Wiper and visibility defects fail the Citroen e-C4 2.2× as often as they fail a petrol or diesel car

1,413 inspections in a single year make the E-C4 a modestly documented electric car in the data. Tyres cause 28.2% of its failures; visibility take 2.2× the share they take on petrol and diesel cars of the same age.

The cheapest failure on the list

Visibility take 26.5% of the defects that fail this car, 2.2× the share seen on petrol and diesel cars of the same age. The most common item in that group is "Wiper blade missing or obviously not clearing the windscreen", recorded 45 times in 2024.

SECTION // VISIBILITY CONCENTRATIONYear 3 crossover

Where the curve bends

The crossover with petrol happens around year 3. From there the E-C4's failure rate climbs faster than the petrol fleet, and the defect list explains why.

DEFECT CONCENTRATION IN FAILED TESTS:
E-C4 visibility share26.5%
Wider fleet average11.9%

The single most common item on a E-C4 certificate is "A tyre seriously damaged", recorded 51 times.

Buyer's protocolPre-purchase checklist

What to check

Check tyre age and tread across the full width, inner edge included. Electric cars wear tyres faster; a cheap mismatched set on a used car tells you how it was run. Trivial to fix, but a car advertised with worn wipers and a fresh failure certificate tells you how it was maintained. Have the suspension joints, bushes and springs checked on a lift. On this car it is a leading cause of failure and it is not visible from the outside. Check the washers reach the screen. It fails the test and it is a thirty-second check. Ask for the full MOT history by registration on the free DVSA service: advisories are next year's failures.

    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
    • 1,413 inspections in 2024 make this one of the adequately-documented electric cars in the data.
    • Visibility take 2.2× the share of failures they take on petrol and diesel cars of the same age.
    • It ranks 60 of 81 electric cars by first-time failure rate.
    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.
