*****THIS PROGRAM IS IN EFFECT UNTIL OCTOBER 31, 2008*******
Condition
Certain 2008 model year HUMMER H3 vehicles may have a brake control sensor that is out of position. If the sensor is out of position, the StabiliTrak System will be inoperative and there may be an unwanted traction control system (TCS) activation during vehicle acceleration. During an unwanted TCS activation, the TCS lamp in the instrument panel will flash and the vehicle will have reduced power for up to 5 seconds, depending on the type of acceleration. Afier 5 seconds, the TCS will turn off and normal acceleration will resume; however, the condition may occur again after a brief period of normal acceleration. The driver can turn the TCS off to eliminate this condition.
Correction
Dealers are to inspect, and if necessary, reposition the brake control (yaw rate) sensor.

Courtesy Transportation
The General Motors Courtesy Transportation program is intended to minimize customer inconvenience when a vehicle requires a repair that is covered by the New Vehicle Limited Warranty. The availability of courtesy transportation to customers whose vehicles are within the warranty coverage period and involved in a product program is very important in maintaining customer satisfaction. Dealers are to ensure that these customers understand that shuttle service or some other form of courtesy transportation is available and will be provided at no charge. Dealers should refer to the General Motors Service Policies and Procedures Manual for Courtesy Transportation guidelines.
