2005 Chrysler-Jeep Grand Cherokee 3.0L Diesel · AF05 FDZ

The 2021‑12‑14 MOT at 185,989 miles resulted in a pass, confirming that the vehicle currently meets the minimum roadworthiness criteria despite a litany of recorded defects. The record shows a clear improvement from the 2019 failure, where serious brake and exhaust deficiencies were noted, to the 2020 and 2021 passes, indicating that previous owners have addressed many of the most critical issues. However, recurring suspension wear, persistent oil leakage and ongoing chassis corrosion suggest that the underlying maintenance pattern remains uneven rather than uniformly improving. With a current odometer reading of 185,989 miles and an age of approximately 21 years, the average annual mileage of 8,857 miles is close to the typical range for a vehicle of this vintage. Nonetheless, the mileage history reveals irregularities: a jump from 267,154 miles in April 2018 to 174,528 miles in April 2019, and a subsequent rise of only 11,461 miles over the next two years, implying possible mileage correction or inconsistent reporting. Apart from these outliers, the incremental increase from 2019 to 2021 is modest, supporting the view that the vehicle has been used at a steady, moderate pace since the major service events. The most frequent mechanical concerns documented are suspension component wear – specifically worn arm pins, bushings and ball joints on both sides – and extensive corrosion of coil springs and under‑body structures, which have appeared in every test since 2015. Repeated reports of rear service brake binding, parking brake inefficiency and service brake imbalance point to persistent brake system degradation, while the severe oil leak recorded in 2019 and again in 2021 indicates a continuing engine sealing problem. The severely deteriorated drive‑shaft CV joint boot and the presence of rust on the rear axle further signal areas that merit close inspection. A prospective buyer should therefore prioritize a physical examination of the suspension geometry, checking for excessive play in arm pins, bushings and ball joints, and verify the condition of the coil springs and under‑body rust. The brake system must be tested for binding, pad thickness and disc integrity, and the parking brake should be confirmed as fully functional. Attention should also be given to the oil leak source, the health of the drive‑shaft CV joint boot, and the overall structural soundness of the chassis, as these recurring faults represent the most likely sources of future failure.
