2010 Citroen Grand C4 — MOT failures & pass rate
543 MOT tests on the 2010 Citroen Grand C4 are in this dataset, and 70.9% of them passed. Against all cars of a similar age (24.1% fail rate), the 2010 Grand C4 comes out 5.0pp worse. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
Lighting & signalling dominates the failure mix at 25.8% of all tests — 14.0 points clear of suspension, so it is the first thing to check.
At component level the recurring items are position lamp, headlamp aim and stop lamp — position lamp alone was recorded 95 times.
Mileage is the strongest signal on the record: 27.7% of 60-90k cars fail, rising to 40.0% once past 150k.
Advisories point at the next bill rather than this one: tyres was flagged on 32.2% of tests without failing them.
The trend is worsening — 26.1% of tests failed in 2021 against 32.5% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2010 Grand C4
On a 2010 Grand C4, lighting & signalling is what the MOT record says goes wrong most — it appeared in 25.8% of tests. Check these areas before you commit.
- Lighting & signalling (25.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (11.8% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Brakes (10.1% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
