Verdict
Isuzus pass their MOT first time on 68.7% of tests, against 71.6% for a typical vehicle of the same age and mileage. That beats 33% of cars on UK roads and ranks Isuzu 31st of 40 makes.
Three quarters of the tests are of the D-Max, which beats only 25% of cars, so it sets the make's result. The older Rodeo is close to average, beating 44%. Both are pick-ups, many used for work, and like vans they are pulled down partly by commercial use. Only the Trooper, the oldest and least common, is above average, beating 65%.
Isuzus fail on body and structure about twice as often as a typical vehicle (on about 1 in 16 tests), and on brakes, suspension and seat belts about 1.4 times as often. Lights and electrics fail on about 15% of tests, also about 1.4 times the typical rate. Tyres are the exception: they fail about half as often as on a typical car.

Isuzu models
Models with 20,000+ MOT tests, most common first. Grades compare each car with cars of the same age and mileage (A = best 20% of cars on UK roads, E = worst 20%), so an older or higher-mileage car can grade above one with a higher pass rate. Light vans are included and tend to grade lower, partly from hard commercial use.

| Rodeo 2004–2012 | 55.3% | Beats 44% | C |

FAQ
What is Isuzu's MOT pass rate?
68.7% of Isuzu MOT tests were passed first time, from 342,114 tests. A typical vehicle of the same age and mileage passes 71.6%, so Isuzu is below average.

What are the most common MOT failures on Isuzus?
Lights and electrics (on about 15% of tests), suspension (about 12%) and brakes (about 10%), each more often than on a typical vehicle. Body and structure fails are about twice as common as typical.
