What to check on a used 2021 BMW X3
Electrical system (35 complaints on the 2021): test every light, window, lock, the infotainment screen and the charging system, and have the car scanned for stored fault codes.
Engine (24 complaints on the 2021): cold-start it yourself and listen for ticking or knocking; check for oil leaks, low coolant and a lit check-engine light, and ask for oil-change records.
Structure (11 complaints on the 2021): look under the car for rust or damage around the subframe and rockers, open every door and the liftgate, and check panel gaps for signs of repair.
Speed control / throttle (9 complaints on the 2021): check for surging, hesitation or a reduced-power warning, and test cruise control.
Service brakes (6 complaints on the 2021): check pedal feel, pulling and grinding, look at rotor and pad wear, and ask when the brake fluid was last changed.
