They have to replace the entire head unit to update the software? What should be a 10 minute fox will become a multi-day ordeal.
I just came back form picking up my Stinger from the dealer after they performed the PS573 (this is the official pit stop bulletin released by KIA to address the issue), which involves a head unit replacement to fix the issue with the fader moving to rear speakers randomly. No software update for the infotainment system without replacing the whole head unit.
I would also like to thank my service adviser, Sebastian Flores, who was very accommodating during this process, he even took some photos of the install so I can post it here for you guys. Also thanks to Rick Hall (sales manager at Westside Kia) for making the process a breeze and providing a loaner vehicle (Sorento).
The head unit replacement takes a few hours perform, so you will definitely need to drop it off and pick it up later that day or the following one.
Here you can see the that the replacement unit is a brand new unit and not a refurbished one. It also came with an updated navigation map sd card

Here you can see that almost the whole front of the dash has to be removed in order to gain access to the head unit.
On these next two photos you can see the new head unit being installed
A bonus that I was not expecting is that the new head unit came with an updated Nav map SD card.
NOTE: I had not updated my NAV via the courtesy update offered by Kia. I had the version that came with the car when I first bought it.

Man it sucks that they had to do that much disassembly to fix it.
They may have significantly increased your chance of experiencing some creaks and rattles.
What kind of audio system isn't flash updatable for these sorts of things? And assuming there is in fact some good KIA-specific reason for that, proper testing should have picked-up the problem before committing to thousands of these defective units. It was discovered in the wild immediately.
@Marc Collins I would hardly call it incompetence. As @tofu mentioned coding software is no easy task. There are hundreds of thousands of line of code written into the infotainment interface and issues like these are hardly identified when compiling the code, as the scenario under this issues happens is very specific. This can happen to any manufacturer and I am sure it has, maybe not this specific issue, but something software related.
I am glad Kia reacted in time and found a solution for all those affect by the problem.
