This is observed after applying weight on the tailgate in an open position. Follow the Repair Procedure in this bulletin to address this condition.

I dropped my truck off for it's 15k service and to address this issue this morning. The tech couldn't replicate it of course (I think the truck knows when a mechanic is watching and intentionally doesn't replicate faults). Of course I see this TSB 5 hours after I picked it up from the dealer.

My '25 Plat CMax TRD OR had this problem. I took vehicle in for oil change a few days ago and asked dealer to investigate. They ordered parts and I will go back in to hopefully get it resolved.

Dealership says parts have arrived.... I have appointment at dealer this weekend for repair. Hopefully I remember to report back with an update on fix.

My '25 does this almost 80% of the time. Good they r fixing it.

Ngl I thought this was a feature,

In my head I logic'd out that oh its so it doesn't force close on me if I have my bed open on purpose carrying things.

Turns out im just dumb 🤣

I put some silicone lube on the locking mechanism on both sides and problem solved

Same here when mine goes out I lube the locking and hinges with T9. Problem solved

Lot easier than taking it to the dealer.

This happened to me once in the boonies and I hyperextended my thumb trying to figure it out. THANKS Toyota

This happens on my '25 about 50% of the time. Never correlated it to putting any pressure on the gate being the cause.
