2019 Mercedes-Benz GLC 4.0L Petrol · F4 NKF

A pattern of tyre wear and a lingering exhaust‑mount issue defines this GLC’s MOT history – a dangerous failure for the nearside rear tyre in March 2024 forced a re‑test, after which the car cleared with only advisories for the same rear‑exhaust clamp and a marginal parking‑brake efficiency. The most recent 2025‑12‑12 test recorded a clean pass, indicating that the immediate safety concerns have been addressed, yet the repeat advisory on the rear‑exhaust clamp signals that the fix may have been provisional rather than a permanent replacement. At 60,152 mi over roughly seven years the average annual mileage sits near 8,600 mi, which aligns with typical usage for a premium SUV. The MOT schedule shows regular annual testing, with a brief gap in early 2024 when the vehicle was tested twice within a week – a rapid response to the tyre failure. This mileage level suggests that consumables such as tyres, brakes and suspension components are approaching the point where normal wear‑related replacement is expected, especially given the documented uneven tyre wear. Prospective buyers should give the rear‑exhaust mounting area a thorough inspection for any cracked or missing clamp, rattles, or exhaust leaks at low revs and when the vehicle is stationary. The parking‑brake lever should hold firmly without excessive travel; a slip or soft feel could indicate the adjustment noted in the advisory still needs correction. The rear prop‑shaft flexible coupling, flagged in 2022, warrants a listening test under acceleration for whine or vibration and a visual check for oil seepage around the differential housing. All four tyres must be measured for tread depth and examined for sidewall cuts or edge wear, as the nearside rear tyre previously fell below the legal minimum and the front tyres were flagged for edge wear and a shallow cut. Uneven wear may point to alignment or suspension issues, so a test‑drive should include a straight‑line run to detect any pull, and a ride over bumps to feel for knocking in the suspension bushes or coil springs. Brake pedal response should be firm and without pulsation, confirming that the parking‑brake efficiency issue has been fully resolved.
