2018 Toyota Voxy — MOT failures & pass rate
Across 671 MOT tests, the 2018 Toyota Voxy recorded a 95.7% pass rate. Against all cars of a similar age (12.8% fail rate), the 2018 Voxy comes out 8.5pp better. Failures cluster in lighting & signalling, visibility and tyres.
What the MOT record shows
No single area dominates — lighting & signalling (4.3%) and visibility (1.3%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are registration plate lamp(s), rear fog lamp and tread depth — registration plate lamp(s) alone was recorded 15 times.
Mileage matters less than usual here: the 2018 Voxy fails 5.4% of the time in the 0-30k band and 4.9% at 120-150k, a spread of only 0.5 points.
Advisories point at the next bill rather than this one: tyres was flagged on 8.9% of tests without failing them.
The trend is improving — the fail rate fell from 8.8% in 2021 to 4.7% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2018 Voxy
On a 2018 Voxy, lighting & signalling is what the MOT record says goes wrong most — it appeared in 4.3% of tests. Check these areas before you commit.
- Lighting & signalling (4.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (1.3% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
- Tyres (1.3% 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.
