Summary Verdict

The 2010 BMW 550i (E60) is a powerful luxury sedan with a generally solid mechanical foundation, particularly its V8 engine. However, owners should be aware of potential issues common to this model, primarily concerning oil leaks from gaskets, cooling system components, and the eccentric shaft sensor. Transmission reliability is good for the manual, but the automatic can experience fluid leaks and torque converter issues. Electrical gremlins, such as iDrive glitches and battery drain, are also noted. While not overwhelmingly problematic, these potential repairs can be costly due to the complexity and premium nature of the vehicle. Regular maintenance and prompt attention to early warning signs are crucial for maintaining the 550i’s performance and longevity.
