Lighting faults fail the Peugeot Partner 2.4× as often as they fail a petrol or diesel car

778 inspections in a single year make the PARTNER a modestly documented electric car in the data. Lighting cause 39.2% of its failures; lighting take 2.4× the share they take on petrol and diesel cars of the same age.

First-time test findings

The five-year vs seven-year picture

AT FIVE YEARS OLD5.2%

PARTNER failure rate. Petrol cars of the same age fail 10.7%.

AT SEVEN YEARS OLD6.6%

PARTNER failure rate, against 14.9% for petrol.

The Peugeot Partner fails 8.1% of first-time inspections. By 6 years that reaches 18.4%. Lighting cause 39.2% of its failures.

FIGURE 2 // HEADLAMP UNIT13 certificates in 2024

The lamp that fails the test

Lighting take 39.2% of the defects that fail this car, 2.4× the share seen on petrol and diesel cars of the same age. The most common item in that group is "Stop lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning", recorded 13 times in 2024.

SECTION // LIGHTING CONCENTRATIONYear 6 crossover

Where the curve bends

The crossover with petrol happens around year 6. From there the PARTNER's failure rate climbs faster than the petrol fleet, and the defect list explains why.

DEFECT CONCENTRATION IN FAILED TESTS:
PARTNER lighting share39.2%
Petrol and diesel average16.5%

The single most common item on a PARTNER certificate is "Windscreen washers not working or not providing sufficient fluid to clear the windscreen", recorded 15 times.

Buyer's protocolPre-purchase checklist

What to check

Check the washers reach the screen. It fails the test and it is a thirty-second check. Check headlamp aim and every lamp before the test. It is the cheapest failure on the list and the easiest to avoid. Ask when the brakes were last stripped and cleaned. Regenerative braking barely wears the pads, so discs and calipers corrode and seize instead. Ask for the full MOT history by registration on the free DVSA service: advisories are next year's failures.

3 inspection points:
✓ Washer reach
✓ Headlamp aim and every lamp
✓ Rear caliper drag and disc lip

    OWNER REPORTS // MATCHED TO RECORDED DEFECTS0 read · 0 matched
    No owner discussion has been matched to this car's recorded defects yet. Reports are re-collected every quarter; the figures on this page do not depend on them.

    Summaries written by us, never quotes; every entry links to its source. Owner reports have no denominator and never feed the failure rate.

    Three things the data shows
    • 778 inspections in 2024 make this one of the adequately-documented electric cars in the data.
    • Lighting take 2.4× the share of failures they take on petrol and diesel cars of the same age.
    • Failure rate rises from 5.2% at 5 years to 18.4% at 6: a steep ageing curve.
    LIMITS // WHAT THE INSPECTION DOES NOT TELL YOU

    No battery health, no motor, no charging performance. The test covers brakes, suspension, steering, tyres, lights, visibility and structure. A car with a badly degraded battery passes as long as it stops and steers. Read this page as evidence about the chassis, not the powertrain. Cars are tested from their third year, so the newest model years are missing; every figure carries its sample size for that reason. Full methodology.
