In June 2020, I started getting a strange error that would pop up randomly from time to time: USB Device Malfunction. UI_a112
Honestly, the error was livable, the USB ports would reset right away, but I would have interrupted USB recordings. The major issue was the error beep from the car making me think a braking emergency was about to happen and scare the crap out of me. This could happen randomly at any time.
In fact, it was so random that I could be in camp mode, sleeping in my car and it would happen at 3am and wake me up, startled.
During this year, I had brought my Tesla 3 into service on 6 different visits. Each visit, they would keep my car for a week and give me a rental. EVERY time, they would first blame it on the USB card I was using (which is the same USB card everyone here suggests, a Samsung class 10 128GB card). Then, Tesla would blame it on the fact that I was using a 3rd party charger for my phone. Because of this, after the first time they told me this, I disconnected this device and never plugged it in again. Still, the errors would persist. They changed the USB hub, and I would continually change the USB cards.
The many service visits were annoying. This error was so random, I don't blame Tesla for that, because it would sometimes take 48 hours in between showing up. But the error started getting more and more frequent, by the end happening 3 times per drive. All of these errors would show up in Tesla's notification logs.
Solutions included switching to a Tesla branded USB, throwing away the third party charger (even though it was never plugged in), resetting the Tesla to factory settings, not plugging in a USB (not an option for me with all the crazy drivers on the road), dealing with it, blaming the Tesla call center (this actually happened), and unknowing glances as if I was an annoying customer. Of course, none worked.
Finally, I got to the rare service center employee that actually listened to me. I told him that in early June 2020, I had my hardware upgraded to version 3, and that's when the USB issues started. In fact, the person who installed the HW 3 connected the rear camera wiring so that it bent a pin and wasn't showing up every time I put the car in reverse. So I wouldn't doubt if something else was wrong with the install.
At wits end, and another week in the service center, the service manager finally agreed to replace my T3 computer. It worked- I've had my Tesla for a full month now and not once have received the dreaded error.
I write this to let anyone else who has had this frustrating error come up that I did get a solution to the problem, and hope you do as well.
