2025 MOT results
Peugeot RCZ common problems
The most common reason a Peugeot RCZ fails its MOT is a broken coil spring, on 23.6% of its 3,798 failed tests in 2025. Against other cars of the same age, 7 faults stand out, the widest gaps being: a lighting fault at 4.3% of failures against 1.3% expected; a split joint boot at 13.7% of failures against 4.8% expected; a broken coil spring at 23.6% of failures against 11.2% expected.

What fails a Peugeot RCZ MOT
Each bar is the share of failed Peugeot RCZ 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 (11 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 | 23.6% |
| Drive shafts: constant velocity boot split or insecure, no longer prevents the ingress of dirt Body, chassis, structure | 13.7% |
| Stop lamp: not working Lamps, reflectors and electrical equipment | 11.0% |
| Malfunction indicator lamp: inoperative or indicates a malfunction Noise, emissions and leaks | 9.4% |
| Headlamp aim: projected beam image is obviously incorrect Lamps, reflectors and electrical equipment | 8.7% |
| Tyres: tread depth below requirements of 1.6mm Tyres | 7.9% |
| Position lamp: not working Lamps, reflectors and electrical equipment | 6.2% |
| Headlamp: not working on dipped beam Lamps, reflectors and electrical equipment | 5.9% |
| Headlamp: insecure Lamps, reflectors and electrical equipment | 5.0% |
| Headlamp aim: too high Lamps, reflectors and electrical equipment | 4.4% |
| Suspension arms: ball joint excessively worn Suspension | 4.4% |
| Anti-lock braking system: warning lamp indicates an ABS fault Brakes | 4.3% |

Broken coil spring
23.6% of failures 11.2% expected 2.1 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
13.7% of failures 4.8% expected 2.9 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
11.0% of failures 7.3% expected 1.5 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.
-
Engine management light on
9.4% of failures 4.9% expected 1.9 times as often
The engine management light is on, or has been disconnected. Either fails the test.
A cheap code reader on the diagnostic socket will say what the car has stored before you pay for a test.
-
Headlamp aim out of line
8.7% of failures 4.5% expected 1.9 times as often
The beam pattern points too high, too low, or in the wrong place, so it either dazzles others or lights too little 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.
-
Tyre worn below the legal limit
7.9% of failures 7.8% 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.
Which parts of the car fail
Lamps, reflectors and electrical equipment is the area that most often fails a Peugeot RCZ, on 42.5% of failed tests. The widest gap against cars of the same registration years is noise, emissions and leaks, on 20.2% against 10.6% expected.

What testers warn about
57.0% of Peugeot RCZ tests ended with at least one advisory: a fault the tester found that did not fail the test. On Peugeot RCZ cars, 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 | 19.4% |
| Brake discs: worn, pitted or scored, but not seriously weakened Brakes | 15.9% |
| Engine oil leak, but not excessive Noise, emissions and leaks | 13.2% |
| Tyres: slightly damaged or cracking or perishing Tyres | 9.6% |
| Suspension arms: pin or bush worn but not resulting in excessive movement Suspension | 7.6% |
| Brake pads: wearing thin Brakes | 6.7% |
| Coil spring: corroded Suspension | 3.0% |
| Brake discs: worn, but not excessively Brakes | 2.7% |
| Tyres: cut but not deep enough to reach the ply or cords Tyres | 2.5% |
| Suspension arms: ball joint has slight play Suspension | 2.0% |
| Nail in tyre Non-component advisories | 2.0% |
| Flexible brake hoses: slight corrosion to ferrule Brakes | 1.9% |

Peugeot RCZ problems: common questions
What is the most common problem with a Peugeot RCZ?
Of the faults that fail an MOT, “Coil spring: fractured or broken” is the most common: it appears on 23.6% of failed Peugeot RCZ tests. Across categories, lamps, reflectors and electrical equipment is the area that most often fails one, on 42.5% of failed tests.
How often does a Peugeot RCZ fail its MOT?
36.8% of Peugeot RCZ tests in 2025 were not passed first time, from 10,309 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 44 out of 100, where 50 is as expected.
Does anything fail more often on a Peugeot RCZ than on other cars?
Yes. “Anti-lock braking system: warning lamp indicates an ABS fault” appears on 4.3% of its failures against 1.3% for cars of the same age, and “Drive shafts: constant velocity boot split or insecure, no longer prevents the ingress of dirt” appears on 13.7% of its failures against 4.8% 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 Peugeot RCZ 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 | 10,309 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.
