Brumble MOT Reliability Index 2025
Which car brands pass their MOT first time most often? We looked at the first MOT test of 28.8 million cars tested in Great Britain in 2025, and allowed for how old each car was.
In 2025 MOT tests across Great Britain, Porsche had the highest first-time pass rate of any popular car brand, once age is taken into account. Dacia had the lowest.
Popular brands are those with 100,000 or more tests. These are MOT results only. They do not tell you about breakdowns or repair costs.

Check a vehicle's MOTWhat This Index Shows
- It shows how often cars pass their MOT first time, by brand and by model.
- It does not measure breakdowns, repair costs or how reliable a car is mechanically.
- Many MOT failures are for parts that wear out, like bulbs, tyres and wiper blades. How well a car is looked after matters as much as how it was made.
- Older cars fail more often. Some brands sell mostly new cars and some have lots of older ones, so we adjust for age to compare them more fairly.
- The figures cover MOT tests in Great Britain (England, Scotland and Wales).
Car Brands Ranked by First-Time MOT Pass Rate
This list covers car brands with 20,000 or more first MOT tests. The adjusted rate is the pass rate after allowing for the age of each brand's cars. All cars passed 72.6% of the time.
- Pass rate: the share of cars that passed first time.
- Expected: the pass rate we would expect, given how old the brand's cars are.
- Adjusted for age: the pass rate if the brand's cars had the same age mix as all cars.
- Miles vs same age: how far the brand's cars had driven, compared with other cars of the same age. We do not adjust for this.

Specialist and Smaller Brands
These brands had between 2,000 and 19,999 first MOT tests. Many are sports or luxury cars that are driven less and looked after closely, so take care comparing them with everyday brands.

Car Models
Every car model with 2,000 or more first MOT tests. We group the model names in the MOT data into the names people know, so FOCUS ZETEC and FOCUS ST-LINE both count as Focus.
When two different cars share a name, we split them by the year they were first used, for example Puma (up to 2002) and Puma (2019 on).
"Compared with cars the same age" shows how many percentage points a model's pass rate was above or below what we would expect, given how old its cars were. For example, +5.0 points means it passed 5 points more often than cars of the same ages usually do.

Vans and Pickups
Vans and pickups are not in the car tables. Here we compare them with each other. They include larger vans, which take a different MOT (class 7). We adjust for age against all vans and pickups, which passed 65.2% of the time.
The MOT data does not say whether a vehicle is a van or a people carrier. Some small vans share a name with a passenger version, so those rows include both. Some larger vans are made into motorhomes.

Pass Rate by Fuel Type
Hybrid and electric cars have high pass rates, but they are also much younger than petrol and diesel cars, so we adjust for age. After adjusting, electric cars came out a little below petrol cars (70.8% against 72.5%). At their first MOT, electric cars passed 87.3% of the time, against 90.4% for petrol cars.

Pass Rate by Postcode Area
This is the postcode area where the MOT test was done, not where the owner lives. You can search by postcode area, like CF, or by town, like Cardiff. Pass rates can differ between areas because of the roads, the weather and how cars are used, as well as how tests are carried out. The adjusted rate allows for the age of the cars tested in each area.

Brumble MOT Reliability Index Methodology
Which tests we count
- We use the MOT test results that the Driver and Vehicle Standards Agency (DVSA) publishes for Great Britain. This edition covers tests done from 1 January to 31 December 2025.
- For cars, we use class 4 tests. For vans and pickups, we also use class 7 tests, which cover larger vans.
- We count only the first normal MOT test of each vehicle in the year. Retests are left out, so each vehicle counts once.
- Pass rate = passes ÷ (passes + fails + passes after faults were fixed at the test centre). This is the same way DVSA works it out. A car that had a fault fixed during the test counts as a fail.
- For what cars fail on, we count dangerous and major faults, including ones fixed at the test centre. Minor faults and advisories are not counted.
How we adjust for age
We work out the pass rate for all cars at each age. For each brand, we then work out the pass rate we would expect, given how many of its cars are each age. The adjusted rate is the pass rate for all cars, multiplied by the brand's real pass rate, divided by its expected pass rate. This is called indirect standardisation.
A worked example
- Say cars aged 3 pass 90% of the time and cars aged 10 pass 60% of the time. All cars together pass 75% of the time.
- A brand has 300 cars aged 3 and 100 cars aged 10.
- We would expect it to pass (300 × 90% + 100 × 60%) ÷ 400 = 82.5% of the time.
- It really passed 87.5% of the time, which is better than expected.
- Its adjusted rate is 75% × 87.5 ÷ 82.5 = 79.5%.
- We measure age as full years from the date the car was first used to the date of the test. Cars can have their first MOT up to a month before they turn 3, so most first MOTs show as age 2. In 2025, cars aged 2 passed 89.7% and cars aged 3 passed 88.6%. Our "First MOT" group is ages 0 to 2.
- We use each single year of age up to 29. Cars aged 30 or more are grouped together.
- We do not adjust for mileage. We show how far each brand's cars had driven compared with other cars of the same age, so you can see where it might matter.
- The adjustment can be misread. A high adjusted rate does not mean a brand's cars will pass that often. It means they did better than cars of the same age usually do.
- For car models, we do not show an adjusted rate. Some models are mostly old cars that are driven very little, and for these the adjusted rate can go above 100%, which is not a real pass rate. Instead we show how many percentage points each model was above or below its expected rate. The download still has the expected and adjusted rates for every model.
Brands and models
- We join make names that are written in different ways: MERCEDES and MERCEDES BENZ count as Mercedes-Benz, RANGE ROVER counts as Land Rover, and SMART (MCC) counts as Smart. London Taxis International counts as LEVC.
- CHRYSLER-JEEP is split into Chrysler, Jeep, Dodge and Chevrolet by model. DODGE (USA) counts as Dodge and CHEVROLET GMC counts as Chevrolet.
- DS is shown on its own. Older DS3, DS4 and DS5 cars sold as Citroens stay with Citroen, as that is how they are recorded.
- MG is split in two. Cars first used in 2010 or earlier, and older MG models like the TF, are shown as MG Rover era. Cars first used from 2011, when the new MG range began, are shown as MG.
- Main table: brands with 20,000 or more tests. Specialist table: 2,000 to 19,999 tests. Models: 2,000 or more tests. Vans: 2,000 or more tests.
- When you filter by fuel or age, we show a figure when it is based on 2,000 or more tests.
What we leave out of the car tables
We started with 31,707,812 class 4 and 1,044,011 class 7 first MOT tests. The car tables use 28,828,560 of them. We left out:
- Vans: 3,350,672 tests (shown in the van table)
- Pickups: 414,814 tests (shown in the pickup table)
- Motorhomes and campervans: 107,612 tests
- Larger goods vehicles that are not on our van list: 36,878 tests
- Trucks, buses and other commercial makes: 7,697 tests
- Quad bikes, trikes and other vehicles that are not cars: 5,590 tests
Because of this, the pass rate for all cars (72.6%) is a little higher than the 71.9% for all class 4 vehicles on our MOT pages, which include vans and motorhomes.
Methodology version: 1.0.
For Journalists
Ryan Hughes, founder of Brumble, said: "Age makes a big difference to MOT results, so we adjusted for it to give a fairer picture of how each brand performs. Whatever you drive, simple checks like lights, tyres and wipers before your MOT can help you avoid an easy fail."
Notes to Editors
- The Brumble MOT Reliability Index 2025 shows how often car brands and models in Great Britain passed their MOT first time in 2025, once age is taken into account.
- We used the MOT results that the Driver and Vehicle Standards Agency (DVSA) publishes. We counted the first normal MOT test of each vehicle in 2025. For each brand, we worked out the pass rate we would expect for cars of the same ages and compared it with the real pass rate. Vans and pickups have their own tables, and motorhomes are left out.
- The figures cover 28,828,560 first MOT tests of cars, 3,350,672 of vans and 414,814 of pickups.
- These are MOT results only. They do not measure breakdowns, repair costs or how reliable a car is mechanically.

Questions and Answers
Once age is taken into account, Porsche had the highest first-time pass rate of any brand with 100,000 or more tests, at 87.3%. Dacia had the lowest, at 63.3%.
72.6% of cars passed their first MOT test of the year in Great Britain. This is based on 28,828,560 tests.
87.3% of electric cars passed at their first MOT, compared with 90.4% of petrol cars. Electric cars are much younger on average, so their overall pass rate looks high until age is taken into account.
Lights and electrics came up most often: 37.1% of failed tests had at least one dangerous or major fault there. Suspension came next, at 32.3%.
Older cars fail more often, so we compare each brand with the pass rate we would expect for cars of the same ages. The adjusted rate shows how a brand might do if its cars had the same age mix as all cars.
No. These are MOT results only. They do not measure breakdowns, repair costs or how reliable a car is mechanically, and many MOT fails are for parts that wear out, like bulbs, tyres and wiper blades.
