Toyota Aygo Mk1 (2005–2014): what fails at MOT
Across 110,296 MOT tests of the Toyota Aygo Mk1 (2005–2014) in the DfT's 2023 MOT data (initial tests, retests excluded), 36.0% failed — about 1 in 3. The parts that fail most are lights and electrics (17.6% of tests), brakes (11.7%), suspension (9.0%), tyres (6.3%) and body, chassis and structure (5.0%).
Allowing for age and mileage, the Aygo Mk1 has 5% more MOT failures than the average car of the same age and mileage. That puts it last of the two Toyota Aygo generations on MOT results; the Aygo Mk2 (2014–2022) does best.
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.
