2025 MOT results
Toyota GT86 common problems
The most common reason a Toyota GT86 fails its MOT is a tyre worn below the legal limit, on 12.2% of its 1,084 failed tests in 2025. Against other cars of the same age, 5 faults stand out, the widest gaps being: a wheel bearings rough when rotated at 3.8% of failures against 0.7% expected; emissions above the limit at 9.2% of failures against 1.7% expected; a weak or uneven footbrake at 5.4% of failures against 2.4% expected.

What fails a Toyota GT86 MOT
Each bar is the share of failed Toyota GT86 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 | 12.2% |
| Catalyst emissions: lambda reading after 2nd fast idle outside specified limits Noise, emissions and leaks | 9.2% |
| Wipers: does not clear the windscreen effectively Visibility | 7.9% |
| Registration plate lamp(s): inoperative in the case of a single lamp or all lamps Lamps, reflectors and electrical equipment | 6.7% |
| Brake pads: less than 1.5 mm thick Brakes | 6.0% |
| Washers: provides insufficient washer liquid Visibility | 5.5% |
| Service brake performance: excessively binding Brakes | 5.4% |
| Tyres: ply or cords exposed Tyres | 4.9% |
| Coil spring: fractured or broken Suspension | 4.7% |
| Tyres: cut in excess of the requirements deep enough to reach the ply or cords Tyres | 4.4% |
| Exhaust system: major leak of exhaust gases Body, chassis, structure | 4.0% |
| Wheel bearings: rough when rotated Suspension | 3.8% |

Tyre worn below the legal limit
12.2% of failures 8.5% expected somewhat more 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.
-
Emissions above the limit
9.2% of failures 1.7% expected 5.4 times as often
The exhaust gases are outside the limits for the car, which can be the catalytic converter, a sensor, or simply a poor state of tune.
A long run before the test helps a catalyst get hot; a persistent failure usually needs a diagnosis.
-
Wiper blades that do not clear the screen
7.9% of failures 5.7% expected somewhat more often
Wiper blades that leave the windscreen smeared or streaked across the area the driver looks through.
Look for split or hardened rubber, and lift each blade to see whether it still sits flat.
-
Number plate lamp out
6.7% of failures 3.5% expected 1.9 times as often
The lamp over the rear number plate not working, so the plate cannot be read at night.
Walk round the car with the lights on and the hazards going; these are the cheapest failures to avoid.
-
Worn brake pads
6.0% of failures 7.0% expected about as expected
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.
-
Washers that do not work
5.5% of failures 4.7% expected somewhat more often
The washers cannot deliver enough liquid to clean the windscreen with the wipers.
Top the bottle up and check both jets reach the glass; the pump is often fine and the jet blocked.
Which parts of the car fail
Tyres is the area that most often fails a Toyota GT86, on 26.5% of failed tests. The widest gap against cars of the same registration years is noise, emissions and leaks, on 17.4% against 9.8% expected.

What testers warn about
37.1% of Toyota GT86 tests ended with at least one advisory: a fault the tester found that did not fail the test. On Toyota GT86s, 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 | 14.2% |
| Brake discs: worn, pitted or scored, but not seriously weakened Brakes | 6.7% |
| Brake pads: wearing thin Brakes | 6.0% |
| Tyres: slightly damaged or cracking or perishing Tyres | 5.8% |
| Service brake performance: binding but not excessively Brakes | 3.0% |
| Brake discs: worn, but not excessively Brakes | 2.2% |
| Coil spring: corroded Suspension | 1.8% |
| Registration plates: deteriorated but not likely to be misread Identification of the vehicle | 1.7% |
| Engine oil leak, but not excessive Noise, emissions and leaks | 1.5% |
| Exhaust system: minor leak of exhaust gases Body, chassis, structure | 1.3% |
| Sub-frame: corroded but not seriously weakened Suspension | 1.2% |
| Shock absorbers: light misting of oil Suspension | 1.2% |

Toyota GT86 problems: common questions
What is the most common problem with a Toyota GT86?
Of the faults that fail an MOT, “Tyres: tread depth below requirements of 1.6mm” is the most common: it appears on 12.2% of failed Toyota GT86 tests. Across categories, tyres is the area that most often fails one, on 26.5% of failed tests.
How often does a Toyota GT86 fail its MOT?
16.5% of Toyota GT86 tests in 2025 were not passed first time, from 6,589 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 70 out of 100, where 50 is as expected.
Does anything fail more often on a Toyota GT86 than on other cars?
Yes. “Wheel bearings: rough when rotated” appears on 3.8% of its failures against 0.7% for cars of the same age, and “Catalyst emissions: lambda reading after 2nd fast idle outside specified limits” appears on 9.2% of its failures against 1.7% 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 Toyota GT86 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.

- 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.
