The most common MOT faults across the Jeep range, in plain English. Models with more MOT tests count for more. The percentage is the share of MOT tests on Jeep cars that recorded that defect.
A tyre is worn, cut, damaged or otherwise not fit for the road. Tyres are the only thing connecting the car to the road, so this is always worth taking seriously.
MOT wording: Tyre worn close to the legal limit or worn on the edge
A suspension arm, wishbone, strut, sub-frame, or anti-roll bar is worn, cracked, bent, or has excessive play. These structural parts hold the wheels in position and control body lean in corners.
MOT wording: Suspension part corroded, but not seriously weakened
A shock absorber (damper) is worn, leaking, or insecure. Worn dampers cause bouncy handling and longer stopping distances because the tyres lose contact with the road.
MOT wording: Shock absorber has a light misting of oil
A suspension ball joint, pin, or rubber bush is worn or has excessive play. These are the pivot points and flexible mountings that let the suspension move — wear causes knocking sounds and vague steering.
MOT wording: Suspension arm pin or bush worn, but not moving too much
Across all Jeep models; models with more MOT tests count for more.
The whole range
For each model, one number: the share of its MOT tests at 7 years old that ended in a fail. Retests count as tests. Lower is better. The UK average (about 1 in 6 MOTs, 16.6%) is shown for reference. Only models with enough MOT data at 7 years old are ranked. The rest sit just below, unranked.

Fail rates are the share of MOT tests on 7-year-old cars ending in a fail, retests included (DVSA MOT results, 2025). UK average across all makes at the same age: 16.6%. How we count fail rates
Shown unranked. These models don’t have enough MOT data at 7 years old yet. They’re either too new (few cars old enough) or too old (few still on the road). Each is shown at the age with the most tests, so the percentages aren’t directly comparable to the list above.
Averages tell you the odds across the range. Enter a number plate to see that car’s own MOT history, its risk rating, and what’s likely to need attention.
