Chery Tiggo 8 Pro battery drain overnight — 12V auxiliary
Vehicle fails to start after being parked overnight or for several days. The 12V auxiliary battery drains due to a parasitic current draw from the infotainment system staying active after the vehicle is locked. A software update addresses the issue on most models. A battery isolator switch provides a practical workaround for owners who park the vehicle for extended periods.
