Service bulletins for the 2013 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.

N250508132021-03-15. Service bulletin. ENGINE AND ENGINE COOLING; POWER TRAIN; ELECTRICAL SYSTEM; VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM. New Safety Recall Advanced Communication ? N25050813 Chrysler Group LLC (Chrysler) announced a safety recall on certain 2013 model year (DS) RAM Trucks (1500 series) equipped with a 3.6L engine (sales code ERB). Some of the above vehicles were built with a 3-way coolant valve that may become inoperable due to an improperly soldered circuit board in the valve. If the 3-way coolant valve sticks in a position that does not allow coolant flow to the heater core, the vehicle will not defrost the windshield as specified in Federal Motor Vehicle Safety Standard (FMVSS) No. 103 - Windshield Defrosting and Defogging Systems. NOTE: The 3-way coolant valve controls the flow of engine coolant to the heater core and transmission heater. Chrysler will conduct a voluntary safety recall on all involved vehicles to inspect the date code on the 3-way coolant valve. 3-way coolant valves built within a specific date range must be replaced. The Powertrain Control Module (PCM) must also be recalibrated with new software. Dealers will be notified of the launch of this safety recall by way of established methods used in the past. We ask that you please take the time to ensure that your personnel are aware of this communication and are prepared to execute a customer friendly process for inquiries on involved vehicles.
