Whenever I drive in a 'serious' manner e.g. mountain roads, after a while (say 30 minutes) the liftgate (hatch) starts to emit a metallic rattle over small bumps. It sounds like the latch has partially released. However when I stop, the liftgate is firmly closed as usual, and opens as usual. Opening and closing the liftgate cures the problem until the next similar drive.

So far I've tried some dry waxy lube on the latch - didn't work. I guess the car is flexing enough to partially open the latch - does that seem feasible? Any suggestions for a cure? I could not see any procedure for adjusting the liftgate latch in the workshop manual. Does the latch have some way to adjust it? Thanks for any advice. :)

BTW this is not the infamous "loose bolt from the rear wing" issue - if that was the case I'd hear a noise from the bolt when opening the liftgate - and there is none.

Searching, I came across this old thread - and wondered if some electrical gremlin is triggering the internal release so that the liftgate is partially opening. This should not occur when the car is moving and definitely not in an AUS delivered RS which does not have an internal liftgate release button!

Just confirming FYI that the liftgate latch does have adjustment and was the cause of my rattle. Two T40 bolts hold the latch mech and can be accessed without removing the liftgate scuff plate trim panel, because Ford kindly put two small covers in that panel. I removed the covers by pushing them out from the inside with an angled trim tool. There is a lot of adjustability horizontally and some vertically.

I carefully moved the latch mechanism vertically down just 1mm i.e. 'tighter', and applied a film of clear silicone grease to the contact points. This cured the liftgate rattle. :)

My car does this in cold weather over bumps. But only in sub 30°F weather. Soon as the interior of the car warms up, it goes away.

Hard to pinpoint the noise as I'm driving, but maybe if I had someone in the back who could pinpoint where on the hatch it comes from it would help.

I also have a loose spoiler nut like some others causing rattle. Tis annoying.

When I take it in for a service I'll have them fix all the annoying things. I'd have them fix the seat shimmy issue, but their fix would suck more than me following the same fix with swaybar mounts that others have used. I often thought about using the mounts, and drilling a small hole and threading it. Then using a set screw to ensure the seat never, ever shifts again.

They all do. A lady friend of mine suffered a similar thing with her Subaru and asked for it to be fixed at two consecutive services only to be told it didn't do it for us. My mate got sick of her being fobbed off and adjusted the serrated plate a little tighter and same as you problem solved. Took all of 5 minutes on the Subie. Why wouldn't you as a dealership mechanic just spend the 5 min whether or not it did it on your test drive? The mind boggles.
On the subject of silliness my DD Kuga had a failed tail shaft centre bearing after 80,000 klms. No worries, a $50 bearing that cant be replaced unless you take it to a tail shaft specialist and spend $400 or a complete new tailshaft from Ford for $1700 plus $300 fitment. A $2000 bill for a $50 tailshaft bearing that only lasts 80,000 easy klms. My next DD won't be a Ford thats for sure.
