I've got the 2019 Prestige with the following issues
- Virtual cockpit resets to default very every few weeks
- Shortcut icons disappear
- MyAudi is constantly having connectivity issues to the car
- Customize the MMI home screen and it resets every couple of weeks
- Online map updates take days if not weeks to install
- Tons of random warning messages when nothing is actually wrong.
I've given up doing any customization on the MMI and not even bothering with the MyAudi app anymore. It's been weeks since I've been able to get the app to connect to the car. You raise these issues with Audi and the stock standard response is "this is the first we're hearing of this" when it's in numerous forums of people having issues. On top of that, the key fob is so sensitive that every now and then you'll come out to see your trunk open. The trunk will try and close on you whilst you're getting items out. When it's raining, forget about using the rear view camera as you can't see anything. The final nail in the coffin for me was when the car navigated me to an EA station in the middle of nowhere that it KNEW was completely offline. EA had pulled all the chargers out for maintenance \ replacement and the navigation system actually knows which EA stations are online and being used but the wonderful software programmers at Audi didn't think to tweak the algorithm that if all chargers are red either route somewhere else or flag a warning message. I had to drop my speed to under 50mph on the freeway to make it to the next charger.
I've given up complaining to Audi as they have no interest in fixing the issues and only selling new cars. I asked for a lease buyback and VW refused because "software" issues aren't a valid justification even though it's been with them numerous times to get the software re-flashed or if an update is available to have it applied.
