NHTSA Complaint #11569804 — 2021 RAM 1500

During cold rainy wether, water leaked in through rear sliding glass window and fried the BCM, which caused a complete shut down of all systems. I was not driving the vehicle at the time but if this had occurred while driving this could have ended in a catastrophic accident. In researching this issue, many ram vehicles have experienced this and/or similar issues including the vehicle stalling while in operation. When this issue occurred,, there were no warnings or prior indications. Additionally, water was found inside the passenger compartment. Also, the vehicle could not be manually placed in neutral so that it could be moved for towing. The tow service had to slide the vehicle onto tow trailer with sliders placed under the rear wheels. The was then vehicle towed to a FCA dealership.
