NHTSA Complaint #11419221 — 2021 FORD F-250

The truck tailgate opened by itself 4 times since receiving the vehicle (5 month period). It happened both while stopped and while driving. This put drivers behind me at risk for cargo spilling out, though luckily that did not happen. The last incident scratched and dented the lift gate as it fell upon an attached bicycle rack in its raised storage position. I have not yet reported it to the dealer and plan to do so when I return from a trip. No messages on the dash were noticed. The problem appeared during the first month of use, but I assumed it must have not been fully closed. Since then I have been much more careful of closing and checking the liftgate, and I still find it open or hear a thud as it fully opens while parked or driving.
