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?

Wild guess not listed in your guesses:

Maybe is sees a phantom passenger- try bucking all the seatbelts.

That also would be my first guess. When I first got my 2011 I would get random chimes. After a week or so I figured out something as small as a cell phone on the passenger seat if placed in a certain spot would set off the seat belt chime. So maybe you have something on the seat or the sensor is bad. Like RePo said, try buckling the seat belt and see if it goes away.

I have a theory, because this happened to me too a few times.

I think if your phone has the wireless charging coils built in it can confuse the seat sensors if the phone is in just the right 8 or 9 inch circle. I tested this with my Galaxy S7 (wireless charging built in) and my wifes iPhone (no wireless charging) and got inconsistent results with the galaxy and never a response with the iPhone.

of course this is a sample of exactly 1 and I never -consistently- repeated results.

Most of the various chimes are accompanied by some kind of indicator display, message or light. These might be 1) on the DIC, 2) on the center console screen or 3) on the overhead console. Look carefully in all these areas for and indication.

One thing that will nag you with constant beeping is an unlatched rear hatch (or if it is latched, but the latch's signal is not being sent). But that has a clear indicator on the DIC, so you would know the cause.

BEEPS

  • High-toned beeps from the front speakers are for objects detected near the front bumper. (Ultrasonic Parking Assist)
  • Low-toned beeps from the rear speakers are for objects detected near the rear bumper. (Ultrasonic Parking Assist)
  • Beep with voice prompt. Navigation System Voice Recognition System
  • Several Beeps. Forward Collision Alert (FCA) System tailgating alert. Your vehicle is approaching another vehicle too rapidly, the red FCA display will flash. 2013 MY.
  • Three Beeps. Lane Departure Warning (LDW). The vehicle crossed a detected lane marking, the LDW
    indicator will flash. The Owners Manual may have a typo, also see Three Chimes. 2013 MY.
  • Four Beeps. There is insufficient time to fully charge by departure time.
CHIMING (aka BONGING)
Chime volume can be changed. Owners Manual: Instruments and Controls > Vehicle Personalization > Comfort and Convenience > Chime Volume. Not sure which of the chimes this will affect.

  • Chime. Delayed Locking. If delayed locking is enabled, a door or hatch is open when the doors are locked with the power door lock switch
  • Chime. Electric Parking Brake. The EPB is applied while the vehicle is in motion. The DIC message RELEASE PARKING BRAKE will be displayed.
  • Chime. Electric Parking Brake. Attempting to release the EPB without the brake pedal applied. The DIC message STEP ON BRAKE TO RELEASE PARK BRAKE will be displayed.
  • Chime. General Navigation Commands. The system responds to commands when feedback is OFF.
  • Three Chimes. Lane Departure Warning (LDW). The vehicle crosses a detected lane marking without using the turn signal. The LDW indicator will change to amber, flash.
  • Four Chimes. Driving and Operating. Entering the car, the key fob is in the car.
  • Five Chimes. Driver or Passenger Safety Belt. 1) The driver or a passenger is unbuckled, or 2) an object is on the seat such as a briefcase, handbag, grocery bag, laptop, iPad, cell phone, or other electronic device, etc.
  • Continuous Chiming. Driving and Operating. The driver door is opened while the vehicle is in ON/RUN.
  • Continuous Chiming. ENGINE OVERHEATED —TURN VEHICLE OFF. The engine cooling system reached unsafe temperatures for operation.
CHIRPING

  • One Horn Chirp. Charging has begun.
  • One Horn Chirp. Tire Pressure Monitoring System Relearn procedure. Confirms that the sensor identification code has been matched to this tire and wheel position.
  • Two Horn Chirps. Charging is delayed, scheduled to begin later.
  • Three Horn Chirps. Setting Panic Alarm. The exterior lamps flash and the horn chirps three times.
  • Three Rapid Horn Chirps. The RKE transmitter(key fob) was left in the vehicle. This feature can be turned off. Owners Manual: Instruments and Controls > Vehicle Personalization > Remote Locking, Unlocking, Starting > Remote Left in Vehicle Reminder. Car: Config > Vehicle > Remote Locking, Unlocking, Starting > Remote Left in Vehicle Reminder [uncheck]
  • Four Horn Chirps. Insufficient time to fully charge by departure time
  • Repeated Horn Chirps. Electricity was interrupted before charging was complete.
HORN HONKING

  • Soft‐note Horn. The Pedestrian Friendly Alert.
  • One Horn. Remote Lock Feedback. User configurable setting.
  • Horn. Panic Alarm pressed and held for three seconds. The horn sounds and the turn signals flash for 30 seconds.
  • Two Rapid Honks. Key left in car.
  • Three Rapid Honks. "Your car is still on!" Driver exited the car with the key and closed the door while the car is still on. 2014 and later, and those 2011-2013 that opted for the "Unintended Car Running" recall software update.
  • Two Horns. Tire Pressure Monitoring System Relearn procedure. The receiver is in relearn mode, or indicates the sensor identification code has been matched to the driver side rear tire, and the TPMS sensor matching process is no longer active.
  • 30 Second Horn. Anti-theft Alarm System. An attempt was made to open the doors, hatch, or hood while the alarm system was armed.
  • Continuous Horn. Charge cord unplugged alarm. The car is locked and the charge cord plugged in. Unlock door before unplugging. To disable the "unplugged" alarm on a 2011 you must take it to the dealer. Or, lock the door with the medal key and it's disabled for that lock/charge session. (Unknown if the key method also disables the horn chirping for power loss during a charge.)
GURGLING, WHIRRING, WHOOSHING

  • Front of car. The car is heating/cooling the battery coolant and circulating it. This can happen plugged in or not.
  • Rear of car. Can sound like a piston. The gas tank pressurization system may be engaged to pressurizing the gas tank.
CLICKING

  • Rapid clicking, drivers side rear. Heard when approaching the Volt with the key fob. (2012 +)

SILENCE

  • Car is on. Or off. Check the Blue power button if unsure. Enjoy. :)

Well I have checked there are no displayed messages, on the central display, the display by the rear-view mirror, or mileage\selector display. I have tried opening and re-shutting all the doors, I buckled all of the seat belts chime is still ringing.

I have to think its one of these:

Continuous Chiming. Driving and Operating. The driver door is opened while the vehicle is in ON/RUN.
Continuous Chiming. ENGINE OVERHEATED —TURN VEHICLE OFF. The engine cooling system reached unsafe temperatures for operation.

However I haven't even driven the vehicle and its chiming, so it makes me think maybe the sensor is bad for the driver door, anyone know where that might be?

Phones even without those coils can set it off. My old Nexus 4 set it off at least once. As did a foil-lined pizza envelope (like the delivery drivers have -- I just prefer to pick up my own in the way home).

well I read about people disconnecting the 12v battery to fix weird issues, that seems to have fixed my chiming issue as well. We shall see if it remains fixed over the next few days.

Good news it still seems to be working properly this morning, no constant chimes since I did the battery disconnect\hard restart. Has anyone added a quick disconnect to their 12v battery on their volt so its not such process to disconnect\re-connect the battery? I had to remove the rear cover to get into the battery compartment and my socket I was using (believe it was a 11 mm) was bottoming out on the top of the threaded screws.

Not that I recall. This is not something you do all the time. In 6-1/2 years, I have never needed to do it for a reset.
