Can I sue a dealership if I can prove faulty work?

None of this sounds right. You probably have more legal rights against the dealer than you realize. The cost for the extended warranty seems exorbitantly high. Putting parts on that you did not know and did not agree to, that's more than unusual and would be illegal in most states. Depending on what was being flushed, that doesn't sound right either. Here's some general rules. Your legal rights against the selling dealer, however, are mostly determined by the paperwork that you sign. Look to see if anything was written down about any kind of warranty or guarantee or right to cancel. Also there’s a federal law that requires all car dealers to post on the window of all used cars they are selling a special “Buyer Guide” form (it’s often called a Used Car Window Sticker) that discloses whether or not a warranty comes with the car. Many small lot car dealers don’t comply with the law. If they don’t, then you may end up with a warranty after all and you may even have the right to cancel the sale. The back side of the form has to be completely filled out and many car lots, big and small, fail to do that too and that can also trigger your right to cancel the deal. You can see what the Buyer Guide form looks like on this web site page: http://ohiolemonlaw.com/used-car-lemon-law.html. If you have any kind of warranty rights against the selling dealer, then the next question is whether or not your problem is covered by the warranty from the dealer. If it is, then they have to fix it. But you could easily have warranty rights and not even know it. You need to talk to a local Consumer Law attorney who deals with this kind of case (it's called "autofraud" or car sales fraud). You can go to this web site page for a Free Online 50 State National List of Consumer Law Lawyers (http://www.ohiolemonlaw.com/ocll-site/ocll-locate_local.shtml) and find one near you (lawyers don’t pay to get listed here and most of them are members of the only national association for Consumer Law lawyers, NACA.net). You can also look for one here on under the Find a Lawyer tab. Or you can call your local attorney's Bar Association and ask for a referral to a Consumer Law attorney near you. But act quickly because for every legal right you have, there is only a limited amount of time to actually file a lawsuit in court or your rights expire (it's called the statute of limitations), so don't waste your time getting to a Consumer Law attorney and finding out what your rights are.
