We had the similar issues and spoke (yelled) at GM/Buick Corp office. The problem is they used cheap wiring harness (not IP67/68) on many exterior connections (ABS, Fuel, etc..). We had to replace our fuel pump harness, which was causing a lot of the same issues you have, and it cost over $900. The idiots at the dealer didn't explain it to our ext warranty properly so they wouldn't cover it due to "water damage", but they do cover failed connectors. Hello!!! for water to get inside the harness had to fail...Hello!!!!
We brought it back in a year later for some service and they said it need to be replaced again. I just about destroyed the place.
FYI - We bought our 2003 new and still have it. We have over 175K miles. Outside of this issue the car has been great. Brakes, oil, tires and an occasional wash.
