2018 Infiniti Q30 1.5L Diesel · RO67 XSM

The 2018 INFINITI Q30 presents a stable but incomplete maintenance picture based on the available DVSA MOT records. The most recent test, conducted on 31 December 2021 at 35,384 miles, passed but flagged three separate tyre defects: both front tyres worn close to the legal limit and on their edges, plus a nail in the offside rear tyre. These are consumable items rather than structural or mechanical failures, yet the pattern suggests basic upkeep was not consistently prioritised. The vehicle has no recorded MOT since late 2021, meaning it has been without a valid test certificate for over four and a half years as of June 2026. This gap raises questions about whether the car has been in regular use, stored, or simply left untested. The mileage profile is notably low for an eight-year-old vehicle. At 35,384 miles recorded across roughly eight years, the annual average sits around 4,423 miles, well below the typical UK figure of 7,000 to 8,000 miles per year. The jump from 31,537 miles in January 2021 to 35,384 miles by December 2021 accounts for 3,847 miles in under twelve months, which is moderate but not excessive. After that December 2021 reading, no further mileage data exists. The absence of any subsequent MOT entries makes it impossible to confirm whether the odometer has moved significantly or whether the vehicle has been sitting idle for extended periods. Prolonged standing can cause its own issues, including flat-spotted tyres, seized brake calipers, and degraded rubber components. A buyer should approach this car with caution and arrange a thorough in-person inspection before committing. The recurring tyre wear noted in the December 2021 test, particularly the edge wear on both front tyres, points to possible misalignment or worn suspension bushes and tracking geometry. These components should be checked for play and deterioration. The nail in the offside rear tyre at the same test raises the question of whether it was properly repaired or simply left unresolved. Given the four-and-a-half-year gap in testing, the braking system deserves close scrutiny. Binding calipers, corroded brake discs, and deteriorated brake hoses are common on vehicles that have sat unused. Suspension coil springs and dampers should also be inspected for corrosion and leaks, as the Q30's low-volume production means replacement parts can be costly and lead times lengthy. The exhaust system and underbody structural integrity warrant attention as well. Without recent emissions testing data, there is no way to confirm the catalytic converter and lambda sensors remain functioning within legal parameters. Surface corrosion on subframes and suspension mounting points is a known concern on vehicles of this age, particularly those that may have been stored in damp conditions. A pre-purchase inspection by an independent mechanic familiar with the INFINITI Q30 platform is strongly advised before any commitment.
