2011 GMC Savana 1500 ProblemsReduced Power and Check Engine Light
The 2008-2014 GMC Savana 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.
2011 GMC Savana 1500 RecallsNatural Gas Leak
Certain vehicles equipped to run on compressed natural gas are being recalled because the high pressure natural gas regulator could develop a leak, increasing the risk of a fire or explosion. Dealers will replace the natural gas regulator to correct this concern.
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.
The right rear brake hose may contact the tire or wheel rim, which can cause a hole to be worn into the brake hose. This may result in fluid loss, which would reduce the effectiveness of the rear brakes and increase the risk of a crash. Dealers will secure the right rear brake hose to ensure sufficient clearance. This recall is expected to begin by May 13, 2011. The General Motors recall number is 11126.
