Summary Verdict
The 2007 Volvo VNM is a dependable commercial truck, especially when equipped with the larger D13 engine and either the I-Shift or a robust manual transmission. Key areas to monitor for potential issues include the diesel particulate filter (DPF) and exhaust gas recirculation (EGR) systems, which are common to modern diesel engines and can be sensitive to operating conditions. Electrical gremlins, particularly related to wiring harness integrity and control modules, can arise due to the demanding operational environment. Suspension components, especially air springs, may require attention over time. Overall, with diligent maintenance and proactive attention to potential problem areas, the 2007 VNM offers strong reliability for its class.
