Fluid leak
The vehicle is leaking a fluid — oil, coolant, fuel or hydraulic. A slight seep is common on older cars; a continuous drip is both a road hazard and a sign of something failing.
MOT wording: Oil leak, but not excessive
BentleyUsed-car reliability
How reliable is a used Bentley?
At 7 years old, the average Bentley fails its MOT less often than the average UK car.

What actually goes wrong
What breaks on Bentley cars
The most common MOT faults across the Bentley range, in plain English. Models with more MOT tests count for more. The percentage is the share of MOT tests on Bentley cars that recorded that defect.
15.9%
Suspension joint, pin or bush
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 ball joint dust cover badly deteriorated
13.2%
Wheel bearing
A wheel bearing is worn or damaged. Wheel bearings let the wheels spin smoothly — when worn, they make a humming or grinding noise and can cause the wheel to wobble.
MOT wording: Wheel bearing has slight play
11.7%
Shock absorber / damper
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
Across all Bentley models; models with more MOT tests count for more.
The whole range
Every Bentley that ranks, in plain English
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. Every model here fails less often than the UK average (about 1 in 6 MOTs, 16.6%). Only models with enough MOT data at 7 years old are ranked. The rest sit just below, unranked.

4.2%fail rate at 7 years old
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
Not directly comparable with the figures at 7 years old
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.
