Summary

The 2018 BMW 530e xDrive iPerformance, while generally a reliable and enjoyable vehicle, does have its share of potential issues. The most concerning are related to the high-voltage battery and the charging system, which can be expensive to repair. Electrical gremlins in the iDrive system and adaptive headlights are also relatively common. Overall, while the severity of potential issues varies, owners should be prepared for potentially costly repairs, especially as the vehicle ages.
