Common GMC Sierra Problems

Some customers have reported these issues, which are among the most common ones they’ve had with their Sierra.

Faulty Speedometer Readings

The speedometer in some GMC Sierras, especially the 2005 model year, has been known to fail. Unfortunately, the most common form of this issue is not only that the speedometer ceases to function; rather, it is that the speedometer no longer provides an accurate reading. That could lead to dangerous speeding or losing control on a curve.

Faulty Fuel-Level Sensor

A fuel level sensor communicates with the engine computer to provide information. Due to not knowing the precise amount of gas present at all times, problems such as stalling and running out of gas while driving can arise if this sensor fails.

Electrical Problems

Unfortunately, the Sierra’s electrical problems aren’t limited to the speedometer. The GMC Sierra also frequently experiences faults such as malfunctioning dashboard gauges, burned-out inside lighting, and unpredictable locking and unlocking.

Issues with the Heater

This may be just another electrical problem, but it deserves reporting nonetheless. The Sierra’s heater can be switched on at any time, even in the middle of summer.

Engine Knocking

Most auto enthusiasts will agree that engine knocks are a much more significant issue. Unfortunately, internal engine knocks can be just as challenging to diagnose, and both the diagnosis and the repair can be costly.
