Expert verdict
Brakes: 2.3× the national share
Brakes make up 47.8% of everything recorded on the 2021 Renault Zoe I B-Ness, against 20.9% nationally — 26.9 points above. Have the discs and pads measured rather than glanced at, and ask whether the handbrake holds on a slope.
- Falls short of its own age and mileage. Like-for-like, cars this age and mileage expect about 91.2%; this one manages 86.2% — 5.0 points below. Age is a fair excuse; this is not age.
- When it fails, it costs. Only 7% of this model’s typical repairs come in under £30 in parts — the failures here tend to be the kind that need a garage rather than a bulb.

What fails a 2021 Zoe I B-Ness
Everything a tester recorded on this vehicle, grouped into the inspection sections that produced it. The notch on each bar is the national share, so you can see at a glance whether this car is unusual or just ordinary.

Before your test
Three checks worth doing on a 2021 Zoe I B-Ness
These are not generic tips — they are the faults recorded most often on this exact model, rewritten as things you can check yourself. All three take about ten minutes and cost nothing.
-
Check the tyre tread 2.0% of tests
“tread depth below requirements of 1.6mm”
Check all four tyres cold, including the inner shoulder where wear hides — 1.6mm across the central three-quarters is the legal limit, and most testers fail at 1.6mm without argument.
-
Check the brakes 1.5% of tests
“brake discs in such a condition that it is seriously weakened”
Look through the spokes of each wheel at the pad — less than 3mm of friction material, or a lip on the disc edge, is the usual failure. Check the handbrake holds on a slope with a few clicks, not at the top of its travel.
-
Check the brake pipes 1.0% of tests
“flexible brake hoses slightly twisted”
Brake pipes run under the car, usually in front of the rear wheels. Flaking or crusty metal is what fails; a light dusting of surface rust does not. Worth asking a garage to look while it is on a ramp.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
