You probably did the right thing -- life is short. I had a similar experience and called an attorney, who explained that, in the U.S., you can really only sue for any actual loss (whether to the vehicle or to you). If you weren't injured or killed, and didn't suffer extreme anxiety or something like that, then you suffered no real loss and really have nothing to sue over (unfortunately). You can't sue for what might have happened, only for what actually did. (You probably could have sued, at least in small claims, for the loss of use, cost of repairs, decrease in value, etc, if you wanted to take the time.) With that said, you might have been able to get them to take it back under your state's lemon law, if you hadn't already sold it, but the lemon laws generally only cover multiple defects over a period of time anyway. :(
