I've been through lemon law/breach of warranty litigation a few times over the last 25 years. In my experience and discussions with lawyers, I have found that dealers and manufacturers (business in general) are not your friend and do not really care if you are inconvenienced, would prefer to negotiate with them instead of through the courts, or want to stay in "their family".
Know who you are talking to and be careful what you say or sign if you want to "represent yourself". Just like the police say - anything you say, can and will be used against you... Document everything - who you talk to, when, where, about what. I believe Texas is a one party consent state - you may want to verify the legality of recording any conversations you may have from this point forward regarding your vehicle.
This is a big deal - talk to an attorney in your area that specializes in lemon law/breach of warranty/consumer protection law (ask about a free consultation or pay for an hour of their time if you need to). Know your rights and understand what you need to do, and when, to preserve them. I have had some lawyers that have taken cases on contingency and others that wanted a retainer upfront to cover filing and administrative fees. At the end of the day, it all comes down to your risk tolerance level and how quickly you want things to happen. If you are risk averse and just want out of the situation, you will probably get hosed. If you have a higher tolerance for risk and are okay waiting a few months to a year for resolution, you are more likely to come out ahead in litigation.
