Owners of 2013 RAM 2500s report strong diesel fuel and exhaust fumes entering the cabin via the ventilation system, particularly during idling and DPF regeneration. One owner states the smell resembles charcoal lighter fluid vaporizing and caused nausea. Dealers dismiss the issue as "normal," but owners insist it poses a health and safety hazard. Separately, the water pump fails frequently (37,500–109,000 miles), causing coolant leaks and overheating; one case documents flames from the engine compartment during remote ignition. Recall 17V562000 was issued but parts remained unavailable for extended periods, with one vehicle sitting at a dealer 30+ days while awaiting replacement components. Engine knock at higher mileage (148K+) appears to be a chronic defect; multiple independent mechanics report rebuilding several 2013–2014 Cummins engines for the same issue. Intake manifold heaters fail, the turbo actuator fails, and transmission torque converters drain fluid back into the trans during parking, causing dangerous neutral shifts on grades. DEF system contamination and injector failures recur despite repair. Recalls 14V635000 and 67A were issued but parts unavailability prevented timely repair across dozens of vehicles, with manufacturers providing case numbers but little substantive relief.
