bZ4X fuel types
Most Toyota bZ4X cars tested in 2025 were electric. Electric cars need an MOT from three years old like any other car, and their tyres, brakes, suspension and lights are tested the same way.
Where the bZ4X fails its MOT
Where Toyota bZ4X 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 condition has a cut in excess of the requirements deep enough to reach the ply or cords (24.6%), headlamp aim too high (13.9%) and tread depth below requirements of 1.6mm (13.9%). See every common bZ4X MOT failure.
These are DVSA failure records across every Toyota bZ4X that failed, not a claim that every bZ4X has these problems.
What should you check when buying a used bZ4X?
The areas above, most common first, and what an MOT tester looks at in each.
1
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. 53.9% of bZ4X failure items.
2
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. 26.2% of bZ4X failure items.
3
Identification of the vehicle
Match the number plates and VIN to the V5C logbook, and check the plates are legal. 6.2% of bZ4X failure items.
4
Visibility
Check the windscreen for chips or cracks in the driver's view, and that the wipers and washers clear it properly. 6.2% of bZ4X failure items.
5
Suspension
Listen for knocks over bumps, check the car sits level, and look for leaking shock absorbers and split rubber gaiters. 4.6% of bZ4X failure items.

What the MOT record doesn't tell you
Knowing Toyota bZ4X failures cluster around tyres and lamps, reflectors and electrical equipment 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 Toyota bZ4X FAQs
Is the Toyota bZ4X 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 97% first-time pass rate for the Toyota bZ4X across 1,855 tests in 2025, above the 72.3% average for all cars.
What should I check before buying a used Toyota bZ4X?
On the car itself, start with the areas it most often fails on: tyres, lamps, reflectors and electrical equipment and identification of the vehicle. 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 Toyota bZ4X'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.
