Expert verdict
Brakes: 1.8× the national share
Brakes make up 36.8% of everything recorded on the 2021 Citroen C4 Grand Stourer, against 20.9% nationally — 15.9 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 88.0% — 3.2 points below. Age is a fair excuse; this is not age.
- When it fails, it costs. Only 10% 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 C4 Grand Stourer
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.
A test can record several items, so these percentages do not add up to 100%. The exact strings, with prices, are in the full DVSA record at the bottom of this page.
Before your test
Three checks worth doing on a 2021 C4 Grand Stourer
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 brakes 3.8% of tests
“brake pads less than 1.5 mm thick”
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 tyre tread 1.7% 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 lights 1.3% of tests
“headlamp aim too low”
Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.
Shares are the proportion of tests on this vehicle that recorded the item, so they overlap: one test can record several.
