We just had our first hardware issue on our new Model 3. We took delivery of the car on Wednesday and the frunk latch worked flawlessly until Saturday morning. On Saturday morning I tried to show someone what the frunk looked like, but when I tried to open the frunk from either the iPhone app or the vehicle touchscreen it fails to open. You can hear the actuator making noise and the touchscreen indicates the frunk has opened, but the latch doesn't release so it seems like something mechanical rather than software or an electrical problem. If you reboot the main screen the frunk is no longer indicated as open and if you put the car in gear there is no error message so it seems like the sensor that detects if the funk is open is working properly. I saw someone report a similar issue on the Facebook model 3 group so I don't think this is an isolated issue.
I read through the user manual and there is a way to open the frunk if the 12v electrical system in the car fails (you remove the small round cover for the tow bolt in the front bumber and apply 12V accross the two wires under the cover). But this isn't supposed to work if the car still has a functional 12 v system. And it probably wouldn't help in this case since the issue seems mechanical rather than electrical. So I'd suggest not putting anything too vital in the Model 3 frunk until Tesla either comes up with a robust fix for the issue or describes an easy method to open the frunk latch when the normal method doesn't do the job.
