You can add me to the list of those with this problem. Tech said temperature sensor has error codes and will be replacing that first to see if the problem gets fixed. Its a special order part (isn't everything on this vehicle?). I sent this thread to the service manager and got the company line that they can't just be throwing parts at a problem, leaving it up to the tech to determine what needs to be replaced. Keep you posted.

BTW: seems like a number of us are having this issue. At what point does DC write a Service Bulletin? Do they track the number of common issues or do we need to notify someone there of this issue (and if so , who?).
