“About 7-8 times now, the tailgate has opened under it's own power unexpectedly. It has happened while stationary after just starting the vehicle, while in reverse and in forward motion. All instances seem to happen shortly after the vehicle has been started.”

NHTSA complaint #11406455, filed 2021-04, 500 miles

“The contact owns a 2021 Ford F-350. The contact stated that while the vehicle was hauling a trailer with a tractor, the tailgate unintendedly opened, causing damage to the tailgate. The vehicle was taken to the dealer where it was diagnosed that since there was no water leaking under the front passenger's side floor mat, the contact needed to pay out-of-pocket for tailgate replacement. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 23,000.”

The contact became aware that water was dripping from the sunglasses compartment located on the ceiling above the rear-view mirror. The contact had not taken the vehicle to a local dealer or independent mechanic. …”
