Those extended warranties are written by "under-writers" similar to an Insurance company and you have to read the fine print. They vary from under-writer to under-writer. Get out your paperwork and go over it & there should be a list of what's not covered and a phone # to contact them with questions. IE: wear items like brake pads, u-joints, tires, wipers, belts, hoses, bulbs are NOT covered - engine parts "usually" are, but you have to call them. NOTE: some dealerships sell up to 6 different extended warranties.
