Suddenly hearing pedestrian warning when reversing on 2016 X

[MikeC]

I have a 2016 X that I’ve owned for seven years. Today, for the first time ever, when I put it in reverse, the pedestrian warning noise that newer Teslas make when reversing came on. I didn’t even know it had the speaker for it. Even weirder, now when I put it in drive, it makes a weird static noise while I drive.

I did just get it back from the body shop 9 days ago to repair front end damage and I’m realizing now as I write this that maybe the replacement part included the pedestrian warning speaker. But this didn’t happen at all until today and I’ve been driving it for 9 days.

It's only possible on 2018 and up. Mcu2.
But absolutely possible tesla could make a Saw Bobo and sending this sound to the little speaker behind the IC (if the 2016 have this speaker. I don't remember)

Reboot your MCU with the two-scroll-wheel method. Might need to do it a couple times. My 2016 X has also done this a couple times, without any obvious reasons other than a computer glitch. I have the MCU2 upgrade as well, and no external speaker for that alert sound to play through.

How this sounds look like? I did MCU upgrade on my car but never mention any warning sound outside of my car when it’s in reverse.

It's not on the outside. It's inside the dashboard.

It hasn't happened again - just that one time - but it sounded like the reverse warning spaceship sound coming from a really bad, staticky speaker located under the hood (or maybe behind the dashboard as @Kristoffer Helle mentioned).

I have had the MCU2 upgrade for about 6 months now.
