Twice my warning light has come on and the chime goes off while driving down the road and has stayerd on for over 30 minutes (very annoying). After parking it overnight, the issue is gone. I took it to the dealer Friday and they could not find anything wrong. There were no stored codes and everything checked out OK. When the brake idiot light and chime went off, no one was touching the brakes and we do not use the parking brake. Tried setting and releasing the parking brake but that has not helped. Has anyone else experienced this?
