MAKE/MODELS: MODEL/BUILD YEARS:

Chevrolet/Silverado 2001

Chevrolet/Suburban 2001

GMC/Sierra 2001

GMC/Yukon 2001

MANUFACTURER: General Motors Corp.

NHTSA CAMPAIGN ID NUMBER: 07V521000

MFR'S REPORT DATE: November 07, 2007

COMPONENT: Engine and Engine Cooling

POTENTIAL NUMBER OF UNITS AFFECTED: 11974

SUMMARY:
On certain pickup trucks equipped with an 8.1L V8 engine, the crankshaft position sensor 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 is expected to begin during December 2007. Owners may contact Chevrolet at 1-800-630-2438 and GMC at 1-866-996-9463.

GM recall No. 06083. Customers may also contact The National Highway Traffic Safety Administration's Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to http://www.safercar.gov.
