2015 Mercedes-Benz GLA 2.1L Diesel · SY65 PFF

A fractured offside rear coil spring and a significantly worn offside rear brake disc represent the two most consequential defects in this Mercedes-Benz GLA's testing history, both of which were serious enough to record as failures rather than mere advisories. The most recent event, a pass dated 24 February 2026, came immediately after a failure on the day prior caused by the fractured rear coil spring, while the brake disc concern was carried forward as an advisory rather than reclassified. Earlier, in February 2023, the vehicle failed on headlamp aim being too low on both sides, accompanied by a major defect for an offside rear brake disc that was judged significantly and obviously worn. The presence of two major defects across the recorded tests, one relating to suspension integrity and one to braking component condition, suggests that wear items on this GLA are not being addressed until they cross the threshold from advisory to dangerous, which a buyer should weigh carefully. With 122,961 miles recorded over approximately eleven years, this vehicle has accumulated roughly 11,178 miles annually, placing it broadly within the expected band for its age. The testing cadence is reasonably consistent, with annual entries between 2021 and 2026 and no extended absences that would indicate long periods off the road. A single brief mileage gap between September 2022 and January 2024 is visible, though this likely reflects a timing overlap between tests rather than storage, and the recorded accumulation remains plausible given the vehicle's age and class. Given the documented brake disc wear on both front and rear axles, particular attention should be paid to braking performance during a test drive. The front discs were noted as pitted and scored on the most recent test, so any pulsation through the brake pedal, vibration under heavy braking, or inconsistent stopping effort would suggest the discs have deteriorated beyond the advisory threshold. Similarly, the 2023 major defect on the offside rear brake disc indicates the rear braking surface has been a chronic wear point, so a binding caliper or uneven handbrake pull to one side on a slope would warrant further inspection. Given that fractured coil springs have been recorded on this chassis, listen for clonking noises or a noticeably harsher ride over undulations, particularly over speed bumps or uneven surfaces, and inspect the ride height at the rear for any sagging that could indicate a second spring on the verge of failure. The tyre advisories recorded in 2023 and 2024, covering both front and rear axles, point to a pattern of shoulder wear and sidewall deterioration rather than simple age-related perishing. When inspecting the vehicle, examine the inner and outer edges of all four tyres for uneven wear, as consistent edge wear often indicates incorrect alignment or worn suspension linkages, both of which are plausible given the mileage. A road test over uneven surfaces should reveal any knocking from the front suspension, while a steering pull to one side would suggest geometry issues. Finally, although the lamp aim failures from 2023 were straightforward, headlamp adjustment mechanisms on the GLA can drift over time, so verifying both low beam patterns against a flat surface before purchase is prudent to avoid a repeat advisory or failure at the next test.
