Well after the dealership had my 2021 Ram 1500 Big Horn with 4879 miles on it for 2 weeks I got it back. Rf module shot I told them I thought there might be water water coming in. They said they checked and couldn't find any leaks. I call BS. The very same night it rain and I got in the truck and behold, water coming down the passenger side rear window. Well I've decided to check all the common issues on this forum, but it still leaks. I called my service advisor and what? He quit . Now I left feedback with Ram about my situation. I'm gonna go and talk to service Mgr. I can't lose my truck for another 2 to 3 weeks and they were very hesitant to give me a rental. I should say my truck is still under 3 yr. 36000. warranty.
