Summary:

The 2014 BMW 650i Gran Coupe offers impressive performance and luxury, but it has experienced some issues. Engine-related problems, such as valve stem seal failure and timing chain tensioner failure, can be costly to repair. Transmission issues, including mechatronic unit failure and torque converter shudder, can also impact drivability.
