Cadillac Escalade Hybrid ProblemsReduced Power and Check Engine Light
The throttle position sensor (TPS) on the Cadillac Escalade 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.

Cadillac Escalade Hybrid RecallsThe Rear Axle May Fail (Recall Expanded)
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.
The heated washer module under the hood could overheat due to excessive current draw. Under certain conditions, this could result in an under hood fire. This previous recall attempt in 2008 to repair this concern did not have the expected success. Dealers will now permanently disable and remove the heated washer module to correct this concern. This recall is expected to begin on June 20, 2010.
The RTV seal on the fuel system control modules may allow water to enter into the module. Water in the module can cause a short, which may cause hard starting, a crank-no start condition, or stalling, and the Service Engine Soon light may come on. If the engine stalls unexpectedly, there is an increased risk of a crash. Dealers will replace the fuel system control module free of charge. The recall began on May 18, 2009. The GM recall number is 08411.
