2020 Vauxhall Grandland — MOT failures & pass rate
Across 61,399 MOT tests, the 2020 Vauxhall Grandland recorded a 90.9% pass rate. That is effectively the same as mid-size SUVs of a similar age (8.7% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in tyres, brakes and lighting & signalling.
What the MOT record shows
No single area dominates — tyres (4.8%) and brakes (2.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, brake pads and headlamp aim — tread depth alone was recorded 2,007 times.
Condition tracks the odometer closely. Failures run at 6.8% in the 0-30k band and 15.8% in the 120-150k band, a 9.0-point spread — more than double.
The petrol cars hold up better: 8.6% fail against 12.1% for hybrid, a 3.4-point gap across 50,475 tests.
Tyres is the most common advisory, noted on 23.4% of tests — work that passed today but is likely due soon.
The trend is worsening — 7.0% of tests failed in 2022 against 10.6% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2020 Grandland
The failure pattern for this year is specific enough to inspect against: tyres accounted for 4.8% of tests. Start there.
- Tyres (4.8% 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.
- Brakes (2.4% 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 (1.9% 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.
