For those who have the courage to fight against dealers, the Magnuson-Moss Warranty Act hurts dealers who don't pay legit warranty claims. They have to prove what you did caused the failure, not that you didnt service it like they "require." A dealer refused to fix a cross member bolt in a chevy I had, instead of getting mad, I hired a lemon law lawyer and won 13 grand, lawyer got 3 of it. And that was the settlement on courtroom steps, because judges do not favor dealerships and they know it. If someone tells you that you need to eat a **** sandwich, say no thank you sir I prefer apple pie. It was one of the best days in my life when my lawyer handed me that check.
On a side note, never tell the dealer or their minions what your service records are, just tell them to freaking fix it or refuse in writing and say the words Magnuson-Moss Warranty Act. If you say something it becomes evidence against you, it helps them not you. Again, they are the ones that have to prove a legit reason to deny, it is their burden not yours. If they refuse to give you a refusal in writing, send them a certified mail with your contact info and make a legal statement you feel that they violated your rights. Under Magnuson they get punitive damages for unjustly denying warranty, which is why they settle on courtroom steps, they simply will not allow a case go to judgement, not to mention they have lawyer fees to pay.
Sometimes you just got to fight that big bully.
