Do you have s speed indicator signal? Check if you do. It may be set to sound when reaching a set speed.
Pop the hood look between the headlight and grill you will see the plastic piece that covers the radiator it's about two inches wide it comes out to the grill and headlight on both sides on my terrain this plastic piece starts buzzing at 60mph you can test this by putting tape over it or a small screw through the top of the plastic
having same issue, they changed the seal on the windshield, didn't fix, changed the entire windshield, didn't fix actually made it worse and now changed the cowl grill assembly, just got it back this morning, seems to be fixed, hope it stays that way. Guru9RMYZ, did you ever get yours taken care of and if so, what was the end result?
