2023 GMC Canyon Denali Whistling/Squealing Windshield Noise

[Collin Norman]

Experiencing a whistling/squealing noise coming for the top of the drivers side windshield when driving over 70mph. Just took it in to GMC service and they said it is most likely that the windshield glass needs to be re-set. Problem is they need an additional windshield when performing the re-set in case the current one breaks and since the truck is brand new and it is a new body style, there are no windshields available to order. No telling when this problem can be fixed. So I've got to live with a super annoying sound for the unforeseeable future. 

 

Also, the moulding around the wiper arms are not connected to the additional moulding near the hood hinges. The clips are literally not connected at all and will not set back in place. Have to order all new parts for that as well...brand new truck. Unbelievable.

I have the same issue and was told it was a cowling that needed replacing. Keep us posted if the reseat of the windshield makes a difference.

I have a new 2023 GMC Canyon AT4 doing the same thing. At speeds above 70mph it comes and goes (very annoying!). I took it to the dealer and they confirmed it was coming from the passenger side upper corner of the windshield/molding area. Since the parts on on backorder, all that they could do was open a trouble ticket with GM. I did add some silicone caulking around the corners which seemed to help but did not totally eliminate the noise.
