GMC Yukon Hybrid ProblemsReduced Power and Check Engine Light
The throttle position sensor (TPS) on the GMC Yukon Hybrid and GMC Yukon Denali Hybrid is notorious for failure which causes:
- Check engine light
- Reduced Power message
- OBD trouble code P2135
This issue is related to the throttle position sensor on the gasoline engine, and can be caused by faulty wiring to the TPS, bad connection at the TPS, or a failed TPS. Note, this does not affect the hybrid drive system.
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.
A Loose or worn gas cap may cause 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.

GMC Yukon Hybrid RecallsEngine Stalls From Electrical Module Short
The chassis electrical module can short due to internal contamination. This can result in the vehicle stalling. Dealers will replace the chassis electronic module free of charge to resolve the concern.
All late model vehicles are equipped with a "Shift interlock" system that prevents vehicles with and automatic transmission from being shifted out of the Park position under certain conditions. Some of these vehicles are being recalled because they may have been assembled with a broken park lock cable or a malformed steering column lock actuator gear. Failure of these components can allow the shifter to be moved out of the Park position with the ignition key removed or in the off position. This can cause the vehicle to roll away unexpectedly increasing the risk of injury or a crash. Dealers will inspect the recalled vehicles and replace the steering column as necessary.
The rear axle cross pin may break. The cross pin is an internal component of the rear differential, which is housed in the rear axle assembly. If the cross pin breaks, the rear axle may lock, which could result in loss of control and a crash. Dealers will install a new rear axle cross pin to correct this concern. This recall should begin no later than January 25, 2011. The General Motors number for this recall is 10426A.
