BMW X5 G05 (2018 – 2025)

Reliability score : 8.6/10

The fourth-generation BMW X5 (G05), launched in late 2018, is based on the modular CLAR platform. It marks a significant leap forward in terms of interior finish, comfort (air suspension optional or standard depending on the version), and onboard technologies compared to the F15 generation. In 2023, the model received a mid-cycle refresh (LCI - Life Cycle Impulse) introducing the BMW Curved Display (iDrive 8/8.5), generalized 48V mild hybridization on internal combustion engines (including diesels), and new powertrains (50e, M60i). Although the market is massively shifting towards plug-in hybrids (45e/50e), diesel powertrains (B57 6-cylinder family) remain the preferred choice for high-mileage drivers and those who tow, offering an exceptional performance/consumption ratio and very high re

✅ Strengths

Exceptional driving pleasure and fuel efficiency of the 6-cylinder diesel (30d/40d)
Very high-quality interior finish and sound insulation
Ultra-responsive and intuitive iDrive infotainment system (7.0 and 8.0)
Dynamic road handling for an SUV of this size (especially with rear-wheel steering)
Overall reliability of the 6-cylinder engines (B57 diesel and B58 petrol)

⚠️ Weaknesses

Very high weight (accelerates wear of brakes, tires, and running gear)
Extreme sensitivity of the xDrive transfer case to tire wear differences
Bulkiness in the city (over 2 meters wide with mirrors)
Cost of maintenance and spare parts in the official network
Disappearance of physical climate control buttons on LCI versions (2023+)

🎯 Verdict

The BMW X5 G05 is undoubtedly one of the best premium SUVs of its generation. While the market is pushing towards plug-in hybrids (45e/50e), the 30d and 40d diesel versions (B57 engine) remain the most pragmatic and reliable choice for high-mileage drivers. This engine combines quiet power with surprisingly low consumption for a 2.2-ton vehicle. Mechanical reliability is excellent, provided that the EGR cooler recall has been performed and the golden rules of the xDrive system (4 identical and star-marked tires) are strictly followed. Avoid the M50d if you fear astronomical maintenance bills, and opt for a well-optioned 30d.
