How unusual this is for the make

Across all MOT failures, Peugeots fail 1.19× as often as comparable cars. On this item the gap is 2.61× wider than that overall level, so it is a genuine Peugeot pattern rather than a reflection of how often the make fails in general. It is a major defect in the body, chassis and structure part of the test. Nationally it appears on 1.36% of MOT tests.

Peugeot models and “Joints: constant velocity boot split or insecure, no longer prevents the ingress of dirt”

The Peugeot 2008 is most affected (10.31× comparable cars); the Peugeot 107 least (0.30×). Not every model follows the make: the pattern is concentrated in some models. Model rows compare with cars of the same age and fuel.

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 Peugeot 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.
