Alfa Romeo Giulia common problems
The most common reason a Alfa Romeo Giulia fails its MOT is headlamp aim set too high, on 17.9% of its 1,065 failed tests in 2025. Against other cars of the same age, 4 faults stand out, the widest gaps being: headlamp aim set too high at 17.9% of failures against 3.7% expected; a worn steering or suspension joint at 2.3% of failures against 0.7% expected; a tyre worn through to the cords at 16.2% of failures against 6.5% expected.

What fails a Alfa Romeo Giulia MOT
Each bar is the share of failed Alfa Romeo Giulia 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 |
|---|---|
| Headlamp aim: too high Lamps, reflectors and electrical equipment | 17.9% |
| Tyres: ply or cords exposed Tyres | 16.2% |
| Tyres: tread depth below requirements of 1.6mm Tyres | 14.9% |
| Tyres: cut in excess of the requirements deep enough to reach the ply or cords Tyres | 8.0% |
| Brake pads: less than 1.5 mm thick Brakes | 7.8% |
| Headlamp aim: too low Lamps, reflectors and electrical equipment | 6.2% |
| Malfunction indicator lamp: inoperative or indicates a malfunction Noise, emissions and leaks | 6.0% |
| Tyres: bulge, caused by separation or partial failure of its structure Tyres | 4.5% |
| Washers: not working Visibility | 3.2% |
| Brake discs: significantly and obviously worn Brakes | 2.8% |
| Tyre pressure monitoring system: malfunctioning or obviously inoperative Tyres | 2.3% |
| Linkage ball joint excessively worn Suspension | 2.3% |

-
Headlamp aim set too high
17.9% of failures 3.7% expected 4.8 times as often
The dipped beam points higher than it should, which dazzles oncoming drivers.
Nothing to do at the roadside, but a garage resets the aim in minutes; a sagging suspension corner or a heavy boot load can throw it out.
-
Tyre worn through to the cords
16.2% of failures 6.5% expected 2.5 times as often
The tyre is worn or damaged far enough to expose the cords underneath, which is a dangerous defect.
Run a hand round the inner and outer walls of each tyre, which is where kerbing shows.
-
Tyre worn below the legal limit
14.9% of failures 10.5% 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.
-
Cut tyre
8.0% of failures 10.3% 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.
-
Worn brake pads
7.8% of failures 9.3% expected somewhat less 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.
-
Headlamp aim set too low
6.2% of failures 4.2% expected 1.5 times as often
The dipped beam points lower than it should, so it lights too little of the road.
Nothing to do at the roadside, but a garage resets the aim in minutes; a sagging suspension corner or a heavy boot load can throw it out.
Which parts of the car fail
Tyres is the area that most often fails a Alfa Romeo Giulia, on 44.5% of failed tests. That is also where it differs most from cars of the same registration years, which record 34.4%.

What testers warn about
36.3% of Alfa Romeo Giulia tests ended with at least one advisory: a fault the tester found that did not fail the test. On Alfa Romeo Giulias, 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 | 17.2% |
| Brake discs: worn, pitted or scored, but not seriously weakened Brakes | 10.5% |
| Brake pads: wearing thin Brakes | 7.8% |
| Linkage ball joint has slight play Suspension | 2.4% |
| Tyres: slightly damaged or cracking or perishing Tyres | 2.3% |
| Brake discs: worn, but not excessively Brakes | 2.1% |
| Shock absorbers: light misting of oil Suspension | 1.5% |
| Child seat fitted not allowing full inspection of adult belt Non-component advisories | 1.4% |
| Tyres: cut but not deep enough to reach the ply or cords Tyres | 1.4% |
| Nail in tyre Non-component advisories | 1.0% |
| Engine oil leak, but not excessive Noise, emissions and leaks | 1.0% |
| Tyres: slightly damaged Tyres | 0.6% |

Alfa Romeo Giulia problems: common questions
What is the most common problem with a Alfa Romeo Giulia?
Of the faults that fail an MOT, “Headlamp aim: too high” is the most common: it appears on 17.9% of failed Alfa Romeo Giulia tests. Across categories, tyres is the area that most often fails one, on 44.5% of failed tests.
How often does a Alfa Romeo Giulia fail its MOT?
14.3% of Alfa Romeo Giulia tests in 2025 were not passed first time, from 7,447 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 56 out of 100, where 50 is as expected.
Does anything fail more often on a Alfa Romeo Giulia than on other cars?
Yes. “Headlamp aim: too high” appears on 17.9% of its failures against 3.7% for cars of the same age, and “Linkage ball joint excessively worn” appears on 2.3% of its failures against 0.7% 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 Alfa Romeo Giulia 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.
