I would if they are the type of dents that can usually be fixed that way.

How bad is the hood flutter? I can only tell when going 55+

Well, they had my hood off for my 5k. Now I have dents in my PPF and even a little tweak in the hood. They ordered the parts and wanted to keep the vehicle until August!! Yeah, fuck that noise, not driving an rx instead of my baby for three months.
I also had them look at a rattle in The driver side door that I only heard when the music was turned up. Turns out when the dealership I bought it from Fife Tacoma Washington did the window tint. They broke a few of the door clips and never said a peep. I will be asking them to replace the ppf on the hood when they do the flutter TSB. Apparently the parts, whatever parts those are, are on back order. And my brakes won't be ready for the fix until late this year or early next year. Hopefully by then they have the software update baked and ready to load because my transmission is driving me crazy.

Took my GX in for miscellaneous fixes this past week (squeaky brakes, hood flutter, stereo comes on full blast on restart, transmission clunk, etc) they still have it. One of my issues was that my driver's side window makes a loud squeak going up and down. They called and said whoever did the tint on the front windows broke some parts in the door and the repair is $400. I bought it used with 5,000 miles on it. I am guessing like yours the original dealer did the tint.

As of today (April 19, 2025), there are 0 Recalls, 0 Investigations, 3 Complaints and 31 Manufacturer Communications. If you click the 31, you will see the communications that have been issued by Lexus. One of which is the Hood Flutter. You can download the Lexus Technical Service Information Bulletin, but frankly, by the time this has been issued you shouldn't be getting the dealer "could not duplicate customer concern, no repair done" response anymore.

If you see something, say something!

Those of us that jumped early because the GX looked so darn good have had an uphill battle to get things fixed on this first model year. Early on, it is hard to even get issues acknowledged, let alone fixed. I took a Lexus technician for a drive on the highway in January when I couldn't take it anymore, just to show him how bad the "flutter" really was. That hood did its exotic belly dance for him and he couldn't take his wide eyes off of her. The tech video taped it and acknowledged that it didn't seem right. My contention had been that it is a real safety issue because it was impossible not to stare at it when it's dancing.

Complaints roll into dealers. If there isn't a bulletin on the issue then it's likely to be given back to you with the dreaded "could not duplicate issue" response. The same issue has to pile up in front of the dealers for quite a will before the complaints capture the attention of Lexus corporate. The issue complaints have to pile up enough at corporate before the work begins to figure out what to do. When Lexus finds a solution, they issue a bulletin.

My 2024 GX 550 OT + was repaired in mid January of 2025. The bulletin was issued February 7, 2025. I know there are others that had the hood flutter repaired before mine and I am thankful for things like this forum that facilitate owner discussions. The forum helped me realized that I was not crazy and I was not alone. The system is designed to drown the voice of individual complainers. If something is really not right, then we must use our collective voice to make change.

My 25 GX hood is simply too light of gauge steel. It flutters.

You honestly think there's a significant number of people who can't see their hood when they're driving?

Funny you say that - I sit with my seat at the lowest position and can't see the hood flutter when I'm driving, so it doesn't bug me. I honestly forgot it was a common problem until I purposely sat up to look for it.

I'm sure it would bug me if it reflected sunlight at just the right angle into my eyes, but it doesn't seem too bad at normal highway speeds.

My 25 GX hood is simply too light of gauge steel. It flutters.

I believe it's aluminum, but I've had several cars with aluminum hoods that didn't flutter at all. I think the structural supports under the upper hood bodywork are simply poorly designed or manufactured, combined with poor aerodynamics.

You would be astounded how much air gets trapped in the engine bay of cars that don't have underbody aero covers - easily enough to generate lift and alter handling at 80mph. Our racecar miata was noticeably floaty at 90mph before we put the factory undertray on.

Sorry to bump an old thread but Lexus gave me a TX350 as a loaner while my GX is in for service and the hood flutters SOO BAD. WAY worse than the GX550
