Brand new 2023 Equinox with horrible reverb at 35-37 mph, when we took it home I thought a big stereo system was passing us. Dealer has had it for four days now, we took the tech for a ride to let him hear it, he said definitely not right, thinks it’s in the tranny while in 5th gear, long story short, they called today and said that’s normal. WOW! Anyone else having issues or any ideas?
