2019 Mercedes-Benz CLA 1.3L Petrol · SS07 MOL

Front-tyre structural failures and rapid wear on the inner edges have defined the MOT narrative of this 2019 Mercedes-Benz CLA, with two Dangerous defects recorded against the nearside and offside front tyres across the 2025 and 2026 tests. The August 2025 assessment produced both front tyres at the legal 2mm threshold with inner-edge wear, alongside a Dangerous failure for an offside front tyre with exposed ply or cords, yet the same date also carries a Pass, suggesting a same-day replacement and re-test. By 11 August 2026 the pattern recurred: the vehicle failed on a nearside front tyre bulge caused by structural separation in the outer sidewall, then passed with no defects recorded on the same date. While the test history contains no other advisories or failures, the recurrence of identical Dangerous tyre defects on consecutive annual tests points to either a chronic alignment or suspension geometry issue accelerating front-tyre shoulder wear, or a habitual pattern of running tyres beyond their serviceable life. With 99,107 miles accumulated over roughly seven years, this CLA has covered approximately 14,158 miles per year, which sits well above the national average for its age and points to consistent long-distance or commuter use rather than occasional leisure driving. There are no unusual gaps in the MOT testing record, and the mileage progression between tests is steady rather than erratic, suggesting the vehicle has remained in regular service throughout its life. Mechanically, this level of annual mileage places elevated demand on the braking system, front suspension components, clutch and dual-clutch mechatronics (where applicable), and drivetrain mounts, even where no defects have yet been recorded. Consumable wear items such as brake discs, pads, and tyres would be expected to require replacement more frequently than on a lower-mileage equivalent, and proactive inspection of these areas is therefore warranted regardless of what the MOT paperwork alone reveals. For a prospective buyer, the priority inspection area is the front axle geometry and its effect on tyre wear. The repeated inner-edge wear pattern on both front tyres, culminating in exposed cords and sidewall bulges, is symptomatic of either incorrect camber settings, worn front suspension bushes, displaced strut tops, or a bent component following an impact. On a test drive, listen for clonking or knocking noises from the front suspension over speed humps and uneven surfaces, and feel for vagueness in the steering, uneven steering self-centring, or a pull to one side under braking. A physical inspection of the front tyres for uneven shoulder wear relative to the centre tread, combined with a four-wheel alignment check, should be a non-negotiable condition of purchase. The braking system and general chassis condition also warrant close scrutiny given the mileage accumulation. Although no brake-related advisories appear in the MOT history, request an inspection of brake disc thickness, pad material remaining, and any binding or uneven wear on the front calipers, as high-mileage Mercedes front calipers are known to seize gradually. Check the underside for any signs of corrosion on the front subframe, brake pipes, and suspension arms, particularly given the vehicle's age. Finally, verify that the replacement tyres fitted at the most recent test are a matched pair of reputable brand, correctly sized to the manufacturer's specification, and confirm with the seller whether a four-wheel alignment was carried out following the repeated inner-edge wear findings, as this will be the single most important factor in preventing a recurrence of the Dangerous defects seen on the previous two MOT submissions.
