2007 mazda cx-7 had failure of the air conditioner compressor. Bearings freeze up in the compressor unit. This causes pulley to stop turning and putting pressure on the drive belt. This causes car to overheat and battery to lose charge because alternator and water pump are not spinning. They do not spin because the drive belt slips over them because air conditioner pulley has seized up. This happens around 34,000 miles and generally within months of the expiration of the 36 month warranty. Internet research shows that this is a known problem to mazda. Mazda refuses to cover repair under power train warranty as it is not an essential part - even though the car become undriveable.
