I purchased this vehicle used, have had an ongoing problem with the "stabilitrak service" light coming on, have had it into the shop "autotire" for service 2 times, they have replaced the "steering wheel motion sensor" and had the "angle sensor" neither have fixed the problem. while there is no recall for this there should be, sounds like a design flaw with no apparent solution, the "service stabilitrak" light comes on all the time, no matter if van is setting still, driving, even in park. i am not real sure who to contact with something like this without being charged hundreds if not thousands of dollars, have already had downtime and aprox $500 in cost already. this is something the gm should find the fix and recall, i see there are many vehicles and many years involved. we use this for our company and time is money. the date listed below is the 1st time i took in for service.
