Luck??? No, skill. I have 2 Cobalt SS's.
2006 SS/SC has 42,500+ miles on the stock clutch, full season of racing last year, many long road trips, lots of accelerations to rev limiter due to short freeway on ramps, and lots of mountain driving. No problems.
2007 SS/NA sedan w/ 5-speed has over 15,000 miles on the stock clutch. Started seeing racing within 6 weeks of purchase, a few long road trips, including a trip for Salt Lake City, Utah to College Station, Texas, lots of accelerations to rev limiter due to short freeway on ramps, and lots of mountain driving. No problems.
As you said, it may have been due to the previous owner and the fact that the first time it was repaired it wasn't done right. Luck had nothing to do with it. Let your tech fix it. It should have been covered under warranty anyways if it only has 319 miles. Go fix it and don't start throwing legal action around. So far, it sounds like your issue with the previous tech that did the repairs, not GM. For the record, I grew up in a home of people who work in the legal field. I think I know enough to know that you're only mad and probably can't afford to start a law suit anyways. You have to start the suit at your own expense, then you have to find co-plaintiffs, then you have to petition the court to make it a class action law suit and try to gets the courts approval. Good Luck.
