I have a 2014 Cadillac CTS coupe that seems to have alot of wind noise around both windows, is this common for thes vehicles.
This is the first Cadillac I have owned, and thought it would be much quieter. I inquired at the dealer and they told me that this is common with these particular Cadillac's. I'm surprised to say the least.
Try driving a similar vehicle on a used car lot to see if it is normal for this car (I doubt it). Then see if you can narrow it down for the service rep. Does it have a roof rack? Are you sure it's wind noise and not tire noise? Your investigative efforts can help the service rep to narrow the problem for you.
