2013 Mazda 6 2.2L Diesel · WM63 LGN

The 2013 Mazda 6 presents a mixed maintenance picture. The most recent test on 11 December 2025 at 131,063 miles resulted in a pass, but only after a failure on the same day for a worn offside front suspension arm ball joint, degraded anti-roll bar linkage dust covers, borderline front tyres, and a parking brake efficiency reading below 50 per cent of the required value. That same-day retest passing suggests the immediate safety-critical items were addressed, yet the pattern across the last two years reveals a recurring cycle of wear and correction rather than consistent preventative upkeep. The trend is neither clearly worsening nor fully resolving; it sits in a reactive middle ground where components are replaced or adjusted only when they fail the test threshold. Mileage accumulation is broadly typical for a 13-year-old vehicle, averaging roughly 10,082 miles per year. The record shows 118,133 miles in December 2023, 124,807 miles in November 2024, and 131,063 miles in December 2025, indicating a steady annual increase of around 6,700 to 6,900 miles. There are no alarming gaps or sudden jumps in the odometer readings, and the annual test interval appears consistent, suggesting the car has been in regular use rather than standing idle for extended periods. The recurring fault pattern centres on front suspension and braking components. The offside front suspension arm ball joint was flagged as excessively worn in both the November 2024 and December 2025 failures, indicating either a replacement that has not lasted or a persistent issue with that corner of the vehicle. A corroded nearside front brake pipe appeared in the November 2024 failure, and front brake fluctuation advisories surfaced in both 2024 tests. Buyers should inspect the front suspension bushes, ball joints, and anti-roll bar links for play or deterioration, paying close attention to the offside front area. Brake pipe condition along the underside and around the front arches warrants a thorough check for corrosion, particularly if the car has been used on salted roads. Tyre wear has appeared as an advisory in the most recent two tests, with both front tyres noted as worn close to the legal limit and worn on the edge. Edge wear typically points to tracking or alignment issues rather than simple underinflation. A buyer should verify wheel alignment settings and inspect the inner sidewalls of all four tyres. The parking brake inefficiency recorded in the December 2025 failure also merits attention, as it could indicate stretched cables, worn rear brake shoes or pads, or a handbrake mechanism requiring adjustment. A physical inspection of the rear braking system and a functional parking brake test on an incline would provide clarity before purchase.
