Common Diesel Truck and Fleet Problems We See in California
Our roads are tough on heavy-duty vehicles. From long hauls on I-5 to steep mountain passes, diesel trucks take a beating. Here are the most common issues we repair in the field:
1. Diesel Injector and Fuel Pump Problems
Fuel delivery issues are some of the most common problems affecting diesel engines. Look out for hard starts, misfires, or poor fuel efficiency.
2. Engine Overheating and Power Loss
When a diesel engine overheats or loses power, it could be related to a faulty cooling system, turbocharger failure, or worn gaskets.
3. Transmission and Drivetrain Failures
Whether it’s delayed gear shifts or fluid leaks, transmission issues are critical to address before they lead to full breakdowns.
4. Tire and Brake Failures
Don’t overlook tires and brakes — especially in high-mileage or heavily loaded trucks. Bald tires or failing air brakes can quickly lead to accidents.
5. Generator and Auxiliary System Failures
Diesel-powered generators or auxiliary systems often require attention, especially in specialized fleet vehicles.
