2010 GMC Savana 2500 Problems
RepairPal has identified the most common problems with the 2010 GMC Savana 2500 based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The 2008-2015 GMC Savana 2500 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.
The tail light wiring harness in the cargo area is not protected very well. As a result it may become damaged due to normal wear a tear. This damage can causing some or all of the rear lights to stop working.
A loose or worn gas cap could be cause the Check Engine Light to illuminate.
The spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time.
The fuel pump may fail causing the engine to stall and not restart.
