Service bulletins for the 2014 Ram 1500

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

18015152023-01-09. Service bulletin. EXTERIOR LIGHTING. Malfunction Indicator Lamp (MIL) Illumination And/Or Intermittent No Crank No Start This bulletin involves inspecting the Charge Air Cooler (CAC) system for excessive water and/or ice and drying the CAC components if needed. It also involves installing a winter front cover.
R512022-12-19. Service bulletin. EXTERIOR LIGHTING; AIR BAGS. Customer Satisfaction Notification R51 Winter Front Cover The Charge Air Cooler (CAC) on about 8,000 of the above vehicles may develop internal icing in cold temperature regions. This condition may cause the Malfunction Indicator Light (MIL) to illuminate and cause the vehicle to experience a 35 mph limp in condition. A winter front cover must be installed when sustained day and night time temperatures drop below 30° F (-1° C).
S16250000052022-10-17. Service bulletin. FUEL SYSTEM, DIESEL; AIR BAGS; FUEL SYSTEM, GASOLINE; EXTERIOR LIGHTING. (Rev. A) Malfunction Indicator Light (MIL) Illuminated. Service Diesel Exhaust Fluid (DEF) System ?

S20250000012022-10-17. Service bulletin. EXTERIOR LIGHTING; BACK OVER PREVENTION. (Rev. B) Malfunction Indicator Lamp Illumination (MIL). Diagnostic Trouble Code (DTC) P203E ? Reductant Level Sensor 1 Circuit Intermittent-Erratic Set.
18-015-152022-09-26. Service bulletin. EXTERIOR LIGHTING; POWER TRAIN. Malfunction Indicator Lamp (MIL) Illumination And/Or Intermittent No Crank No Start This bulletin involves inspecting the Charge Air Cooler (CAC) system for excessive water and/or ice and drying the CAC components if needed. It also involves installing a winter front cover. A small number of customers may experience a MIL illumination when ambient temperatures fall below 32°F (0 °C). Upon further inspection, a technician may find the ? P0299 - Turbocharger Underboost Condition ? U1424 - Implausible Engine Torque Signal Received In addition, a customer vehicle may come in with a no crank/no start. This may have occurred after the vehicle has been driven for an extended period of time in extremely low ambient and then allowed to sit overnight. Further diagnosis may indicate a possible inoperative starter. A possible cause of these concerns may be contributed to internal icing of the Charge Air Cooler (CAC) system and intake manifold. Icing will occur because warm, moist air from the turbo charger is being rapidly cooled and the moisture is then condensed into liquid by the CAC. The liquid is then distributed into the rest of the intake system, which is operating at ambient temperature, where it will then freeze. Vehicles that are driven for extended periods of time are susceptible to higher amounts of ice build up within the intake manifold. Once the vehicle is turned off and allowed to sit, the ice formation in the intake will begin to melt due to the elevated underhood temperatures. The moisture will then run down the intake runners and accumulate in the combustion chamber through an open intake valve causing the engine to hydro-lock. To help prevent icing in the CAC system when the vehicle is operated in low ambient temperatures, it is highly recommended that the vehicle have winter front cover installed. This raises the CAC outlet temperatures above freezing which will help reduce condensation build up.
