2025 MOT results
DS DS3 common problems
The most common reason a DS DS3 fails its MOT is a broken coil spring, on 21.4% of its 11,554 failed tests in 2025. Against other cars of the same age, 7 faults stand out, the widest gaps being: a split joint boot at 20.7% of failures against 3.1% expected; a sidelight out at 10.6% of failures against 3.4% expected; a worn steering or suspension joint at 6.6% of failures against 2.5% expected.

What fails a DS DS3 MOT
Each bar is the share of failed DS DS3 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 |
|---|---|
| Coil spring: fractured or broken Suspension | 21.4% |
| Drive shafts: constant velocity boot split or insecure, no longer prevents the ingress of dirt Body, chassis, structure | 20.7% |
| Position lamp: not working Lamps, reflectors and electrical equipment | 10.6% |
| Headlamp: not working on dipped beam Lamps, reflectors and electrical equipment | 8.9% |
| Tyres: tread depth below requirements of 1.6mm Tyres | 8.5% |
| Wipers: does not clear the windscreen effectively Visibility | 7.3% |
| Track rod end: ball joint has excessive play Steering | 6.6% |
| Brake pads: less than 1.5 mm thick Brakes | 5.2% |
| Headlamp aim: projected beam image is obviously incorrect Lamps, reflectors and electrical equipment | 5.0% |
| Brake discs: significantly and obviously worn Brakes | 4.5% |
| Headlamp aim: too low Lamps, reflectors and electrical equipment | 4.4% |
| Suspension arms: ball joint excessively worn Suspension | 4.4% |

Broken coil spring
21.4% of failures 8.8% expected 2.4 times as often
A broken suspension spring, which usually snaps in the bottom coil and often fails on both sides within a year.
Look at each corner for a sagging ride height, and listen for a knock over speed bumps.
-
Split joint boot
20.7% of failures 3.1% expected 6.7 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.
-
Sidelight out
10.6% of failures 3.4% expected 3.1 times as often
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.
-
Headlamp out
8.9% of failures 4.3% expected 2.1 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.
-
Tyre worn below the legal limit
8.5% of failures 9.5% expected about as expected
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.
-
Wiper blades that do not clear the screen
7.3% of failures 6.9% expected about as expected
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.
Which parts of the car fail
Lamps, reflectors and electrical equipment is the area that most often fails a DS DS3, on 34.8% of failed tests. The widest gap against cars of the same registration years is body, chassis, structure, on 26.5% against 6.3% expected.

What testers warn about
54.3% of DS DS3 tests ended with at least one advisory: a fault the tester found that did not fail the test. On DS DS3s, 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 | 17.8% |
| Brake discs: worn, pitted or scored, but not seriously weakened Brakes | 17.3% |
| Tyres: slightly damaged or cracking or perishing Tyres | 11.8% |
| Exhaust system: mounting defective Body, chassis, structure | 7.0% |
| Brake pads: wearing thin Brakes | 6.9% |
| Suspension arms: pin or bush worn but not resulting in excessive movement Suspension | 5.9% |
| Engine oil leak, but not excessive Noise, emissions and leaks | 4.9% |
| Brake discs: worn, but not excessively Brakes | 4.8% |
| Track rod end: ball joint has slight play Steering | 2.4% |
| Service brake performance: binding but not excessively Brakes | 2.3% |
| Exhaust system: minor leak of exhaust gases Body, chassis, structure | 2.0% |
| Nail in tyre Non-component advisories | 2.0% |

DS DS3 problems: common questions
What is the most common problem with a DS DS3?
Of the faults that fail an MOT, “Coil spring: fractured or broken” is the most common: it appears on 21.4% of failed DS DS3 tests. Across categories, lamps, reflectors and electrical equipment is the area that most often fails one, on 34.8% of failed tests.
How often does a DS DS3 fail its MOT?
34.1% of DS DS3 tests in 2025 were not passed first time, from 33,881 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 23 out of 100, where 50 is as expected.
Does anything fail more often on a DS DS3 than on other cars?
Yes. “Drive shafts: constant velocity boot split or insecure, no longer prevents the ingress of dirt” appears on 20.7% of its failures against 3.1% for cars of the same age, and “Position lamp: not working” appears on 10.6% of its failures against 3.4% 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 DS DS3 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.
