Most Common MINI Convertible (F57) Faults & Repair Costs
Upper Engine Mount Failure
The same hydraulic upper mount issue seen on the F56 hatch creates extra vibration and drivetrain movement.

Front Suspension Bush Wear
Heavy wheels and UK potholes wear front bushes and drop links, causing the familiar MINI knock from the front axle.

Water ingress from blocked drains or A-pillar seals can damage the BDC module, leading to total electrical failure.
