I bottom out all the fucking time on driveways. I won't even touch the gas BOOM bottomed out -_- Thought I ripped my fucking bumper off today.
Did that pulling out of a 7-11 a few weeks back and heard a big thump. Bugged me so bad driving down the road I pulled over to see if I had done anything LOL All was fine though, not sure about underneath however, but I had the car at the dealer since and they didn't say anything.
