I told them that I no longer interested in that car since they can t fix it but they refused to return it and they told me they will fix it soon
What to do about that ??
Thank you

Most every sate has a lemon law. In my state, on a brand new car, during the first 12 month or 12,000 miles if it cannot be repaired after 4 attempts OR the problem causes your vehicle to be out of service for at least 30 days you can invoke the lemon law and demand a new car. I did this in 1977 when I bought a Chevrolet Beretta that they could not repair. I got a new Beretta and paid not one dime. Look up your state lemon law. Be sure and keep a record of every time it has been in for service and how long.

Have they given you a loaner? If so, let them keep it – you are running up miles on the loaner and not on your car. They'll fix it eventually and in the meantime you are not wearing out your car, just theirs. Good deal! Plan some long trips before they fix it – take advantage. Your state might have a lemon law, look it up, but I highly doubt you would have been dealing with this long enough to qualify for it yet.

You must be mistaken. Everyone here keeps blowing how good Toyotas and Hondas are made.

Most states have a lemon law. Check into your state lemon law and see what if anything you can do.
