We have an electric tailgate on the Alltrack and last night I pressed the button to shut it when I noticed that something was in the way so I manually held the tailgate to stop its travel ( as the handbook says you can ).
I have done this many times before incidentally.
There was a loud crack like a rifle shot which emanated from the two bolts holding the tailgate to the raising and lowering mechanism which had both sheared off leaving part of the thread in the hinge on both sides..
Booked into the dealers for a looking at in three weeks time ( my choice ) so we shall see what they say.
It still works but I have to close it manually,first world problem I suppose.
