2023 Vauxhall Mokka — MOT failures & pass rate
Across 1,507 MOT tests, the 2023 Vauxhall Mokka recorded a 93.8% pass rate. Against small SUVs of a similar age (5.1% fail rate), the 2023 Mokka comes out 1.1pp worse. Failures cluster in tyres, lighting & signalling and visibility.
What the MOT record shows
No single area dominates — tyres (2.9%) and lighting & signalling (1.9%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, tread depth and wipers — headlamp aim alone was recorded 28 times.
Advisories point at the next bill rather than this one: tyres was flagged on 13.2% of tests without failing them.

What to check before buying a 2023 Mokka
On a 2023 Mokka, tyres is what the MOT record says goes wrong most — it appeared in 2.9% of tests. Check these areas before you commit.
- Tyres (2.9% 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.
- Lighting & signalling (1.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (1.4% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
