What to check on a used 2018 Porsche Panamera
Powertrain / transmission (4 complaints on the 2018): test-drive from cold through every gear and feel for slipping, harsh or delayed shifts and shudder; ask whether the transmission fluid has been serviced.
Engine (4 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.
Electrical system (3 complaints on the 2018): test every light, window, lock, the infotainment screen and the charging system, and have the car scanned for stored fault codes.
Suspension (1 complaint on the 2018): listen for clunks over bumps, look for leaking struts and check for uneven tire wear.
Service brakes (1 complaint on the 2018): check pedal feel, pulling and grinding, look at rotor and pad wear, and ask when the brake fluid was last changed.
