Summary Verdict
The 2018 Volvo VHD demonstrates a strong overall reliability profile, characteristic of its heavy-duty vocational design. The most frequently reported issues tend to be concentrated in the engine and transmission systems, particularly with the EGR cooler and DPF on the D11 and D13 engines, and clutch actuator or TCM issues with the I-Shift transmission. These are not uncommon for high-mileage, hard-working trucks. Suspension components, especially air springs, can experience leaks over time. Electrical and interior systems appear to be relatively robust, with corrosion on chassis components being a more environmental concern than a design flaw. Proactive maintenance and addressing early signs of issues are key to maximizing the VHD’s longevity and minimizing operational disruptions.
