2019 Mercedes-Benz GLC 2.1L Diesel · AD14 ANA

Tyre wear has been the most persistent mechanical theme, with rear tyres flagged as dangerously below the 1.6 mm minimum in the 2023 failure and a succession of “worn close to legal limit” advisories on all four corners in the subsequent years. The 2026 MOT recorded a clean pass with no defects, indicating that the immediate safety‑critical issues identified in 2023 have been remedied, yet the continued presence of edge‑wear advisories suggests the tyre set is approaching the end of its service life and will likely need replacement soon. At 55,419 mi the vehicle averages roughly 7,900 mi per annum, a mileage rate that sits comfortably within normal usage for a seven‑year‑old executive SUV. The MOT history shows annual testing with no prolonged gaps, implying consistent road exposure rather than periods of storage. This steady accumulation translates to moderate wear on consumables such as tyres, brake pads and suspension components, but does not alone indicate accelerated deterioration of major drivetrain or structural elements. Prospective buyers should inspect the tyre tread on all four wheels, measuring depth across the centre and edges to confirm uniform wear and to verify that the tyres meet the legal minimum. While driving, listen for any thumping or knocking over bumps that could reveal the slight play noted on the off‑side front lower suspension arm ball‑joint, and assess steering feel for any looseness or wandering. The rear brake discs were previously reported as lipped and the pads as thin; a firm, vibration‑free pedal under moderate braking and the absence of squeal or grinding will be key indicators that the braking system has been serviced or is still within acceptable limits. Finally, confirm that the registration plate lamp is operational and that all other exterior lights illuminate correctly, as the 2023 failure highlighted an inoperative lamp. Given the tyre wear trend, budgeting for a full set of tyres and a thorough brake inspection is prudent. A qualified mechanic should also re‑examine the front lower suspension arm and rear brake discs to ensure any residual play or wear has been addressed before finalising the purchase.
