NHTSA Complaint #11479477 — 2022 RAM 2500

I recently purchased a 2022 Ram 2500 equipped with the u-connect 5 system and the 12 inch display screen. The 12 inch screen controls all radio, navigation, phone and climate functions. After driving the truck for an extended period of time, the 12 inch screen will lock up and all functions are lost. I was told by the dealer to "reset" the display by pressing the volume and tuning buttons simultaneously, and after that to do a "hard reset" through the radio controls. This does correct the problem, but it will eventually lock up again. The dealer advised me they must be able to recreate the problem to diagnose it. They also advised due to the extended drive time for the problem to occur, they would probably not be able to recreate the situation. I have contacted Ram and u-connect about the issue, and they too advise the dealer must be able to recreate the problem to fix it. They also indicated they have never had anyone else complain about the screen locking up. When I google this issue I have found numerous articles online posted by people experiencing the same issue, so I know I am not alone. My reason for contacting NHTSA is the loss of the climate controls, specifically the windshield defroster, when the radio screen is locked up. Many times in my life I have found the need to very quickly activate the front windshield defroster to maintain visibility. I am concerned if the screen is locked up, and the defroster cannot be activated, a crash may occur.
