Streering began to act eratically and felt as if I hit a patch of ice with a rapid release of turning force while making a right hand turn. On the first occasion when this occurred I was exiting a freeway cloverleaf in wet conditions and the eratic movement caused the rear of the truck to lose traction and a near loss of control. I was able to recover the the slide without an accident but found it to be an unnerving event. After researching auto forums on the web I have found numerous postings on this subject and it is related to a failure of the steering wheel sensor located at on near the base of the steering column in the passenger compartment. I replaced this sensor on 05-04-05 and the condition is now corrected. I purchased the GM part #26064468 at a dealer and did the labor myself. This is an extremely hazardous defect which will inevitable cause a serious accident, especially in adverse weather conditions.
