| Premature total transmission failure at 60,667 miles due to faulty design of sun gear hub assembly. the shaft collar broke off without warning causing transmission to fail. the replacement part from gm has the collar to hub mating strengthened from the factory original, so it is known in gm this part has a design flaw from the factory. i was and am unemployed and this was a terrible financial burden at a bad time. contacting gm was no help - it is out of warranty. further complaints to better business bureau auto line returned same answer - out of warranty. this vehicle has been babied and well cared for. no trailers have been towed and no off-road use. ridiculous a $41,000 vehicle has this problem at only 60,000 miles. i have also talked to 3 other suburban owners in my small town and all have experienced the same problem. can't someone force gm to take responsibility for their failure> i warn people about purchasing suburban's now without an extended warranty. *jb | |||

| Have owned '90gmc c1500 p/u & '99 gmc c1500 suburban in past 12 years; both vehicles have had same problems w/ front brake pull/wear; suspension; brake pipes; engine/trans. hesitation, hang....; corroded + battery cables, batteries; leaking hvac ducts; and on & on. how in the world does 12+/- years of documented brake problems across vehicle lines/models not warrant a massive recall and/or compensation to owners for obviously faulty engineering, materials, etc.....????!!!! i suppose the ford/firestone problems took precedence? can you say class action??*ak | |||

| Vehicle was moving on the interstate while at 65 mph on cruise control. the automatic gear shift column was struck by the passenger and the transmission was sent into reverse. this action caused the brakes to lockup and the control mechanical lock on the wheel column was locked into a right hand turn with no way to control the vehicle. the vehilce started to skid out of control and then proceeded to roll over three times. all occupants were in saftey belts except my daughter who was int the back seat asleep. the vehicle was totally destroyed. it took resecue crews to remove myself the driver and daughter who was trapped in the back. we were transported via ambulance to a local hospital. all five passengers were released with only minor bruises and cuts. i would like to find out why the steering column lock and why a safety feature is not provided to keep the transmission from being accidently put into reverse while the vehicle is traveling in drive. please help me find a solution to this potential problem. *ak | |||

| The driver's side front axle shaft seal on the differential leaks fluid, which runs onto the hot exhaust pipe which produces a smell and a possible fire hazard i bought this 1999 gmc suburban vehicle used at crown motors in charlevoix michigan on 02/02/01, with 21904 miles on it. about 6 months after i bought the suburban i started smelling a burnt oil odor when i would get out of the vehicle after driving the vehicle. i couldn't figure out what the odor was. about a year ago i had my suburban serviced and was told that the front drivers side differential seal was leaking. this was told to me as a quite common problem with this type vehicle. i went to crown motors and told them about the problem. i was referred to the service manager who said that he would not do anything about the problem because the vehicle had almost 70,000 miles on it. this is my third gmc suburban and i have always been satisfied with the way that they last. i believe that if gmc has a problem and possible fire hazard with these newer vehicles that they should have a recall on them and get the problem fixed before a fire starts and some innocent person gets trapped and killed by their problem. i am not sure of the date that i contacted the service manager at crown motors or the exact date that the leak was found but i am using today as the incident date. thank you. hope you can do something before some gets killed or injured by a fire. *jb | |||
