We keep getting a message stabilitrak off, service stabilitrak then low engine power and I can't go above 40mph. Sometimes it clears after I turn off the vehicle and sometimes I can't drive it for a day. It seems to happen when it is wet outside or a couple of hours after I get it washed. This has happened after short drives, as well as after driving for two hours and exiting the expressway and it happens then. I have had in the GM shop two times and it still isn't fixed

I AM HAVING THE SAME PROBLEM BUT MINE ONLY COMES ON WHEN I AM IN GEAR, IDLEING AT A STOPLIGHT OR IN A DRIVE THRU. TOOK IT TO GM AND THEY ARE TELLING ME IT IS A "P0300 AND P0301" CODES WHICH SAYS IT A VALVE TRAIN MIS-FIRE ( TO FIX IT IS A 2000.00 HEAD JOB) AND THAT IS WHY THE STABILITRAK AND ENGINE LIGHT COMES ON!!! IN MY RESEARCH SO FAR I HAVE FOUND NOTHING THAT TIES THE TWO TOGETHER.
I HAVE 102,000 MILES ON MINE AND IT RUNS PERFECT AND MPG IS THE SAME AS THE DAY I GOT IT. I WILL KEEP YOU UP ON WHAT FURTHER I FIND. I AM NOW IN CONTACT WITH THE GM DISTRICT SUPERVISOR.
