Feb. 17, 2023–Ram has recalled about 306,165 heavy-duty diesel trucks due to an overheating issue, according to Consumer Reports.
The problem affects “Ram 2500 and 3500 pickup trucks and 3500, 4500, and 5500 cab chassis trucks” made between 2021 and 2023.
The issue is caused by the heater-grid relay overheating and causing a fire risk. Ram is aware of six instances of vehicles catching on fire–all but one of them while the vehicle was running.
All recalled vehicles also have 6.7-liter Cummins diesel engines and older heater-grid relays from a previous recall.
Ram has advised those with affected vehicles to not park them indoors. No injuries or deaths have been reported as a result currently. Ram has not announced a resolution or plans to help owners repair the defective part.
