Summary

The 2016 BMW M235i is a generally reliable performance car, but owners should be aware of potential issues. Engine issues like oil leaks, VANOS solenoid failures, and charge pipe cracks are common. Transmission issues depend on the chosen transmission, but the automatic transmission can suffer from mechatronic sleeve leaks. Suspension components may wear over time. While some issues can be relatively inexpensive to fix, others, especially those involving the transmission or more complex engine repairs, can be costly. Pre-purchase inspections are highly recommended to identify potential problems before buying.
