GMC Sonoma Problems

Fuel Level Sensor Failure

It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.

Check Engine Light Due to Oxygen Sensor Failure

The oxygen sensor can fail causing Check Engine Light illumination and the engine to run rich (burn more fuel than normal).

Power Window Motors May Fail From Overheating

A door window may move slowly or stop in mid travel due to a failing power window motor. The affected window may start working again after the motor cools off. Replacing the faulty window motor will commonly correct this concern.
