2024 GX550 Overtrail Right Rear C-Pillar Noise (1 Viewer)

[gx550 OT noise]

Hi everyone,
I own a 2024 GX550 Overtrail and since around 2,000 miles I’ve had a persistent rattling/creaking noise from the right rear C-pillar.

• Hot weather: noise gets extremely loud.
• Cooler weather: still there but weaker.
• 80–90°F: almost disappears, but always comes back.

Dealer visits so far:

• First visit: I test-drove with the tech, we both heard it, they tried a fix but it didn’t solve it.
• Later visits: noise didn’t appear during inspection, making it impossible to capture. When it’s quiet, the car feels perfect — but often the same night on my way home, the noise returns. This has become mentally exhausting, as I’m always listening for it.
• Recently I booked a same-day appointment via the Lexus app right after hearing the noise, but the dealer refused, saying same-day isn’t allowed. If so, why does the app even show that option? And what if the noise disappears by the time of a scheduled appointment?

At this point I’m frustrated. The issue is real but intermittent, and service advisors sometimes make me feel like I’m being unreasonable.
Questions:

1. Has anyone else had the same C-pillar noise on a GX550 or LC250?
2. Any NYC owners with this issue?
3. Can anyone recommend a good service center in NYC where I can bring the car in immediately when the noise happens, instead of waiting for an appointment?

Thanks for any advice

That would drive me insane. Wish I could help diagnose, wishing you the best.
