What to check on a used 2020 Honda Odyssey
Forward collision avoidance (187 complaints on the 2020): ask about false automatic-braking events and look for driver-assist warning messages.
Electrical system (174 complaints on the 2020): test every light, window, lock, the infotainment screen and the charging system, and have the car scanned for stored fault codes.
Lane departure (129 complaints on the 2020): on the test drive, check that lane-keeping assist neither pulls unexpectedly nor throws warnings.
Engine (71 complaints on the 2020): 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 (32 complaints on the 2020): 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.
