While some of the chirps are useful, the horn honks are really annoying. I've read through my user manual and this forum. Perhaps something was missed and someone here can point me in the right direction.

1. Triple honk. This is really annoying, especially when leaving early in the morning or coming home late at night. I have this option disabled, and reconfirmed it, but my car will sometimes triple honk when my car is off and key fob is in the car. It doesn't even allow me 2 seconds to exit the car. Other times it doesn't seem to honk. To me, the way it works is not consistent and seems like a really stupid option. I always lock my car with the key fob so for me, this option isn't even needed. But, if disabling it through the center stack worked as intended, this would be a moot point.

2. The chime volume. Even lowering it to the lowest volume, I can still hear it on my neighbors porch. I was installing tint on my car yesterday and was really annoyed with the chiming. It's worse than a smoke alarm with a low battery. Does the chime use the car speakers or is it a separate device? If separate, the wires will be cut.

3. Interruption in charging. I'm not talking about removing the J1772 plug, just the power. Sometimes I need to use the 120V outlet for other things and when I remove the plug for the charger, the car chirps for ~2 minutes.

4. Charging based location. It doesn't work. I've updated my home location a few times and set it to 12 amps but it always reverts back to 8 amps.

5. On Start notifications. Charge full texts don't work all of the time and the car is being charged in the same spot every time. Not a big deal, just curious if this is normal.

Other than that how do you like the car?

1. The triple honk is there as an idiot proof measure. Annoying, but effective. Stop the car or don't close the door and the problem is solved.
2. When installing the tint, shut down the car. No problems what so ever with the chime then.
3. Use the key to stop the alarm when you interupt the charge.
4. Is the GPS engaged and working when you enter your location ?
5. OnStar notifications are not the most reliable source.

P.S. Enjoy your new car !

3. Are you removing the plug from the wall while it's charging? If so, please don't do this. Stop the charge from the J-plug first so you're not yanking a plug with 1.4kW going through it. The risk may be low, but it defeats some of the safety of the J1772 design to unplug from that end.

On gen1, you can disable the "power disconnected" alarm in the vehicle settings. Is that no longer the case? It had 2 separate alarms... one for charge cord theft, and one for power disconnection. I disable both on my gen1.

Not true.....at least with my car. I don't even have a chance to exit the car and it does the triple honk (sometimes). It's only supposed to do it after closing the car door? If so, mine isn't working correctly.

Are you really sure about this, because it is not normal. The car should "honk" only when you closed the door with the engine on. Or if you left the key inside the car.

I know it's not normal. That's why the question was posted.

I can tell you 100% that sometimes the horn will honk 3 times without closing the door. In fact, I think it happened once without even opening the door. Additionally, this function is disabled in the center stack.

The tripple honk cannot be disabled from the center console. What can be happening is, sometimes the console lose the communication with the keyfob and that may leed to a honk and usually a message in the dash. When you experienced this, did you saw any messages in the dash pannel ? Usually they are there.

#1 - A case where my 2016 triple-honks is when my wife hides her purse in the car with her key fob in it. After we are out of the car and the doors are closed, I then lock the doors with my key fob.

#2 - uses the cars speakers.

#3 - agree with others you should always disconnect the car side first. There is a menu option to control the honking though. ("Charge power loss alert".)

#4 - it works fine. Hopefully someone here can walk you through it. (Its been a year since I set mine. But then I quickly went to 240v charging where is doesn't matter anymore.)

Pro tip: before you use 12 amps, turn the circuit breaker off to the receptacle, unscrew the receptacle, and check to make sure the wires are clamped with the screws - not the back stabs. If it is a cheapo $0.39 residential grade receptacle, go over to your local big box store and buy a commercial ("spec") quality version.

#5 - works fine for me.

Yes it can. Page 146 of the user manual.

Don't recall any messages but I'll check again to see if there is any.

Ok, I searched the word "three" in the manual and apparently there's four cases in which the horn will honk three times. I kept thinking it was related to the key in the vehicle alert but the honking can occur due to any of these reasons.

1. Remote Left in Vehicle Alert - When the vehicle is turned off and an RKE transmitter is left in the vehicle, the horn will chirp three times after all doors are closed.

2. Remote No longer in Vehicle - If the vehicle is on, with a door open, and then all doors are closed, the vehicle will check for RKE
transmitter(s) inside. If an RKE transmitter is not detected, the DIC will display NO REMOTE DETECTED and the horn will chirp three times.

3. Lockout Protection - If the vehicle is off and locking is requested while a door is open, when all doors are closed the vehicle will check for RKE transmitters inside. If an RKE transmitter is detected and the number of RKE transmitters inside has not reduced, the driver door will unlock and the horn will chirp three times.

4. How to Detect a Tamper Condition - If (unlock icon) is pressed on the transmitter and the horn chirps and the lights flash three times, a previous alarm occurred while the system was armed.

Item one can be disabled but the rest cannot. Providing the center stack is working correctly, that leaves two through four as the possibilities. It doesn't seem like any of those fit what has been occurring but now I need to go back to the car and pay attention to the exact behavior. Using the same honking sequence for four different conditions isn't a good design IMO. In addition, the user should be allowed to select using the chirping device instead of the horn for these indications. It's less of an annoyance.

In the Gen 2 Prius, it has similar notifications but uses a low volume tone instead of the actual horn.

This happens to me occassionally. Maybe once in 50-100 uses. I have yet to definitively figure the combination of events that makes it occur, but I think this is how it goes. I have parked the car myself, power down the vehicle and open the door similtaneously as im getting out of car within a second of shutting down the vehicle (kind of like I'm in a rush), then i get a triple honk. When this happens, i simply turn the car on again and then turn it off and the problem is solved.

It seems to always happen to me when I'm a rush but haven't identified the definite issue that causes it. Not sure if this is your same situation, but this is what I remember when it happens to me. Hope this helps.

I find that to avoid the "leaving car running" triple honk, make sure you unlock your doors using the lock/unlock buttons on the door rather than pull on the door handle twice to manually disengage the lock. The lock/unlock buttons tell the Volt you want to leave on purpose so don't triple-honk. Only works if you leave a door open while you're outside the car.

I've confirmed one of the horn honk issues. Driving down the driveway, my sons bike was laying right in the middle of it. Stopped the car, put it in park, exited the vehicle and closed the door. In addition to the annoying ding, ding, ding, that was followed the more annoying triple honk.

There's nothing that can be done to disable that? If not, a mod will be installed that will only allow the horn relay to close when the drive selector is out of "P."

You can't disable that one...it's there to prevent you from accidentally leaving your car running while leaving the vehicle. After a while, no matter the charge of the battery, it will hit empty (especially if the climate control is on) at which point it'll start the engine, and you wouldn't want that happening in a garage, so they're very persistent in telling you that you left the vehicle running without being in it. It's also an anti-theft device...if you left it running and took the keys out, someone could drive it away, whereas if it were off, they wouldn't be able to start it.

I'm able to reproduce the triple horn honk issue.

After driving, I turn the car off and without opening a door, the triple horn honk occurs about 1-2 seconds afterwards. The way I was able to reproduce it was to put my key fob on the right rear side of the passenger seat.

This makes no sense to me and doesn't even fit any of the triple horn honk criteria.
