Yes, it was extremely frustrating that the mechanical pull wouldn’t release the latch. That’s the very reason it exists. I tested it out when I installed it and it worked fine, but failed when I needed it most. Hansshow had no suggestions.I have the power frunk kit and it's been working fine for me. I did have an issue at one point and their support was not bad and got it resolved. I guess it's just luck sometimes.
Regarding the frunk being stuck closed, their kit comes with an emergency latch pull string which mechanically opens the hanshow portion so its weird that didn't work for you.
Don't defenestrate the frunk kit! Hansshow support is awful, but the frunk kit is fairly bulletproof. Not like the trunk kit where they want you to fish wires through a bent rubber sleeve and NOT damage any of the 24awg wires already in that sleeve. Good luck! At least the replacement Tesla trunk harness is only $70.Here to say I've had a similar issue with the Hansshow Trunk kit.
tl;dr Unless you are prepared to do all the installation yourself and then be Hansshow's unpaid labor to troubleshoot their failed product for them, run away.
I bought the frunk and trunk kit with toe kick combo at a Black Friday sale in 2019. Installed the frunk kit myself in a few hours. It was pretty straightforward, and it still works fine. However, I got a little intimidated with the trunk kit so took it to a local professional in Jan/Feb 2020. Worked fine for about 8 months.
Trunk kit stopped working in October. Contacted Hansshow, they said they needed more information about what precisely wasn't working. (I mean, it's supposed to open and close the trunk. It will close the trunk, but not open it. Sorry I can't be more specific than that.) So I took it back to the installer who fiddled with it and sent me both a video and a written description of what's mechanically misfiring. Despite all that, Hansshow customer service refused to even discuss the issue. They just said I HAD to do live troubleshooting via Whatsapp with one of their engineers. Well, I'm in no position to do it, and my installer already donated their time to thoroughly document the problem and wasn't really inclined to chase it further. So after weeks of going back and forth with Hansshow, I just asked the installer to disconnect the power and put the OEM latch back on so it would at least open and close. (It was going to be way more labor (i.e. $$) to take the whole thing back out than just to disconnect it.) As he went to disconnect power, apparently the close mechanism triggered, and as it was pulling the trunk closed, one of the lift struts popped off the hinge and shattered my rear windshield And of course by this point, we were in early pandemic and I couldn't get an appointment to the windshield replaced for, like, a month.
So, a year + later, I'm out over $2000 dollars (for the trunk kit with toe kick, original installation cost, and replacement windshield), and all I have to show for it is a trunk that exceptionally difficult to close.
Given the feedback on this thread, I'm inclined to take out the working frunk kit, the FUBAR trunk kit, and replace both with TOs, but I'm still feeling snakebit.
