The problem
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.
The risk
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.
The fix
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.
