2009 MAZDA 51.8L Petrol

The vehicle shows a history of recurring mechanical and structural issues that suggest reactive rather than preventative maintenance. The most recent MOT test on 24 February 2026 at 107,551 miles passed, but it followed a failure just eleven days prior. That failure highlighted critical concerns including an inoperative engine management light, a lack of visible coolant, and a split nearside front drive shaft CV boot. While these specific items were addressed for the pass, the record reveals persistent heavy corrosion on the rear sub-frame, anti-roll bar, and control arms, which have been flagged across multiple years without resolution. At 107,551 miles over 17 years, the Mazda 5 covers an average of approximately 6,300 miles per year, which is typical for a vehicle of this age. However, the inspection data indicates significant wear on the braking system and suspension components. Between 2025 and 2026, the tester consistently noted pitted and scored brake discs on both front and rear, along with thinning rear pads. The recurring presence of heavy corrosion on the sub-frame suggests the vehicle has been exposed to harsh conditions or that the low annual mileage has not prevented the accumulation of surface and potentially structural degradation. A buyer should be wary of the structural integrity of the rear sub-frame and suspension mounting, as the tester has repeatedly identified these as badly corroded despite not yet failing. The failure regarding the engine management light in early 2026 indicates potential electrical or sensor faults that may not be fully diagnosed. Given the state of the brake discs and the age of the rubber components like the CV boots and bushes, a thorough physical inspection of the underbody is required to ensure the corrosion has not progressed beyond the point of economical repair.
