NHTSA Complaint #11465251 — 2020 RAM 1500

The BSM service notice triggered a shut down of all controls associated with front windows and climate control. The UConnect system shuts down completely and the climate system defaults to defrost with fans going to max and the heat turned up to Maximum temp. With front windows control disabled you are unable to lower or raise windows and with Uconnect shut off there is no way to turn off the heat. This takes place while driving. You are literally cooking inside the vehicle The BSM service light came on to indicate service needed on a sensor located in the tail light assembly. That notification triggered the electrical malfunctions of the other systems. After sitting for 12 hours the truck systems would reset. As soon as I started driving the same sequence of events would take place again. I repeated this every day for 4 days while waiting to turn this into a dealer for investigation and repair.
