I've never had a problem with OnStar. In fact, I've had great service. Example:

I was driving home from Moab and my truck broke down in Salina, UT. I was ~2000 miles beyond factory warranty. OnStar had a tow truck to me within 15 minutes and covered the tow to Salt Lake City (a three hour, $300+ tow).

I understand your frustration, but one incident doesn't mean the service sucks.
