2021 Renault Trafic Ll30 — MOT failures & pass rate
Across 638 MOT tests, the 2021 Renault Trafic Ll30 recorded an 87.6% pass rate. All cars of a similar age fail 8.6% of the time, so this is 3.8pp worse than the group it competes with. Failures cluster in tyres, brakes and suspension.
What the MOT record shows
No single area dominates — tyres (4.9%) and brakes (4.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are brake pads, tread depth and track rod end — brake pads alone was recorded 27 times.
A 90-120k example is materially riskier than a 0-30k one: 19.1% versus 7.6%.
Advisories point at the next bill rather than this one: brakes was flagged on 21.0% of tests without failing them.

What to check before buying a 2021 Trafic Ll30
On a 2021 Trafic Ll30, tyres is what the MOT record says goes wrong most — it appeared in 4.9% of tests. Check these areas before you commit.
- Tyres (4.9% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Brakes (4.7% 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.
- Suspension (3.5% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
