Across 7,004 MOT tests of the Porsche Panamera in the DfT's 2023 MOT data (initial tests, retests excluded), 12.7% failed — about 1 in 8. The parts that fail most are tyres (7.3% of tests), lights and electrics (2.2%), suspension (1.8%), brakes (1.3%) and wipers, windscreen and mirrors (1.0%).
Allowing for age and mileage, the Porsche Panamera has 47% 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.
