Car noises during software update

[andrewsjra]

Is it normal for your Tesla to make noises during a software update? I usually don’t hang out by my car when installing them but the recent update I did and one in the past I notified strange noises while the update was happening. It kind of sounds like the A/C fan when this happens. Can anyone confirm this is normal?

Yes, it is normal. The firmware includes code for various controllers around the car. When they get their code, they usually reboot. So, relays will switch, motors will start/stop, lights may flash, etc.

Thank you for confirming. Couldn’t really find any threads about this but that definitely makes sense.

I have updated software several times, but it used to be at night while the car was in the Garage. For the first time, I was around in the Garage when the update was underway. I heard all kinds of sounds, including some kind of small motors whirring and lights going on and off. Was worried at first, and quickly searched this forum. So, I guess its normal and nothing to worry about.

Unless the car makes a break for it, there's nothing to worry about.
