hello!

If the shop performed maintenance services or repairs without your authorization, you are under no obligation to pay for those services. Furthermore, in most states they cannot withhold your vehicle pending pending payment; the only method they ahve of securing payment for repair services is by taking he signed estimate or authorization for repair to court to obtain a mechanic's lein on the vehicle. if they have no such signed repair authorization, they would have a very difficult time in court forcing you to pay for those services.

As far as warranty on their repairs, their warranty policy should be printed on the repair order. If your vehicle still has the same problem after repair, they may be obligated to repair it for you again under warranty (you would have to consult an attorney with the specifics of your case for an accurate expert opinion on this matter).

I hope this is helpful; if so, pleae click my accept button! Thanks!
