Summary Verdict

The 2019 BMW X5 (G05) generally offers good reliability, especially with its well-regarded powertrains. However, owners should be aware of potential issues, particularly with the more complex options like the V8 engine and adaptive air suspension. Common concerns include coolant leaks and PCV valve issues on the inline-six, and oil consumption or turbo problems on the V8. The ZF 8-speed automatic transmission is robust but can experience mechatronic unit or torque converter failures. Electrical gremlins, primarily software-related in the iDrive system, and battery drain issues are also noted. For those opting for advanced suspension systems, air spring leaks are a possibility. Regular maintenance and prompt attention to warning signs are crucial for maintaining the X5’s long-term reliability and performance.
