Maybe. There was a vulnerability [1] with BlueLink and that could have been an attack vector, but the article mentions:

> The attack can’t be done at scale, because the local network that the vehicle owner is using would have to be infiltrated by the attacker.

Wikipedia says BlueLink uses Bluetooth [2]. So I'm not sure what connection is actually used, but if it's Bluetooth/local wifi and there are no further security bugs, then it would be unlikely that someone else could connect to the car in the first place.

I can't speak on older BlueLink cars (article is from 2017), but my 2021 Elantra has GSM built-in and the commands are sent/received through the web - no bluetooth at all.

That sucks. Do you know if there is an option to limit it to wifi?

I've gone through every configuration menu the cars has and I've personally never seen the option to modify that.

Makes sense. I thought it was done over the internet when U saw login().
