Severe-duty schedule
For vehicles that operate under severe conditions, such as towing, driving in dusty environments, short trips, or in cold climates, the maintenance schedule should be adjusted. The oil change interval should be reduced to 10,000 miles, and the air filter and fuel filter should be replaced more frequently. The transmission fluid service and differential service should also be performed more often.
Known issues by mileage
- 60,000 miles: Some owners have reported issues with the DEF (diesel exhaust fluid) system, including sensor failures and clogged injectors. It is important to have the DEF system inspected at this interval.
- 100,000 miles: The water pump and thermostat may need to be replaced at this mileage. Some owners have also reported issues with the turbocharger.
- 150,000 miles: The EGR (exhaust gas recirculation) cooler may need to be replaced at this mileage. Some owners have also reported issues with the fuel injectors.
