Chevrolet Matiz common problems
The most common reason a Chevrolet Matiz fails its MOT is a sidelight out, on 13.5% of its 4,043 failed tests in 2025. Against other cars of the same age, 6 faults stand out, the widest gaps being: a weak or uneven footbrake at 8.5% of failures against 2.0% expected; structural corrosion at 9.3% of failures against 3.7% expected; corroded brake pipes at 6.8% of failures against 2.8% expected.

What fails a Chevrolet Matiz MOT
Each bar is the share of failed Chevrolet Matiz 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 |
|---|---|
| Position lamp: not working Lamps, reflectors and electrical equipment | 13.5% |
| Suspension arms: ball joint excessively worn Suspension | 12.6% |
| Wipers: does not clear the windscreen effectively Visibility | 10.6% |
| Tyres: tread depth below requirements of 1.6mm Tyres | 9.5% |
| Component mounting prescribed area excessively corroded significantly reducing structural strength Suspension | 9.3% |
| Stop lamp: not working Lamps, reflectors and electrical equipment | 9.2% |
| Service brake imbalance: across an axle Brakes | 8.5% |
| Headlamp: not working on dipped beam Lamps, reflectors and electrical equipment | 7.8% |
| Headlamp aim: projected beam image is obviously incorrect Lamps, reflectors and electrical equipment | 7.6% |
| Service brake performance: excessively binding Brakes | 6.8% |
| Rigid brake pipes: excessively corroded Brakes | 6.8% |
| Exhaust system: major leak of exhaust gases Body, chassis, structure | 6.5% |

-
Sidelight out
13.5% of failures 13.9% expected about as expected
A sidelight, also called a position lamp, not working. It marks the width of the car at night.
Walk round the car with the lights on and the hazards going; these are the cheapest failures to avoid.
-
Worn steering or suspension joint
12.6% of failures 6.0% expected 2.1 times as often
Play in a steering or suspension joint, where a worn ball and socket lets the wheel move where it should not.
A knock at low speed over rough ground, or vague steering, is the usual warning.
-
Wiper blades that do not clear the screen
10.6% of failures 5.5% expected 1.9 times as 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.
-
Tyre worn below the legal limit
9.5% of failures 6.9% 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.
-
Structural corrosion
9.3% of failures 3.7% expected 2.5 times as often
Corrosion in a structural area near a suspension, steering or seat belt mounting, which is a serious failure.
Look at the inner sills, rear spring seats and subframe mounts on cars over about 12 years old.
-
Brake light out
9.2% of failures 9.3% expected about as expected
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
Lamps, reflectors and electrical equipment is the area that most often fails a Chevrolet Matiz, on 47.1% of failed tests. The widest gap against cars of the same registration years is brakes, on 33.2% against 25.3% expected.

What testers warn about
73.4% of Chevrolet Matiz tests ended with at least one advisory: a fault the tester found that did not fail the test. On Chevrolet Matizes, 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 | 21.1% |
| Rigid brake pipes: corroded, covered in grease or other material Brakes | 20.6% |
| Engine oil leak, but not excessive Noise, emissions and leaks | 13.4% |
| Tyres: slightly damaged or cracking or perishing Tyres | 12.0% |
| Wheel bearings: slight play Suspension | 8.5% |
| Registration plates: deteriorated but not likely to be misread Identification of the vehicle | 7.9% |
| Brake discs: worn, pitted or scored, but not seriously weakened Brakes | 7.5% |
| Exhaust system: minor leak of exhaust gases Body, chassis, structure | 7.2% |
| Suspension arm: corroded but not seriously weakened Suspension | 5.5% |
| Service brake performance: binding but not excessively Brakes | 5.5% |
| Shock absorbers: slightly worn bush Suspension | 5.4% |
| Macpherson strut: pin or bush worn but not resulting in excessive movement Suspension | 5.2% |

Chevrolet Matiz problems: common questions
What is the most common problem with a Chevrolet Matiz?
Of the faults that fail an MOT, “Position lamp: not working” is the most common: it appears on 13.5% of failed Chevrolet Matiz tests. Across categories, lamps, reflectors and electrical equipment is the area that most often fails one, on 47.1% of failed tests.
How often does a Chevrolet Matiz fail its MOT?
49.8% of Chevrolet Matiz tests in 2025 were not passed first time, from 8,112 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 34 out of 100, where 50 is as expected.
Does anything fail more often on a Chevrolet Matiz than on other cars?
Yes. “Service brake imbalance: across an axle” appears on 8.5% of its failures against 2.0% for cars of the same age, and “Component mounting prescribed area excessively corroded significantly reducing structural strength” appears on 9.3% of its failures against 3.7% 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 Chevrolet Matiz 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 |

- 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.
