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.

Hyundai Bayon 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.

Year	Chart	Testsmedian miles	Passed first time	Against all vehicles that year
2022age 3		3,83220,400	82.7%±1.3	−5.8 ptsall: 88.5%
2021age 4		1,30125,800	89.9%±1.8	+2.7 ptsall: 87.2%

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.

What to check when viewing a Bayon

Based on the areas where Hyundai Bayon MOT tests fail most often. These are general checks anyone can do, not a mechanical inspection.

Windscreen, wipers, mirrors
In 59.0% of failed Bayon tests
- Look for chips and cracks in the windscreen, especially in front of the driver.
- Run the wipers and washers. The blades should clear the screen without smearing.
- Check both door mirrors and the rear-view mirror are intact and adjust.

Then read the car's own MOT history. Advisories in the same area at several tests are worth asking about.
