2020 Mercedes-Benz GLC 1.9L Diesel · LM70 EFX

The vehicle is currently roadworthy, but the maintenance history shows a worsening trend regarding reactive rather than proactive care. While the latest test in October 2025 at 20,868 miles was a pass, it followed a failure just four days prior at 20,799 miles. This failure identified significant mechanical issues including worn offside rear brake pads and pitted or scored brake discs, indicating that the braking system was only addressed once it reached a point of failure rather than being maintained during service intervals. At 20,868 miles, this six-year-old GLC reflects low mileage, averaging approximately 3,478 miles per year. This low usage suggests light road travel, but the data reveals issues associated with vehicles potentially sitting for stationary. Between September 2023 at 12,126 miles and September 2024 at 16,071 miles, the car covered only 4,045 miles, yet the tester began flagging concerns with tyre perishing and uneven wear, which often stems from flat-spotting or alignment issues rather than high mileage. A buyer must conduct a thorough physical inspection of the braking assembly and tyre condition. The recurring reports of tyres worn to the legal limit or perishing across the 2024 and 2025 tests suggest a lack of attention to consumable upkeep or a lingering geometry fault. Furthermore, the 2025 failure for pitted rear discs confirms that the brakes may have suffered from corrosion due to low use. Ensure the offside rear pads and discs were replaced as a pair, and verify that the child seat which previously obstructed inspections no longer masks potential seatbelt defects.
