2011 Mazda CX9 3.8L Petrol · EY60 EEW

This 2011 Mazda CX9 presents a worsening maintenance trend, with the most recent MOT record raising significant mechanical concerns. The November 2023 test at 150,510 miles passed only after the vehicle failed severely just seven days earlier on October 26 at 150,503 miles. The earlier failure cited major braking defects, including service brake efficiency below requirements and parking brake efficiency less than 50 percent of the required value, alongside a complete lack of recorded effort at a wheel on the single-line secondary braking system. While the car scraped a pass a week later, the sudden emergence of multiple serious brake failures points to neglected upkeep rather than proactive maintenance. Mileage accumulation is consistent with the vehicle's age, averaging roughly 10,000 miles annually over its 15-year lifespan. The odometer climbed from 130,818 miles in October 2021 to 150,510 miles in November 2023, showing steady use rather than prolonged standing or erratic mileage spikes. The MOT history is relatively sparse regarding advisory items prior to 2023, though this clean run was broken by recurring minor issues that escalated into major failures. A loose battery carrier flagged in October 2021, for instance, indicates a pattern of basic checks being skipped. A buyer must prioritize a thorough inspection of the braking system and steering components before purchase. The parking brake failed on efficiency grounds twice, first in October 2021 at 130,817 miles and again in October 2023, suggesting worn rear shoes, binding calipers, or severely corroded brake discs that were merely adjusted to pass rather than properly repaired. The service brake failure in October 2023 demands immediate verification of disc thickness, pad material, and hydraulic integrity. The offside front power steering ram also requires close evaluation; the tester noted slight seepage from a joint and a weeping rack seal in October 2023, which will inevitably worsen and require replacement of the steering rack or ram assembly. The illuminated tyre pressure monitoring system light warrants a diagnostic check to rule out faulty wheel sensors.
