Summary Verdict

The 2010 BMW X6, while offering a compelling driving experience, presents a mixed reliability profile. Owners are most likely to encounter issues related to its powerful turbocharged engines, particularly the V8, which can suffer from significant oil consumption and turbocharger problems. Transmission issues, though less common, can be costly to repair. The advanced suspension systems, while enhancing handling, are also a potential source of expensive leaks and component failures. Electrical gremlins, especially within the iDrive system and parasitic battery drains, are not uncommon. Addressing these potential issues proactively through diligent maintenance and prompt repairs is key to maintaining the X6’s performance and value.
