extended warranty

With the Major Guard contract, the list is what it does not cover. Glass, trim, paint,wear and tear items. In the top, the electronics are covered, but the weatherstrips, for example, are not. In the seats, the heater and cooling fans are covered, but the seat cover itself is not covered, unless the only way to get the heater element is part of the cover. The rear glass is not covered, but the grids in the glass for the defroster are, so if replacement of the glass was necessary to correct a defroster failure they would pay for the glass. These are not issues I have seen on this car, merely examples. The brake pads and rotors are wear items, as are belts, hoses, wiper blades, filters and the like. You can purchase the contract as long as the car is still in warranty. I do caution you to make sure that the contract is a Major Guard. There are different levels of coverage available.
Having dealt with a number of aftermarket companies in getting claims paid, I doubt you would want to spend the same kind of money for a contract that usually calls for LKQ parts in the performance of repairs. This is usually in the fine print, and depending on the company could be anything from used, remanufactured, or aftermarket parts. Not bashing the companies, but GMPP requires the use of new, GM, or AC Delco remanufactured parts in the performance of repairs at a dealer. The reman parts are generally alternators, starters, steering gears, engines, or transmissions. Radios are required to be repaired by the same AC Delco repair facility as the factory uses. It is your car and your choice.
