    Hey,

    I made a quick video giving a demo of how you can open the frunk on a Model 3 if the 12V battery goes dead:

    I thought that wasn't supposed to work if the car's 12v battery is still working?

    I heard that going around, too. Not sure where it originated.

    My 12V is working and this still opens the frunk. I'd imagine this is a safety feature.

    I think that was based on an interpretation of a statement in the owner's manual. It appears that, rather than having this technique work ONLY when the 12v is dead, they only meant to say that this technique can be used when the 12v is dead (i.e., there's nothing preventing it from also working when the battery is still good). So, as with the S and X, the frunk is not a secure storage space on the Model 3 either.

    Correct. The purpose of the video is to both demo the process of where to press (since it's fragile) as well as remind people that the frunk shouldn't be considered 100% secure for valuables. (Quite honestly, nowhere in the vehicle should be considered 100% secure, but if people thought the frunk couldn't be opened, they might get a false sense of security.)

    Thanks for that video. Do you think 9V battery would do the same? Or not enough juice?

    I was wondering that myself because you could make a little waterproof case and place it somewhere outside the car.

    I was pointed to the Emergency Response Guide where I see, on page 28:

    "NOTE: The following steps will not open the front trunk if Model 3 has 12 volt power enabled."

    Either the manual is wrong or the ability to open the frunk while 12V is active is not the expected result. Because of this, I've reported the behavior to Tesla.

    I've seen a couple claims that it was easy to accidentally break the access cover for that. What did you think looking at it and interacting with it? Maybe someone was attempting to open pushing in the wrong spot, or do those clips look kinda fragile?

    Thanks for the video! I've read the thread about this, it was useful to see the demo.

    My impression is that, if you push in the top-right and then pull away gently and outward knowing the two tabs are in the bottom left, you shouldn’t have a problem. If you push then pivot, like a door, I can see the two plastic tabs snapping.

    I agree this is a security risk that could be prevented if the technique worked as stated in the manual (only in event of 12V failure). Maybe for safety reasons they have allowed the technique to work when the 12V is still active? For example, in a crash that disables the touchscreen (or it is inaccessible), first responders would need to get into the frunk to cut the first responder loop cable that
    shuts down the high voltage system outside of the high voltage battery and disables the SRS and airbag components.

    Page 28 of the first responders guide mentions the same procedure for opening the frunk (including the apparently false statement that:
    "The following steps will not open the front trunk if Model 3 has 12 volt power enabled."
    https://www.tesla.com/sites/default/files/downloads/2017_Model_3_Emergency_Response_Guide_en.pdf

    Of course a hydraulic tool could easily force open the frunk if needed and there is a secondary rear pillar first responder cut loop also if the one in the frunk is inaccessible. Regardless, Tesla should probably correct the manual to reflect what the OP has seen or revert to the process as stated in the manual.

    Thanks for the video and for reporting this discrepancy to Tesla. This may be similar to another report where it was discovered that valet mode did not prevent the glovebox from being opened. Either the behavior needs to be corrected to match the documentation or vice versa.

    It is still safer than the S and X...but did anyone receive a reply from Tesla?

    I wanted to update that I filmed this again to make sure this result didn't happen because my phone was in range (despite being inside on the other side of the home). I also tested that the doors were locked and the charging cable would not release. In the same shot, I'm then able to repeat the process and the frunk opens. I then go back and verify the door is still locked and the charging cable won't release.

    That's my goal here. Both to inform owners (and future owners) and provide Tesla with information they can use to clarify or correct. I obviously can't speak for Tesla as to the functionality they are looking for here.

    @MarkS22 thanks for reporting it. Can anyone else test this to see if it's a general problem?
    The manual says that it should only work when the 12v is not enabled, which would make the frunk more secure than the X and the S. If that is not the case then it's even less secure since the alarm did not sound.
