2017 Mercedes-Benz GLA 2.1L Diesel · KY67 AEX

The 2017 GLA presents a mixed picture. Its maintenance trend is currently worsening. A clean record spanning three consecutive years from 2022 to 2024 was abruptly interrupted by a failure and a marginal pass in September 2025, both recorded on the same day at 56,357 miles. The vehicle is now 9 years old and its MOT history is current, with the most recent test conducted on 10 September 2025, roughly nine months before today's date of 17 June 2026. The immediate concern is the nearside front outer constant velocity boot, which was flagged as severely deteriorated with a tear at the clip during the September 2025 test. A torn CV boot allows grease to escape and contaminants to enter, risking joint failure and costly drivetrain repair if left unrectified. The vehicle also failed on both front anti-roll bar linkage ball joint dust covers, which no longer prevent dirt ingress. While the subsequent pass suggests these items were addressed, the simultaneous failure of multiple rubber dust covers points to an underlying pattern of perished protective components, likely age-related degradation across the front suspension. The mileage pattern is unremarkable and consistent with typical use. The vehicle accumulated 4,383 miles between the September 2022 test at 43,127 miles and the September 2023 test at 47,944 miles, then 4,021 miles between September 2023 and September 2024 at 51,965 miles. From September 2024 to September 2025, the mileage increased by 4,392 miles, maintaining an average of roughly 6,200 miles per year across its lifetime. There are no suspicious gaps or sudden spikes in accumulation, suggesting regular, steady use rather than prolonged standing or excessive mileage. The MOT record itself is complete and consistent, with annual tests filed without notable gaps. A buyer should focus the in-person inspection on the front suspension and drivetrain. The repeated failure of rubber dust covers on the anti-roll bar linkages and the CV boot suggests broader deterioration of protective boots and gaiters throughout the front end. Inspect all remaining constant velocity boots, track rod ends, and lower ball joints for splits, perishing, or contamination. Check the condition of the anti-roll bar linkages themselves, as worn ball joints may have been masked by replacing only the covers. Examine the underside for corrosion, particularly on subframes, suspension mounting points, and brake lines, as these can develop on a vehicle of this age even with average mileage. The nearside front brake caliper and disc should also be inspected, given that binding rear brakes are a common advisory on this platform and the front end has already shown wear-related faults. A road test should confirm smooth drivetrain operation with no clicking from the CV joints during tight turns.
