We bought this car new from the dealer with an extended warranty. When driven at the suggested speed for any length of time on an open highway, the temp gauge goes up and the air shuts off. Withing a few minutes the temp gauge returns to normal but the air sometimes stays off. Has anyone else had this problem?
With the engine cold, check your coolant level. If it’s low. Add coolant and bring it to a shop to search for internal and external leakage.
