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
MorrisUsed-car reliability
How reliable is a used Morris?
Here's how a used Morris holds up at the MOT, model by model.
What actually goes wrong
What breaks on Morris cars
The most common MOT faults across the Morris range, in plain English. Models with more MOT tests count for more. The percentage is the share of MOT tests on Morris cars that recorded that defect.
6.3%
Brakes uneven from one side to the other
The main (foot) brakes aren't reaching the minimum required stopping force. The car may take longer to stop than it should.
5.4%
Brake binding slightly
The main (foot) brakes aren't reaching the minimum required stopping force. The car may take longer to stop than it should.

Tyre condition
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 slightly damaged, cracking or perishing
Across all Morris models; models with more MOT tests count for more.
The whole range
Every Morris 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. 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.
0 models
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.
