Hello. Just found and joined the forum. Hope someone can shed some light on a problem I just encountered. The plastic control gear in the module of my power lift gate has stripped when I inadvertently tried to open it with a small film of ice on the vehicle. Gear cannot be replaced separately from module. Retail for module is over $800, GMPartsdirect.com is just over $500.00. My dealers first reaction is it is not covered under warranty. My understanding is the gate is sensored to detect resistance and stop to avoid damage to gate and/or injury to person. In this situation, it didn't. Vehicle has less than 29,000 miles and this should be covered under warranty. I am pursuing with Dealer again. Anyone have similar experience or advice? Thanks.
