Toyota bZ4X reliability: MOT pass rate

1,200 initial MOT tests in 2025 on cars first used in 2024 · DVSA data · For guidance only · How we count

Toyota bZ4X cars first used in 2024 had an MOT pass rate above the average for their age.

The MOT pass rate is one signal, not the whole story. An MOT checks safety and emissions on the day of the test. It doesn't record gearbox or engine faults, and a pass rate also reflects mileage and upkeep, so the table shows median mileage too. Whatever the year, the car in front of you matters more than its model's average.

Toyota bZ4X MOT pass rate by year

Year is when the car was first used. Older vehicles fail more often, so each year is compared with all vehicles first used that year.

Tests are initial MOT tests in 2025, not retests. Median miles is the middle odometer reading at the test: half had more, half had less. ± is the 95% margin of error in points (Wilson interval): a difference smaller than that could be chance. Years without a link have fewer than 10,000 tests, so they are listed here but don't have their own page.

Common bZ4X problems at the MOT

No failure area had at least 50 failed tests, so we don't list any.

MOT records show roadworthiness faults, not engine or gearbox problems. An MOT doesn't test an electric car's battery health or range.
