MOT statistics

Isuzu MOT pass rates

Isuzu cars and vans went through 45,749 MOTs in 2025, and 31.6% failed first time, counting those repaired during the test. That's 3.9 percentage points worse than the national average. The D-Max is the only Isuzu model with its own page here, and the rest are counted in the make's figures.

How does the Isuzu D-Max do at its MOT?

Initial fail rate: failed outright, or passed only after a defect was fixed during the visit. Lower is better.

Model	Tests	Initial fail rate
D-Max	37,239	29.1%

Models without a row here, including any with fewer than 12,000 tests in the year, still count towards the make's total.

How much does an Isuzu MOT cost?

The same as any other make: test centres set their own price, up to the legal maximum of £54.85 for a car or a van up to 3,000kg, or £58.60 for a Class 7 van of 3,000kg to 3,500kg.

How should you use these figures when buying an Isuzu?

A make-level average hides as much as it shows. It lumps younger cars in with older ones and careful owners with careless ones, and older cars fail far more often. The D-Max page breaks the rate down by age, which is the fairer guide.

Then check the actual car. Averages can't see a skipped service or a winter of warning lights, but the car's own record can. Run the plate through our free MOT check for the current position, or the £5.00 report for every test, the mileage trail and the registered spec.

Isuzu MOT: common questions

Is an Isuzu more likely to fail its MOT than average?

Yes. 31.6% of Isuzu MOTs in 2025 failed first time, counting those repaired during the test, against 27.7% across all cars and light vans, which is 3.9 percentage points worse. A make with more older cars on the road fails more often, so compare models age for age.

What does an Isuzu fail its MOT on most often?

Lamps, reflectors and electrical equipment was the category with the most defects recorded at Isuzu MOTs in 2025, ahead of suspension. Both are checked on every car, so a pre-MOT look at them is time well spent.
