4.7L Magnum:
Known for potential cylinder head issues (de-lamination), spark plug ejection, and water pump failures.
6.7L Cummins Diesel:
Early models could experience issues with EGR (Exhaust Gas Recirculation) systems and Diesel Particulate Filter (DPF) regeneration, especially if primarily used for short trips. Fuel injector reliability can also be a concern if fuel quality is poor.
Transmission (45Rfe/545Rfe):
Can be sensitive to low fluid levels and may develop harsh shifting or delayed engagement if not properly maintained.
Front Suspension/Steering:
Wear on ball joints, tie rod ends, and steering gear can occur with higher mileage and heavy use, leading to steering looseness or wandering.
