The driver side door on my Vue won't open. Thought it was frozen, but noticed that nothing sounds like it is unlatching when the handle is pulled. The power locks and power windows work. Called my Saturn dealer and they said it is a small part that may freeze up in the winter and will cost over 300 dollars to fix. This sounds like a defect on their part and I am wondering if this is something they should be taking care of. Can give me any answers?
