Where the 500X fails its MOT
Where Fiat 500X 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 track rod end ball joint dust cover excessively damaged or deteriorated so that it no longer prevents the ingress of dirt (14.1%), position lamp not working (13.4%) and tread depth below requirements of 1.6mm (6.3%). See every common 500X MOT failure.
These are DVSA failure records across every Fiat 500X that failed, not a claim that every 500X has these problems.
What should you check when buying a used 500X?
The areas above, most common first, and what an MOT tester looks at in each.
1
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. 23.1% of 500X failure items.
2
Steering
Feel for play, knocking or stiffness in the steering, and check there is no steering warning light. 21% of 500X 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. 16.6% of 500X failure items.
4
Suspension
Listen for knocks over bumps, check the car sits level, and look for leaking shock absorbers and split rubber gaiters. 13.8% of 500X failure items.
5
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. 7.8% of 500X failure items.

What the MOT record doesn't tell you
Knowing Fiat 500X failures cluster around lamps, reflectors and electrical equipment and steering 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 Fiat 500X FAQs
Is the Fiat 500X 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 72.8% first-time pass rate for the Fiat 500X across 36,709 tests in 2025, above the 72.3% average for all cars.
Do older Fiat 500X cars fail their MOT more often?
Fiat 500X cars aged 3 to 5 years passed 86.9% of MOT tests in 2025; for examples aged 6 to 10 years that fell to 69.3%. 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 Fiat 500X?
On the car itself, start with the areas it most often fails on: lamps, reflectors and electrical equipment, steering 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 a Fiat 500X'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.
