Known faults, from the test record

Peugeot Rcz common problems

What fails on the Peugeot Rcz at MOT, which parts are behind it, and how each model year compares. From 10,309 DVSA test records.

Data updated

Quick answer

The Peugeot Rcz's most common MOT problems are coil springs, tyres, bulbs and lamps, recorded in 33.3%, 26.7% and 23.7% of failed tests respectively. By model year, 2015 cars pass most often (70.3%) and 2010 cars least (55.6%), though most of that gap is age. Every figure here is what testers recorded, not what owners reported.

A “common problems” list is usually a forum thread: whoever had the worst day writes the longest post. This one is built the other way, from every Peugeot Rcz that took an MOT last year and what the tester wrote down. It cannot see breakdowns, electrical gremlins or a gearbox that hunts, because the test does not check those. What it can see, it sees across 10,309 cars.

By component

What wears out on a Rcz

Failure items grouped by the part behind them, with the share of failed Peugeot Rcz tests recording each. A part can carry several DVSA wordings; they are listed beneath. One failed test often lists several items, so shares do not sum to 100%.

  1. 1.Coil springs

    33.3% of failed tests

    Springs fatigue and corrode where the coating chips, then snap, often at the bottom coil; potholes and salt accelerate it.

    • “A spring or spring component fractured or seriously weakened” — explained33.3%

    Across all cars, coil springs failures climb 20-fold between three and fifteen years, peaking at 12–14 years. How long coil springs last

  2. 2.Tyres

    26.7% of failed tests

    Tread wears with every mile and sidewalls age and take kerb damage; the legal minimum is 1.6 mm across the central three-quarters.

    • “Tyre tread depth not in accordance with the requirements” — explained12.6%
    • “A tyre seriously damaged” — explained5.0%
    • “A tyre cords visible or damaged” — explained4.8%
    • “A tyre seriously damaged” — explained2.7%

    Across all cars, tyres failures run at a similar rate at every age, because they are replaced on a cycle rather than wearing out with the car. How long tyres last

  3. 3.Bulbs and lamps

    23.7% of failed tests

    Filament bulbs simply expire; the cheapest and most avoidable failure on the test, and one of the most recorded.

    • “Stop lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning” — explained9.3%
    • “A lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning” — explained6.7%
    • “A headlamp or light source missing, inoperative or more than ½ not functioning in the case of LED” — explained4.5%
    • “A rear registration plate lamp or light source missing or inoperative in the case of a single lamp or all lamps” — explained3.2%

    Across all cars, bulbs and lamps failures climb 15-fold between three and fifteen years, peaking at 15+ years. How long bulbs and lamps last

  4. 4.Suspension bushes

    17.6% of failed tests

    Rubber bushes in arms and links perish and split with age and load; the most recorded suspension item on the test.

    • “A suspension pin, bush or joint excessively worn” — explained6.0%
    • “A suspension pin, bush or joint excessively worn” — explained6.0%
    • “A suspension pin, bush or joint excessively worn” — explained2.3%
    • “A suspension pin, bush or joint excessively worn” — explained1.6%

    Across all cars, suspension bushes failures climb 20-fold between three and fifteen years, peaking at 15+ years. How long suspension bushes last

  5. 5.Driveshaft gaiters

    16.7% of failed tests

    The rubber boot over each CV joint splits with age and flexing, then throws grease and lets grit destroy the joint.

    • “A transmission shaft constant velocity joint boot missing or no longer prevents the ingress of dirt etc” — explained16.7%

    Across all cars, driveshaft gaiters failures climb 21-fold between three and fifteen years, peaking at 15+ years. How long driveshaft gaiters last

  6. 6.Headlamp aim

    14.6% of failed tests

    Aim drifts with sagging suspension, a knocked lamp or a botched bulb change; adjustment, not a part.

    • “The aim of a headlamp is not within limits laid down in the requirements” — explained9.7%
    • “The aim of a headlamp is not within limits laid down in the requirements” — explained2.7%
    • “The aim of a headlamp is not within limits laid down in the requirements” — explained2.2%

  7. 7.Engine management

    9.9% of failed tests

    The MIL lamp lit is a failure in itself, whatever the stored code; the fault codes section explains what lies behind it.

    • “Engine MIL illuminated indicating a malfunction” — explained8.1%
    • “Engine MIL illuminated indicating a malfunction” — explained1.8%

  8. 8.Catalytic converter and emissions

    8.8% of failed tests

    Catalysts degrade with age and misfires; a failed emissions reading is usually the catalyst, a lambda sensor or a tired engine.

    • “Lambda coefficient outside the default limits or the range specified by the manufacturer” — explained3.7%
    • “Emissions levels exceed the manufacturer's specified limits” — explained2.6%
    • “Smoke opacity levels exceed the manufacturer's specified limit” — explained2.5%

By registration year

Rcz problems by year

MOT pass rate for Peugeot Rcz cars by the year they were first registered, from years with at least 1,000 tests. Every car in a row is the same age, so the rate is raw. Neighbouring years differ by a year of wear — a step of a point or two is age. The step at 2011, up 5.5 points, is larger than wear explains and most likely marks a change in the cars themselves.

201056%
201161%+5.5
201262%+0.6
201363%+1.7
201468%+4.3
201570%+2.6

Last column: change on the previous year, in points. Years registered within the last three years have not yet been tested and are not shown.

Common questions

What are the most common problems with a Peugeot Rcz?
Going by what fails the MOT, coil springs (recorded in 33.3% of failed tests), tyres (recorded in 26.7% of failed tests), and bulbs and lamps (recorded in 23.7% of failed tests). These are the items testers actually record across 10,309 tests, not reports from owners, so they describe what goes wrong at the point where it has to be fixed.
Which Peugeot Rcz year is the most reliable?
By MOT pass rate, Peugeot Rcz cars registered in 2015 do best at 70.3% and 2010 cars do worst at 55.6%. Most of that ordering is simply age — newer cars pass more — so read the year table for steps larger than a couple of points between neighbouring years; those mark a change in the cars rather than the calendar. The largest such step is at 2011, up 5.5 points on 2010.
Is the Peugeot Rcz reliable?
The Peugeot Rcz passes 63.2% of MOTs unadjusted; its fleet is too narrow in age or mileage for a fair national comparison. An MOT measures roadworthiness on the day rather than breakdowns or running costs, so this is a reliability measure in the narrow sense: how often the car meets the legal standard, and what stops it.
What should I check when buying a used Peugeot Rcz?
Start with what fails most: coil springs, tyres, bulbs and lamps. Then read the car's own MOT history for advisories carried year to year without repair — the model tells you what to expect, the history tells you whether this owner dealt with it.
