BMW Série 5 G30/G31 (2017 – 2023)

Reliability score : 8.2/10

The BMW 5 Series G30 (Sedan) and G31 (Touring) represent a significant leap in quality and reliability over the previous F10 generation. Built on the modular CLAR platform, it shed up to 100 kg while vastly improving chassis dynamics and interior technology. Introduced in 2017, it received a comprehensive Life Cycle Impulse (LCI / facelift) in mid-2020, which brought sharper styling, updated iDrive 7.0, and widespread integration of 48V Mild-Hybrid (MHEV) technology across almost all four- and six-cylinder engines. The diesel engines (B47 4-cylinder and B57 6-cylinder) are widely considered among the best in the industry for their blend of performance, refinement, and fuel economy. Overall, the G30/G31 is highly regarded as one of the most reliable modern luxury cars, provided the notoriou

✅ Strengths

Exceptional build quality and interior materials
B57 (3.0d) and B58 (3.0i) 6-cylinder engines are industry benchmarks
Class-leading infotainment system (iDrive 7.0)
Superb balance between ride comfort and handling dynamics
Excellent sound insulation, especially with acoustic glass option
ZF 8-speed automatic transmission is flawless

⚠️ Weaknesses

EGR cooler issues on diesel engines (major recall)
xDrive transfer case sensitivity to tire wear
Rear air suspension on G31 Touring requires maintenance
Active grille shutters (radiator blinds) prone to failure
Steering lacks the hydraulic feel of older BMW generations
High repair costs for complex models (M550d, M550i, PHEVs)

🎯 Verdict

The BMW 5 Series G30/G31 is arguably the best executive car of its generation. BMW learned from the mistakes of the F10, resulting in a highly reliable platform. If you are looking at the diesel models, the 530d (B57) is the absolute sweet spot, offering sports-car torque with economy-car fuel consumption. The 520d (B47) is perfect for sensible daily commuting. Crucial Advice: Do not buy a diesel G30 without verifying the EGR cooler recall status. Avoid the M550d unless you have a comprehensive warranty. For maximum longevity, halve BMW's recommended oil change intervals and ensure strict tire maintenance on xDrive models.
