I know it's not a grand prix.... But it's a GM. So I was driving my mom's van to go pick something up for her and I had the cruise set at 60 and then all of the sudden it kicked off and about a couple of seconds later the ABS/TRAC OFF/SERVICE TRACTION SYSTEM lights came on. I had the radio up so I couldn't hear any sounds... So what do you guys think... New hub? The van is a 2003 Olds Silhouette.
