What to check on a used 2026 Porsche Cayenne
Forward collision avoidance (4 complaints on the 2026): ask about false automatic-braking events and look for driver-assist warning messages.
Electrical system (2 complaints on the 2026): test every light, window, lock, the infotainment screen and the charging system, and have the car scanned for stored fault codes.
Lane departure (2 complaints on the 2026): on the test drive, check that lane-keeping assist neither pulls unexpectedly nor throws warnings.
Backup camera / back-over prevention (1 complaint on the 2026): shift into reverse several times and make sure the camera image comes up quickly and clearly.
Powertrain / transmission (1 complaint on the 2026): 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.
