I bought my car used and have had it for a year now. At 4 months I had to replace the brakes, at 6 the starter, at 9 month the battery, 10 the alternator, and now at 12 month it has started shutting it's self off any time I'm at a light or yeald sign. I've taken it in several times because the check engine light keeps coming on and they clear the "code" and tell me it's ok nothing is wrong or that I just didn't put my gas cap on tight enough. Really how tight does the gas cap have to be??? Talk about a lemon.
