Hi guys.I am new to this forum and wonder if anyone can help.I have an optima isg 3 automatic 2019 plate. I have had issues lately that after I lock the car and after an hour or so the front windows open for no apparent reason.I don't know if the car unlocks at the time then relocks itself.This has only happened in sub zero temperatures.Also today I could only get one door unlocked with the fob.Passenger door.The central locking console on the door has a red flashing light when driving.Anything I can do?cheers.
