2018 Jeep Compass 2.0L Diesel · KS18 AAY

A clear and consistent mechanical theme emerges from the MOT history of this 2018 Jeep Compass: progressive suspension bush wear. Across the last three consecutive tests, advisories relating to suspension arm pins and bushes have accumulated, with the February 2026 test recording five advisories in total, the highest number in the recorded history. The offside rear trailing arm bush was first flagged in 2025, then appeared again in 2026 alongside the nearside rear trailing arm and the nearside front wishbone rear bush, suggesting that the wear is advancing rather than stabilising. The 2026 test was a pass with no failures or dangerous defects recorded, and the trend remains one of advisory-level deterioration rather than outright test failure, but the pattern is worth taking seriously before purchase. With 53,412 miles recorded over approximately eight years, the annual accumulation is around 6,676 miles, which sits broadly in line with typical usage for the age and type of vehicle. There are no significant gaps in testing that would suggest extended periods off the road, and the mileage progression between tests is steady rather than erratic, indicating consistent use. The 2022 test stands out slightly as it carried four tyre-related advisories, suggesting a period of faster road use or uneven tyre rotation, though no suspension or brake wear was recorded at that point. Since 2022, the wear pattern has shifted from tyres to suspension and brake components, which is consistent with the natural progression of mechanical ageing in a vehicle of this age and mileage. For a prospective buyer, the priority on inspection should be the rear suspension, particularly the trailing arm bushes that have now been flagged on both sides. On a test drive, listen for clonking or knocking noises from the rear suspension over speed humps, uneven road surfaces, and during direction changes, and feel for any vagueness or delay in the rear end settling after a bump. With the vehicle raised or on a ramp, the trailing arm bushes should be physically checked for cracking, splitting, or excessive play, as advisory thresholds can still mask movement that affects handling. The nearside front wishbone rear bush should also be inspected for similar deterioration. The brake discs noted as worn, pitted, or scored on both rear sides in the 2026 test warrant close attention as well. Under heavy braking from speed, listen for any grinding, vibration through the brake pedal, or judder that could indicate the corrosion has progressed since the test was carried out. The rear brake discs may now be approaching the minimum permissible thickness and could require replacement, particularly if a garage measures them close to the discard limit. Beyond these flagged items, a general check of all fluid levels, a thorough inspection underneath for any oil leaks or corrosion on subframe and suspension mounting points, and confirmation that all tyres are within legal tread depth will round out a sensible pre-purchase evaluation.
