“We were driving 55 and the car stalled. This has happened several times. Been at dealer and the codes show fine they replaced what they thought was issue and it still does this. Very scary”
“Happened twice within a day. The main electric fan on the radiator stopped working and the car overheated. Once at idle, was able to shut the car off safely. The second time, there was traffic on the highway, and the fan stopped working and the car started to overheat. Had to shut the car off and wait for it to cool down on the side of the road. When I got the car home, I found the electrical connector of the fan to be melted and fused together. There was no indicator that the fan would stop running prior to the engine overheating.”
