Well that is a perfect example why a viper alarm system is better than the factory security system with onstar. The factory system only keeps the car locked and even Onstar can't track wheels not attached to the car. For me wheel locks and Viper as soon as it leaves the dealer. It's still cheaper than the insurance deductable.
