If I may add to this, I have an 04 and I live in MN. I got new LCA's thanks to the recall, but there was nothing wrong with mine. I never paid specific attention to them, but when I heard about the recall, I jacked the Jeep up and inspected them closely. There wasn't even one spot of rust on either of them. I've never been extremely meticulous about cleaning the under carriage. I wash the truck once or twice a week when the weather is nice, but during the winter I only wash it when the temp gets above 20. I've seen doors freeze shut before and don't want to be one of the unlucky ones it happens to. Anyway, I'd have to believe it's primarily owner neglect based on what I've seen. There have been a few reports about the LCA's failing and people losing control of the vehicle. I'm guessing the recall is just a result of that, and DC is trying to preempt a lawsuit.
