2011 GMC Savana 1500 Problems

One or More Rear Lights May Not Work

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.

Check Engine Light and Trouble Filling Gas Tank

The GMC Savanah 1500 is known to have issues with the EVAP system, a part of your emission control system.

The EVAP canister vent valve or valve solenoid wiring may fail causing illumination of the check engine light, setting code P0446, and problems filling the tank with fuel.

To correct the issue, the EVAP canister vent valve, solenoid, and wiring must be inspected. The most common fix is replacement of the wiring connector or replacement of the vent valve assembly.

Reduced Power and Check Engine Light

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 Recalls

Natural 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.

Insufficient 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.

Possible Brake Fluid Leak From Rear Brake Hose

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.
