I can remotely summon the car with nobody inside.

I can engage autopilot and the car essentially drives itself.

I can remotely vent the windows..... heat the seats.....and control the interior temp....etc.


However I cant get a simple thing like my horn to work - after visiting my service center for 4 times.

I just made an appointment for the 5th time concerning the horn. Both the high tone and low tone are gone.


Anyone else experiencing this?

have they fixed it each time and than it breaks again? or are you leaving each time and it is not fixed? If its fixed each time, is it the same part each time? Schaumburg?

I have a similar thing, when the car sleeps outside and it is wet and cold, the low horn is not working, when it sleeps in the garage, all is ok. One time both horns didn’t work.
I think it is caused by a bad contact, in the wire harnas or the horns themselves. Since it is so intermittent I suspect a bad earth. I plan to take the frunk out and check the plugs and earth points.

I am sorry for your issue and hope you get it
fixed soon. Most of older cars, the horn did not work.
Since then I have either had slow cars so I never need a horn
or really fast cars that did not need a horn.

One of my horns went out twice, not sure which one, but it was the same one both times. Both times they were replaced under warranty by mobile service.

Every TESLA has 2 horns? I know my Sprinter only has the one horn.

I too am having issues with my horn. I take the Frunk apart pretty regular-like, doing installs and upgrades to the Frunk opener, so I assume it was something to do with me, but when I press the horn often the only response I get is the camera saving the footage to the USB stick. But when I next try it, all's well. I haven't figured out what the chain of causation is. Software updates?

I too am OOW so I will NOT be having Tesla look at this.

@Randy Spencer also OOW so have to check this myself. One of the 2 horns quits when it gets cold and wet, so my bet is on a bad contact.
Now I haven’t taken the frunk out yet, do you have some pics of the inside of the front? Where the horns supose to be?

Well I was going to say why don't you Google it but when I do that this is what I find:

The actual horn is at the very front under the front bumper. Sadly I didn't take pics or videos, but I did test a friend's Model 3 and his horn sounds different than mine. Gonna have to see if someone else can beep their horn at me so I can see if it's my car or his that is missing a horn. If it's me than an intermittent connection with the remaining horn would explain my intermittent horn issues.

I am glad to know now, thanks to this thread, that I can beep the horn with my right thumb easily. Always had to bench press the horn to get it to activate in the center.

There are 2 physical horns. My lower-tone horn was being flaky, and mobile service replaced it. A properly sounding horn should have 2 tones, about a major 3rd in interval.

When you lose one of the horns, it sounds like a clown car horn.
