[RC8103]

2022 Limited 8k miles. Humming/buzzing noise between 40 and 65mph. Loudest at about 55. Dealer checked it out and said it’s not a mechanical issue and they want to start by replacing B pillar molding. Waiting on parts. I’m not too confident that’s the problem. Other than the noise it drives totally fine. No vibrations etc. Anyone got any ideas? Tires all appear fine but could it be a tire issue?

Have you looked though the threads here. An easily fixed solution may be what your problem is. Plastic cover each side of vehicle may have loose hand tightened nuts or the bolts are loose.

Yeah all those nuts underneath are all tight. The noise does seem to be coming from under the front. It’s very faint and sort of rotational at lower speeds and then becomes a very noticeable and constant hum or buzz at about 45mph.

Could be a tire. You could try rotating front to back. Do one side at a time to make it easier to pinpoint which side is making the noise.
