2021 Renault Trafic Sl28 A — MOT failures & pass rate
Across 333 MOT tests, the 2021 Renault Trafic Sl28 A recorded a 90.4% pass rate. All cars of a similar age fail at 8.6%, so the 2021 Trafic Sl28 A sits squarely on the average. Failures cluster in lighting & signalling, suspension and tyres.
What the MOT record shows
No single area dominates — lighting & signalling (4.5%) and suspension (3.6%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are shock absorbers, tread depth and brake pads — shock absorbers alone was recorded 10 times.
Condition tracks the odometer closely. Failures run at 4.8% in the 0-30k band and 14.7% in the 60-90k band, a 9.9-point spread — more than double.
Advisories point at the next bill rather than this one: brakes was flagged on 17.7% of tests without failing them.

What to check before buying a 2021 Trafic Sl28 A
On a 2021 Trafic Sl28 A, lighting & signalling is what the MOT record says goes wrong most — it appeared in 4.5% of tests. Check these areas before you commit.
- Lighting & signalling (4.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (3.6% 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.
- Tyres (2.4% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
