Let's not forget we're talking about a company here that built a minivan (Venture) for something like 7 years with a crash cage that folded up like a house of cards. In the IIHS crash test, the front of the van came right in on the crash test dummy, taking off its legs, and earning the Venture a failing grade and the lowest safety rating of all the minivans on the market at that time ('97 to 2004?). I almost bought one of these things in '02 until I saw those crash test results. When I called GM to ask for an explanation their response was that they didn't agree with the IIHS' findings and instead preferred to look at 'actual crash data' - which meant you were safe in their vans until you were involved in an offset head-on collision ... then you were probably learning how to walk with dual prosthetic legs.
So the point is - GM has turned a blind eye in the past, refusing to correct problems in the middle of a production run (because, in their opinion, there WASN'T a problem). Maybe "NEW" GM will be different, but that remains to be seen. Personally, I don't think I would buy the current generation Equinox knowing what I know now. Fortunately, I've been lucky so far with my V6 (12,000+ miles and no problems), but maybe I'm only about halfway to the gates of Hell.
