Summary Verdict

The 2009 Nissan NP300 is a workhorse vehicle that, while generally robust, exhibits some common reliability concerns typical for its age and utility focus. The diesel engine variants, particularly the YD25DDTi, can be prone to turbocharger and glow plug issues, while the petrol engine may face head gasket problems. Transmission issues, especially with the automatic torque converter and manual clutch wear, are also noted. Suspension components like leaf springs and steering linkage parts can wear out under heavy use. Electrical system vulnerabilities include alternator failures and potential wiring corrosion. Exterior rust is a concern, especially in corrosive environments. Interiorly, the HVAC blower motor is a common failure point. Despite these potential issues, with diligent maintenance and timely repairs, the NP300 can remain a reliable option for commercial use.
