2011 Nissan Navara 3.0L Diesel · PX11 PSU

A cluster of major failures on the latest MOT points to systemic electrical and steering issues that dominate the vehicle’s current condition; the 2026 test recorded a power‑steering malfunction, a non‑functional engine MIL indicator, a fault in the supplementary restraint system warning lamp and non‑compliant LED front headlamps, all classified as major defects. This follows a previous dangerous failure in early 2024 where front brake pads were measured at less than 1.5 mm, and a series of recurring advisories about mud‑covered suspension and underside that suggest the vehicle has been operating in a demanding environment. The pattern shows a shift from largely advisory findings in 2020‑2022 to increasingly serious defects in the last two years. At 122,647 mi the Navara averages just over 8,000 mi per annum, a mileage rate that sits within normal bounds for a fifteen‑year‑old light commercial chassis. The MOT record shows annual testing from 2020 through 2022, a gap in 2023, then bi‑annual testing in 2024‑2026, indicating the vehicle has been kept on the road with no prolonged storage periods. The relatively steady mileage combined with the recent escalation in defect severity suggests that wear on consumables such as brakes, steering components and electrical systems is now reaching a critical stage rather than being driven by an abrupt increase in usage. Prospective buyers should verify that the power‑steering system delivers smooth assistance without whining or jerking, and listen for any pump whine or fluid leaks when the engine is revved. The engine MIL light must illuminate correctly; a dead or intermittent indicator could mask underlying faults, so a diagnostic scan is advisable. The SRS warning lamp must be extinguished after any fault is cleared, and the vehicle should be inspected for airbag module integrity. Both front headlamps must be replaced with type‑approved units, as the current LEDs are flagged as incompatible and could cause electrical load issues. Front brake pads should be measured again – any thickness below 1.5 mm will require immediate replacement, and the pedal should feel firm without pulsation, indicating healthy disc condition. The off‑side front wheel bearing, noted as having slight play, should be checked for grinding or humming noises during cornering and may need re‑greasing or replacement. The rear exhaust mounting, recorded as defective in 2021, should be inspected for cracks or loosened brackets that could cause rattles or excess vibration. Fog lights on both sides have been reported missing or dim; verify their operation or plan for replacement if needed. The repeated advisories about mud covering the suspension and underside imply potential corrosion of suspension bushes, subframe joints and brake pipes; a visual inspection for rust, especially on the brake pipe noted as corroded in 2022, is essential. Overall, a thorough mechanical appraisal by a qualified technician, with particular focus on steering, braking, electrical warning systems and corrosion‑prone areas, is required before committing to purchase.
