here is the DIY video and parts list.water & salt, not just cold weather, is what is causing it to corrode. summer time has plenty rain, so you wont have to wait till next winter to get failures.
i would start by going to the dealer and stating you get the blue screen. tell them its frequent enough for you to be unhappy. they may just change it.
otherwise, you are sitting on a ticking time-clock as to when, not if, it will fail.
you can watch my video, and see if you want to apply silicone where i did, and see if that helps. i just checked mine a few days ago, and the black RTV is holding up well.
