2017 Porsche Cayenne 4.1L Diesel · CSZ 6

A pattern of immediate tyre wear is the primary mechanical concern identified in the most recent inspection on 20 April 2026. While the vehicle has maintained a consistent pass record since a registration plate non-conformity failure in June 2023, the latest test introduced advisories for all four tyres being worn close to the legal limit or worn on the edges. This suggests a potential issue with wheel alignment, camber settings, or suspension geometry that warrants investigation, as the previous two years of testing in 2024 and 2025 showed no recorded defects. The vehicle has covered 99,781 miles over its nine-year lifespan, averaging approximately 11,087 miles per year. This usage profile is consistent with typical UK driving patterns for a premium SUV of this age. Mechanically, this level of accumulation means that components subject to regular friction and load, such as suspension bushes, brake pads, and drivetrain mounts, will have undergone significant cycles of stress. The steady mileage accumulation suggests the vehicle has been in regular use rather than sitting stationary for extended periods, which typically helps prevent the degradation of rubber seals and fluids, though it increases the expected wear on consumable items. Given the specific advisories regarding edge wear on all four tyres, a prospective buyer should pay close attention to the vehicle's handling during a test drive. Listen for any rhythmic thumping or humming noises from the wheel arches, which can indicate uneven tread wear or tyre deformation. More importantly, monitor the steering for any pulling to one side under braking or during straight-line driving, as this can be a symptom of the alignment issues flagged in the April 2026 test. Any noticeable wandering or a lack of precision in the steering response could indicate that the suspension components responsible for maintaining wheel geometry, such as control arms or tie rod ends, require attention. Beyond the tyres, the high mileage necessitates a thorough check of the braking system and suspension integrity. While no specific brake or suspension defects were recorded in the recent history, the transition from a clean record to multiple tyre advisories suggests that the mechanical components governing tyre contact are under scrutiny. During the test drive, feel for any vibrations through the steering wheel or brake pedal, and listen for knocks or clunks when navigating uneven surfaces or speed bumps, which would indicate wear in the suspension linkages or bushes.
