I apologize in advance for the long post. I have had issues with leaks too. I picked up my 2019 Ram 1500 at the end of July, returning my 2015 Ram that gave me 3 trouble free years. In early September I discovered the rear carpets were wet, in fact they were saturated. I lifted the rear mat and found mildew on the underside and on the carpet. I read on this site about the dislodged sunroof drain tube grommets and discovered that one was dislodged. Given the amount of rainwater in the rear seat area I suspected that the grommet was not the only source of leaks. I took it in for warranty service, the grommet was repaired and the dealer found that the rear window was missing about 15 inches of sealant. The window was reinstalled properly and new carpets were ordered. The dealer informed me the carpets were not available and the manufacturer was stating they would not available until the middle of April 2019, remember this is September 2018. The service adviser sought the assistance of his District Service Manager but he was on vacation. I contacted with Ram's Warranty & Repair Help and was told a case manager would contact me in 24 hours, that never happened. About a week later I contacted them again and finally a case manager returned my call. She arranged to have carpets pulled from the production line and shipped to the dealer. Within a few days the carpets delivered and installed, as the tech was bolting down the driver's seat the nut, that is welded to the underside of the floor pan, broke free. The service advisor said he never saw this before. The truck had to go to a body shop where a section of the floor pan was cut out, the nut was re-welded in place, the floor pan was repaired and painted. Carpets and seats reinstalled and now the power rear window does not work. Because it's a new model the dealer did not have wiring diagrams and to obtain them from Ram. After 5 1/2 weeks the work was completed. The dealer had provided with me a loaner but it was a minivan and it did not fulfill all my needs. I had to rely on the assistance of other several times during the 5 weeks. The Customer Care Manager offered me reimbursement for 5 weeks of car payments or 2 years of oil changes and tire rotations. I felt that both were in order, the reimbursement since I was unable to use the truck and had to rely on others and the oil changes to compensate me for my bad experience. She refused and I took the reimbursement. A few weeks ago a started smelling a swampy odor; I looked/felt around and found the pads under the front carpet, both sides, were saturated. I have an appointment next week to have the dealer look at it. I contacted the Customer Care Manager via email to update her on the leak re-occurrence and got a reply that the case was closed; so much for customer care. Just as closing note my son dropped his 2016 Ram 1500 off for service today, the problem......... water leak.
