2010 GMC Savana 3500 ProblemsReduced Power and Check Engine Light
The GMC Savana 3500 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.

2010 GMC Savana 3500 RecallsInsufficient Instrument Panel Padding
Certain vehicles are being recalled because if a crash were to occur not requiring deployment of the front airbags, the head of an unbelted front seat passenger could hit the instrument panel, resulting in personal injury because the panel may not sufficiently absorb the impact. As of this writing, General Motors is still working on a remedy for this concern.
A short circuit may develop in the voltage regulator, internal to the alternator. This could cause the alternator to overheat to the point of causing a fire. Dealers will inspect and replace the affected alternators as necessary. This recall is scheduled to begin by April 12, 2010. The General Motors recall number is 10216.
The heating and AC control knobs may fracture and spin on the control shafts. The driver may not be able to control the heating and ventilation for the vehicle. If this happens when the defrost system is needed, visibility could be reduced, which could lead to a crash. Dealers will replace all of the heating and AC control knobs free of charge. The recall began March 11, 2010. The GM recall number is 10012.
