- Summary
- On certain pickup trucks equipped with an 8.1L V8 engine, the crankshaft position can operate intermittently or fail completely. If the sensor operates intermittently, the ses light may illuminate and the vehicle may run rough. The engine may stall, and if so, may re-start immediately or after a cool down period.
- Consequence
- If the sensor becomes completely inoperative, the engine will quit running and will not re-start. Either of these failures can increase the risk of a crash.
- Remedy
- Dealers will replace the crankshaft position sensor free of charge. The recall began on December 18, 2007. Owners may contact Chevrolet at 1-800-630-2438 and GMC at 1-866-996-9463.

Has your Chevrolet been repaired?
Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.
NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Chevrolet dealer can also check your VIN. Recall repairs are free.
