NHTSA Complaint #11527606 — 2020 RAM 1500

Since the vehicle was purchased new in 2020, the check engine light has come on and the service throttle body message has been displayed 12 times. It only happens when I am towing a 5,500 pound travel trailer. When the anomalies happens, I loose engine power. Say I am traveling at 65 MPH. When the anomalies happens and the CEL and warning messages appear, my speed drops to 32 MPH. Most Interstate freeway systems have a 45 MPH lower limit. I am forced to quickly pull over to the emergency lane to avoid a crash situation. If I shut off the engine and restart it, my power comes back but the CEL is still on. The selling dealership has tried to fix this several times. The engine code that is always present is a P00AF (turbo boost control “A” module performance, I think over boost) and at one time a P0299 (turbo under boost). The latter occurred after I heard a loud “whoosh” . The turbo air hose blew off. So far the Dealer has flash programmed the engine control module, replace the turbo hose and lastly replaced the turbo itself. Not all of the anomalies have been documented by the dealer, as I am always traveling around the country when it happens and have called dealers in the city nearest me at the time and have gotten every excuse as to why they cannot look as it now. I am almost always able to resume my travels by shutting off and restarting the engine. When I arrive back home and take it in to be looked at, I’m told there is no codes and no history of a code. It can be several thousand miles after the anomalies when the dealer finally gets to look at it. FCA (Chrysler corp) is aware of the situation and has opened 4 cases for my concern. Case # 77583210 which they immediately closed, # 78338328, #79796818 and just on 06-9-2023 case # 86383024. The vehicle now has 21,726 miles on it and most of them are towing miles. The vehicle specifications state this vehicle can tow 12,000 lbs. I bought this vehicle for vacations and towing. THIS VEHICLE IS UNSAFE!
