On my model year 2023 RAM 3500 equipped with the Cummins 6.7L High Output engine, the premature failure of the camshaft valve lifter has caused the engine camshaft to have abnormal wear due the valve lifter roller bearing seizing. This has also caused metallic debris to contaminate the engine oil causing further damage to other engine components. This potential safety hazard of this incident, potential catastrophic engine failure which may occur while driving and cause the vehicle to stop suddenly without driver input. According reports provided by multiple consumers and dealer service departments for this vehicle model, others have experienced the same failure. The vehicle has not been independently inspected. There were no warning lamps, the only recognizable symptom to the issue is an irregular ticking sound coming from the engine bay upon startup and at warm temperature idle.
