The BMW 5 Series G30 (Sedan) and G31 (Touring) represent a significant leap in reliability compared to their predecessors (F10/F11). By transitioning entirely to the modular 'B-Series' engine family (B47/B48/B57/B58), BMW resolved many of the timing chain and oil consumption issues that plagued the older N-Series engines. Built on the CLAR platform, the G30/G31 is lighter, stiffer, and features highly advanced electronics. It is widely regarded by independent experts, TÜV, and DEKRA as one of the most reliable premium executive cars of its generation. The ZF 8-speed automatic transmission (standard on almost all models) is virtually bulletproof if serviced correctly.

The BMW 5 Series G30/G31 is arguably the most reliable premium executive car of its generation, provided you choose the right engine. BMW's shift to the B-series modular engines paid massive dividends in dependability. The 540i (B58) is the absolute sweet spot, offering sports-car performance with incredible reliability. For high-mileage drivers, the 520d or 530d remain excellent choices, provided the EGR cooler recall has been performed. Buyers should be cautious with early PHEVs and V8 models out of warranty. Overall, a well-maintained G30/G31 is a highly recommended purchase.
