Just FYI we had one hood fly up event with a Tesla/EVoffer mark 4.0 frunk. No indications that the frunk was open so not really sure what the deal was. The struts eventually stopped closing and had alignment issues which caused the frunk to eat the wiper arms. Ended up sending it back. It was a cool product but not worth the risk IMHO. EVoffer was nice and tried sending me a new ECU which did not fix. They did offer to send new struts but at that point I just elected for a refund and went back to stock.
They recently sent out some email about the landing feature (it is interesting that while I had the mark 4.0 with landing check I don't believe the manual was updated to include the information about testing the landing check functionality, so this may have been my issue. It has since been added to their install manual):
Dear Customer,
Our Model Y Electric Frunk MARK 4 has a landing check feature. We found that a lot of our customers did not know about this feature and did not test it after install, which we mentioned in our installation video and manual. We strongly recommend you to do the test to make sure it works on your car.
Due to car variation, we found that the landing check might not work on some Model Y. For that case you will need to
update the firmware to F28. We changed the way to perform the landing check on firmware F28 for those who fail the landing check.
Please be reminded that the F28 software is only built for MARK 4.1 control units with hardware version v1500. The label can be found at the back of the control unit. If you cannot find the label or the label does not look the same, please contact Tech Support (
