Problems with 2007 Chevrolet Tahoe POWER TRAIN

Transmission is not shifting and i see that tens of thousands of people are with the same problem on the particularly suv 2007 chevy tahoe this transmission should be a recall or at least fix it with a low price of less than $500 so we can keep buying these trucks

My strabilitrak and service traction control began flashing on and caused the brake lights to turn off. then it reads, engine power is reduced. this began in november 201. i have taken it three times to be fixed. first i was told it was the throttle body, then a switch gear, then a fuel induction cleaning service. it is still happening, just twice this week. the engine slowing down while on the freeway proves to be deadly. in reviewing comments in the chevroletforum.com many consumers are having the same issues with the same results (a guessing game) why isn't this a recall?

My 2007 tahoe all of the sudden started shaking and bucking while driving with my wife and two small kids (on valentines! wife was not happy). the service engine light came on as well as warning messages saying the traction control failed, check brake system and service stabilink system. it limped to our house and then it stalled and eventually was very hard to start. i took it to the dealership next morning and was told that the #6 lifter collapsed and they needed to check the camshaft to see if that was damaged. i'm still waiting on the call to see what the total damage is but i was told it was the active fuel management system. i also saw a lot of people's complaints online of the same thing. gm needs to own up and recall this issue. the estimate i got was around $3,500-$4,500 to repair this.

Rear end went out at 150k. dash cracked near passenger airbag radio don't work if it's raining

I was driving down the road and i lost all power and all my lights came on on my dash i just about got hit from behind

While driving or idling, vehicle displays error messages stating "reduced engine power", "stabilitrak system disabled" and "service traction control." the engine power reduces and the vehicle hesitates upon acceleration. it is difficult to get the vehicle to accelerate, especially in lower gears. sometimes the vehicle completely loses power in the middle of driving and all control of the vehicle is lost. this has occurred both on city streets and major highways. purchased the vehicle used about 5 months ago and it began doing this at after about two weeks of ownership. took it to a chevrolet dealership and they said the throttle body was sticking and needed to be replaced. the problem seems to be getting worse over the last few weeks. the vehicle is now stalling on a regular basis (about 1-3 times every time it is driven). the problem is worse when it rains a lot outside. i am afraid to drive the vehicle with my children inside because i have lost power on in the middle of a major interstate twice.

I have 3 issues . low power which read a lot of people have the same issue (bad torque converter).bad oil loss. which everyone seems to have .which the won't fix . transmission slipping which everyone is having and is not the transmission it's electrical. i was told to send a complaint in to you guys. i have read alot on this car and these are very common problems with the 07 tahoe and i have all 3. *tr

I was driving in the snow going 5mph and the tires began to spin. the car was in automatic for 4 wheel drive but did not kick into 4 wheel drive so i slid off the road. i was off road on a slight incline and the car wouldnt go into 4 wheel drive. it said service 4 wheel drive and the knob will turn but the 4 wheel drive will not activate. nothing happened other than the car not going to 4 wheel drive when the knob has been turned. *js

My 2007 tahoe sputtered and hesitated as i approached a stop sign. as i stopped stability control / traction control dashlights appeared as well as the check engine , they both blinked and dash read service stabilitrak, and service traction control. as i pulled from stop sign the tranny slammed into 2nd gear with a bang and i was barely accelerating pulled over and shut the car off. when i tried to restart it just turned over. it took a few tries to get it to start, and when it did i smelled a strong smell of unburned fuel from the exhaust. i will contact gm to file complaint as my tahoe has only 97k on it. hopefully it's covered by warranty. *tr

1. lift gate failed and hurt my arm on or about jan 1 2014. i need repaired asap! 2. dashboard cracked above steering column and cracked by air bag passenger side. i need repaired asap. gm refused to acknowledge thousands of consumers having the same effects to their dashboard. 3. timing chain went off time and bent a cylinder which caused serious damage 9/2014 cost of damages at approximate 4500.00 gm refused to acknowledge deficiencies. i paid out of pocket the 4500.00 with no assistance. i also paid 250.00 for estimates at the gm dealer in kingston mass. they refused to help and give assistance on any of these 3 major safety problems after submitting the dealer bona fide report.

The forward sprag unit broke which ended up not only causing the vehicle to come out of drive while we were driving but also caused significant enough damage to the transmission to requite an entire rebuild. faulty transmissions are a very common issue with this vehicle and because the company refuses to back their products and recall the issue, it ends up becoming a huge financial burden on a family. thankfully there was no one following directly behind us when this happened or it could have been much worse. chevrolet needs to take note and stand behind their products. consumers have a right to expect a quality vehicle that should last well beyond 100k miles without requiring this kind of major repair. *tr

I recently experienced a known electrical issue for the first time yesterday. i just had my tahoe at the dealer last week for strange clacking noise under the hood. they stated i would just have to wait until it did it again. yesterday everything went haywire and my tahoe appeared possessed. door locks, gearing shifting was affected making it difficult to drive and steer due to loss of power steering, which could have caused serious risk to others around me and my two children in the car. turning to the internet and finding that i am one of what is probably thousands complaining of the same issue makes my extremely concerned that gm is not looking out for its current and future customers. i will be filing a complaint with the attorney general's office, ntsb and now with the state of nc immediately. not only have we dealt with this issue. we have long dealt with the oil consumption issue that gm continues to say is "normal" consumption. extremely disappointed in gm and how they are handling major component issues. we also own a jeep wrangler and they are been absolutely amazing anytime we have an addressable issue. *ln

Went to dinner and drove home with no indication of any problems. pulled up to a stop sign, stopped and began to drive forward. suddenly we heard a loud bang, the rpm's raced to 4k and the vehicle was stuck sitting at the stop sign. no drive, or 3rd. we were able to move it in reverse and slightly in 2nd but had to strain up hill to get our car and kids home in the dark in 1st gear. got home and checked my transmission fluid because it had been flushed 14k miles ago and i wanted to make sure there was a proper amount of fluid in the transmission not causing this issue. transmission fluid was pink, clean and measured where it should on the dipstick. i researched transmission problems on the internet in which people had the same no forward movement in 3 or 4 but 1, 2 and rev. ok. found out that there is an issue that thousands of people are having with the 4l60e transmission that gm has produced due to a faulty forward sprag component that was built with cheap stamped metal and they released a tsb pertaining to an updated component! i do not tow anything with tahoe and have made it to 113k miles on my transmission. im being challenged to provide records of my transmission service being done. i have worked for a car dealer as a service advisor for 10+ years and have always purchased all of my parts from a gm dealer to ensure my vehicle would run and drive properly. i am fortunate enough though to not have to pay the dealership labor rate as i have one of my technician to perform my services regularly. i just purchased fluid from our gm dealer and had a complete trans flush at 100k miles like recommended by gm. it has been a problem since 2008 and vehicles affected by this causing a tsb release were not due for trans service yet! it is evident that this problem is not due to lack of maintenance but from poor quality parts that gm claims are built to last! junk! *tr

My wife was accelerating from our street onto a major highway when the engine nearly shut down. her speed was reduced to just 5 mph and the dashboard flashed engine power reduced, service stabilitrak, and service traction control. unfortunately, she knew exactly what this was since this is the third time this has happened in this car in the last 18! we took it to our dealer and they tested the vehicle and diagnosed that the accelerator pedal sensor had failed again! we are extremely uneasy with the car now since each time this has occurred, it has been while one of us was accelerating onto a highway or interstate. on the previous occasion, she had to quickly move away from oncoming traffic...with our children in the car. the dealer indicated that they see this problem very often, but not this much in one car. this is obviously a defective part and should be checked into immediately. *tr

After driving approx 3 miles, my "stabilitrak off", "traction control off", abs light, check engine light all came on, simultaneously. my speedometer and other gauges started swinging from left to right and then flatlined, my power locks, "locked and unlocked" . when the transmission shifted, the whole tahoe jerked. when i arrived at my destination approx 3 miles further and turned the engine off, attempted to re start and it wont start. this is the fourth time this has happened in two weeks. i have taken to a chevy dealer twice to diagnose. both times they said they cannot find the cause, and all they can do is reset the error codes. *tr

My vehicle is experiencing excessive oil consumption due to the active fuel management(displacement on demand) feature. the vehicle consumes approximately 1quart every 1000 miles...the oil is burned through the pistons causing blue-ish colored smoke to come out of the tail pipe. the vehicle comes not a drop of oil if the active fuel management is turned off. every single vehicle from gm that i have tested has had excessive oil consumption due to the active fuel management feature. after that feature is turned off, no oil is consumed. 1 quart of oil is burned is as little as 300 miles. this can cause the vehicle's engine to shut off at any rate of speed due to the oil pressure caused by not having enough oil in the engine. general motors has tried fixing my vehicle and others by replacing the lifters, camshaft, pistons, piston rings, etc..this fix has not worked and many vehicles continue to have excessive oil consumption. vehicles affected range from year 2007 and up (present). my vehicle also has various transmission issues which causes the vehicle to shut down in the middle of my driving and greatly increasing the risk of an accident. general motors has had various repairs but have been unsuccessful. this is a problem for gm suv's with the 4-speed transmission. the oil consumption issue is way more serious than the transmission problem because many people have been affected more by the oil consumption problem. excessive oil consumption also damages the earth's environment because of the excessive smoke coming from the tailpipes. *tr

Tl* the contact owns a 2007 chevrolet tahoe. while parked, the contact was unable to place the gear shifter into drive. the contact was only able to place the vehicle in reverse. previously, the contact noticed that while accelerating, the rpm reading would increase dramatically. the vehicle was not taken to the dealer for a diagnostic test. the vehicle was not repaired. the vin was not available. the approximate failure mileage was 50,000.

2007 chevrolet tahoe. consumer states several issues with vehicle and request information on recalls, service bulletins, warranties or lemon law *tgw the consumer stated the cruise control down shifted to 2nd while driving at highway speeds and on hills, the starter would hang, there was a noise coming from the ac compressor. the transmission was replaced. however, it continued to hesitate after the vehicle was started, as well as a vibration. there was a clicking noise coming from the differential, the idle needle would rise, while at a stop, the battery drained, the engine stalled, the dash was cracked, there was a problem with the suspension, the tire pressure monitoring system was repaired three times, the passenger side mirror was inoperable, the weather strip had come off the vehicle and there was a clicking noise coming from the u-joint. *jb

2007 tahoe. intermediate steering shaft clunk noise. this noise is a nuisance and doesn't feel safe when driving the vehicle. the problem happens intermediately so it is very difficult to diagnose. gm needs to recall this problem and replace the shaft instead of doing temporary grease jobs. *tr

I was at a stop light, and the problem happened unexpectedly when i pressed on the gas when the light turned green. my car moved forward just slightly, jerked hard to a complete stop, and it wouldn't drive anymore. i was able to get pushed to the side in neutral, but needed a tow to the dealer. the only working gears were r, 3, 2, and 1. bringing it into the dealer, they confirmed there was a problem with the transmission. i had done some research when this happened and noticed that a lot of people had the same problem, all in the same type of scenario where they were at a complete stop. second issue, not nearly as major is the stabilitrak. the light goes on and off constantly, pretty much from the first year i've had the car. and lastly, the interior chrome door handles have all peeled off and cut me and my passengers several times. the exterior door handles have come loose, the fuel pocket is completely broken, and after a heavy rain, water gets trapped inside the shell of the back door and sloshes around while i'm driving. i have to remove the bottom lining of the door for the trapped water to be released. *kb

Front differential started making a very loud noise. it became even louder in 4-wheel drive. while in 4-wheel drive the vehicle didn't feel right. i brought to the dealer who stated water got into the differential, and it had to be rebuilt. this is the 3rd time i have had an issue with the front differential. all 3 times, including this one, was due to the failure of the pinion seal. the first repair on 11/06/09 was covered under gms manufacturers factory warranty. the next 2 repairs, including this one, cost me a total of $1,435.49. i can only wonder how dangerous it was driving around in 4 wheel drive with a differential that was ready to catastrophically fail? *tr

Vehicle will accelerate and max out at fuel cut-off. acceleration is unresponsive to brake application to include 100% application, resulting in smoke and odor. vehicle cannot be stopped other than placing the vehicle into neutral and turning the ignition off. upon restarting the vehicle, rpm will immediately climb to in excess of 5000 rpm. acceleration problems normally occur at higher speeds but have occurred also on city streets. the problem then resets itself at its discretion. cheverolet has been "working" on finding the problem since september, total in excess of 90 days. i was provided with a vehicle data recorder (vdr) to image the issue. vdr has a cable plugged into vehicle computer the dangles between the gas/brake pedal and driver posing an additional hazard. vehicle is an extreme safety hazard likely to result in great bodily injury and/or death. i am unable to and have been unable to enjoy and utilize the vehicle for the purposes to which it was intended for/purchased and have been placed in a severely risky position by chevrolet. in addition, control of the vehicle in inclement weather has been compromised due to failure of the stabilitrac where it engages and disengages without application of the button. this issue has also been raised with chevrolet but no codes were read due to the vehicle being turned off, causing a reset (per chevrolet). however, when stabilitrac problem surfaced yet again, problem was witnessed by chevrolet service rep but no work could be done due to an open ticket with gmc regarding the acceleration issue. chevrolet has downloaded images/information from the vdr and has stated that there is/are issues and reset and returned the vdr to me requesting again that i take more images when my vehicle is stuck in acceleration and to be careful. initial attempt for this repair in september noted "drivable concern." problem is recurring from 0-9 incidents each day. i am concerned for the safety of others as well as myself. *tr

Tl*the contact owns a 2007 chevrolet tahoe. while attempting to place the vehicle into drive, the transmission made a popping noise and the vehicle felt as if it were dragging an object. the contact attempted to park the vehicle, but the transmission would not shift into reverse. he attempted to tow the vehicle in neutral, but the tires would not rotate. the contact was finally able to shift into reverse and the vehicle moved. the vehicle was diagnosed by the dealer, but the failures still persist. the current and failure mileages were 15,287.

We have had several problems with this vehicle. we've had tires replaced twice, rotors, and brakes resurfaced, and rear-end dropped so the springs could be adjusted. but the biggest problem has been with the roaring in the motor. the dealership has had the vehicle for more than 20 days on and off looking for this noise. i've had it to them 8 times or so trying to find it. the noise didn't start until around 3,000 miles, and gets worse and easier to duplicate with more miles. the first 7 visits they said they didn't know what it was and was clueless to it, but the last visit, and 4 days of it, they and gm decided it was a "characteristic" of the vehicle, and nothing could be done. on the otherhand, one mechanic says it's coming from the drivetrain, but others say it's an improper balance in the motor. either way i'm paying too much money for whatever it is! *tr

I purchased a 2007 tahoe in feb. of 2007. i have had numerous problems to date. the first was the a/c blower went out. replaced under warranty. the tire pressure monitor was reversed on the two right side tires. right front was actually the right rear. i have complained to the dealership numerous times about the poor mileage i am getting. 15.1 mpg overall. 60% + of my driving is on the highway. my 2003 tahoe got much better mileage without the so-called "active fuel management system". then at 27,758 miles, the transmission crapped out while pulling into traffic on a busy road. i like the appearance and features of the tahoe, but in my opinion, this vehicle is a disaster mechanically. i have bought nothing but gm products for the last 20 years but will now reconsider. *tr

Truck rolls back when on incline even while in park, and it does not stop, i also noted truck would not go into v$ mode and was shifting a little rough in lower gears. july of 2008 took to bob stall chevrolet for oil change and asked for it to be checked (as well as power system) returned to pick up my vehicle and they insisted tranny was fine as there were no error codes. i mentioned power issue and they claimed to not have time to test (they had the truck all day, it was also not on the roll) unsatisfied i returned again with the truck for another issue (moldings) and asked for it to be tested. received my truck at end of day with moldings fixed but only an assurance my transmission was fine and all was normal, not even mention off battery problem. i returned then a third time to dealer and had to insist they drive the truck and full test transmission. after having my truck a full day i finally was informed that yes my tranny had a problem. their tranny tech drove it and noted the problem in lower gears and after inspection (opened up transmission) discovered burnt bands. my transmission was rebuilt with 2 clutch packs replaced. issue of roll back was claimed to be normal. it took several attempts for this issue to be taken care of and i feel the diversion wa sintentional.. a few more miles.. out of warranty.. poof they would have kindly discovered problem then charged me for it. i have also heard of several others with transmission issues and suspect a design or assembly flaw. *tr

On my new chevy tahoe, 2007, the transmission has slipped several times (50+) over the last 20,000 miles. each occurrence was minor and when mentioned to the dealer at normal service intervals was told was common for a truck (i.e. they are stiff when cold, can do that when you go around a corner, etc.) this finally culminated with complete transmission failure while in traffic. the repair offered by chevy is to just replace the defective part with a like part that the mechanic believes is not different. hence we swapped a failed defective part with the same design that i must assume will fail again! this is not a fix and only delays the inevitable once again. maybe next time it will break when passing or out in the middle of no where? the gear is called a sprag gear and all the gm dealerships are silently aware of the problem. *tr

The transmission went out on my 2007 tahoe ltz with 18,500 miles. i coasted to the side of the road. tahoe would not move in "d", but would in other gears. in "3" i headed to my dealer (about 15 miles away). "3" went out when i had to slow for a light. i then drove in "2" to the dealer. i was told this was the first problem like this they had seen in a 2007. after inspection, i was give technical names of the transmission parts that had torn up inside. i received the tahoe back in 1 week and was provided a free rental car by chevrolet. i have nothing but the highest praise for my dealer, but am extremely disappointed in such a major problem in a new vehicle. i am supposed to receive a full copy of all work done for this repair. *tr

Have an 07 chevrolet tahoe. transmission failed while driving vehicle at 23,000 miles. must be a common problem. friend had same problem this summer at 24,000 miles. many complaints on internet. *tr

I have a 2007 chevrolet tahoe, i was driving up to a red light and stopped completely. when the light turned green i pressed on the accelerator and the my truck made a loud knocking noise and would not go forward. it would go in reverse and a lower gear but not in regular drive. i only have 21,000 miles on it and the transmission has given out. i had it towed to the nearest dealership and they are breaking down the transmission to see what exactly the problem is. *jb

Transmission failure at 25k miles. driving at low speed and turning a corner when i experienced a sharp shutter of the entire vehicle as though i had run over something that did not allow my wheels to turn. transmission could be shifted from park to drive but there were no forward or reverse gears. *tr

1 month after purchase of my 2007 chevy tahoe the service engine light came on. i alerted onstar as i was stranded on the road. onstar indicated through a probe check that my transmission had malfunctioned but the problem would correct itself and the light would go off and i could keep driving the truck. the light went off and i kept driving. some time later onstar was alerted for the same problems, i was told the same as before by onstar. about 1 year after i bought this tahoe i was stranded again around 10:30p.m. along side an unsafe highway with my 3 children. onstar was called and again stated a transmission error that would correct itself and after driving the light should go off. i drove this tahoe home having to pull off the road several times to allow my transmission temperature to cool to prevent further damage. the next morning the light had gone off and i was on my way to take the tahoe to the dealership where it was purchased. 5 miles or so from my home the light comes back on and i alert onstar and was told that i needed to drive the truck to my nearest chevrolet dealership. as i pulled back on the road the transmission stops working immediately as i am sitting in on-comming traffic. i quickly put the truck in reverse as drive will not work any longer to get myself out of harms way. chevrolet was called and transported my truck to their dealership as this was where it was purchased. my truck stayed in the shop three days as they had to rebuild the transmission. i had to pay for a rental with my own money. after picking my truck up from being repaired i was once again stranded along i-95 with my children 2 hours later. as of today my truck is still waiting to be hauled into chevrolet. *jb

Transmission slips. moving from park or reverse to drive - especially in the morning. transmission slips when hard accelerating. taken to dealer twice and they are unable to locate a problem. no computer codes. respond that everything is fine. *jb updated 10/10/07 *tr

My 2007 tahoe has had a transmission/slip/bumping problem and it was first noticed by me about a month after i got it back in april. it has gotten worse the more that i drive it. it has 5900 miles on it and has been to the shop once for the problem. it was not taken care of and now it has been brought to my attention that this is actually a common problem and that it has been made aware of years ago in the older versions. i'm not at all happy about this. *jb

I have a brand new 2007 chevy tahoe, the car was driving normal, i was heading to the on ramp of the freeway, but to get into the freeway i had to make a right and then the on ramp is in front of me. of course you also had cars coming from the right of me. when i saw a gap where i could go, i floored the gas, to go into the freeway, when i heard a loud noise, and all of the sudden the car slowed down. i had to think quick being that the car was an automatic, i shifted to a lower gear, the car started moving but it was making a grinding noise. i finally got out of the way. and i called onstar, my transmission had given. on a 6 month old 2007 tahoe. they took it to the dealer, at the dealership they replaced a gear inside the transmission, to no avail. finally they ended up replacing the whole transmission, because they couldn't figure what was wrong the car. no warning lights or nothing. the guy at the dealership told me, that this was so weird that the techs in michigan wanted the whole transmission shipped to them. they had the suv for a total of 21 days.

Under normal, non-towing driving, the 2007 tahoe (with 27,000 miles) would not go forward when placed into drive. as a result, my family is presently unable to use the vehicle and it was towed to a dealership for repairs. this occurred after the transmission was completely replaced at about 12,000 miles for the same problem. *nm

Transmission drive gears went out would move only in reverse. *nm

I replaced the transmission in my chevy tahoe twice. it is clear that other owners have had the same problems with tahoe transmissions over the past ten years. what does it take for gm to correct the problem??? maybe this site can at least help get the word out about these transmissions. *tr
