2014 Jeep Grand Cherokee 3.0L Diesel · WM14 DMX

The most recent DVSA MOT test on this 2014 Jeep Grand Cherokee, conducted on 21 August 2026, resulted in a Pass, though it was accompanied by an advisory concerning the front brake disc being worn, pitted or scored, although not judged seriously weakened at the time of inspection. Reviewing the broader test history reveals a generally stable pattern of roadworthiness, with the vehicle passing successive annual tests on multiple occasions without any recorded defects, particularly during the 2021 to 2023 period. However, there is a recurring theme relating to headlamp presentation, with failures and minor defects recorded in both 2021 and 2025 regarding headlamp aim and the headlamp cleaning device. While the most recent test outcome itself does not suggest acute deterioration, the advisory now recorded on the front brake discs warrants close attention, as brake-related wear items on a vehicle of this age and mileage are typically progressive and may soon require rectification. With recorded mileage standing at 79,886 miles over approximately 12 years, the vehicle has accumulated roughly 6,657 miles annually, which represents a broadly typical usage rate for its age. There are no significant gaps in the MOT record suggesting extended periods off the road, and the steady accumulation of mileage indicates a vehicle that has been used consistently rather than one that has stood idle for prolonged periods. This continuous usage pattern is generally beneficial for mechanical components, as regular operation helps prevent issues associated with standing, such as brake seizure, fluid degradation, and corrosion of underbody components. The mileage itself is moderate for the platform, meaning that while major driveline components such as the engine, transmission, and drivetrain should retain substantial service life, normal consumable replacement schedules remain highly relevant. Given the advisory concerning the front brake discs, a prospective buyer should prioritise a thorough inspection of the braking system. Surface pitting and scoring on brake discs typically develop over time and are exacerbated by infrequent heavy braking, corrosion, or worn brake pads. On a test drive, any signs of brake shudder through the steering wheel or pedal under firm application would suggest the discs have worn beyond their service limit and require machining or replacement. Brake pedal feel should be firm and progressive, without excessive travel or sponginess, which might also indicate the need for fluid renewal. It would be prudent to physically inspect disc thickness, check pad material remaining, and ensure the calipers are sliding freely without binding, as binding calipers can accelerate disc wear unevenly. Additionally, listen for any grinding or squealing noises during low-speed manoeuvres, which can be indicative of pads nearing the end of their service life. Beyond the advisory, the recurring headlamp-related issues should be investigated. The headlamp cleaning device defect recorded in 2021 and the headlamp aim failure in 2025 suggest possible electrical or adjustment concerns. A buyer should verify that both headlamps are correctly aimed, that the headlamp washers are operational, and that there are no underlying wiring faults affecting the lighting system. Given the vehicle's age, further age-related checks are strongly advised regardless of the MOT record. Tyres should be examined for sidewall cracking or perishing caused by UV exposure, even if tread depth remains legal, as twelve-year-old rubber compounds can degrade significantly. The 12V battery should be load-tested, as batteries of this vintage frequently fail without warning. Brake fluid, coolant, and transmission fluid should be considered for renewal based on calendar age rather than purely mileage, and a compression test or diagnostic scan would be wise to confirm the health of the engine and electronic control units. Finally, the underbody and suspension components, including coil springs, bushes, and anti-roll bar links, should be raised and inspected for corrosion or wear consistent with the recorded mileage and age.
