Windshield Crackling Noise

bradcc

Not long after I got the car, I started noticing a crackling noise from the windshield when I have to drive the car on/off a driveway/gas station ramp at an angle. I talked to a guy at the service department at a dealership and he said it's because the windshield bends as the car body flexes as I drive through bumps or ramps.

My question is, is this normal? I've never experienced anything like this out of all the cars I've driven(hundreds of them..). I kinda put this off my mind since it's not a constant noise. However, as I pulled into my driveway today as I usually do, I actually heard crackling noise from the body of the car.

Should I be concerned about the rigidity of the car and if there is any fix for this? The car handles well so I don't think it's on the verse of falling apart. But it's just really annoying to hear these noises that should not exist in a 30k car with less than 8k miles!
