2023 Vauxhall Grandland — MOT failures & pass rate
The 2023 Vauxhall Grandland passed 92.8% of its 498 recorded MOT tests. Mid-size SUVs of a similar age fail 5.6% of the time, so this is 1.6pp worse than the group it competes with. Failures cluster in tyres, lighting & signalling and seat belts & restraints.
What the MOT record shows
No single area dominates — tyres (4.2%) and lighting & signalling (3.0%) 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 stop lamp — headlamp aim alone was recorded 11 times.
Advisories point at the next bill rather than this one: tyres was flagged on 22.9% of tests without failing them.

What to check before buying a 2023 Grandland
On a 2023 Grandland, tyres is what the MOT record says goes wrong most — it appeared in 4.2% of tests. Check these areas before you commit.
- Tyres (4.2% 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 (3.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Seat belts & restraints (1.0% of tests): Belt damage or faulty pretensioners — usually straightforward but safety-critical. Typical repair: £50–£300.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
