Steering (12 complaints on the 2018): check for a steering warning light, heavy or notchy steering at parking speed, and clunks over bumps.

Service brakes (7 complaints on the 2018): check pedal feel, pulling and grinding, look at rotor and pad wear, and ask when the brake fluid was last changed.
Engine (5 complaints on the 2018): 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 (5 complaints on the 2018): 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.
