On several occasions, I've banged the bottom of my front end when backing out of a parking area where I have to go down a curb. And not even a big curb. If I back straight out of my driveway and into the street, the bottom of my front end hits the curb. The big "bang" sound makes me cringe! I no longer back straight out of my driveway... By the way, this doesn't happen with other cars. Also, yesterday I was pulling out of a parking lot. The exit to the parking lot sloped downward a bit and when my front end got to the street, it hit the pavement. I've looked under the car. No real damage that I can see and everything seems to be working ok. Has this happened to anyone else?
