Tailgate

[Jess85]

 My tailgate keeps coming open when I get close to the truck and it has like 3 to 4 honks that go with it and it does it like 3 times before I can shut the tailgate.  It has come open while going down the road.

It's starting to honk more frequently and while running.

Have you taken it in for service yet?
