Summary Verdict
The 2018 Volvo VNR demonstrates a generally strong reliability record, particularly with its core powertrain components when properly maintained. The I-Shift transmission is robust, though occasional actuator or module issues can arise. Suspension systems, especially air suspension, can experience leaks or valve problems typical for the technology. Electrical gremlins, such as wiring harness faults or alternator failures, are not uncommon in heavy-duty applications and require diligent inspection. While the DPF system on the D13 engine can be a point of concern if regeneration cycles are not managed correctly, overall, the VNR is considered a dependable choice for commercial fleets seeking a balance of performance and durability.
