Tyre worn close to the legal limit or worn on the edge
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.

Where to start
The lowest and highest fail rates in the Lexus range
The Lexus models whose MOT tests at 7 years old most and least often ended in a fail. All of them fail less often than the average car this age (about 1 in 6 MOTs, 16.6%).
What actually goes wrong
What breaks on Lexus cars
The most common MOT faults across the Lexus range, in plain English. Models with more MOT tests count for more. The percentage is the share of MOT tests on Lexus cars that recorded that defect.

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 arm pin or bush worn, but not moving too much

Tyre slightly damaged, cracking or perishing
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.

Brake linings and pads
Brake pads or linings are worn, contaminated, or missing. These are the friction materials that press against the disc or drum to slow the car. When too thin, stopping distances increase.
MOT wording: Brake pads wearing thin
Across all Lexus models; models with more MOT tests count for more.
The whole range
Every Lexus 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.

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.
