Across 38,393 MOT tests of the Vauxhall Viva in the DfT's 2023 MOT data (initial tests, retests excluded), 14.8% failed — about 1 in 7. The parts that fail most are tyres (5.3% of tests), wipers, windscreen and mirrors (4.8%), lights and electrics (2.8%), brakes (1.7%) and suspension (1.5%).
Allowing for age and mileage, the Vauxhall Viva has 4% fewer 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.
