Across 21,093 MOT tests of the Citroen C4 Cactus in the DfT's 2023 MOT data (initial tests, retests excluded), 24.1% failed — about 1 in 4. The parts that fail most are lights and electrics (8.5% of tests), wipers, windscreen and mirrors (7.9%), tyres (5.4%), body, chassis and structure (4.0%) and brakes (3.8%).
Allowing for age and mileage, the Citroen C4 Cactus has 49% more MOT failures than the average car of the same age and mileage.
The MOT checks safety and emissions items — brakes, suspension, steering, lights, tyres, body structure and exhaust emissions. It does not test engines, gearboxes or most electronics, so those faults only show up here when they cause an emissions failure or a leak.
