You may have a lemon law claim. The criteria for such a claim are very narrow. You need to start the process by yourself because the law does not automatically pay for attorney fees if you win the claim. Try the link to start the claim.
While Toyota usually builds a good vehicle, this one doesn't sound like it. Sounds more like a lemon to me but you don't mention if you bought it new or not. Every state's lemon law is a little different but in Texas a lemon is defined as 4 unsuccessful repairs when 2 occurred within shorter of 1 year or 12,000 miles, and other 2 occur within shorter of 1 year or 12,000 miles immediately following second repair attempt; or 2 unsuccessful repairs of a serious safety defect when 1 occurred within shorter of 1 year or 12,000 miles and other occurred within shorter of 1 year or 12,000 miles immediately following first repair; or 30 calendar days out of service within shorter of 2 years or 24,000 miles and at least 2 attempts were made within shorter of 1 year or 12,000 miles.
Your legal rights are triggered by sending written notice to the manufacturer and a state-run arbitration process is available. But don't do any of this by yourself. You should talk to an experienced Lemon Law attorney in your state who knows your state law. If you don't know one, call your local attorney Bar Association or look for one near you on this National List of Lemon Law Lawyers here: http://ohiolemonlaw.com/locate-a-local-attorney.shtml
I would strongly disagree with Ms. Trevino's comments. You always should use an attorney. If you go through arbitration and lose, that evidence can usually be used against you later. An attorney should be able to represent you at no cost because at a minimum, you should be able to get attorney's fees under the Magnusson-Moss Warranty Act. Get an attorney, never go it alone. You can try calling Travis Shackelford at Consumer Legal Services, PC at 734-261-4700. I believe he is a Texas attorney that handles lemon law claims.
Also, the lemon law list provided by the one attorney is a paid advertisement website. You should consider going to google and trying to find a lemon law attorney that way. I hope this helps.
Actually the National List of Lemon Law Lawyers is NOT a paid listing at all and it NEVER has been. Any Lemon Law lawyer who asks to be listed is freely listed after a short vetting of their competency which I personally conduct. It was created by me about 8 years ago specifically as a response to the paid lawyer listings that are seen on the internet which often do not look like a paid listing at all. I also absolutely agree with Dan Ruggiero's advise about using an attorney and being wary of any arbitration process, state run or not. After 30 years of Lemon Law work I can very confidently say that consumers who use lawyers to get rid of lemon cars typically come out better than the ones I have seen who go it alone. This is one area of law that is more complex than many consumers realize and Texas' Lemon Law presumptions are a good example of why any Texas consumer ought to talk to an experienced Lemon Law attorney for help.
In Texas, the only way for a consumer to get attorney paid by the dealer/manufacturer is if the dealer/ manufacturer responds to the administrative claim by and through an attorney which does not always happen. I'm not saying a consumer should not consult an attorney, but they should be aware of the possible costs. Also under Texas Lemon law, there is still a cause of action for deceptive trade practices against dealer and manufacturer for have stated that the vehicle was repaired when it was not. That part of the claim really needs attorney skill.
