2012 Isuzu Rodeo 3.0L Diesel · WJ12 MXZ

The most recent MOT test on the 2012 Isuzu Rodeo, conducted on 2026-05-26, resulted in a passing grade, though it did not entirely resolve the vehicle’s persistent issues. While this marks an improvement over the previous failures in 2024 and 2023, the advisory items—particularly the recurring wheel bearing play on both front axles and the offside front lower suspension arm ball joint—suggest ongoing wear that has not been fully addressed. The presence of these advisories indicates that the vehicle’s front suspension components are degrading over time, with the ball joint and wheel bearings showing signs of excessive movement, which could lead to further alignment or steering system complications if not monitored. The brake pipe corrosion advisories, though not failing the MOT, are a critical concern as they indicate fluid ingress and potential long-term structural compromise, warranting immediate attention to prevent leaks or failure. The recorded mileage of 110,782 miles for a vehicle aged 14 years represents a moderate annual usage rate of approximately 7,913 miles per annum, which is within the expected range for a Rodeo of this vintage. However, the MOT history reveals periods of both high and low usage, with notable failures occurring at roughly 100,000 miles and 110,000 miles, suggesting potential gaps in maintenance or prolonged idling that accelerated wear. High-mileage components such as wheel bearings, suspension linkages, and brake systems are particularly susceptible to fatigue, and the consistent advisories on these items imply that the vehicle has not been serviced to address these issues comprehensively. The brake pipe corrosion, in particular, may have developed due to prolonged standing or improper fluid management, further emphasizing the need for proactive maintenance to avoid costly repairs. Given the recurring advisories on wheel bearings and suspension components, the prospective buyer should conduct a thorough inspection of the front suspension system, focusing on the ball joints, control arms, and bushings for signs of excessive play, cracks, or wear. During a test drive, listen for unusual clunking noises from the front suspension, especially when negotiating bumps or at low speeds, as this may indicate loose or failing components. The wheel bearings should be checked for excessive noise or vibration at low speeds, and any binding or grinding during cornering could signal bearing failure. The brake system should be tested for even pedal travel, absence of pulsation or shuddering, and proper response to braking pressure. If the vehicle has been standing for extended periods, inspect the brake discs for corrosion or binding, particularly in the corners where moisture and road salt can accelerate rusting. Additionally, verify that the brake fluid is free of contamination and that the brake pipes are clear of corrosion, ensuring no leaks or fluid loss. For the Isuzu Rodeo’s age and mileage, the buyer should also prioritise a visual and functional check of the tyre condition, focusing on sidewall perishing, which is common in older vehicles due to exposure to UV light and environmental elements. Tyres worn close to the legal limit or showing edge wear may indicate misalignment or suspension issues that have been present but not fully rectified. The battery should be tested for voltage output and corrosion on terminals, as prolonged idling or high-mileage usage can strain the electrical system. Fluid levels—particularly the engine oil, coolant, and brake fluid—should be checked and topped up if necessary, with a reminder that fluids degrade over time, even if the vehicle is not driven frequently. Lastly, verify that the service history is up to date, particularly for the wheel bearing replacements and suspension component inspections that are likely due given the advisories. If the vehicle has been maintained sporadically, a comprehensive mechanical inspection by a qualified technician is strongly recommended to address the unresolved suspension and brake system concerns before purchase.
