Hyundai Ioniq years to avoid? MOT pass rate by year

48,429 initial MOT tests in 2025 on cars first used 2017–2022 · DVSA data · For guidance only · How we count

Hyundai Ioniq years with MOT pass rates below the average for vehicles first used in the same year: 2022. Above it: 2017–2021.

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.

86.2%passed first time

First-time pass rate, all years together: initial tests passed with no repairs. 95% range 85.9% to 86.5%.

In 2025, 86.2% of the 48,429 initial MOT tests on Hyundai Ioniq cars were passed with no repairs. The same-age average, for all vehicles first used in the same years, was 84.2%. That is 1.9 points above the same-age average.

Hyundai Ioniq 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.

When a car's mileage doesn't add up

Does mileage matter?

Hyundai Ioniq first-time pass rates by the mileage at the initial test, all years together, against all vehicles of the same age and mileage.

88.5% of Hyundai Ioniq tests under 30,000 miles passed first time, against 81.3% at 120,000 miles or more. For all vehicles of the same age and mileage, the figures are 90.2% and 74.7%.

120,000 or more6,61081.3%±1.0+6.7 ptsall: 74.7%

Against all vehicles of the same age and mileage, Ioniq tests were below average under 30,000 miles and above average at 30,000 miles or more.

Mileage is only one factor. How a car has been driven and looked after matters too. These figures show an association across all Hyundai Ioniq tests in 2025, not what mileage does to a particular car.

Mileage is the odometer reading at the initial test. Each band is compared with all vehicles first used in the same year with a reading in the same band, weighted by this model's own tests in each year. Bands need at least 1,000 tests. 8 tests (under 0.1%) had no usable odometer reading and are left out. How we count

Common Ioniq problems at the MOT

Share of the 6,700 failed tests with a fault in each area, all years together. A test can count in more than one area, so these add up to more than 100%.

MOT records show roadworthiness faults, not engine or gearbox problems. Each year page compares that year's failure areas with all vehicles first used in the same year.

What to check when viewing a Ioniq

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

  1. Tyres

    In 34.3% of failed Ioniq tests

    • Check the tread on every tyre. The legal minimum for cars is 1.6 mm across the central three-quarters of the tread.
    • Look for cuts, bulges, and wear on only the inner or outer edge, which can point to an alignment problem.
    • Check that the spare wheel or the tyre repair kit is there.

  2. Lights and electrics

    In 32.7% of failed Ioniq tests

    • Ask the seller to help you check every light: dipped and main beam, brake lights, indicators, fog lights and the number plate lamp.
    • Look for cracked, misted or yellowed headlight lenses.
    • Warning lights on the dashboard should come on with the ignition and go out once the engine starts.

  3. Brakes

    In 20.3% of failed Ioniq tests

    • On a clear road, brake firmly. The car should stop in a straight line without juddering or pulling to one side.
    • Check the handbrake holds the car on a slope.
    • Look through the wheels at the brake discs for deep grooves or a raised lip at the edge.

  4. Windscreen, wipers, mirrors

    In 18.9% of failed Ioniq 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.

Tyres

Of Hyundai Ioniq cars that passed their 2024 MOT with a tyre advisory and came back for their next MOT 10–14 months later, 7.1% failed on tyres, against 4.5% of similar cars with nothing noted. Based on 3,957 and 16,875 cars.

Cars not tested again in that window are not included: 21.5% of those with a tyre advisory and 24.8% of the others.

Brakes

Of Hyundai Ioniq cars that passed their 2024 MOT with a brake advisory and came back for their next MOT 10–14 months later, 8.1% failed on brakes, against 3.5% of similar cars with nothing noted. Based on 1,605 and 19,021 cars.

Cars not tested again in that window are not included: 19.4% of those with a brake advisory and 24.5% of the others.

Similar cars are the same model, first-use year and mileage band. Areas are the DVSA's top-level groups, so the later fail may not be the fault that was advised. These figures describe what happened to these cars. They don't show what a repair would have changed.

Hyundai Ioniq questions

Which Hyundai Ioniq years have lower MOT pass rates?

Compared with all vehicles first used in the same year, these model years have below-average MOT pass rates: 2022. Above average: 2017–2021. A pass rate is one signal: it also reflects mileage and upkeep, and doesn't record engine or gearbox faults.

What are the most common Hyundai Ioniq problems at the MOT?

The most common failure areas are tyres (in 34.3% of failed tests), lights and electrics (in 32.7% of failed tests) and brakes (in 20.3% of failed tests). A failed test can count in more than one area.

What mileage is normal for a 3-year-old Hyundai Ioniq?

At their 2025 MOT tests, Hyundai Ioniq cars first used in 2022, about 3 years old, had a median of 26,300 miles. Half had more and half had less.

How do I check a specific Ioniq's MOT history?

Enter its registration in our free check. It lists that car's own MOT results, the faults and advisories recorded and the mileage at each test, and flags repeated advisories and mileage that goes down.

What MOT data can't tell you about any Hyundai Ioniq

Outstanding finance, write-offs, theft and plate changes aren't in MOT records. For a particular car, you need a history check.
