2022 Mercedes-Benz CLA 1.3L Petrol · ST22 KMG

Suspension wear dominates the MOT record, with a serious fluid leak on the off‑side rear shock absorber recorded in June 2025 and a near‑side front anti‑roll bar ball‑joint showing slight play in the latest June 2026 inspection, although the car cleared that test. The progression from a major rear‑suspension failure to a front‑suspension advisory suggests that the vehicle’s suspension components have been subjected to measurable stress and may be approaching the end of their service intervals. At roughly 43,750 miles over just under four years, the average annual mileage sits close to 11,000 mi, which is typical for a vehicle of this age. The MOT history shows no gaps, indicating the car has been presented for annual testing without prolonged off‑road periods. This mileage level places normal wear expectations on consumables such as tyres, brake pads and the suspension, but does not, on its own, point to accelerated degradation. For the rear shock absorber, look for a noticeable sag when the vehicle is stationary, uneven tyre wear on the rear axle, and any clunking or fluid stains under the rear wheels during a short drive over bumps. A leak often precedes loss of damping, which can cause reduced ride comfort and compromised handling, especially when cornering or braking. The front anti‑roll bar ball‑joint should be checked for excessive play by applying lateral force to the wheel while the steering is locked; audible knocking or a vague steering wander at low speeds can also indicate wear. Replacement of the ball‑joint or a full front suspension inspection may be required to restore precise steering response. Given the documented suspension issues, an independent mechanical inspection focused on the rear shock absorber and front anti‑roll bar assembly is advisable before finalising purchase. Verify that any remedial work has been carried out and obtain cost estimates for potential replacements, using those figures to negotiate a fair price that reflects the impending maintenance on the suspension system.
