About a month ago I had this auto shop replace the engine in my '97 Thunderbird. The guy was able to find a used engine with (what he said had) 70k miles. He put in the engine and replaced just about everything else; belts, filters, gaskets, mounts, did pretty much everything needed to keep the car running for a few more years. With this job came a 6 month warranty on all parts and labor. The car was running fine up till about a week ago. I was on the freeway and it started misfiring real bad, had no power and then the check engine light came on. After about 20 seconds or so of that it went back to normal. Later that day I had my friend pull the code and, sure enough, it was a random misfire code. The same thing happened again later that day when I was coming home on the freeway. Lost power and started misfiring, even worse than the time before. And, when I pressed on the gas a lot of white smoke came out of the tail pipe. White smoke = burning coolant, so probably blown head gasket. The car drives fine most of the time but I never know when its going to happen again or when its going to completely die out. That last incident was about a week ago, I have not driven the car since. CLIFS: 1. Have shop replace blown engine in my car. 2. Shop gave me 6 month warranty on all parts and labor. 3. Car runs fine for about a month then starts having problems. 4. Car continues to run but is not reliable. Yesterday I took the car back to the shop that did the work and told the mechanic what had been happening and he takes a half assed look at the car. He opens the radiator and pours in almost half a gallon of anti-freeze. Then he gets out his diagnostic tool and pulls the check engine light code and tries to tell me its not for a misfire. He wont tell me what it is, just that its not a misfire code. I kept telling him about how it was behaving on the freeway and about all the white smoke but he just dismissed the misfiring to bad fuel or a bad injector and just kept telling me that the engine was good and strong. When I iterated that it had been putting out white smoke his response was "well its not smoking now". He was not even willing to take a thorough look at the car. Its pretty clear that he is just feeding me bull shit because he does not want to honor the warranty and fix the problem. Is there some kind of legal action I can take against this guy? How can I force him to honor the warranty and fix the car? CLIFS 2: 1. Took car back to shop that did the repairs. 2. Mechanic did a half assed investigation. 3. Completely dismissed what I told him. 4. Will not honor warranty or even try to fix the problem.
