Sunday morning, our car's dash lit up like a xmas tree with all the faults. We made it to church and back home. Monday I had a Dr. appointment and the car was still working. We made it to the dealership and pulled into the inside drop off when one of the service writers came out with a scan tool to see if it could pick up any of the faults that may have been stored in history. Showed a bad battery. I don't know why, it was only 8 years old. They had to give it a jump to get the car into the shop area. Perfect timing to have the battery completely die at the dealer. $400.00 later we were on our way home.
