We love our new Lucerne, except for the air noise that comes in through the windows. We purchased it for fuel economy, comfort and the advertised guarantee of quietness. We average about 24 MPG on the road and it is comfortable. But the door/window design must be flawed because the air noise that comes through the windows at speeds over 45 mph is awful. It is like driving in a wind tunnel. The dealership promises to replace the gaskets around both of the front doors, so we hope that this helps. Just make sure that you test drive on a highway where you can drive over 45 MPH before you buy this vehicle.
We love the color and the OnStar features. The back seats are actually more comfortable that the front. There is a lot of leg room. It handles well. In fact, we love everything about the car except for the window air noise. Once that is fixed, we will recommend this car to everyone.
Buick needs to re-exam the cause of the air noise that comes from the windows at speeds over 45 MPH.
