PS. I had called the service department, when it happened, where I bought this Yukon and asked the service manager if he had any reports of this occurring, and he said no, it was probably the rain had gotten into the drivers door switch and shorted it out.
I guess I won't be using their service department for repairs.
What did you really expect? They can't diagnose anything over the phone. And since it's a feature and not a bug, what else are they going to say?
