Fail rate is first attempts at class 4 tests. Median age is the age of a typical 500e 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 500e in 2025, counted by how many tests each one appeared on.

  1. 1Pins and bushes: pin or bush excessively worn321 tests
  2. 2Wipers: does not clear the windscreen effectively151 tests
  3. 3Condition: has a cut in excess of the requirements deep enough to reach the ply or cords110 tests
  4. 4Pins and bushes: pin or bush likely to become detached59 tests
  5. 5Tread depth: tread depth below requirements of 1.6mm48 tests
  6. 6Condition: has ply or cords exposed46 tests
  7. 7Condition: has a bulge, caused by separation or partial failure of its structure43 tests
  8. 8Washers: not working22 tests

What wears out first

Advisories are the tester flagging wear that is still legal. A typical 500e collects 1.67 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.

  1. 1Tread depth: tread depth below requirements of 1.6mm732 tests
  2. 2Condition: has a tear, caused by separation or partial failure of its structure274 tests
