2020 Renault Trafic Sh30 B-Ness+ — MOT failures & pass rate
419 MOT tests on the 2020 Renault Trafic Sh30 B-Ness+ are in this dataset, and 84.0% of them passed. Against all cars of a similar age (9.4% fail rate), the 2020 Trafic Sh30 B-Ness+ comes out 6.6pp worse. Failures cluster in suspension, brakes and lighting & signalling.
What the MOT record shows
No single area dominates — suspension (7.6%) and brakes (6.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are brake pads, headlamp aim and malfunction indicator lamp — brake pads alone was recorded 27 times.
Condition tracks the odometer closely. Failures run at 15.4% in the 0-30k band and 19.7% in the 60-90k band, a 4.3-point spread.
Brakes is the most common advisory, noted on 13.1% of tests — work that passed today but is likely due soon.
The trend is worsening — 13.3% of tests failed in 2023 against 19.1% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2020 Trafic Sh30 B-Ness+
The failure pattern for this year is specific enough to inspect against: suspension accounted for 7.6% of tests. Start there.
- Suspension (7.6% 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.
- Brakes (6.4% 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.
- Lighting & signalling (4.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
