If they don't want to cover it, contact a lemon law lawyer. Don't do it yourself. By law (in Pa anyway), it's free to you. Even if you want to keep your vehicle after it's fixed, you are still entitled to a cash settlement (provided all the time stipulations are met). When the wife and I did her Kia, we were offered one amount to fix it and keep it, and another amount to trade it in. We took the money and traded it on a cherokee. While not as much as the first offer, they still paid back every one of our payments.
