I have a 2000 deville DTS with 75000 miles, has the northstar v8 sometimes the "service stability system" light comes on and sometimes the "service security system" come on these do not stay on and when I have taken it to 2 different cadillac dealers they claim they can not find any thing and supposively reset the codes, but they continue to come on sometimes. Nothing seems to be wrong with the car, what can I do to reset and keep these warning lights from coming on?
also car uses abuot 1 quart of oil per 1000 miles, I have been told by dealer this is normal for a Northstar, is this corrrect? (I change oil every 3000 miles)
Thanks for your help!
have the same problem?
