Mercedes-Benz EQB reliability: MOT pass rate and common faults

2,633 initial MOT tests in 2025 on cars first used in 2022 · DVSA data · For guidance only · How we count

Mercedes-Benz EQB cars first used in 2022 had an MOT pass rate below 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.

Mercedes-Benz EQB 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		2,63329,000	85.3%±1.5	−3.2 ptsall: 88.5%

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?

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

86.3% of Mercedes-Benz EQB tests under 30,000 miles passed first time, against 84.0% at 30,000 to 59,999 miles. For all vehicles of the same age and mileage, the figures are 91.1% and 84.7%.

Miles at the test	Tests	Passed first time	Against all vehicles, same age and mileage
Under 30,000	1,399	86.3%±2.0	−4.8 ptsall: 91.1%
30,000–59,999	1,128	84.0%±2.3	−0.7 ptsall: 84.7%

Against all vehicles of the same age and mileage, EQB tests were below average under 30,000 miles and about average at 30,000 to 59,999 miles.

Mileage is only one factor. How a car has been driven and looked after matters too. These figures show an association across all Mercedes-Benz EQB 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. Not shown, with fewer than 1,000 tests: 60,000–89,999, 90,000–119,999 and 120,000 or more. 1 test (under 0.1%) had no usable odometer reading and is left out. How we count

Common EQB problems at the MOT

Share of the 388 failed tests with a fault in each area, all years together. A test can count in more than one area, so these can add up to more than 100%.

Tyres72.7%

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

What to check when viewing an EQB

Based on the areas where Mercedes-Benz EQB MOT tests fail most often. These are general checks anyone can do, not a mechanical inspection.

Tyres
In 72.7% of failed EQB 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.

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