Walked out of the house today and noticed my 2017 GC was running. I unlocked the door and it died only to start again. Then it died. Doors started locking and unlocking all while the fob is in my hand and not pressing any buttons. Opened couple of doors to hopefully keep it from starting again. Came inside and replaced the battery in the fob. Went back outside and started the engine with the fob in the ignition. I let it run for 3 or 4 minutes, shut it off locked door manually and left it alone for 10 minutes. Went back outside, unlocked doors and then when I locked doors back with fob the remote start started and the motor turned on. I placed fob in ignition and turned it off. Locked the car manually and am inside wondering what to do next???? Yes, it does have remote start on it....
