First post to forum. Last week my ctd gave me the message that engine was warm enough to self shut down the a.c.. 2 minutes later it started yelling at me to shut the car down. Temp was at the redline. Paid to get it towed to local dealership and paid for diagnostic which revealed absolutely nothing. I'm super upset. They couldn't duplicate the scenario after it got to them. Now I'm $250 short and the issue was not resolved. Any advice ?
