For the twin-turbo V12 (M275) and later V8s (M157), cylinder wall scoring and other turbo-related defects are mentioned as known risks. Frequency: recurrent.
Dynamic multi-contour seat failures — optional seats are very expensive to repair when their numerous adjustments fail. Frequency: recurrent.
Rust — mentioned as a concern for vehicles in certain climates, particularly underneath the car and around the rear axle. Frequency: isolated.
