2013 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.
2013 GMC Savana 3500 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 label that indicates "CNG Fuel Only" is too small. Owners of affected vehicles will receive replacement labels from General Motors, and dealers can help with installation, free of charge to resolve the concern.
