an issue with the transmission once the radiator failed. as an ase certified mechanic with working in the industry for 10 years, also serving in the military as a maintenance mechanic, and with all the different models of vehicles that i have owned; have i ever had this problem where one component fails that would cause me to replace a transmission. i am starting to believe that nissan is not any better than owning any other car, as the technology seems to not be getting better but more costly to us the consumers. the vehicle was drivin at about 30 mph when the truck temp gauge elevated, and coolant burping out. i immediately shut it down to check and discover the issue was the radiator. once taken to the shop by tow truck the shop said the transmission fluid had coolant inside and transmission fluid inside the engine coolant area and passages.

Transmission will not go into gear due to coolant leaking into transmission. it is a manufacturer defect that nissan has known about, but refuses to fix. they do not tell the buyer of the looming catastrophic failure, and continued to manufacture the vehicles for several more years even after discovering the problem, probably because it fails after the warranty is up. i now have a truck that i bought just a little over a year ago for $17000 that will not move. the cost to fix the problem can range anywhere from $4000 to $10000 depending on how much damage was caused by the defect. if it were to have been in a wreck and that much money in body damage would have occurred it would be totaled. how ever since it is a mechanical issue i am stuck paying $360 a month for a useless vehicle, that even if i could afford to get it fixed, i would be putting way more money into it than it is worth. when i purchased it from the nissan dealership it had an as is no warranty tag in the window, but that was not true. nissan had a warranty for that specific problem, but the dealership did not tell me. when i called and asked the service department, the service writer pretended not to know anything about it until i started grilling him about it. he then admitted it was a big problem in 3 of their vehicles, then told me it wasn't his problem, it was sales problem and transferred me to them. i talked to the manager, he said that the extended warranty nissan offered, the one they neglected to mention, expired the month before my transmission failed, and even then i would have been out $2500 for a known defect that they continued to put in the vehicles for several more years. i was lucky it failed in a parking lot and not when i was pulling out into traffic where i could have been hit by another car and injured or killed! this problem is not the consumers fault, it is nissans!

Cracked radiator leaked fluid into the transmission cooler ruining the transmission.an issue nissan knows about, yet does nothing but extending a bogus warranty. truck has 68k.

Tl* the contact owns a 2007 nissan frontier. while driving the vehicle, a clunking and stuttering noise emitted from the vehicle. the contact took the vehicle to a certified mechanic and dealer who diagnosed that the transmission failed. the transmission and main computer needed to be replaced. the vehicle was not repaired. the manufacturer was not notified of the failure. the contact stated that nhtsa investigation number: dp12004 (power train) was directly related to the failure. the approximate failure mileage was 65,000. ....updated 07/05/16 *bf *cn

Nissan is aware of leaking radiators and not until a class action lawsuit was filed they did not take responsibility and only help pay with a copay if the vehicle is less then 90,000 miles. which is ridiculous because it should it be unlimited mileage for that type of repair. radiator leaked coolant fluid into transmission and corroded and broke seals on transmission caused it to brake and have car shut down

Takata recall transmission failure due to water damage of transmission valve body due to coolant leakage from radiator into transmission. i began to notice a vibration around 1200 to 1600 rpm that would smooth out at higher rpms.

Transmission failed due to coolant intermixing with transmission fluid. this is the second time this vehicle has had catastrophic transmission failure due to a crack in the cooling system. first time was just over the warranty so i was forced to pay a $2500 copay. the vihicle started showing signs of a secondary failure just prior to 100000 miles and when i brought it to the dealer they lied to me and said there was just residual oil in the radiator from the first failure... now i am past any warranty copay and the transmission is failing at just 100500 miles. that is just two years (less than 18000 miles) after they replaced the radiator and transmission. this is unacceptable that consumers are being forced to pay for a known issue of poor engineering especially when it was supposedly fixed by the dealer with nissan parts. they have obviously not fixed the problem but just replaced with another defective part. on top of that they denied there was a problem to so i would continue to drive the vehicle until it was past the extended warranty (from 2012 class action lawsuit). while there was no accident in either indecent there was a near collision the first time as i was in the middle of a busy intersection and the second there was traffic behind me that had to avoid rear-ending me as the vehicle stopped, this is a dangerous defect that could result in injury or death.

My truck stopped running as i was getting off the highway. i tried to put it in gear and it wouldn't go. i turned it off and on couple of times til i got it to slowly drive off thr traffic lane. i parked it then had it towed, turned out the radiator coolant has leaked into my transmission. it's been in the shop for over 3 weeks now and the repair cost is going to be around $6500.

Tl* the contact owns a 2007 nissan frontier. while driving 30 mph, there was an odor emitted into the vents and the contact noticed smoke under the hood. the contact coasted over to the side of the road and noticed oil and antifreeze fluid spilling from the reserve tank onto the transmission. the vehicle was taken to the dealer where it was diagnosed that the spill caused the transmission and radiator to fail. both the radiator and transmission needed to be replaced. the vehicle was not repaired. the manufacturer was not notified of the failure. the vin was unknown. the approximate failure mileage was 94,000. updated 04/14/16*lj updated 04/18/16. *jb

Transmission fluid cooler failed causing water to to get into the transmission fluid which damaged the transmission computer valve body and other transmission parts. after looking @ numerous complaint on the web i have learned that this has been a common problem that nissan is aware of. i am very disappointed that nissan did not send out any notification that there was a problem with this cooler failing. i read where they extended the warranty on some vehicle but no notifications were sent out to consumers who owned affected vehicles. even if they did not do a recall it would have been better if they would have warns consumers of the possibility of this happening. it's much less expensive to change a radiator than to rebuild or replace a transmission! fortunately my transmission went just after i made home from a trip. now i am stuck with over $3500.00 transmission rebuild that could have been avoid if nissan had done the right thing by letting people know that they had problems with their transmission coolers.

Radiator fluid mixed with transmission fluid due to faulty radiator, beyond useless extended warranty, resulting in my burden to pay, according to nissan a 2500.00 dollar deductible, plus taxes. nice, my truck has only 49,000 miles on it, no off road use, and now getting to the point of useless. thanks nissan. oh, don't forget the towing charge to the nearest dealer over one hour away for repairs. i just started with transmission symptoms of intermittent grinding with overdrive engaged on the shiftier. took my truck to garage for inspection, they checked the transmission fluid and, ya you guessed it, radiator fluid mixed with it.

The problem began as "shudder" resembling what is felt when the car moves onto the "rumble strip" near the shoulder of the road. this occurred while traveling at lower rpms (1500 - 2000) at average highway speeds in 5th gear (55 - 65 mph). since the vehicle is primarily driven in town at lower speeds, the "shudder" occurred rarely and was not initially identified as a problem. over the course of several months, the problem began occurring more frequently and at lower speeds, but always at lower rpms (1500 to 2000) and in all gears. as the shudder worsened, the vehicle also began to shift more roughly, often jarring as it moved from one gear to the next. (this occurs at all gear changes.). the vehicle is now "slipping" quite badly as it moves from 4th to 5th gear. the vehicle was taken to a mechanic who diagnosed torque converter problems and possible transmission failure. the mechanic has recommended replacement of the transmission. it appears there may have been a valve body failure in the transmission and cross-contamination of the coolant and transmission fluid.

The transmission failed due to a known design flaw that allows collar from the radiator to leak into the transmission causing it to fail. on my vehicle it failed at 100,800 miles, just barely outside warranty. it will no longer climb hills and has great difficulty gaining initial momentum on flatter roads. it doesn't stall, just sits in one place, rolls backward instead of forward, or excelerates like a 3 toed sloth. the first time it happened we were driving up steep driveway and it just stopped moving. the second time we were on a less steep busy roadway and we're forced to roll backwards in traffic until we could find a place to turn around. issue had not been specifically noticeable prior to this.

Around 3 months ago i started noticing between 1000 and 2000 rpms and usually between 40 and 60 mph my vehicle would shake like i was driving on rumble strips. turns out i had a cross contamination issue with coolant and atf. looking in my radiator looked like a strawberry milkshake. also dropped the transmission pan and found a brown shiney mixture of atf and coolant. i immediately went out and bought a new radiator and fluids for my truck. total cost around $400 so far. after the fluid flushes and new radiator truck ran good for about 1700 miles. about a week ago 01/20/2016 a slight rumbling started again. 2 days ago the issue turned very severe. rpms were staying very high around 3000 then would get a very violent clunk as the transmission shifted gears. this happened multiple times. i drove the truck yesterday and was sitting in traffic and went to start went light turned green. rpms went to almost 3 with no movement from the truck then all of a sudden truck gave the violent clunk again and slammed into gear and started moving. i did not drive the vehicle today in fear of a catistrrophic breakdown or worse. like a transmission lock up at 60 mph causing an accident. i have been shopping transmission shops and it looks like definitely need transmission rebuild or replacement at an estimated fee of $3000 to $6000. this is for an issue that nissan has been aware of and failed to communicate or take responsibility for with their customers. issue seem to be when driving straight city or highway at the above speeds and rpms range.

With no prior warning, transmission failed on the vehicle. this has now happened twice, in november 2013 and december 2015. in both cases, vehicle lost all transmission of power to the drive train. in both cases, transmission fluid could be smelled when the hood is opened afterwards. manual clutch continues to function perfectly, and guage shows proper rpms, but the vehicle will not move. in both cases, vehicle was moving in a straight line, once at freeway speeds of about 65 mph and once in a residential neighborhood at approximately 25 mph. because of the sudden loss of power, especially on the freeway, the problem caused a sudden slowing which affected the traffic around me.

Trans cooler rupture and mixing coolant with transmission fluid. ruined transmission/computer/radiator and left stranded on road. very expensive fix for a problem that nissan has with 2005-2010 models and were aware of. nissan deceived the consumers and has not done enough to satisfy customers. i will not purchase another nissan vehicle. i think they need to send letter to each vin with proper instructions on how to fix this issue so it does not happen again.

My frontier died on 12/6 / on 12/7/2015, i had it towed to the boardwalk nissan and paid $100 to have the problem diagnosed. i was told the repairs would cost $10,500. the radiator caused the transmission to go out in turn causing the computer panel to burn out. i asked the service adviser was there something i could've done to prevent the problem. he said no, the problem happens. i then had the truck towed home. now, i find out there was a problem that nissan should've known about, had they made the repairs to the radiator, my truck would be working today. this makes me angry. it makes me angry that i just paid $317.44 to replace tire sensors that may not have been needed!! the radiator issue resulted in a $417.44 expense that may not have been necessary ($100 for a diagnosis). the truck was parked in front of my house. i attempted to start the car on 12/6/15, it wouldn't start. thinking it was a battery issue, i waited until the next morning; only to find out it wasn't the battery. i called boardwalk nissan and had the truck towed to the dealership for diagnostics & repairs only to find out it would cost me $10,500.

Transmission failure due to coolant mixing had to have the valve body replaced along with the tcmand new radiator. vehicle cut completely off and would no longer start. after failing to excelerate past 40mph.

My transmission failed to water in transmission due to faulty radiator because of recall i was never informed of untill i researched it after it happened 10 /17/15 it stayed in high gear on hwy 98 i almost got hit 2 or 3 times i had it towed to advanced trans. spanish fort , al invoice #10892 water in trans. 3996.89 for rpairs

These vehicles contain a defective radiator cooler tank that ruptures and forces coolant into the transmission through the cooler lines. when the coolant mixes with transmission fluid it creates a frothy liquid that eats valves, errodes seals and causes corrosion. it's toxic, irreversible and will eventually kill the 5-speed automatic transmission. which it did

Transmission damage attributed to contamination by engine coolant. the source of the contamination is a cracked atf line that runs through an engine coolant chamber in the radiator.

Purchased the truck 8-1-2015, drove it about 2 months (1700 miles). while driving and turning left with oncoming traffic, the transmission hesitated nearly causing and accident. took the truck to nissan to be checked out. they diagnosed that the radiator cracked causing contaminatiion of coolant into the transmission. since the transmission cooler was built inside the radiator. which after reading a little research was a known problem by nissan for 6 model years (2005-2010).

Tl* the contact owns a 2007 nissan frontier. while driving at various speeds the vehicle would hesitate to shift gears. after examining the vehicle, the contact discovered that transmission fluid was present in the radiator coolant. the cause of the failure was not diagnosed or repaired. the manufacturer was not notified. the vin was not available. the failure mileage was 80,000.

Was stationary ready to go to next appointment put it in drive and it would not go. engine reved but not moving. was told at dealership coolant has gotten into transmission. needed new transmission . after repairs, headlights and windows did not function correctly.

Tl* the contact owns a 2007 nissan frontier. while driving 40 mph, the vehicle shook violently. the contact coasted to the side of the road and was able to restart the vehicle after thirty minutes. the contact also stated that the radiator cracked. the failure recurred numerous times. the contact was advised by the dealer that the vehicle needed a new transmission and radiator. the vehicle was not repaired. the manufacturer was notified of the failure. the failure mileage was 82,000.

When the truck transmission shifted into 5th gear there was a grinding noise in the transmission. this problem has been repccuring and getting worse. the nissian dealer verified it is due to contaminated transmission fluid due to a leak in the cooling radiator.

My 2007 nissan frontier heater would not warm up when idling. i took it to the dealership in december 2014 and they flushed the lines. six months later the transmission began to slip. i took it back to the dealer and they informed me that due to a manufacturer's defect engine coolant leaked into the transmission and destroyed it! i would need a new transmission and radiator. because the vehicle was now 8 years old, the warranty will only cover part of the cost and i am responsible for $2,500. after researching this problem, i found that one of the warning signs was a heater that would not warm up while idling. the vehicle could have been fixed in december of 2014 and covered fully by warranty, however, the dealer did not warn me! now, nissan says there is nothing they can do! i'm frustrated to say the least and have purchased my last nissan!

The transmission doesnt shift down as it needs to when it is called for,and a chatter happens when it does shift down.

Driving when car stopped moving and started rolling backwards. had to put car in reverse. intermittently got it in drive. car was making a humming noise.

Truck started to vibrate like i was driving on a rumple strip around 40 mph. it seemed like the overdrive was struggling to engage or the automatic transmission couldn't find the right gear. i checked the atf and it was a red strawberry milkshake consistency that is often described when there is water contamination. this is a common problem that nissan refuses to recall. it has just over 90k.

I purchased a 2007 nissan frontier in 2013, and just prior to reaching 109,178 my transmission started slipping badly so i took it to my local mechanic and he discovered that my "sealed" transmission was missing two quarts of oil and there were no signs of leaking on the external portion of the transmission. he replaced the missing oil and after a week of driving the transmission was slipping again. he checked the oil level and again it was quart low and slipping badly. it was then i started researching nissan transmission problems and discovered that what i was experiencing was a well known (by nissan) problem with their transmissions. now at 109,275 miles the transmission has completely failed and it all could have been prevented had nissan fixed the well known problem before they sold the vehicle to me. funny the salesman that sold the truck to me suggested that i purchase a "power-train" warranty "just in case" because it was 4wd, i find that very ironic. i purchased the warranty and now i am being told that the repair cost for the blown transmission may not be covered because the transmission cooling radiator is the cause of the failure. i feel that nissan is fully responsible for whatever the cost is to fix the transmission because of their negligence in failing to fix the problem prior to the truck being resold.

Tl* the contact owns a 2007 nissan frontier. the contact stated that when the vehicle was taken to an independent mechanic to be serviced, the technician stated that the radiator, transmission, and transmission control module needed to be replaced. the vehicle was not repaired. the manufacturer was not notified of the failure. the failure mileage was 100,000. the vin was unavailable.

I bought a used 2007 nissan frontier crew cab at hyundai of roseville, ca a year and half ago on jan 2014 and they never disclose to me that this car was known for coolant leaking into the transmission and eventually destroying it. after buying this, i only drove it for about 8,000 miles and this problem hits me june 2015. i bought it for $12,500 and still owe $8,000. the costs to repair this according to nissan would costs me $7,500. i bought an extended warranty for $1,200, but it would not be covered because this is a "known pre-existing problem or defect by the manufacturer." so, this used frontier would costs me over $20,000 which is about what the new ones are going for. this is terrible and i need some kind of justice. either nissan, the hyundai dealership that i bought this from and or the extended warranty company need to pay for this. nissan should pay because this was a known manufacturer defect. hyundai dealership that i bought it from should also pay because they didn't disclose of this known defect. the extended warranty company called buy direct auto warranty should had not offer me a warranty knowing that can't pay for this kind of repair. they should either pay for the repair or give me a full refund. i need justice!!!

I was rear ended 04/20/2015 ,back injury, police report, other driver insurance taking care of bills, no settlement yet. in june, noticed transmission slip & leak in drive way. in repair shop on friday, 07/31/2015. they advised me radiator crack and transmission fluid leaked into radiator. $1,200.00 to repair all. they instructed to do so.

2007 nissan frontier with 140,000 miles started vibrating and seemed sluggish when accelerating. i took to firestone thinking maybe it needed tune up. come to find out transmission is the issue. i have previously had to replace fuel sensor when nissan refused to pay. i was over the mileage by 2000 miles for recall. now i have read about issues with transmission and once again nissan refusing to fix problems. nissan should be taking care of these issues. i will not own another nissan!!! my brother also had a 2009 frontier with the fuel sensor issue and nissan would not pay to fix. nissan knows this issues is occurring over the 100,000 miles and know they have defective parts on vehicles.

Like so many other nissan frontier owners, the radiator coolant got mixed with the transmission fluid. this is factory defect known by nissan. had to replace radiator and transmission since the car was not responding well and was not able to run properly. called nissan three times to ask for some financial support and they denied it. *tr

Tl* the contact owns a 2007 nissan frontier. the contact stated that the vehicle was difficult to reverse. the vehicle was taken to a dealer where it was diagnosed that the transmission needed to be replaced. the vehicle was not repaired. the manufacturer was notified of the failure. the approximate failure mileage was 45,000. updated 11/18/15*lj the consumer stated the dealer advised the vehicle was unsafe to be driven. the vehicle not reversing was the first sign of transmission failure. updated 1/14/2016*js *cn

Transmission was slipping bad, and the coolant was looking brownish red. transmission fluid was in the radiator and through out both the engine and transmission. when i took it to the dealership to get check-out they said my warranty had expired and that this wouldn't be covered. would need to replace radiator and transmission.... costing me $ 2,731.25. although this is a known fact that nissan is having a good amount of problems with various nissan model including my nissan frontier. very unhappy nissan customer of many years..... now i'm starting to have timing belt issues which falls under another nissan frontier problem. will have to get fixed at my own expense. my dealership know these things but are not open about these fact. i take my frontier in for maintenance nothing ever said and never seem to get recall notices either.... *tr

Was driving 2007 nissan frontier when 4wd light came on and check engine light came on. slowed down and came to a stop. when i tried to accelerate, there was no response. apparently, transmission is ruined due to a known defect with the radiator where coolant leaks into the transmission. nissan never issued a recall for the radiator assembly, just extended the warranty to 100,000 miles, leaving the consumer responsible to fixed catastrophic transmission failure. cost $6500. *tr

Tl* the contact owns a 2007 nissan frontier. the contact stated that while driving at 10 mph, the transmission cooler fractured and caused anti-freeze to spill into the transmission. the vehicle was taken to a dealer to be repaired. the details of the repairs were unknown. the manufacturer was made aware of the failure. the failure mileage was 83,256.

A couple of months ago, i began to notice a loud vibrating or shuddering sound at speeds around 35-40 mph. it seemed to happen as i stopped accelerating as if it were trying to up-shift for cruising. the sound began to get louder over the next few weeks before i could get it checked out. it now has a very difficult time shifting at those speeds and when it does shift, it's hard and makes a loud knock sound. it then began to run hot one day so after it cooled i check the coolant level and found that it had a light brown, milky looking substance which felt oily. i've recently discovered a lot of information from people with the same problem explaining that it is cause by the coolant and transmission fluid mixing and damaging each component.

Making a noise when traveling at 35-40 mph accelerating. nissan dealership states it is the radiator leaking coolant into the transmission which is causing the transmission to fail. warranty expired on 12/2014. nissan dealership states a co-pay of $2500.00 is what will be charged to fix. *tr

2012 class action suit extends warranty for leakage of antifreeze into transmission which causes engine to stop running properly and break down. apparently this is a common feature on nissan vehicles. this truck was driven to florida by a college student on spring break. at 79,000 mark trouble started. he drove it home to virginia and bingo the odometer went over 80,000 miles. at 80,300 miles he takes it to the dealership and because odometer is over 80,000 miles the manufacturer requires $2500 owner co-pay to repair what could have been a preventable repair before the transmission tanked. had he taken it to a dealer in florida at 79,000 the whole thing would have been covered. they require written proof of mechanical failure. these vehicles need to come with a warning label. *tr
