2013 GMC Sierra 1500 Problems
RepairPal has identified the most common problems with the 2013 GMC Sierra 1500 based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The GMC Sierra 1500 uses a throttle position sensor (TPS) which commonly fails and causes:
- Check engine light illumination
- Reduced Power message
- OBD trouble code P2135
This issue is related to the throttle position sensor, and can be caused by faulty wiring to the TPS, bad connection at the TPS, or a failed TPS.
To correct this issue, the wiring harness, connector, and throttle position sensor must be inspected, tested, and/or replaced. The most common cause is a faulty TPS.
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.
The steering may develop a clunk type noise from the upper intermediate steering shaft. Our technicians tell us that you should check with you local GM dealer to find out what the latest repair is for this condition.
