Hey everyone,

I have a 2022 Tahoe LT with 82,000 km on it, and all maintenance has been done at the Chevy dealer here in the UAE. After my last major service, I started noticing a strange humming noise when starting the car from a cold start.

The noise happens when I start driving but disappears within 2-3 minutes as the engine warms up. What’s odd is that if I turn off the car and restart it while it’s still warm, the noise doesn’t come back—probably because the engine is already at temperature.

I took it to the dealer since it’s still under warranty, but they said they couldn’t find any issues. They suggested recording a video of the noise, but I haven’t been able to capture it clearly.

Any recommendation guys on what i can say to dealer?
