We were stopped at a traffic light, began to move when the driver instrument display went red, said coolant was high, the car stalled, and we were hit from behind by another SUV. After we were able to restart it, the display returned to normal. We waited for the police to arrive, got an accident report and now the car is at the dealer. Also, before that the radio display was acting up with lines in i like a bad television then it would shut off. The dealer says it needs a new radio (on a 4-year-old Jeep), and they want to apply updates that SHOULD fix the issue.
