| Tl*the contact owns a 2001 chevrolet suburban. while driving 35 mph in the rain, the abs light illuminated. when the contact turned off the engine, it made a humming sound. he disconnected the module and the humming stopped. the contact took the vehicle to the dealer the following day and they replaced the module under warranty. three years later, the failure recurred. he purchased the third module and had it replaced by a local mechanic. three weeks ago, the contact noticed that the turn signals on his vehicle were intermittently illuminating. as of june 12, 2008, the vehicle has not been repaired. the failure mileage was 60,000 and current mileage was 80,000. updated 07/08/08. *bf the consumer also stated there was a delayed engagement from reverse to drive. updated | |||

| I purchased a 2001 chevrolet suburban in late 2005. we are currently on our third transmission with this vehicle. the first one locked up at 20 m miles and was replaced under warranty. the second failed at about 98 m and cost us about $2500 to replace as gm only offered a 1 yr. warranty on replacement transmissions at that time. i'm already concerned about the third transmission as it occasionally has trouble dropping into first upon stopping. i think gm has a problem here that they are failing to own up to. my only consolation is this transmission has a three year warranty.*jb | |||

| Transmission failures in 1999 through 2002 chevrolet tahoe's, suburbans, and k1500 trucks. i have owned several chevrolet vehicles. in my small circle of acquaintances, i have experienced what i believe to be too many transmission failures by the afore mentioned vehicles. my brother in law just had to have his k1500 transmission changed out. my brothers son had to have his 2001 k1500 transmission changed out at 60000 miles. my brother has had two transmissions changed out in his 2002 tahoe. and finally, today january 26, 2006, my wifes transmission in her 2001 suburban with only 78000, never used to tow anything but a lawn mower trailer, just went out with several school kids on board on a very busy road with no shoulders. this could have turned into a bad situation. what is the deal? *ak | |||

| Purchased 2001 chevrolet suburban at the end of august, drove it for 1600 miles and the transmission went out. according to the mechanic, the transmission completely came apart inside. this bothered me because of the position of the transmission and my children in the vehicle, and the possibility of shrapnel coming out of the transmission. this, of course, did not happen but the dealership is refusing to take any responsibility and i have not heard from general motors. the vehicle is less than three years old and has 48000 miles on it.*ak | |||

| When the vehicle has warmed up and i am driving between 10 and 30 mph transmission seems to slip between 1st and 2nd gears. while slowing down to make a turn transmission doesn't know what to do. it can't decide to stay in the present gear or shift down to accomadate the lower speed. therefore, it takes about 10 seconds for the transmission to finally find a gear so i can proceed. also, when coming to a stop, the transmission takes about 10-15 seconds to shift into 1st, if i want to go immediately after stopping, the transmission is still trying to downshift and the engine races until the transmission finally catches up. again, the dealer found no problem with the vehicle/transmission. *ak | |||

| My 2001 chevrolet suburban got in an accident due to parking pawl failure while parked on a sloped surface. parking pawl is a transmission gear safety locking mechanism that will prevent a vehicle from moving while in park position. i contacted general motors product allegation department to inform about this serious defect. general motors assigned an investigator to gather details and information the investigator submitted all the information and details of the accident to a general motors engineers who will review the cause of the failure of the parking pawl. initial finding by gm authorized service repair shop, the cause of the failure was the premature wearing of the parking pawl mechanism. from a design standpoint this parking pawl mechanism by no means should not be subjected to any premature wearing. otherwise, this is a serious and dangerous design error. after several months of review and investigations, gm said they found that it was material defect. the big question now is how many 2001 chevy suburban was affected by this material defect. also, gm representative was reluctant to provide me a copy of the investigation results conducted by their design engineers. the parking pawl mechanism failure cannot be detected easily by an average person, unless a thorough investigation will be conducted or an accident will occurred. also, my 2001 chevrolet suburban was discovered by gm authorized service shop that the emergency parking brake was having a premature wearing on the brake pads. this really a very serious and dangerous case for all 2001 chevrolet suburban for having a potential emergency brake pad and parking pawl mechanism defect. i am highly suggesting this office to conduct an investigation to avoid a similar fate with firestone case. because i suspect gm is covering up this defect to avoid massive recalls on all 2001 chevrolet suburban. *jb | |||

| I would like to request your agency to conduct a thorough investigation about a defective parking pawl on a 2001 chevy suburban, this parking pawl mechanism supposed to lock the transmission gear to prevent a vehicle to roll or moved while on park position, especially on a rolling hills or sloped parking lot. i am sharing this information for the safety of the general public and consumers who owned a 2001 chevy suburban, because the vehicle has the tendency to moved while on parked position on a rolling hills or sloped parking lot. this problem cannot be detected easily by an average person. the vehicle need to be inspected at the dealership service shop and have it check for a sign of a worn out of the parking pawl mechanism. this information will benefit current owners of 2001 chevy suburban that gm is not more than willing to pay any out of pocket expenses will incurred in case of an accident. unless someone will get seriously injured as case may be. this input was on based on the accident happened on my 2001 chevy suburban last june 20,2002. the body repair cost of my 2001 chevy suburban was $4000 plus. | |||

| Our 4 year old child was able to put our 2001 chevy suburban in gear without starting the car or pressing his foot on the brake. the car starting rolling down the hill. fortunately my wife was able to jump in the window and press the brake to stop the car. we were very lucky that none of the children in the area were hurt and that no property was damaged other than a small piece of fence. apparently with the key in the ignition and in the first accessory position you are able to take the car out of park without depressing the brake pedal. i tried this on several other chevy models that have the gear shift on the column and you are able to do the same thing. i called chevy and the dealer and they both said that this should not happen and to bring it in for repair. the dealer even went to the lot and did what i described on a 2006 suburban and agreed that it did happen when he did it. if this in fact the way the car is manufactured it would be nice if they acknowledged that fact and put it in the owners manual. *tr updated 12/12/2007 *bf the consumer stated the manufacturer is being phased out, however would like to be notified if the older owners would be notified. updated 12/12/07 *tr | |||

| Oil consumption, steering column, side door panels, rear-end, seats cracking, front popping noise, steers to right constantly. this has been an ongoing thing since we bought the vehicle new in 2001. we have complained to the consumer reporting agency here in n.c. and also talked to the dealer and manufacture on numerous occasions. dealer said they have had several vehicles with oil consumption that they have traded because of it and they just kept telling us it is within manufacture limits. they have tried to fix the oil problem but with no success. also the steering has been broken down twice because of its problem. the door panels are still not fixed after 2 tries. the rear-end has been worked on 2 times because of differential fluid, the steering wheel still scrubs when turning to the right and the driver's seat is starting to crack. the consumer people in raleigh will not help us after we filled the complaint, they wrote us and told us to hire a lawyer and the manufacture only offered us a $1000.00 owner/loyalty certificate towards a new vehicle. what is our next step without hiring an attorney? *jb | |||

| I see where chevrolet is recalling the surburban for a defective driveshaft. i have an early 2001 model and my driveshaft did cracked. i was stuck in san diego for two days for the dealer to get the new part. i was told by the service manager that this was very rare, thus hard to find the part. the mechanic told me that they could not find the part because this was so common and the other dealerships did not want to give up the part. first i am mad that i was lied to by the service manager, but i also wonder if the drive shaft probem is prevelent in the 2001 suburban model as well. i would be interested in your research.*ak | |||
