Summary

The 2014 BMW 750Li xDrive offers a luxurious driving experience but can be prone to several issues, particularly related to the engine, transmission, suspension, and electronics. Oil and coolant leaks in the engine are relatively common and can be costly to repair. The air suspension can also fail, leading to expensive replacements. Electrical issues with the iDrive system and battery drain can also arise. Due to the age of this vehicle, all rubber parts will need to be inspected and should be replaced.
