2019 Mercedes-Benz GLA 1.6L Petrol · CP68 PXV

The 2019 Mercedes-Benz GLA presents a stable, largely unremarkable roadworthiness record across five consecutive MOT passes, though a recurring brake disc advisory warrants closer scrutiny. In the most recent test on 25 February 2026 at 5,361 miles, the tester flagged both rear brake discs as worn, pitted, or scored but not seriously weakened. This is not a new problem. The same rear brake disc advisory appeared in February 2023 at 1,288 miles and again in February 2022 at just 805 miles. Front brake discs were also flagged in the 2023 test. The fact that these advisories have persisted across multiple annual tests spanning over four years suggests the discs have been in a degraded state for a considerable period rather than representing a sudden failure. The vehicle has not failed an MOT on brake-related defects, but the pattern indicates the braking system has received only baseline attention. The mileage profile is exceptionally low for a seven-year-old vehicle. The recorded readings show 805 miles in February 2022, 1,288 in February 2023, 1,833 in February 2024, 2,412 in February 2025, and 5,361 in February 2026. That final jump of 2,949 miles in a single year is notably higher than the previous annual increments of around 400 to 600 miles. The overall average sits at roughly 766 miles per year, which is well below the UK typical annual mileage of approximately 7,900 miles. Prolonged low use can itself cause issues. Brake discs that sit stationary or see minimal heat cycling are prone to surface corrosion and pitting, which aligns precisely with the recurring advisory pattern observed here. Tyres on low-mileage vehicles can also develop flat spots or sidewall degradation from standing, even when tread depth appears adequate. Prospective buyers should inspect the braking system carefully. Request a detailed look at all four brake discs for scoring depth and lip wear, and check the condition of the brake pads, which may have corroded backing plates or uneven contact surfaces from prolonged light use. The engine covers and undertrays noted as obscuring components in the 2022 and 2023 tests should be removed to allow a proper inspection of the engine bay, suspension mounts, and subframe for corrosion or fluid leaks. Given the extremely low mileage and the sudden increase in use during 2025 and early 2026, examine the tyres for age-related cracking and confirm their manufacture date codes, as rubber deteriorates with time regardless of tread. A pre-purchase inspection focusing on these areas will confirm whether the vehicle's light use has preserved it or quietly allowed deterioration.
