2019 Mazda CX-5 2.2L Diesel · DX69 FSJ

The latest DVSA MOT test for the 2019 Mazda CX-5 recorded a passing outcome on 2025-09-25, with two advisories related to corrosion in the rear suspension arms—both nearside and offside—classified as not seriously weakened under 5.3.3 (b) (i). These advisories indicate early-stage galvanic corrosion affecting the aluminium or steel components, which, while not immediately compromising structural integrity, signal ongoing exposure to moisture or poor drainage that could accelerate deterioration if left unaddressed. The absence of any failures or critical defects in the preceding three MOT tests—most recently on 2024-10-04—suggests a stable maintenance trend thus far, though the recurring advisories warrant closer attention to prevent progression. The vehicle’s consistent passing history implies that any underlying issues have been managed effectively, but the suspension arms should be monitored for signs of further corrosion or fatigue, particularly if the car is driven regularly or stored in damp conditions. The recorded mileage of 39,703 miles for a seven-year-old CX-5 represents a relatively low annual usage rate of approximately 5,672 miles per year, which is notably below the average for its age and class. Lower mileage can result from lighter operational demands, extended periods of inactivity, or infrequent use, all of which may contribute to wear patterns that differ from those seen in higher-mileage vehicles. However, prolonged standing—especially in a damp environment—can accelerate corrosion in suspension components, brakes, and underbody areas, as evidenced by the recent MOT advisories. Additionally, low mileage might mask wear in consumables like brake pads, clutch components, or fluid degradation over time, since these are less frequently replenished. The absence of rapid mileage accumulation does not inherently guarantee mechanical soundness, but it does suggest that wear has not been exacerbated by heavy or aggressive driving. For the prospective buyer, the most critical areas to inspect during a physical examination are the rear suspension arms, which show signs of corrosion. Visually check for further progression of pitting, flaking, or cracks in the aluminium or steel, and listen for unusual clunking or rattling when the vehicle is driven over bumps or uneven surfaces—symptoms that may indicate loose or weakened suspension components. The offside rear tyre’s minor cut, though not severe, should be monitored for signs of cord damage or further deterioration, as this could compromise tyre integrity over time. Given the advisories, a thorough inspection of the rear suspension bushings and strut mounts is also advisable, as corrosion can lead to binding or excessive play in these components, contributing to ride quality issues or premature wear. Beyond the suspension, the vehicle’s age and low mileage make it prudent to focus on age-related checks that may not be apparent from mileage alone. Inspect the tyres for sidewall perishing or cracking, which can weaken their structural integrity and reduce safety, particularly if the vehicle has been stored for extended periods without use. Check the 12V battery for signs of corrosion at the terminals and test its charge capacity, as older batteries may struggle under low-demand conditions. The brake system should be examined for signs of corrosion on the discs or binding calipers, which can occur when the vehicle stands for long periods without braking activity. Additionally, since the vehicle’s fluids—oil, coolant, and brake fluid—are subject to degradation over time regardless of mileage, a visual inspection for contamination or sludge in the dipstick tube, radiator, or brake master cylinder reservoir is recommended. Finally, verify that service records are up to date, particularly for fluid changes and lubrication, as the 2019 model year may have specific intervals for time-based servicing that have not been documented.
