Stellantis (Fiat/Chrysler) is recalling 20,000 heavy duty 2021 Ram trucks due to a potential fire hazard. Stellantis is blaming a heater relay that can short, overheat and catch on fire. Extra worrisome, the fires can start even if the engines are turned off. The recall is expected to start April 30. Ram trucks involved in the recall can be checked on NHTSA’s website.
