What 1999 GMC Suburban owners say
Most recent owner complaints, unedited.
The original fuel tank in this vehicle way rusty and leaking. I replaced the original tank with a Dorman model 576-372 fuel tank. The tank was installed in September 2021. The tank began leaking in February 2022. A repair shop discovered that the tank was defective and had failed. The Tank was discarded and replaced with a new unit. As no OEM parts are available the replacement was also and aftermarket part. That tank also was defective and began leaking within 90 days. A third aftermarket tank was installed and it also began leaking recently. When these leaks occur the tank fails in such a way that a large volume of fuel is spilled collects under the vehicle. As there seems to be only one company manufacturing these parts there seems be be a large potential that the issue will affect many vehicles.
The original fuel tank in this vehicle way rusty and leaking. I replaced the original tank with a Dorman model 576-372 fuel tank. This tank included a new fuel pump lock ring, which was used to secure a new fuel pump in the tank prior to installation in the vehicle. The lock rung failed approximately one week after installation allowing the fuel pump to raise up out of the tank. At the next fuel up a large volume of gasoline escaped form the fuel pump opening and spilled. The defective lock ring was replaced with a OEM part and was subsequently discarded.
Gm passlock system faulty leaving me stranded far from home.thankfully, I was not in the road. My vehicle wouldn't start. This is a huge problem and many people have experienced it.
While driving at low speeds or coming to stop the ABS seems to engage and cause erratic stopping and even hard stopping at times. The brake pedal kicks back and is hard to press down and stopping is very difficult.
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.
Complete loss of brakes coming up to a stoplight in moderate traffic. Widespread heavy corrosion/deterioration of brake lines resulted in rupture of brake line over left rear wheel. Emergency/park brake used to avoid accident. Clearly a materials defect in the brake system, in my opinion.
While attempting to stop in a business parking lot, brake pedal unexpectedly went to floor, vehicle ran over curb/stop, damaging suspension. Cause of incident was determined to be a ruptured metal brake line, caused by severe corrosion. A second line was found to have small pin hole, which had not yet ruptured, but could have failed at anytime.
