2016 Mercedes-Benz A-Class 2.1L Diesel · EX66 RRY

A pattern of structural tyre failures and emerging brake wear defines the recent mechanical history of this vehicle. While it passed its latest inspection on 9 January 2026, this followed a dangerous failure due to a bulging offside rear tyre, echoing a similar dangerous failure in January 2024 involving the offside front tyre. The record shows a transition from clean passes between 2021 and 2023 to a more problematic trend involving tyre integrity and, most recently, wear on both front and rear brake discs. With 78,450 miles recorded over approximately ten years, the vehicle has averaged around 7,845 miles per year, which is typical for its age. This consistent usage pattern suggests a steady accumulation of wear on drivetrain and suspension components rather than the risks associated with prolonged standing or excessive high-mileage stress. However, the recurrence of structural tyre failures despite average mileage is a specific point of concern regarding the vehicle's interaction with road surfaces or the quality of replacements used. Particular attention must be paid to the braking system and suspension linkages during a physical inspection. The January 2026 advisories for worn front and rear brake discs suggest these components are approaching the end of their service life. On a test drive, feel for any pedal judder or steering wheel vibration under braking, which can indicate disc wear or warping. Additionally, the 2024 failure of the nearside front anti-roll bar linkage ball joint dust cover and reported play in the offside linkage should be verified. Listen for knocking or clicking sounds when driving over speed bumps or navigating uneven road surfaces, as these are typical symptoms of worn suspension linkages. A thorough visual inspection of all four tyre sidewalls is essential given the history of structural bulges on both the front and rear offside tyres. Check for any irregular wear patterns or protrusions that could indicate further structural compromise. Because the nearside rear tyre was flagged as going out of shape on its inner edge in the most recent test, verify the current alignment and tread depth of this specific tyre to ensure the issue has been rectified.
