I changed the frunk struts to my 2021 in 5 minutes and now it open on its own for only $15 struts...No need for the electronic ones for $300 plus.. yes i must close it manually but works great. (moderator note: removed link that was created using amazon affiliate program)
Why would it. The car has a built in safety to not allow the spring to release at all while in gear. New struts have no change in how the latch works.
I am tempted. I agree the chances of it opening in flight are pretty low.. if the latch is not latched it won’t stay closed...
I put new struts in for both the frunk and the trunk probably a year and a half ago. Never had an issue with them opening on their own.
Those were some cheap fun until my hood started to have outward dents from the force of the struts. The front lid is not made to handle that extra force. They went in the bin.
I have had those same struts since May 2019 with no issues. As far as the hood opening while driving, even with the standard struts, if you are travelling at any normal speed and the latch isn't secure, it will blow the hood open.
There was a huge thread a couple years ago about changing out the gas struts so that the frunk hood would "pop" open without help. I did it. Works fine, but for some, you may also have to change the spring that holds the latch shut, which allows a finger to close it. Unlike @tll, I haven't had any bending issues.
I installed ones from basenor. Have worked well. About 1 in 5 times it does not auto open but still a nice improvement for a low cost. Tesla Model 3 Front Lift Hood Supports (Set of Two) https://www.amazon.ca/dp/B07TBGGM6T/ref=cm_sw_r_cp_api_i_DSAC8JS8FF5TS2SPPPSC?_encoding=UTF8&psc=1
Closing the frunk is the annoying problem solved with the electronic ones. Opening it has always been easy.
Keep in mind that doing this to the trunk makes it impossible to close the trunk with one hand using the interior handle.
I added them to my trunk. Cost less than $20 and took less than twenty minutes. Definitely a little harder to close and it doesn’t open as wide, but still an improvement, particularly as cheap and easy as it was.
I was going to get one of these options. But after owning my M3 a while I just don’t go into Frunk often enough to justify small expense, or risk of warping the trunk. I keep charge cables, first aid, tire puncture kit, etc tools. I personally hope I never open my Frunk.
