Filed Jun 7, 2022 · Fuel system · IA

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.

Engine RPM increases when foot is off the accelerator while driving. This issue started approximately 4 months ago and is on going, each time the vehicle is driven. This is unintended acceleration.

Fuel pump/connector failure. Initially engine would shut down intermittently. On last occasion, vehicle engine shut down resulting in loss of power steering, power brakes, etc. Would not restart. Former gm mechanic told me that he witnessed this problem numerous times and found most cases involved failure of electrical connector or ground connection at fuel pump.

Dt: the consumer stated that while driving with a quarter tank of gas the vehicle stalled without any previous warning. Then, it completely died. The consumer pushed the vehicle to the side of the road. The consumer was finally able to restart the vehicle after several attempts, and drive home. The next day he inspected the connection to the fuel pump. He discovered there was low voltage to the electrical assembly area. The federal safety agency recall campaign 05v155000 was issued involving the same type of vehicle. This vehicle was not included in the recall due to the VIN, but was experiencing the same problem as indicated in the recall. The consumer called gm ,who suggested a diagnostic test. No repairs have been made due to the expense of the repairs. *ak (11/22/05) *sc updated 01/10/07.

Door acuators faulty. Power steering pump replaced. Fuel guage faulty. Security system overrides starter which does not allow the vehicle to be started. We have had the vehicle "serviced" three times for "door actuators" as we were told this is what was causing security system to shut down vehicle. This did not solve the problem. Gmc national service center was not helpful. They did not return calls or set-up special service appointment at local dealer as they promised. There are several incident dates of when we could not start our vehicle. Will use july 29th as one date, unable to start vehicle while on summer vacation in lake tahoe area. If this happens during real emergency it would be unfortunate.
