it depends on the lemon law in your state. out here in ca, we were covered well. im not sure how it is in your state, but in ca if you purchased a vehicle new, and there have been four or more attempts to repair a problem that cannot be resolved, you are entitled to file the car as a lemon. after that, you will be assigned an agent from the bureau of automotive repairs who will get a statement from you concerning your oreal. after this he/she will ask you for your work order records concerning the problem with the vehicle, and then the agent will ask what your demands are from the seller.
if the agent determines that your claims are accurate and fall under the guidlines of your states' lemon law, he will go to the seller (dealership) and ask that they meet your demands. if they stand firm and do not want to pay for repairs, than the agent will file a small claims court hearing in which you can sue for 10000 dollars in repairs and restitution. if the agent believes you are in the right, they will make a recomendation to the judge in your favor.
it all begins with you finding your local branch of better business bureau who will point you in the direction of your local bureau of autmotive repairs. i know because i just went through this with our mini cooper S that we bought brand new and that had an ongoing problem with its timing chain from the very beginning of ownership. we took ti this far, and BMW didnt budge on it until they realized that there was a small claims hearing that was being filed and that they were about to be ordered to court. they were the most snobbish, rude and self absorbed company, and treated us like crap until the state got behind us. after that, they treated us like royalty, paid for a complete overhaul of the motor, and gave us a warranty on their work after the fact.
GET YOUR RECORDS TOGETHER, LOOK UP YOUR STATES LEMON LAW, SEE IF YOU QUALIFY BASED ON SERVICE HISTORY AND FIND YOUR LOCAL BBB OFFICE. IT WILL TAKE SOME WORK, BUT IF YOUR ARE IN THE RIGHT, YOU WILL WIN. WE DID, BELIEVE ME, WE WENT THROUGH THE SAME NIGHTMARE YOU DID (PROBABLY WORSE) AND IN THE END WE DIDNT PAY A DIME FOR THE NEW REPAIRS AND GOT A WARRANTY AFTER THEY FIXED IT. GOOD LUCK!
