Across 30,714 MOT tests of the Lexus CT in the DfT's 2023 MOT data (initial tests, retests excluded), 14.8% failed — about 1 in 7. The parts that fail most are lights and electrics (5.7% of tests), tyres (5.1%), wipers, windscreen and mirrors (3.1%), brakes (2.7%) and suspension (0.9%).
Allowing for age and mileage, the Lexus CT has 43% 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.
