I would like everyone to know that if you have a brand new Kia, the process is even easier. I spent $20 on the Kia service manual access (didn't even know that was a thing until I read OP's post) it finally figured it out.
Modern Kias with the CCNC cockpit have a data connectivity unit that exclusively handles cellular. If you can get this unit unplugged, which only requires two Phillips head screws to remove, your set. It took me nearly 2 years to figure this out. Thanks OP
If you are considering purchasing a Kia, insist on getting a loaner or a 24 hour test drive.
The active driver assistance features are criminally dangerous.
Sadly, the current administration is more interested in illegally locking Kia’s engineers in cages than actually enforcing consumer protection or safety regulations.
Anyway, avoid them and Hyundai. If you don’t believe me, drive in rush hour for 30 minutes and frequently change lanes. Be sure to be on the road at dusk and dawn to get the full experience, where glare confuses the onboard cameras, so regen braking flaps on and off, and it repeatedly overrides steering and sets of spurious cabin alarms.
I’d suggest parking a few times at a costco during peak hours, but I don’t want to get anyone killed.
I hired a peugeot something (MPV) to drive in the french alps and it was insanely dangerous.
Driving mountainous switchbacks with very tight corners it was so strict about not wanting to cross the central line that it frequently tried to dump me into either the mountain or over the cliff.
Similarly on straight 2 lane roads where only really the centre was clear of snow and ice it was adamant that I should be driving with 2 wheels in deep snow instead of daring to drive in the middle.
Any clues on how to disable any telemetry on a Kia Stinger?
Yes!! I still have access to all their service manuals for the next 48 hours.
What's your year model and engine? I'll look it up.
