BMW X4 (G02) Common Problems & Reliability
The G02 X4 is the sleek, coupe-SUV sibling to the highly acclaimed G01 X3, offering aggressive styling and a remarkably well-built interior. Positioned against the Mercedes GLC Coupe, it trades some practicality for immense road presence and sharper handling. It is highly reliable, sharing the excellent B-series engines and robust electronics of the X3, though it suffers from the same minor cooling and sensor niggles. It perfectly suits buyers wanting a premium, sporty-looking SUV who value dynamic driving over outright cargo capacity.
