I was told I had a rear window leak last year. This was on a brand new 2020 that I got in the Spring of 2020, so it was only slightly over a year old at that time. All my gauges would randomly stop working properly, and then would usually be fine again after driving a bit. It ended up being stuck in the electrical issue, and then my local dealer took a look and said they needed to update the software. They did that and all was good for a short while. I had to bring it in a 2nd time for the issue starting again, and then they replaced the rear window...saying that water was getting behind the panel. Everything seemed to be okay, except that the same issue randomly happens after the temps hit around 83 degrees. Now I just went outside, and part of the rear window decided to break on its own. This is getting ridiculous. I am calling the dealer tomorrow to see if they are even going to help. I do have an extended warranty on it, so I would hope they will cover this defective truck!
