2
Electrical Systemmoderate~50,000-80,000 mi

Various electronic modules, sensors (wheel speed, ABS), and iDrive system components can develop faults. Window regulators and door lock actuators are also common failures, causing erratic behavior.

3
Engine Oil Leaksmoderate~70,000-100,000 mi

Valve cover gaskets and oil filter housing gaskets are common culprits for oil leaks, which can lead to oil burning smells and eventual damage if neglected. Less severe than N-series engines but still present.
