Is the Bentayga getting worse?

The fail rate fell 0.2 points to 4% from 2022 to 2025 while the median one tested aged 2 years. Ageing alone would predict about 4.2 points, so it is holding up better than the fleet average for its age.

Fail rate is first attempts at class 4 tests. Median age is the age of a typical Bentayga at its test that year, and it is the number to watch: across the whole fleet each extra year of age adds roughly 1.9 points to the fail rate, so a model whose age and fail rate rise together is simply getting older.

The exact defects that fail it

Every failure item DVSA recorded against a Bentayga in 2025, counted by how many tests each one appeared on.

  1. 1Condition: has a cut in excess of the requirements deep enough to reach the ply or cords31 tests
  2. 2Pins and bushes: pin or bush excessively worn13 tests
  3. 3Condition: has a bulge, caused by separation or partial failure of its structure11 tests
  4. 4Registration plates: does not conform to the specified requirements9 tests
  5. 5Tread depth: tread depth below requirements of 1.6mm8 tests
  6. 6Condition: has ply or cords exposed7 tests
  7. 7Malfunction indicator lamp: inoperative or indicates a malfunction7 tests
  8. 8Catalyst emissions: Lambda reading after 2nd fast idle outside specified limits5 tests

What wears out first

Advisories are the tester flagging wear that is still legal. A typical Bentayga collects 1.9 of them per test, and these are the ones that come up most. Treat it as the running-repairs list for the next year or two.

What does a Bentley Bentayga usually fail on?

The single most common failure is "Condition: has a cut in excess of the requirements deep enough to reach the ply or cords", recorded on 31 failed tests, followed by "Pins and bushes: pin or bush excessively worn" and "Condition: has a bulge, caused by separation or partial failure of its structure". By section, tyres appears in 56.6% of failures, identification of the vehicle appears in 12.4% of failures, noise, emissions and leaks appears in 11.5% of failures.

Does age change the odds?

Sharply. At 3 to 5 years old the fail rate was 3.5%; at 6-9 years it was 4.2%. The median Bentley Bentayga tested in 2025 was 6 years old with 34,448 miles.

Is the Bentley Bentayga getting less reliable?

The fail rate fell 0.2 points to 4% from 2022 to 2025 while the median one tested aged 2 years. Ageing alone would predict about 4.2 points, so it is holding up better than the fleet average for its age.
