A preliminary investigation has been opened into certain Stellantis vehicles by the U.S. government due to an issue causing loss of motive power, reports Reuters.
The U.S. Office of Defect Investigations (ODI) is investigating model year 2022 RAM 3500, 4500, and 5500 trucks after receiving 82 complaints of an internal transmission failure of the K1 snap ring leading to loss of motive power.
The problem stems from the snap ring detaching, preventing the vehicle’s forward gears 1 to 4 from being able to function during a failure and disabling the vehicle.
Of the complaints received by ODI, 16 report experiencing a complete loss of motive power at speeds over 25 miles per hour, with no way for the vehicle to return to normal operation. Following tests conducted by Stellantis’ U.S. unit, FCA, the company said that drivers will see a warning message if such a problem occurs, and that gear 5 and reverse will remain functional.
