Bought a 1-owner 2019 Model 3 Performance 6 months ago and its been absolutely perfect, love the damn thing. All I've done in my ownership is two things:
I guess I'm partly sharing the info in case it benefits someone looking this up in future. But also if anyone might have exprerience with this, something similar, or even any advice, I'd hugely appreciate it.
- Replaced low voltage battery (by Tesla mobile tech). Preventative measure, car wasn't complaining (it was just getting to 4 years old).
- Lubed splines on all wheels to eliminate clicking noise under acceleration/deceleration (by Tesla svc center). All noises ceased after this.
- Nothing remarkable in the last drive, went over the dashcam+sentry footage and nothing remarkable.
- I'd configured my phone as a key. I opened the boot/trunk, loaded it, and got in via the drivers door. All of this worked fine. Issue was only noticed when the screen stayed black.
- Multiple reset attempts (scroll wheel hold) and no result for the next couple hours. Tesla support recommended the same, nothing worked. Held for over 60 seconds a few times.
- Tesla support reported the car was offline to them. "Last seen" time on my app was about the time I parked it earlier.
- Unplugged all USB devices, retried steps above. Nothing.
- Let it go into deep sleep. Attempted troubleshooting about 6 hours later. 60 second double scroll wheel press, and I heard the vent flaps move. A couple minutes later it performed a total of 3 boot loops (showing the Tesla logo, then going back to black) and then the display came to life as normal.
- I immediately unpaired my phone, disabled PIN-to-drive. I now have access to driving the vehicle at least via keycard.
- Spotted code "UI_a161 Emergency call temporarily unavailable". Only one in the log.
- I've been driving it some today, and the screen stability seemed to get worse. Where it was on while parked yesterday, it frequently cut out on my drive and came back on. Towards the end it just stayed off. I occassionally had indicator/signal noises that would cut out. No consistent pattern. Its possible that when I used a signal and heard the "clicking", that when I turned past the cancel threshold thats when the noise stopped.
- Currently on v11.1 (2023.44.30.9 eef969740612). Installed a couple weeks ago I think. Its the only time after installing an update, that I didn't perform a scroll wheel reset.
- Since this update I've noticed that the car increasingly didn't notice the phone as a proximity key, and I had to take the phone out to unlock the car. Sure, this happened infrequently in the last 6 months but it went from something that happened 1x a month or less, to 5 times in a couple weeks.
I guess I'm partly sharing the info in case it benefits someone looking this up in future. But also if anyone might have exprerience with this, something similar, or even any advice, I'd hugely appreciate it.
