2015 Infiniti Q50 2.1L Diesel · BD15 KLP

This INFINITI Q50 exhibits a persistent pattern of lighting system defects, having failed two MOT tests primarily due to headlamp and position lamp malfunctions. While the most recent MOT on 2025-11-19 resulted in a pass with no defects recorded, this followed an immediate retest on 2024-11-20 after a failure for an offside dipped beam headlamp not working and a defective front wiper blade. A similar failure occurred on 2022-11-23, where it failed for multiple lighting issues including a nearside dipped beam headlamp, offside front position lamp, and an untestable nearside headlamp aim, which was also rectified and passed on the same day. This recurring theme suggests a potential underlying electrical or component reliability concern within the lighting system, despite the recent clean passes. With 137,144 miles recorded over approximately eleven years, this vehicle has accumulated mileage at an average rate of around 12,468 miles per year, which is notably higher than typical for its age. This indicates consistent and substantial use throughout its life, which naturally leads to increased wear on consumable components such as suspension bushes, shock absorbers, brake discs and pads, and the clutch or automatic transmission components. While higher mileage does not inherently imply poor condition, it necessitates a more thorough inspection of these wear items, as they will have experienced greater operational stress compared to a lower-mileage equivalent. Given the history of lighting failures, a prospective buyer should pay particular attention to the functionality of all exterior lamps during a pre-purchase inspection. Check both dipped and main beam headlamps, front and rear position lamps, and ensure all brake lights illuminate correctly, including the high-level stop lamp. Listen for any unusual buzzing or flickering from the lighting units, which could indicate a loose connection or failing LED cluster, as previously noted with a nearside rear stop lamp advisory in 2021. Furthermore, with the elevated mileage, a comprehensive assessment of the suspension and braking systems is crucial. On a test drive, listen for any knocking or creaking noises over bumps or uneven surfaces, which could indicate worn suspension bushes, ball joints, or shock absorbers. Feel for any excessive play in the steering or a lack of damping control. Check the brake pedal for sponginess or judder, which may point to worn brake discs or calipers. Examine the tyres for even wear across the tread, especially the rear tyres, as previous advisories highlighted low tread depth. A thorough visual inspection underneath the vehicle should also be conducted to check for any signs of fluid leaks, corrosion on structural components, or excessive wear on drivetrain components.
