Has anyone had an experience with their ABS warning light staying on? My light came on at 206 miles yesterday. I called my dealer about it... (absolutely clueless..) I called Onstar and they ran diagnostics on her. They stated that there was indeed an error being reported with the ABS. I'm taking her in today to have the CAI installed and will have them look into this too. I was just wondering if anyone else had this happen to them.
