“My 1999 c1500 Suburban caught fire while parked and completely off. It had been parked fro 9 hours when we were awakened at 2am by neighbors and police trying to evacuate our home. The car burned to the ground and was the most frightening experience. I have a 9 and 6 year old that are traumatized by the incident. I reported the matter to the Gmc customer care and they replied saying that they would contact me in 2 days. This is unforgiveable.”
NHTSA complaint #10818727, filed 2016-01, 229,000 miles“Upon purchase of my vehicle the brakes have not worked properly ie very bad chatter, poor stoping distance, warped rotors. I complained numerous times to no avail and they had tried (so they say) to fix the problem but it is never right. If you pull a small trailer you have to be very cautious of your following distance as you will not be able to stop in time. I have even spoken to many dealerships and finally one in hudsonville mi. Admitted they were under engineered for the weight and size of the vehicle. …”
NHTSA complaint #10119431, filed 2005-05, 30,000 miles“While in operation, for no reason, engine stopped running, loosing steering and braking. Took to private auto repair shop and they could not find anything wrong. Took to the dealer and they cannot do anything unless it happens again and I have it towed in. I called Gmc and they cannot do anything unless it happens again and I have it towed to the dealer. It is too dangerious to drive with this problem. This has happened twice to my brother in-laws 1999 chevy Suburban and both times it was taken to the dealer. They replaced the altenator the first time and the battery the second time. …”
NHTSA complaint #10039373, filed 2003-09, 74,350 miles“Owner was hearing noises from the driver side of the vehicle. Owner took the vehicle to the dealer and discovered that the transmission was not bolted to the engine. Provide further details.”
NHTSA complaint #10065554, filed 2004-04, 90,000 miles“The issue I want to discuss concerns the placement of the gas tank on suburbans. The Suburban my wife purchased did not have a trailer hitch. At the time of purchase I owned a 86 vw scirroco. I noticed without a trailer hitch on the Suburban the 43 gallon was very exposed. In fact my vw would go under the bumber and hit the gas before hitting anything else on the Suburban. This has to be dangerous!!. I bought a class iii trailer hitched and installed it soon after purchase of the vehicle. Most suburbans have trailer hitches but for the ones that don't is this a problem???”
