2018 Mercedes-Benz E 4.0L Petrol · E11 TAD

A clear pattern of tyre-related dangerous failures and recurring brake and suspension advisories defines the roadworthiness profile of this 2018 Mercedes-Benz E-Class, with the most recent test on 9 January 2026 passing but flagging a cut nearside rear tyre and a child seat obstructing belt inspection. Across five recorded tests since 2021 there have been three failures, two of them categorised as Dangerous, both due to exposed tyre cords, one on the nearside rear in January 2023 and a simultaneous pair on both front tyres in February 2022. The February 2022 test was further compounded by a brake performance test being declined because the illegal tyres made a roller or decelerometer assessment unsafe to conduct, meaning the actual braking condition at that point was never quantified. Front brake pad wear advisories have appeared at every relevant test from 2022 through 2023, and a nearside front lower suspension arm ball joint with slight play was noted twice in early 2022. The 2021 failure related only to an incorrect registration plate character, which is administrative rather than mechanical. Taken together, the record shows two clusters of tyre cord exposure separated by about eleven months, persistent front brake wear, and a suspension component that has already shown measurable play. The recorded mileage of 43,523 miles over eight years equates to roughly 5,440 miles annually, which is notably low for the vehicle's age and points to either light use, extended standing periods, or a mix of both. A six-month gap exists between the February 2021 retest and the February 2022 test, and a full year elapsed between the January 2023 retest and the February 2024 pass, indicating the car was off the road for stretches. Low annual mileage reduces wear on high-cycle components such as clutches, engines and transmissions, but it can accelerate deterioration of items that suffer from disuse, including tyre sidewalls through cold inflation pressures and prolonged static loading, brake discs through surface corrosion, suspension bushes through dry rot, and brake fluid through moisture absorption during inactivity. The repeated dangerous tyre failures, particularly both fronts failing simultaneously in early 2022, are consistent with a vehicle that may have stood for an extended period before being put back into service, allowing sidewall flex cracking or age-related perishing to develop beyond legal limits without the masking effect of regular tread wear. The mileage record on its own does not establish mechanical condition, but combined with the tyre pattern it warrants closer inspection of age-related deterioration rather than purely wear-related wear. Given the documented history, a prospective buyer should physically inspect all four tyres with particular care, looking for sidewall cracking, perishing, bulges, or exposed ply on the inner as well as outer shoulders, and confirming the DOT manufacture date stamps to ensure none are more than around six years old, as the dual front tyre failure strongly suggests age degradation rather than kerb impact damage. The front brakes should be examined for pad thickness remaining, disc lip depth, and any scoring, with an expectation that pads may now be approaching replacement if the 2023 advisory was not actioned; on a test drive, any grinding, squeal under light braking, or vibration through the pedal would indicate the discs have also worn or warped. The nearside front lower suspension arm ball joint flagged in 2022 warrants a specific check by rocking the wheel at top and bottom while listening for a clonking or rattle, and on the road any knock over uneven surfaces, vague steering response, or a tramlining tendency to one side would suggest the joint or surrounding bushes have deteriorated further. Brake feel should be tested from a standing start with a firm pedal application to confirm there is no excessive travel or sponginess that might indicate seized caliper slide pins or a hydraulic issue masked when the decelerometer test was previously declined. Beyond the flagged components, a thorough inspection should include a check for fluid leaks from the engine, transmission and differential areas, as standing periods can dry seals that then weep on reactivation, and a cold-start observation for any blue smoke indicating valve seal drying. The underbody should be examined for surface corrosion, particularly around suspension mounting points, subframe seams and brake pipe clips, given the vehicle's age and the likelihood of some winter road salt exposure even at low mileage. On the test drive, listen for any clonks from the rear suspension over speed humps, as the nearside rear tyre worn close to the legal limit and on its edge in 2022 hints at a possible rear geometry or shock absorber issue, and confirm the electronic parking brake applies and releases cleanly, since it was specifically excluded from the 2022 test. Finally, verify that the registration plates display the correct HY18 HWV designation as resolved after the 2021 failure, and ensure the tyre size and load rating match manufacturer specifications, as incorrect fitment can itself trigger the kind of rapid wear pattern observed in the record.
