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.
Vehicles Involved
For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address
information has been prepared and will be provided through the applicable system listed below. Dealers will not have a report available if they have no
involved vehicles currently assigned.
-- US dealers - GM DealerWorld Recall Information
-- Canadian dealers - GMinfoNet Recall Reports
The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration
data for any purpose other than follow-up necessary to complete this program is a violation of law in several states/provinces/countries. Accordingly, you
