Your poll doesn't include "the GM ones are fine" which I think they are. I hear a lot of people point out the complaints on this board, but I think they are relatively few compared to how many people have them. And if they are on the vehicle from the factory, the warranty applies. I've never had any trouble with mine in almost two years and that includes two winters wwith lots of snow/ice and temperatures well below 0 F for extended periods of time.
