Across 26,751 MOT tests of the Porsche Macan in the DfT's 2023 MOT data (initial tests, retests excluded), 8.3% failed — about 1 in 12. The parts that fail most are tyres (3.6% of tests), lights and electrics (1.8%), brakes (0.9%), body, chassis and structure (0.8%) and wipers, windscreen and mirrors (0.7%).
Allowing for age and mileage, the Porsche Macan 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.
