2012 Jeep Grand Cherokee 3.0L Diesel · OY12 ABK

The most recent DVSA MOT test on 20 December 2021 resulted in a PASS, although the same date also shows a FAIL entry containing a PRS (dangerous) defect for a malfunctioning Tyre Pressure Monitoring System (TPMS) alongside the same advisory items recorded at the pass. Because the TPMS is a Class A mandatory safety item, the vehicle would not have been driven legally until rectified, and any prospective buyer should obtain documentary proof that a replacement sensor, reset, or repair was carried out and subsequently verified at a follow-up test. The other items recorded are advisory or minor in nature and do not constitute failures, but they represent accumulating wear points. The pattern across the test history suggests a vehicle that has been maintained broadly to a passable standard but is showing the kind of age-related deterioration typical of a fourteen-year-old SUV, with several advisories that warrant close physical inspection before purchase. With a recorded mileage of 97,155 miles over approximately fourteen years, this Grand Cherokee has averaged around 6,940 miles annually, which is broadly typical for its age and consistent with mixed private and light utility use. There is no evidence within the MOT record of unusually high annual accumulation that would indicate sustained motorway mileage, nor are there extended gaps suggesting long periods of standing. This places the vehicle in a moderate wear bracket, where service items such as timing chains, suspension bushes, and drivetrain mounts are approaching or past their second-cycle replacement point. Buyers should confirm that the recorded mileage is supported by a continuous service history with corresponding invoiced work, as odometer discrepancies on vehicles of this age and complexity are not uncommon. The advisory relating to all brake discs being worn, pitted, or scored is mechanically significant and should not be overlooked. Pitting of this nature typically progresses from surface oxidation to measurable lip formation and eventual brake shudder or reduced efficiency under heavy use, particularly when descending gradients or towing. On a test drive, listen for any pulsation through the brake pedal, check for pulling to one side under firm application, and inspect the discs directly through the wheel spokes for a sharp inner and outer edge lip, visible ridging, or corrosion that has not yet polished away. Given the advisories were recorded nearly five years ago at the latest test, it is reasonable to assume the discs may now require replacement, particularly if the vehicle has been used in environments where winter road salt accelerates corrosion. The nearside daytime running light failure is a simple electrical item, but its persistence across both entries suggests the underlying bulb holder, wiring, or LED module may need attention, which is worth factoring into any negotiation. The offside steering rack advisory noting a light mist of oil is a particularly important point for a buyer, as steering rack seepage on the WK2 Grand Cherokee is a known wear pattern that can progress from a harmless mist to active leakage. Left unchecked, this can lead to reduced hydraulic assistance, contamination of the lower ball joint and suspension components with hydraulic fluid, and ultimately rack replacement. On a test drive, listen for any whining or groaning from the steering during low-speed manoeuvres and check for fluid residue on the offside inner driveshaft gaiter, subframe, or lower suspension arm. Additionally, for a vehicle of this age and mileage, calendar-based servicing is critical regardless of the odometer reading: the twelve-volt battery should be load tested, coolant and brake fluid should be replaced on their time-based schedules, the transfer case and differentials should have had recent fluid changes, and the tyres, while possibly legal on tread depth, should be examined for sidewall perishing and cracking given their age. Finally, the offside windscreen chip and the TPMS issue should both be verified as resolved, and a fresh diagnostic scan for any stored fault codes in the body, transmission, and emissions control modules would be prudent given the vehicle's age.
