Reliability snapshot
The G11 7 Series uses BMW's modular B-series and later V8 engines and carbon-core body technology. It is a technology-heavy flagship, so reported items skew toward electronics/software and comfort features, alongside air-suspension and routine cooling maintenance. The B58 six and B57 diesel are well regarded; N63 V8 cars need the usual attention to that engine. Following the service schedule and keeping software current are the main needs.
