2015 Mazda Cx-3 2.0L Petrol · DF65 MKM

The 2015 Mazda CX-3 holds a valid MOT following its March 2026 pass at 107,776 miles, yet the maintenance trend is not reassuring. The most recent test flagged both rear tyres worn close to the legal limit and perishing, alongside an advisory for all brake pipes being corroded and covered in grease. A vehicle passing with tyres already at the wear threshold suggests the previous owner deferred basic consumable replacements. The recurring brake pipe corrosion advisory, now spanning multiple years, indicates a persistent issue rather than a one-off defect. Mileage accumulation sits at roughly 9,800 miles per year, which is typical for an eleven-year-old vehicle. The record shows a notable jump of approximately 14,400 miles between March 2025 and March 2026, a sharp increase compared to the steady 5,000 to 6,000 miles per year observed between 2023 and 2025. This recent surge in usage could accelerate wear on suspension bushes, brake discs, and drivetrain components that were previously seeing lighter use. The repeated identification of corroded brake pipes coated in grease across the 2024, 2025, and 2026 tests demands a thorough underbody inspection. A buyer should have a mechanic examine the full length of the braking system for structural integrity, paying close attention to the hard lines and flexible hoses for any signs of pitting or active leaks. The grease covering may be masking the true extent of the corrosion. Tyre condition also warrants direct scrutiny. The record shows tyres repeatedly wearing unevenly and perishing prematurely, which can point to neglected wheel alignment or suspension issues. A physical check of the inner sidewalls, tread depth across all four tyres, and the condition of the suspension bushes and coil springs is strongly advised before purchase.
