2021 Mercedes-Benz GLE 2.9L Diesel · KA17 TAL

A clean and commendably sparse MOT record defines this 2021 GLE, with the most recent test on 4 September 2026 returning a pass and no advisories whatsoever, marking a notable improvement over the previous two examinations. The 2024 test flagged both rear tyres as worn close to the legal limit, while the 2025 pass carried a single advisory for a nail in the nearside rear tyre. Each of these advisories was relatively minor and tyre-related rather than structural or mechanical, and the absence of any brake, suspension, exhaust, or corrosion advisories across three consecutive tests is a positive indicator for a vehicle of this size and weight. The progression from dual tyre advisories, to a single minor tyre advisory, to a fully clear pass suggests either attentive remedial maintenance or simply that fresh tyres were fitted after the 2024 test. With 59,431 miles accumulated over approximately five years, this GLE has covered roughly 11,886 miles annually, which sits comfortably within the typical usage bracket for a premium SUV of its age. There are no unexplained spikes or drops in mileage between the recorded tests, and no multi-year gaps that would suggest the vehicle has been laid up, which removes the usual concerns around seized brakes, perished rubber components, or stale fluids associated with long-standing cars. Consistent annual mileage of this magnitude means the drivetrain, suspension, and braking components have been exercised regularly, which is generally beneficial for keeping seals lubricated, preventing moisture accumulation in the brake system, and avoiding flat spots on tyres. For a prospective buyer, the primary mechanical items to evaluate are the components most heavily loaded on a heavy SUV driven at this mileage band: the front and rear suspension, the brake system, and the tyres themselves. Although no suspension advisories have been recorded, it is worth inspecting the front lower control arm bushes, anti-roll bar drop links, and coil springs for any perishing or sagging, particularly given the GLE's mass. On a test drive, listen for clonking noises from the front end over speed bumps or uneven surfaces, which would suggest worn bushes or top mount bearings. Pay particular attention to the rear suspension, as the 2024 advisories indicate the rear tyres were being worn on their edges, which can sometimes point to a slight alignment issue, a weakening rear spring, or a worn thrust arm or trailing arm bush allowing geometry to drift. The braking system should be evaluated carefully despite its clean MOT record, as the GLE's considerable weight places significant demand on the discs and pads, particularly under towing or motorway driving conditions. On test, feel for any judder through the steering wheel or brake pedal under firm stopping, which can indicate warped front discs, and listen for any grinding or scraping that might suggest worn pads contacting the discs. The tyres themselves should be inspected for even tread wear across the axle; if the rear tyres are again showing asymmetric inner or outer edge wear, this could confirm an underlying geometry or suspension component issue rather than simple tyre ageing. Finally, although no corrosion advisories have been raised, a careful visual check of the underbody, subframe mounting points, and brake pipes is advisable given the vehicle's age and exposure to winter road conditions, and a thorough inspection of all fluid levels and any signs of oil seepage around the engine and transmission areas would be prudent given the mileage.
