When I power on the volt it does the standard two slower speed chimes, then after those two chimes it switches to a louder more rapid chime. This is a 2012 Volt and it sounds similar to the really annoying chime as if the driver door was open even tho all my doors are shut. There are no errors on the cluster at this time. This chiming continues while driving it but seems to go away after ~ 10-15 minutes but as soon as I shut off the car and turn it back on again it starts right back up with the chiming. I have tried re-shutting all the doors, tried opening and re-shutting the hatch, popped the fuel door open and took the cap off and put that back on and shut that. After trying all of that I went and reset the center console to factory defaults hoping maybe that would help, unfortunately the chiming did not stop. Does anyone have any idea's what could be wrong or what I should try?
