2018 Jeep Grand Cherokee 3.0L Diesel · OY18 ERK

The 2018 Jeep Grand Cherokee presents a stable and improving maintenance trend, culminating in a fully clean MOT pass on 22 May 2026 at 90,042 miles with zero defects recorded. This is a significant improvement over the preceding test cycle, where the vehicle failed on 27 May 2025 at 75,424 miles due to excessively worn nearside and offside front lower suspension arm ball joints. The failure was addressed before the June 2025 retest, which passed cleanly at 75,429 miles, indicating the previous owner corrected the defect promptly rather than deferring it. The subsequent 2026 test, conducted just under a month ago, shows no new advisories or failures, suggesting the vehicle is currently in sound mechanical order with no outstanding defects. The mileage accumulation of approximately 11,255 miles per year is typical for a vehicle of this age and reflects consistent use rather than prolonged standing or unusually heavy wear. The record shows a clear progression from 59,447 miles in July 2023 to 71,125 miles in July 2024, then to 75,429 miles by June 2025, and finally 90,042 miles in May 2026. There are no suspicious gaps or sudden jumps in the odometer readings, and the MOT history aligns well with the recorded mileage, reducing the likelihood of clocking or extended periods of neglect. The data set is relatively sparse with only five tests over three years, but each entry is consistent and verifiable. Buyers should pay particular attention to the front suspension components during any in-person inspection. The May 2025 failure for worn lower suspension arm ball joints at just over 75,000 miles raises a question about component longevity, potentially pointing to driving conditions or earlier maintenance gaps. Although the defect was rectified, the relatively early wear suggests the front end should be thoroughly checked for play, knocking, or uneven tyre wear. The rear braking system also warrants close scrutiny. In July 2024, the tester flagged both rear brake pads wearing thin and both rear brake discs showing wear, pitting, or scoring. While the discs were not deemed seriously weakened at that time, the combined wear on pads and discs at around 71,000 miles indicates the rear braking circuit has seen meaningful use. A buyer should inspect the remaining pad material and disc surface condition, as replacement may be approaching given the current 90,042-mile figure. The nearside front tyre noted as worn close to the legal limit in July 2024 is a consumable item and not a structural concern, but its appearance on the record alongside rear brake wear suggests the previous owner may have allowed basic maintenance items to deteriorate before addressing them. Beyond the documented defects, any inspection should include a thorough underbody examination for corrosion, particularly around suspension mounting points, subframes, and brake lines, as these are common long-term concerns on this platform. The clean 2026 result is encouraging, but the earlier suspension failure and combined brake wear indicate a vehicle that has required attentive upkeep rather than one that has been entirely trouble-free.
