HmmmmmmmmGM builds crap, and has for 30 years or so. Import cars (not to mention Ralph Nader) wouldn't be as popular if they hadn't, and GM wouldn't have had such financial troubles. That's not to say that all GMs are crap, their trucks, for instance, have always been good, and through the 70's 80's and 90's there have always been a few good cars from GM. Even now though, they sell crap. Uplander anyone?
They've made quite a bit of progress though, and I'd say most of their current lineup is quite good.
Anywho, you can't look at the problems section of an internet forum and make a judgement about reliability.
