Strange noise on 2024 GX 550

[89yoda]

Hello! Recently had our 2024 GX 550 with 23k miles start making this very loud ticking/knocking noise on start up. Does anyone else's do this? It seems to stop after about 20 seconds. Hasn't done this for the first 2 years of ownership. No codes or lights for now. Dealership has seen the video and tried to play it off as high pressure fuel pump but there's no way it should be this loud and just starting. We aren't part of the engine recall that I know of yet. Just curious if anyone else has ran into this.

Yikes! My 24 doesn’t have that at all . I’ll double check when I start again from cold.

Does not sound good at all. Get that thing to the dealer.

Scary. Document everything. It sounds like a fan hitting on something?

My 2024 doesn't make that sound either. Don't let the dealer BS you.

Not sure what its supposed to sound like. Found this on a quick Google search

I would take your vehicle to another Lexus dealership and have the service manager get involved for a credible explanation and solution. Good luck.
