How unusual this is for the make
Across all MOT failures, SsangYongs fail 1.54× as often as comparable cars.

It is a major defect in the brakes part of the test. Nationally it appears on 1.11% of MOT tests.

Limitations
Official data: DVSA's anonymised MOT results (2023–2024), class 4 initial tests, cars at least 2.5 years old. 73 Auto analysis: the comparison rate applies the national rate of this item for each test's own age, mileage band and fuel to the SsangYong tests. An MOT result reflects maintenance, mileage and how a car is used as well as its design, so this is not a measure of which make is most reliable. The wording of the defect is DVSA's.
