NHTSA Complaint #11494534 — 2018 RAM 2500

HCU failing. Blinks on display screen. Appears then disappears. When in cruise control and the HCU goes haywire, kicks cruise control off unexpectedly. When this occurs and the driver isn't expecting it, this causes panic because the vehicle rapidly slows down, nearly causing a vehicle collision if not prepared for it. I was almost rear ended due to this. Research on this failure would reveal this issue to be affecting 1000's of 2018 RAM trucks to have this problem. My local Dodge dealer advised I am approximately the 2500th person waiting on the part which is currently on BACKORDER. Have been a Police Officer for 15 years, safe driver and this nearly caused an accident on 695 Baltimore County, MD during heavy traffic.
