Update....I took the car into the local dealer on Sat to have it looked at. The remote start also wasn't working, but the girl at the service desk said whenever the engine check lite is on, the remote start is disabled. So much for that issue. Once they had a chance to look at it, she called to say that somehow, some wiring broke loose around the front of the engine, and they think it shorted out when it contacted the fan assmby, and caused the problems.
The worst part is that she said my extended warranty, which runs to 80,000 ( my car has about 55,000 now ), may not cover these repairs. I would think that if a bracket or wiring holder failed and allowed the wiring to drop down, then the bracket or clip should be a warranty item, and all damage caused by the failure downstream should also be covered. Has anyone had any experience with an item that failed and wasn't covered ? Is it worth calling Pontiac direct if they won't pay for it ? They still have the car and won't know more until Monday.
Meanwhile I'm paying for a rental car. And to make my day worse, on Friday, my wife hit a pothole and caused the right front hub on our 2004 Aztek to go out of square, which had to be replaced on Sat. Those aren't cheap...400$ out of pocket cause this one has 120,000 on it. Oh well.
