I have a Ram 2020 Rebel. Seems there are several areas that leak. That would be the top sharkfin antenna, the third stop light above the rear window, and the entire rear window. There's a lot of videos on line about this, and there was a class action lawsuit against Mopar, but it just got dismissed two weeks ago. In my case, I have cracking on the rear seal of the window above the sliding rear window and leaking from the stop light. It flooded out the RF Hub, which is against the back right of the wall of the back seat, and under a bunch of carpet. You'll never know it's there until it's too late. The RF hub killed the whole car bricked it.

I have had Ram/Dodge trucks for 30 years and I rage quit. I went and bought a Toyota today. I'm so pissed. This was my dream Ram and I didn't want to buy another truck. I'm concerned that Ram knows about this issue but does nothing about it. Some of the fixes would be easy, but they don't seem to GAF. For all these issues, it happens just after the warranty expires. How fortunate. If the RF hub shorts out when driving, I don't know what will happen. If the rear window seal is replaced, it's the same thing that is in there now. How will this help?

Started to get a BAD musty smell in the cab in the fall of last year. Took it to the dealer, Daystar Chrysler - who has been GREAT by the way, they had it for almost 2 weeks. They fixed a pinch weld that was causing the problem. The water had soaked the entire front carpet and padding. Started get the smell again in early Jan. of this year. Took it back. Its been a little over two weeks this time and It's still in the shop. This is by no means a slam against Daystar, they have been great to work with. I am a long time MOPAR fan and I believe I got a "Monday" truck. I have no doubt Daystar will get it right.

Update from Apr 16, 2021: Cab leaked a second time. This time from the area of the A-post. All total the truck has been out of service for 32 days.
