2018 Ford C-MAX 1.5L Diesel · DN68 GXT

A pattern of rear suspension wear has begun to assert itself on this C-Max, with both nearside and offside rear suspension arm pins or bushes flagged as worn at the most recent test on 29 September 2025, although the defects were not severe enough to result in failure. This is a notable development because the four prior tests between 2021 and 2024 were otherwise free of structural or suspension advisories, suggesting the rear axle components are now reaching a stage where replacement is increasingly likely. Earlier braking wear advisories in 2022 and 2023, covering both front and rear pads, form a consistent pattern of routine consumable use rather than anything abnormal, and the 2023 failure on an illuminated engine management warning light remains an isolated emissions-related event. The current recorded state is therefore one of a pass supported by a cautionary suspension note, with the trend pointing towards rising rear axle intervention rather than a clean bill of health. The recorded mileage of 48,463 miles over roughly eight years equates to an annual accumulation of around 6,058 miles, which sits comfortably within the expected range for a family vehicle of this type and indicates steady, regular use rather than extended periods off the road. There are no significant gaps in the testing history, with annual entries present from 2021 through 2025, and the mileage progression between tests is broadly consistent rather than showing sudden spikes that might suggest inconsistent record-keeping or rapid accumulation. This pattern of regular, moderate use tends to be less corrosive to drivetrain and suspension components than a vehicle that has been left standing for long periods, where seized calipers, perished rubber, and degraded fluids can become concerns, but the usage is sufficient that consumables such as brake pads, discs, and tyres will have seen realistic service. For a prospective buyer, the rear suspension advisories should form the primary focus of any inspection. The reference to worn pins or bushes on both sides suggests the rear trailing arm or control arm bushes are deteriorating, which on a C-Max typically translates into a degree of vagueness in the rear end, audible knocking or clonking over broken surfaces, and uneven tyre wear across the rear axle. It is worth jacking the vehicle and physically checking the rear bushes for cracking, splitting, or visible movement relative to the mounting bolts, and any knocking reported during a test drive over speed humps or potholes should be treated as a probable indicator that the components flagged at the 2025 test have deteriorated further. The front suspension does not appear in the record, but given the rear wear pattern a thorough check of the front anti-roll bar drop links, wishbone bushes, and top mounts would be prudent. The 2023 engine management light failure warrants verification that the underlying fault has been resolved rather than simply cleared from the system. On the 1.0 EcoBoost or 1.5 TDCi engines fitted to this generation of C-Max, common causes include ignition coil or spark plug failure, lambda sensor degradation, or evaporative emission system leaks, and any recurrence of the warning light, rough idle, hesitation under load, or elevated idle speed during a test drive would suggest the original repair has not held. The brake history, while routine, also merits physical confirmation: with front pads noted as thin in 2022 and rear pads noted as thin in 2023, both sets have likely been replaced since, and a check of current pad material thickness along with disc condition, particularly lipping on the front discs, is worthwhile. Finally, although no corrosion advisories appear in the record, a visual inspection of the rear subframe mounting points, brake pipes along the underbody, and wheel arch lips remains advisable, as C-Max examples of this vintage can develop surface corrosion in these areas that may not yet have reached the threshold for advisory recording.
