2019 Infiniti Q50 3.5L Hybrid electric · N9 GCF

The vehicle’s most recent MOT tests reveal a mixed but concerning pattern, with the April 2026 failure—just three months ago—highlighting persistent, avoidable issues. The double entry on the same date (one pass, one fail) suggests administrative confusion rather than genuine roadworthiness, though the fail itself underscores critical oversights: a non-functional tyre pressure monitoring system and an illegible rear number plate. While the June 2024 test showed minor offside front anti-roll bar play, the June 2023 failure was far more severe, with four tyres cut to dangerous depths and widespread disc corrosion. This indicates a worsening trend in basic maintenance, particularly tyre care and rust mitigation, rather than any sudden mechanical failure. The April 2026 pass—without defects—implies the tester overlooked the same tyre pressure system issue, reinforcing the need for independent verification. The recorded mileage of 57,728 miles at the latest test aligns with typical usage for a seven-year-old vehicle, averaging around 8,200 miles annually. There are no obvious gaps in service intervals, though the sparse MOT history (only four tests over seven years) makes it difficult to assess long-term wear patterns. The 2023 failure at 36,591 miles and the 2024 pass at 44,077 miles suggest roughly 7,500 miles between tests, which is acceptable but leaves little margin for unforeseen failures. The lack of pre-MOT servicing records means any hidden wear—such as suspension deterioration or drivetrain fluid degradation—cannot be confirmed from this data alone. A buyer should prioritise an immediate inspection of the tyre pressure monitoring system, which failed in April 2026, as its non-functionality poses a direct safety risk. The recurring tyre cuts in 2023—particularly the near- and offside rear tyres—demand close examination for further damage or uneven wear, while the surface rust on braked discs suggests potential brake system corrosion, which could compromise stopping performance. The 2024 advisory on the offside front anti-roll bar ball joint warrants a check for increased play or binding, as this can affect handling and long-term suspension integrity. Given the vehicle’s age and the history of avoidable failures, a thorough brake fluid flush, suspension bush inspection, and underbody corrosion assessment are essential to rule out latent structural risks.
