2018 Mercedes-Benz GLE 3.0L Diesel · GC18 DPY

The latest DVSA MOT test on the 2018 Mercedes-Benz GLE recorded a passing outcome on 2026-03-24, following a pattern of consistent maintenance with no failures since 2023. However, the vehicle’s history reveals a critical incident in 2023-03-31 when it failed due to dangerous tyre defects—near-side and offside front inner tyres exhibiting bulges indicative of sidewall separation, alongside a near-side rear inner tyre failure. While the subsequent MOTs have returned to passing status, the persistence of tyre-related advisories in 2026 suggests either unresolved underlying issues or a recurring vulnerability in tyre construction or handling. The absence of further tyre failures since 2023 does not mitigate the risk posed by the 2023 defects, which could reoccur or exacerbate with continued use, particularly if the vehicle has been subjected to aggressive driving or poor road conditions. The recorded mileage of 66,617 miles for an eight-year-old GLE reflects a moderate annual usage rate of approximately 8,327 miles per year, which is within the expected range for this vehicle class. Such mileage does not inherently indicate excessive wear, but it does imply regular operation rather than prolonged idling or low-mileage storage. However, the 2023 failure period—spanning roughly 18 months—could have been influenced by either a single high-stress event or cumulative fatigue from repeated exposure to harsh conditions, such as deep potholes, uneven surfaces, or improper tyre maintenance. Buyers should be cautious about any potential residual tyre fatigue, especially if the vehicle has been driven on roads prone to severe damage, as the risk of further sidewall failures remains elevated until the tyre structure is fully reassessed. Given the tyre history, the prospective buyer must prioritise a thorough inspection of all four tyres, focusing on the front inner and rear inner positions where failures were recorded. Look for signs of further bulging, cracking, or separation in the sidewall, particularly around the shoulder and tread transition areas. On a test drive, listen for unusual tyre noise or vibrations that could indicate internal damage, and monitor for uneven wear patterns that might suggest misalignment or poor alignment. If the tyres appear structurally compromised, they should be replaced immediately, as the risk of sudden failure is unacceptable. Beyond tyres, the vehicle’s suspension and steering components may also warrant attention, as repeated tyre failures can sometimes correlate with worn suspension bushes or misaligned wheels. For the rest of the vehicle’s roadworthiness, the buyer should conduct a visual and functional inspection of the remaining components. Given the oil leak advisory from 2026, check under the vehicle for any persistent oil stains or drips, particularly around the engine bay, transmission area, and rear axle. The front brake discs, which were noted as worn but not seriously weakened, should be inspected for signs of glazing, warping, or excessive thickness reduction, as well as any corrosion or binding in the calipers. The brake system’s performance should be tested by applying the brakes firmly and evenly, listening for any grinding, squealing, or pulsation that could indicate worn pads, warped discs, or binding mechanisms. Additionally, the vehicle’s fluid levels—particularly the engine oil, brake fluid, and coolant—should be verified, with a focus on their condition and age, as fluids degrade over time even when not used. For the 2018 model, the coolant should ideally be replaced every five years, regardless of mileage, to prevent corrosion and thermal damage. Finally, the battery should be checked for corrosion on terminals, adequate charge, and overall health, as standing vehicles can accelerate battery deterioration.
