Vauxhall Grandland common problems
The most common reason a Vauxhall Grandland fails its MOT is a tyre worn below the legal limit, on 19.0% of its 12,211 failed tests in 2025. Against other cars of the same age, 5 faults stand out, the widest gaps being: a worn steering or suspension joint at 3.6% of failures against 0.5% expected; a split joint boot at 5.7% of failures against 1.6% expected; a brake light out at 5.4% of failures against 1.8% expected.

What fails a Vauxhall Grandland MOT
Each bar is the share of failed Vauxhall Grandland tests with that defect. Where we can compare it with cars of the same registration years, the marker shows what an average car of those ages records (12 of the 12 items below).
Most common reasons for failure
A test can fail for more than one defect, so shares add up to more than 100%.
| Defect | Share of failed tests |
|---|---|
| Tyres: tread depth below requirements of 1.6mm Tyres | 19.0% |
| Brake pads: less than 1.5 mm thick Brakes | 12.2% |
| Tyres: cut in excess of the requirements deep enough to reach the ply or cords Tyres | 8.2% |
| Headlamp: not working on dipped beam Lamps, reflectors and electrical equipment | 6.8% |
| Drive shafts: constant velocity boot split or insecure, no longer prevents the ingress of dirt Body, chassis, structure | 5.7% |
| Stop lamp: not working Lamps, reflectors and electrical equipment | 5.4% |
| Wipers: does not clear the windscreen effectively Visibility | 5.0% |
| Washers: provides insufficient washer liquid Visibility | 4.7% |
| Headlamp aim: too low Lamps, reflectors and electrical equipment | 4.3% |
| Tyres: ply or cords exposed Tyres | 4.3% |
| Coil spring: fractured or broken Suspension | 4.2% |
| Linkage ball joint excessively worn Suspension | 3.6% |

Tyre worn below the legal limit
19.0% of failures 10.9% expected 1.7 times as often
A tyre worn past the 1.6mm legal minimum across the middle three quarters of the tread.
A 20p coin in the main grooves: if the outer band of the coin is visible, the tyre is close to the limit.
-
Worn brake pads
12.2% of failures 10.1% expected somewhat more often
Friction material worn under 1.5mm, thinner than the point most manufacturers call the limit.
Look through the wheel spokes at the pad against the disc; wear indicators squeal before they get this far.
-
Cut tyre
8.2% of failures 11.3% expected somewhat less often
A cut in the tyre deep or long enough to reach the structure underneath, usually from a kerb or debris.
Run a hand round the inner and outer walls of each tyre, which is where kerbing shows.
-
Headlamp out
6.8% of failures 3.0% expected 2.3 times as often
A headlamp out on dipped beam, which is the beam the test checks.
Both bulbs age at the same rate, so a pair usually goes within months of each other.
-
Split joint boot
5.7% of failures 1.6% expected 3.6 times as often
A split rubber boot on a joint or driveshaft. The joint may still be sound, but dirt and water get in once the boot is open.
Turn the wheels to full lock and look behind them for greasy splits in the rubber concertina.
-
Brake light out
5.4% of failures 1.8% expected 3 times as often
A brake light not working, from a bulb, a poor earth, or the switch on the pedal.
Reverse up to a wall or window at dusk and press the pedal to see all three lamps light.
Which parts of the car fail
Tyres is the area that most often fails a Vauxhall Grandland, on 33.8% of failed tests. The widest gap against cars of the same registration years is body, chassis, structure, on 8.5% against 3.4% expected.

What testers warn about
43.5% of Vauxhall Grandland tests ended with at least one advisory: a fault the tester found that did not fail the test. On Vauxhall Grandlands, these are the items to ask about on a car you are viewing, because they are what the last tester expected to go next.
Most common advisories
Share of all tests, passes included.
| Advisory | Share of tests |
|---|---|
| Tread depth: worn close to legal limit or worn on edge Tyres | 21.7% |
| Brake discs: worn, pitted or scored, but not seriously weakened Brakes | 10.7% |
| Brake pads: wearing thin Brakes | 9.6% |
| Tyres: slightly damaged or cracking or perishing Tyres | 4.8% |
| Child seat fitted not allowing full inspection of adult belt Non-component advisories | 4.1% |
| Brake discs: worn, but not excessively Brakes | 3.1% |
| Nail in tyre Non-component advisories | 2.6% |
| Linkage ball joint has slight play Suspension | 1.5% |
| Engine oil leak, but not excessive Noise, emissions and leaks | 1.4% |
| Tyres: cut but not deep enough to reach the ply or cords Tyres | 1.2% |
| Exhaust system: mounting defective Body, chassis, structure | 1.1% |
| Service brake performance: binding but not excessively Brakes | 0.9% |

Vauxhall Grandland problems: common questions
What is the most common problem with a Vauxhall Grandland?
Of the faults that fail an MOT, “Tyres: tread depth below requirements of 1.6mm” is the most common: it appears on 19.0% of failed Vauxhall Grandland tests. Across categories, tyres is the area that most often fails one, on 33.8% of failed tests.
How often does a Vauxhall Grandland fail its MOT?
16.3% of Vauxhall Grandland tests in 2025 were not passed first time, from 74,783 tests of cars aged three and over. Allowing for the age and mileage of the cars tested, that gives it a UK Motoring Reliability Score of 45 out of 100, where 50 is as expected.
Does anything fail more often on a Vauxhall Grandland than on other cars?
Yes. “Linkage ball joint excessively worn” appears on 3.6% of its failures against 0.5% for cars of the same age, and “Drive shafts: constant velocity boot split or insecure, no longer prevents the ingress of dirt” appears on 5.7% of its failures against 1.6% for cars of the same age. Where an item is missing from the national figures for a year, we use the smallest share those figures show, so the comparison never overstates the difference.
Are these the same as breakdowns or known faults?
No. These are the items a tester recorded at the MOT, which covers condition and safety: lamps, brakes, tyres, suspension, corrosion and emissions. A gearbox that is unpleasant, an infotainment screen that has died, or a car that will not start on a cold morning are not part of the test, so they are not in these figures.
Where do the figures come from?
Every normal MOT test of a Vauxhall Grandland aged three and over in Great Britain in 2025, from DVSA's anonymised MOT results. Retests are excluded, and the same fault on more than one wheel counts once.

Data sources and methodology
| Figures | Source | Period | Records | Updated |

| MOT defects and advisories | Anonymised MOT tests and results Driver and Vehicle Standards Agency Derived statistics UK Motoring | 2025 | 74,783 MOT tests | 19 September 2026 |
- Shares for defects are of failed tests; shares for advisories are of all tests. A test can carry several defects, so shares add to more than 100%.
- The expected share is what an average car of the same registration years records, weighted by where this model’s failures fall. Where an item is outside the national figures for a year, the smallest share those figures show is used in its place, which is an upper bound, so the comparison never overstates a model’s problems. No expectation is published where less than 80% of the model’s failures can be compared.
- Great Britain only: DVSA does not run MOT testing in Northern Ireland. Cars under three years old are not tested.
- The descriptions of what each part does are general and the same on every model. Every figure comes from the MOT data.
