 2002 chevrolet impala. the tire pressure light and engine light had to be reset. *dt the consumer stated the check engine light only stayed off for 12 miles the last time it was reset by the dealership. the entire braking system had to be replaced only 2 years after purchasing the vehicle. the rotors cracked on all four wheels. the blinkers would only work if the air conditioner was off and the radio would only work if the blinkers were off and when going up hills. the vehicle would only accelerate to a speed of 10-15 mph. *jb

 2002 impala braking calipers on the back disc on the drivers side holds less than one inch of the disc. transmission rolls in the direction of the slope of the road. *ts the calipers on the rear disc on the driver's side holds less than one inch of the disc. the other three calipers go all the way normally. this has resulted in less braking capacity one one side. the consumer contacted the dealer. since the warranty had expired the consumer would have to pay for repairs. *nm

 After slowing to enter a driveway the car did not respond to gas peddle. it would go very slowly when the accelerator was pushed. it would not correct itself after being stoped and turned off. however after being off sometime it went away and responded as usual. when it was taken to the service dept. it did it again but later the service man said he could not duplicate it, although he knew that it did it originally.

 As of yet there has been no incident however there have been numerous close calls as the transmission is not shifting into gear unless you race the motor. nearly rearending other vehicles, property or pedestrians. i can not safely pull out at an intersection because the transmission may slip. i've read on message boards where hundreds of other people are having the same problem and gm has no good fix for it. it doesn't seem to mater if the car is warm or cold the transmission still acts up. 89k miles on the car when this began and i haven't felt safe driving the car since. thank you *tr

 In january 2006 my 2002 impala loss power. i was going up a very small hill and i didn't think i was going to make it up. i took my car to my local mom and pop's garage and they put it on the computer. it showed that the catalytic converter was bad eventhough the check engine light did not come on. i had them replace not knowing that the car was still under warranty for emissions and they didn't use a gm part. a few months later, the check engine light did come on. again it showed the catalytic converter as the problem. the service technician said he had never had any problems with putting a non-dealer part on a car before but did replace the converter once again with a non-gm part in case the first one happened to be a bad part. a couple of months later the check engine light is back on. took it to the dealership and the catalytic converter shows as well as the transmission. of course, they wouldn't make good on the catalytic converter by this time because it was out of warranty and it wasn't the original gm part. i was told that it would cost $775 just for them to look at the transmission. i cannot afford this and just brought the car home. i'm still driving it but it's worse and worse every day. i wouldn't trust driving this car very far. i've read many complaints on the catalytic converter & the transmission that you would think gm would have to step up and do something. at this point i would never purchase another gm vehicle and my husband is diehard gm. i've taken very good care of this car hoping that it would last until my daughter starts driving and i could hand it trustingly down to her but that's not going to be the case. my husband doesn't take care of his trucks like i would and he still has a 1995 that runs good.

 I purchased my '02 impala through the corporate leasing company of my father's employer. he had no problems with the car other than the transmission fluid turning black by 85,000 miles. when i got the car in june of '05, it was at 121,000 miles, i drove the car around all day, parked the car for 5 minutes, and when i went to start it, nothing happened. the dash lit up, the radio came on, but the car didn't turn over, not even a clicking sound, indicative of a dead battery. i waited 10 minutes, tried again and it started right up. i went for another month without any problems, however in late july, the car failed to start. again i waited 10-15 minutes, and it started right up. this continued sporadically until october 20, when it took 30 minutes of waiting to get it to crank. i took the car to a local gm dealer, who put it on the machine and advised me that the bcm (body control module) had failed and was sending a signal to the passlock system telling it that my keys were incorrect. the service writer informed me that a new bcm installed would run about $500.00, and the service tech advised that this has become a common failure in both the impala and the malibu, which gm has yet to recall. the technician did suggest that a more cost effective option existed with several of the after-market shops, in which a bypass-relay was installed under the dash, to block the erroneous signals from the bcm, which will allow the vehicle to operate normally. the cost for this bypass is about $55.00 and takes approximately an hour to install. the only problem with this solution, is it blocks the key recognition feature of the passlock system, which will make it easier to steal, if someone can start it without damaging the key ignition. i think it is necessary for gm to understand that a vehicle's failure to start due to faulty component in the anti-theft system is a very serious concern which needs to addressed. *nm

 I have a 2002 chevrolet impala. it has around 53,000 miles on it. my wife drives the car and it has been driven slowly. about 3 weeks ago she told me the car shifted hard and i drove it and found that problem also. that went away for 2 weeks and it happened again. we were referred to a independent transmission shop and we were told that the transmission in the impala has been having problems and we were told it needed to be rebuilt. i then took the car to the chevy dealer and they said they is some problems but just wouldnt get specific with me. i then went to another independent transmission shop and was told the same thing as the first shop told me and that was i needed this rebuilt. they said the transmission is a bad design and want $2400. to $2600. to fix it. this is the same price as the first place gave me. i think if this is so common of a problem g.m. should do something about it. i am going back to the chevy dealer and am going to ask them just what they can do for me. i'm not a happy person, this car has not been driven hard and infact it's been treated nicely. i can't find a recall on it but it seems like there should be one in effect for it. i also think this problem could be a serious road hassard if the transmission goes out while being driven.

 1. within this past month, am noticing tremendous power loss and shifting/timing issues with the transmisson when accelerating to higher gear.. potential consequence would be insufficient power to accelerate out of the way of oncoming traffic.*ak 3. have investigated and seen numerous complaints online concerning a shift solenoid that is a very troublesome issue with a lot of gm owners. typical parts cost and labor for this problem runs in the $400.00 ballpark.

 Car rolls backward on an incline. i.e. at a stop light. must use both feet (1 on the gas and 1 on the brake) to keep the car from rolling into the car behind when i am on a steep incline. i have documents from the dealer stating this is normal. this is the first automatic transmission i have ever owned that rolled backward without stopping after a few inches. this is an unresolved problem and not just an incident. february 1 2002 is just a start date you can truthfully say that i have several incidents every day because this transmision will do this on every incline. *ak

 I noticed that my transmission shifts very hard when it warms up. i took to chevrolet dealer, they changed my transmission mounts, and dog bones. i paid quite a few dollars and my vehicle still has this same problem. the vehicle has 85,000 miles, but i,ve maintained the vehicle very well. i,ve also had problems with my steering play.the dealer changed some parts in the assembly which is better. i'm a mechanic and i don't beleive that there was anything wrong with my drivetrain mounts, but it's in the transmission. i paid alot of money and still have the same problem. since owning the car i had problems with the drivers window. the motor was changed once under warranty now it's doing the same thing again. the problem is it will go down but won't go up sometimes. *ak
POWER TRAIN - AXLE HUBS
11/18/2004111/13/2001
 Both left and right hub bearing assembly have been diagnosed as loose. an independent repair shop advised that both need to be replaced before an alignment could be performed. john wigant of walker chevrolet told me, prior to a written statement, that both sides exhibit a worn out diagnosis, but that only one side should be replaced now and that the other might never need to be replaced or it could get worse. in a written statement from john wigant of walker chevrolet, i was informed that only the passenger side bearing should be replaced. i have had other problems with rotors that literally shook my front end and steering column during the warranty period of 36,000 miles. and the intermediate shaft has been repaired and replaced 3 times. the last time it was reported on november 18, '04 and not repaired until december 30, '04 at 53,267 miles. i have been advised that replacing these hub bearings will cost me about $1,000.00 to repair. i have read another complaint in nhtsa files that a same year impala front wheel or axle fell off and caused a driver to veer off the road. i feel that the past rotor and intermediate shaft problems have exasperated this wear and caused it to be a bigger problem. i have had problems with the electrical system, speedometer cable, radio, and rear window. all have been serviced, but continue to exhibit the same problems that existed before repair or replacement. *jb

 The intermediate drive shaft needs to be replaced. it stated making noises when the steering wheel was turned. took for service the part was ordered on nov 3 2004. part still has not came in. called the chevy dealer. seems like its been a common problem. and takes about 2 months to get the part. i was told only 6,000 are made a week and they started in the hole 100,000 and the problem is getting worse. if that many people are having the same problem, why are they not recalling the part. i asked the man if my car is safe to drive he said isn't is under warranty. i said no and all of a sudden the car was safe to drive. it does not feel safe and i am not at all confident about driving and i think chevy should admit they have a problem. *jb
