Not super on topic for this thread, but since you asked. There were a few issues.
1. Traffic Jam Assist: In November 2020 production switched to cars with a newer version of the assistance systems that displays an icon when Traffic Jam Assist (an existing system) is active. Clearly the software was incomplete, because my Traffic Jam Assist didn't work at all. Sometimes I'd see the icon for a few seconds before it disengages. This meant that I never got any lane guidance from the car below 40mph when in traffic (only when not following a car). In traffic, the car did this lane guidance flickering instead:
. Audi Bellevue was completely useless and had told me a variety of these excuses multiple times: "the car correctly comes to a stop in slow traffic", "lane departure warning is not functional under 40mph" "lane guidance is a very sensitive system" "you should try some different roads" "we can't compare this system to that in any other Audi as the e-tron is a very different vehicle". Only the third time I brought the car in for service (for yet another issue) I insisted to have the service foreman join me for a drive, and he immediately said "oh yeah that doesn't look right". They had the car for 30 days (while waiting for a part for another problem) and couldn't fix it, even though they replaced all assistance related hardware. Audi just screwed up the software and doesn't have a fix for cars that were built with the bad software.
2. Radio quality is atrocious: HD radio sounds super bad, FM radio sounds kinda bad and Android Auto has issues too. 2021 e-trons onward have a new infotainment system stack (MIB3) that has the same UI but is very different under the hood. It clearly has issues with audio processing, as HD radio just sounds atrocious (pops of static every few seconds, high volume sounds are distorted which makes everything but classical music sound terrible). Android Auto has the pops issue, just not as often.
3. Coolant valve issue: about 2000 miles in I got a drivetrain cooling system malfunction warning that went away the day after. Took it to Audi Bellevue, got told after a few days they couldn't see any issues and the error code was likely "just an air bubble in the coolant, it's a new car after all". 20 minutes into my drive when I picked up the car again the warning reappeared and this time was permanent. Waiting for the valve replacement part took 30 calendar days in the end.
4. Door window surround trim is loose: on a longer trip I noticed at highway speeds that there's some flapping thing near my wing mirror that I could see in the reflection. The gloss black window surround trim (metallic without black optics) came loose at the front. Pushing it back in is fine for a few days but it's impossible to fully get it in again. Haven't had this serviced since Audi agreed to repurchase before I noticed this.
5. Infotainment system issues (and not small ones):
- The car will forget your saved destinations / radio favourites about twice every week.
- Sometimes it'll just forget who you are entirely and you'll get to redo some of your MMI / navigation settings
- While driving it'll often update the navigation maps, and when it does the navigation system reloads and forgets all your planned charging stops
- You'll sometimes have the car shouting at you every 30 seconds that you won't have enough range to make it, even though you're less than a few miles away and will arrive with over 25% charge.
- After getting out of the car, when you get back in the car will often have forgotten the names of your (charging) stops along the way and it just shows coordinates.
- The route planner will sometimes happily send you via a Tesla destination charger for a scheduled 8 hour stop instead of making a 20 minute detour for a great Electrify America charger.
- Sending destinations to the car via your phone only works about half the time. The other half you'll see the destination pop up in your car on your next drive (be that an hour or a few days later).
- Sometimes the route navigation just doesn't appear in your Virtual Cockpit or on your HUD. Fully restarting the MMI and the car sometimes fixes that.
- Infotainment is generally just slow.
In total the car spent 45 days in service since I got it April 8th. The assistance issue (Traffic Jam Assist) is still not fixed. The radio quality issue is structural and affects every 2021 Audi with Bang & Olufsen sound system, Audi will never acknowledge it even though they now ask sales advisors to disable HD radio before handing over the cars (since it's not as obvious with FM radio). Only the coolant issue is fixed. 1/3 of everything I reported, with an atrocious service track record both from Audi of America and Audi Bellevue. And then just a huge range of software issues that, without actual OTA update capability I wasn't expecting to ever get fixed.
On top of that I had some really bad luck with someone keying the car in week 1 of owning it (no idea who or where, I don't park or drive like an asshole), and then a rock chip on the windshield in week 2. Each of which costs me a $500 deductible.
Nope. I'm done. It's a good thing the car is being repurchased because I regret not going for a Tesla in the first place.
