The picture
Across 1,494 MOT tests, the Grandland X Business Ed Nav T returns 88.5% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is tyre tread under the limit. A seriously damaged tyre and brake pads worn below 1.5 mm round out the top three. Average tested mileage sits at 23,519, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.

Year-band analysis
First-time MOT pass rate split by registration band. A 1.5-point gap between bands is modest — the year you buy Vauxhall Grandland X Business ED Nav T makes a small but real difference to MOT outcomes.
Best band to buy
91.6%
2021+ registration
the 2021-on band climbs to 91.6% — a 1.5-point improvement. Failures here are mostly wear items: tread depth below requirements of 1.6mm, excessively fluctuating — the structural issues that drag down older examples don't appear in the top-10 for this band. Post-2020 examples are early in their MOT life and generally show the cleanest records.
Band to be cautious about
90.1%
2018–2020 registration
On the 2018–2020 band, the data shows a 90.1% pass rate against a fleet average of 91.6% on the newer band. The main culprits logged at test: tread depth below requirements of 1.6mm, less than 1.5 mm thick, and has a cut in excess of the…. Average mileage on test for this band is 30,657 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2021+ (91.6% first-time pass). Worst band to avoid: 2018-2020 (90.1% pass). That's a 1.5-point spread across 1,992 older tests and 119 newer ones — year of build makes a material difference on this model.

Where it falls short
The new Vauxhall Grandland ticks most of the right boxes for a family SUV, with a roomy cabin and a competitive price. The problem is, it doesn't really shine in any area, and is sub-par in some, particularly when it comes to ride and handling. That's an issue when there are so many strong alternatives.
Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.
If you own a Grandland X Business ED Nav T and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
