I have a 2017 tundra crewmax…
I have a 2017 tundra crewmax that did the same thing it’s called the (hood bulge) this is a well known problem with the tundra! I personally took mine off & reinforced all the clip mounts with JB weld & then used new factory clips with a little felt tape over the clips for a tighter fit. Pop it back in, tighten the 10 mill nuts & it has never popped back off yet! We will see. Hope this helps.
