 The traction system was activating for no reason. service abs light came on in vehicle. dealer replaced left wheel hub, including sensor. problem recurred the day after and the wrong assembly was installed, the correct assembly was installed. one month later problem recurred. dealer claimed it was a loose connection on wheel hub assembly. seven months later problem recurred. dealer now says the right hub assembly needed replacing, as well as the transmission solenoid. repairs have not been done for the latter because we want dealership to repair free of charge.*ak

 My vehicle has a problem with the transmission running rough, nearly stalling, and a 0742 code being activated. the car has 123,000 miles on it, so it is well out of warranty. a local transmission shop stated that the transmission needed to be rebuilt and quoted a price of $1400 to rebuild the transmission. i know that the car has a great deal of mileage on it, but i expect a little bit more for the money i paid for the car. after looking on this web site at the number of complaints and problems people are having with this car/transmission, and seeing that the 4t65e transmission is used in over 20 gm cars, when are you going to do something about gm taking advantage of this before it costs the american public thousands of dollars? anything you can do to push gm to make this problem right would be appreciated. if you cannot the only thing i will do is buy japanese.*jb

 Power train failure: first sign of problem was harsh shifting, had the transmission fluid and filter changed, still had same problem. before i found the service bulletins on this problem the planetary gears got chewed up by a broken piece of metal, had to rebuild the transmission $1800. filed complaint with gm, since i did not have it repaired at a dealer (for twice the price) they would not help. now i have a 2001 monte carlo showing the same harsh shifting. the transmission has be flushed by the dealer and they put an additive into the transmission fluid to help the sticky value problem, did not work. there is a pattern here and gm will not stand behind their product. *nm

 Transmission failure--2001 chevy impala with 45,000 miles--basically no advance notice--stopped at a traffic light, depressed accelerator and transmission took awhile to engage before moving forward. happened again at the next two (2) lights. got car home intending to take to dealer in morning. backed car out of garage--went 5 ft and it would not move further. pulled forward and able to put in reverse to back out of driveway. managed to get to dealer. going to teardown transmission tomorrow. should not happen on a vehicle with 45,000 miles---90,000 maybe, 45,000 no. this is my 3rd transmission failure with a gm product since 1980. like their styling but don't know if i can continue to purchase their products.*ak

 My husband said that his car was driving poorly for about a month or so before it broke down on a busy road. since this is the third chevrolet transmission to break down on both my husband and i we knew that was the problem. as a result we were without a car for about a week. luckily there was no accident but there very well could have been. the car just died at a red light. chevrolet replaced this transmission with a rebuilt transmission,because it was still under the original factory warranty. the warranty on the rebuilt part was for only 90 days. last year when we had to pay for the transmission to be replaced on my 1997 venture after only 52,000 miles the warranty given was for one year. *ak

 I currently own a 2001 chevrolet impala ls, 3.8l v6. before 36,000 miles i took my car to the dealership. the vehicle was running poorly and when it was cold the transmission would slam into gear. dealer made some repairs and told me the fuel system needed to be serviced. i declined the fuel service at the time and the transmission slamming into gear from a cold start continued. the problem worsened at 47,000 miles. i took the car back to the dealer and after 2 days i was told that the problem was the fuel system service. at 50,000 miles the transmission began slipping severely. i tried to get the car home and it failed to engage while pulling into traffic. i got the car home to perform the 50,000 mile service to the transmission and found a handful of metal in the pan. had the car towed to the dealership and found out that the transmission was completely totalled. gm only offered to pay for half the repair costs. there is no recommended service before 50,000 miles and i don't feel i should be responsible for the repairs on this vehicle. i have owned it less than 3 years. *ak

 While accelerating from a stop sign, car shook all over and i heard a loud bang. the car would not move at all. i coasted to the edge of the road where i waited for a tow truck. the dealerships service manager informed me after about a week, that my planetary gear had exploded. he also stated that the fluid filter was full of metal shavings. he stated to us that there was nothing that i could have done to prevent this from happening. my new transmission cost me $2200. this car has just 55000 miles on it. it is absolutely insane that i am paying all of this money to repair this car, that is practically new. i have contacted gm's corporate customer service people and they will offer no assistance in this matter. the service i received from them was poor. the case was actually lost once therefore i had to start all over again. the woman who then took over the case bold face lied to my fiance and then back pedaled by saying that there was another case just like mine and the woman just happened to have the same name as me. what a coincidence. in addition to this, just 10 days prior to the transmission's death, i had to replace a catalytic converter in the vehicle. *ak

 I have a chevrolet impala 2001. just last week the transmission completely went. i just received word from the transmission shop i took it to. the estimate is $1700.00. which is ridiculous for a car with 38,500 miles. gm stated that since it is over warranty there is nothing they could do. second they stated that the impala would need to be at a gm dealer for them to even open a complaint with the issue. why would i take it to a gm dealer to have them tell me sorry out of warranty and then charge me double the quote of a transmission shop. fool me once shame on you. but fool me twice shame on me. any advise you could offer would be appreciated.*ak

 We heard a low rumbling noise while accelerating from a stop, we barely made it through the next major intersection as the car was hardly moving forward any more and coasted to a boulevard off of a major road. the car jumped forward in park when we restarted it and then it would not respond whether we tried to put the car in drive or reverse. this is a 2001 vehicle now in need of a refabbed transmission for a whopping $2700! the dealer never opened the transmission to find out exactly what went wrong (they guess it's the gear set) and they refuse to let us get a 3rd party to examine it. they will charge us a $700 non-refundable core fee even if we return the core to them in a timely manner. also, the time table for them to return the part to gm just went to 24 hours. originally they said it usually takes around a week for them to send the part back!*ak
