Across 7,608 MOT tests of the Lexus UX in the DfT's 2023 MOT data (initial tests, retests excluded), 5.7% failed — about 1 in 18. The parts that fail most are tyres (2.9% of tests), wipers, windscreen and mirrors (1.5%) and lights and electrics (1.3%).
Allowing for age and mileage, the Lexus UX has 53% 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.
