Summary

The 2019 BMW 640i xDrive Gran Coupe offers a blend of luxury and performance. However, owners should be aware of potential issues with the engine (oil/coolant leaks), transmission (rough shifting, mechatronic failure), suspension (adaptive damper/air suspension problems), and electrical system (iDrive glitches, battery drain). While some issues may be relatively minor and inexpensive to fix, others can be costly, especially those involving the transmission or adaptive suspension. Regular maintenance and prompt attention to any warning signs can help mitigate these risks.
