If you get yours done, be sure to check it!
Never had a single problem with my tailgate and then after the recall it would not stay closed.
I had to adjust the strikers back myself. Recall has them adjust it too tight, IMO, with no movement. You had to slam the thing with two hands to get it to stay. I think temperature fluctuations caused it to not align perfect. Only been a single trip since I adjusted it back myself but it was super annoying to have issues after the recall was done.
I'll tell them to mark mine done, it's always worked just fine, even after the wife smashed the top of it into the boat trailer winch.
They will also be instructed not to load any PCM updates to my truck. Next time it goes in it's for cab mounts and the Cummins chirp/squeal in the serpentine belt/pulleys.
