Where the Q50 fails its MOT
Where Infiniti Q50 cars that failed their 2025 MOT were marked down, as a share of all recorded failure items.
The specific items testers recorded most often were tread depth below requirements of 1.6mm (9%), brake pads less than 1.5 mm thick (8.5%) and linkage ball joints ball joint excessively worn (7.4%). See every common Q50 MOT failure.
These are DVSA failure records across every Infiniti Q50 that failed, not a claim that every Q50 has these problems.
What should you check when buying a used Q50?
The areas above, most common first, and what an MOT tester looks at in each.
1
Brakes
Make sure the pedal feels firm, the car stops in a straight line, the handbrake holds on a slope and no brake warning light is showing. 23.2% of Q50 failure items.
2
Suspension
Listen for knocks over bumps, check the car sits level, and look for leaking shock absorbers and split rubber gaiters. 22.9% of Q50 failure items.
3
Tyres
Check tread depth across the full width of every tyre (the legal minimum is 1.6mm), and look for cuts, bulges and uneven wear. 21.1% of Q50 failure items.
4
Lamps, reflectors and electrical equipment
Walk round with every light on: headlights, brake lights, indicators, fog lights and the number plate lamp. Check no warning lights stay on after starting. 16.3% of Q50 failure items.
5
Visibility
Check the windscreen for chips or cracks in the driver's view, and that the wipers and washers clear it properly. 5.6% of Q50 failure items.

What the MOT record doesn't tell you
Knowing Infiniti Q50 failures cluster around brakes and suspension tells you what to inspect. It tells you nothing about whether the car is safe to buy. An MOT does not show money still owed on the car, a write-off, a theft record or a clocked odometer.

Used Infiniti Q50 FAQs
Is the Infiniti Q50 reliable?
MOT data does not measure reliability. It records whether a car met the roadworthiness standard on the day of its test. What it does show is a 75.9% first-time pass rate for the Infiniti Q50 across 2,421 tests in 2025, above the 72.3% average for all cars.
Do older Infiniti Q50 cars fail their MOT more often?
Infiniti Q50 cars aged 6 to 10 years passed 76.4% of MOT tests in 2025; for examples aged 11 years and over that fell to 69.2%. On an older example, the car's own MOT history tells you more than the model average.
What should I check before buying a used Infiniti Q50?
On the car itself, start with the areas it most often fails on: brakes, suspension and tyres. Then check the individual car's history: outstanding finance, insurance write-off records, stolen markers, mileage and previous keepers. None of these appear in the MOT record or on the V5C.
How do I check an Infiniti Q50's history?
Enter the registration of the specific car. A Carpeep car history check reports outstanding finance, write-off category, stolen markers, mileage history, previous keepers, MOT and tax status, import and export markers and scrapped status in one £15 report.
