The backlite window on my 2019 RAM 1500 Laramie (VIN: KN655467) has a recurring leak that has resulted in water intrusion into the vehicle. This water damage led to the failure of the Remote Frequency (RF) hub, a critical component responsible for recognizing the key fob and enabling the vehicle to start. The issue has also resulted in corrosion to wiring harnesses and electrical components. The vehicle is available for inspection upon request. This issue has put my safety at risk on multiple occasions. The vehicle has repeatedly failed to recognize the key fob, rendering it completely inoperable. On two separate occasions, I was left stranded and had to have the vehicle towed. Additionally, electrical failures pose a fire hazard and could potentially affect other critical systems while the vehicle is in operation. The issue has been confirmed and reproduced by the authorized RAM dealership. The dealership determined that water intrusion from the backlite window caused the failure of the RF hub and other electrical components. Despite this, RAM/Stellantis has refused to replace the backlite window under warranty, only applying a temporary sealant fix that has repeatedly failed. The vehicle has been inspected by RAM dealership technicians multiple times. Each time, the dealership has confirmed water intrusion as the source of electrical failures. RAM/Stellantis has been made aware of the issue but refuses to properly address it. There were no warning lamps or messages before the initial failure. The first symptom appeared when the vehicle failed to recognize the key fob and would not start in November 2024. After the RF hub replacement, the issue reoccurred, requiring additional repairs.
