2022 Ram 1500: water leaks into the cabin

Filed Nov 8, 2026 · Body · FL

Water enters the cab at both upper rear corners at the rear window frame with every rain, and the rear defroster has failed (likely due to corrosion from the water leak). My concern is where the water terminates. The rear cab wall behind the second-row seat carries the RF hub and the 48V eTorque battery pack. Water intrusion along this path is the leading documented cause of RF hub failure on these trucks, producing key-not-detected faults, TPMS faults, and no-start conditions. That module is VIN-locked, so there is no inexpensive remedy once it corrodes. There were no warning signs other than the rear defroster stopping, and further inspection uncovered a water leak. The dealer confirmed the leak but denied it under the extended warranty.

Water intrusion into front of cab. Leaking from storage cavity at top of windshield. May have been the cause of failure of heated seat and heated steering wheel assembly. Dealer has been notified of water leak, and has asked for video evidence prior to repair. Further research has stated that other electrical systems (including key safety components) can be damaged by water leaking from above, as well as mold growth in the headliner. There was no warning, and I only happened to notice when entering into the truck on a rainy day.
