Has anyone noticed their GCL does not seem particularly quiet inside? We have a Summit Reserve with the 21" tires (Continental Cross Contact 275/45/21). My decibel X app at 70,mph reads between 80 and 82db on various non-concrete surfaces. My 2020 GMC Sierra with ANC maxes at 78db on the same surfaces, so this thing isn't as quiet as a truck. Is it possible the Active Noise Control in my car is not working? Does these vehicles seem loud to others? Could it be these Conti tires are noisy? I plan to have the dealer check it out but since it isn't throwing any codes we see, I suspect they'll say it is normal.
