Summary

The 2017 BMW 340i GT xDrive offers a compelling blend of performance and practicality, but potential buyers should be aware of some common issues. Engine oil leaks and coolant leaks, while not always catastrophic, can lead to expensive repairs if neglected. Suspension issues specific to the GT model, particularly the rear air suspension, can also be costly to address. Electrical glitches, especially with the iDrive system, can be frustrating.
