Ram has been investigating an issue with a number of heavy-duty trucks from the 2021 model year that have experienced engine bay fires. This has been going on for a little over a year. Then, for some reason, even when the engine is off, the solid-state intake heater relay in Ram trucks is fitted with the 6.7-liter Cummins turbodiesel can suffer a short and catch fire. The company is planning to recall about 20,000 vehicles in the U.S. and Canada this was in March of this year. It was thought to be a problem that was limiting to trucks with unprotecting relays. Then, in May, Ram did discover the issue was occurring even in trucks with protected relays. In fact, now Ram is preparing to recall 131,177 trucks from the 2021 and 2022 model years.
