NHTSA Complaint #11563901 — 2021 RAM 1500

high quantities of water leaking through the rear glass in amounts so great it even soaks the rear floor carpet in water after only a few minutes in the rain from running down the back wall of the cab. Water leaks down the inside of the back window directly onto and over the 48 Volt lithium ion battery pack, equipped in my ram Etorque model. this occurs even after small quantities of rain, after water testing it myself it is clear the water is going between the rear glass and the body and into the cabin. I have had this documented with the dealer twice, and called Ram corporate support multiple times, and receive the same answer, and even though I have a seven year 1,000,000 mile warranty, they refused to fix it stating it is not covered. however the exact same issue has created an extended warranty condition out to 10 years for ram 1500 models built between 2019 until September 30 of 2020. the build date of my vehicle is October 19 of 2020. 20 days later.. Corporate support refuses to believe this condition may have existed beyond their September 30, 2020 date. As it is well documented with the mass quantities of electric vehicle fires, created by lithium ion battery packs, I tried to file a safety complaint as well. The answer I received from Ram corporate was “the lithium ion battery pack beneath the rear window behind the rear seats is a sealed system, so it is OK if it gets wet” even though it is inside of the cab. The ram 1500s from my date range have known issues with water leaks through the rear center mounted brake light and through the glass due to cracked frames on the vehicles, sliding rear windows, such as mine, however they refused to believe any of those conditions may have transferred to my specific vehicle despite a $7000 extended warranty. I am Reporting this condition because I am afraid water intrusion onto a lithium ion battery inside the vehicle could result in loss of life as this system is now a standard feature on all ram 1500s as of 2022.
