Hello,

first time poster here.
hoping this community can help me figure out a recourse.

Initial inquiry with dealer was met with hood latch and bump stop adjustment.
Further attempts to bring this issue up resulted in “no fault found”.
I’m in discussion with Lexus customer engagement team and the selling dealership on a hood flutter problem.
I can see the hood start to vibrate at 50mph and onward, with it being really bad at 80mph.
Dealership went on ride along and saw the problem as described.
Dealership and customer engagement team both have determined this is normal design.

Asking owners here to see if you have noticed this flutter/flapping issue.

 

I experienced this also under the same conditions as you described. My remedy was to adjust the round disks in the engine bay that the hood sits on by twisting them to raise them so they fit snug when closing the hood. Took a couple of times to adjust but no more hood flutter.

 

I had this problem when I picked up my 2026 TX500h FSL and I saw some videos of the newer Lexus vehicles with dual latches under the hood. So on my way home from a trip, I couldn't take driver's side fluttering, so I remembered the video I watched and I pulled over and I opened the hood and made sure I closed the hood with equal pressure over both latches as I closed the hood and 2500 miles later, I don't have that flutter anymore. I hope this helps as an option to your flutter.

 

Yes, I've definitely noticed it at highway speeds, It's one of several things that have disappointed me with the the purchase of this $80k premium vehicle. I don't know how they can not correct so many obvious flaws before taking them to market. The thing that ticks me off the most is the fuel door that doesn't open and has to be pried open with a credit card. The absolutely knew that was a problem the day I purchased my TX and drove it home... but they waited for me to call them about it before they ordered the replacement door and inconvenienced me with driving it back to the dealership and waiting a half of a day for them to fix it. Lexus should be better than this.

 

Hmm. No flutter in the hood of my 2026 TX500h FSP. (3,200 miles). I suspect what other have commented on - that either the hood is not properly latched down on BOTH sides or the hood bump stops are not BOTH adjusted to be tight against the hood when closed, n your TX500h. Generally they are adjusted via a bolt at the base of each stop.

 

Normal design my ***. Pardon me, but that's an utterly ridiculous statement.
