BMW X3 G01 (2017 – 2024)

Reliability score : 8.8/10

The third-generation BMW X3 (code name G01) marks a major turning point compared to its predecessor (F25). Based on the modular CLAR platform, it offers transformed road handling, an interior finish worthy of the upper segment (close to the X5), and remarkable sound insulation. Launched in late 2017, it benefited from a mid-cycle refresh (LCI - Life Cycle Impulse) in summer 2021, bringing mild hybridization (48V MHEV) to almost all internal combustion engines, an updated infotainment system (iDrive 7), and aesthetic tweaks. Gasoline Focus: The G01's gasoline engines are based on the modular 'B' engine family (B48 for 4-cylinders, B58 for 6-cylinders). These blocks have proven to be among the most reliable engines ever produced by BMW, erasing the severe timing chain and high-pressure pump

✅ Strengths

Exceptional reliability of gasoline engines (B48 and especially B58)
Significantly improved interior finish quality and sound insulation
Dynamic road handling for an SUV of this weight
Highly ergonomic and responsive iDrive (6 and 7) infotainment system
Perfect ZF 8-speed automatic gearbox (Steptronic)

⚠️ Weaknesses

Fragile active grille shutters (block and illuminate the engine light)
Massive and anxiety-inducing recall campaigns on Diesel engines (EGR)
Extreme sensitivity of the xDrive transfer case to tire circumference
Firm damping, especially with M Sport suspension and 20/21-inch wheels
High maintenance cost at official BMW dealerships

🎯 Verdict

The BMW X3 G01 is undoubtedly one of the most accomplished and reliable premium SUVs of its generation, provided you choose a gasoline engine. The B48 (20i/30i) and especially the masterful 6-cylinder B58 (M40i) engines offer rare peace of mind in the modern premium segment. Diesel versions, although powerful and economical, are marred by the EGR cooler scandal, which requires strict vigilance. For a used purchase, prioritize a gasoline model (M40i if the budget allows, it's a future collector's item) with a rigorous service history and BMW-approved tires to preserve the xDrive transmission.
