Frequently Asked Questions

  • What is considered a medium-duty truck?

    Medium-duty trucks typically fall within Class 2 through Class 7, including box trucks, straight trucks, service body trucks, municipal vehicles, and contractor fleet vehicles such as the Ford F-550, Freightliner M2 106, Isuzu N-Series, and International MV Series.


  • Why is my medium-duty diesel truck in derate mode?

    Engine derate is commonly caused by DPF restriction, DEF system faults, SCR efficiency issues, EGR failures, or sensor communication problems. Medium-duty trucks operating on stop-and-go delivery routes are especially prone to aftertreatment issues that trigger power reduction.


  • How often should a medium-duty truck be serviced?

    Most medium-duty diesel trucks require oil and filter changes every 5,000–15,000 miles, depending on duty cycle and load conditions. Preventive maintenance should also include brake inspections, suspension checks, coolant service, and emissions system monitoring to prevent downtime.


    We also service semi-trucks in Lenexa KS. 

  • What are common problems with medium-duty delivery trucks?

    Common issues include DPF clogging, injector wear, turbocharger faults, brake wear from stop-and-go driving, cooling system failures, and suspension fatigue under heavy loads. Regular fleet maintenance helps prevent unexpected breakdowns.
