I have a 2019 Ram Laramie 4x4 with 31,000 miles on it. The RF Hub which controls the truck's ignition system has now failed twice. Ram Care just says you are out of warranty, we cant help you. I have paid out of pocket once to fix this issue created by a horrible design flaw (the window and 3rd tail light leak and the RF hub is situated directly below this). Now, 8 months later I have a dead truck again. Thank goodness this did not happen in the back country. Ram used to be a great company, but they now sell very expensive garbage with ZERO customer service. I will never buy another Ram after this experience and I will do everything in my power to prevent others from making the same expensive mistake I made.
If you do the repair, I would suggest replacing both the cab tail light and the back window. I only replaced the 3rd tail light the first time, I guess I should have paid to replace both. The water is likely getting in from one of those 2 spots. So frustrating!
