| 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. | |||

| 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 | |||

| Continuation of same problem after eight (8) documented repairs by chevrolet motor division. this last incident resulted in a non-0injury collision, where my vehicle sustained damage. see previous complaint: odi 10253010 vehicle maintains and increases in acceleration with no application to the gas pedal. chevrolet motor divisions attempts/repairs: cropper | |||

| 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 | |||

| 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. | |||

| 2007 chevrolet 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. | |||

| 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 | |||

| 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 | |||

| 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 | |||

| 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 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 | |||

| 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 | |||

| 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 | |||
