My gen 1 dam scrapes all the time and after 4.5 years of doing that, there is minimal wear. I have had to reconnect the tabs a few times but that is pretty much it. The wear is remarkably slight compared to what I hear when it happens. I spray some tire cleaner on it when I wash the car and it always cleans up pretty well. It does not detract from the car at all in my opinion.

I do get a lot of people looking at me though when I back out of my driveway as it hits just the right way to make a pretty decent scraping sound and those around me think I have killed the car!

It is a bit of a nice warning sound though when pulling up to a parking lot curb or going over a speed bump.

I don't know how many times I have to yell at the wife to not put the front wheels against the concrete stop or a sidewalk edge, but that's what she learned when growing up. I park the volt at least 2-3 feet from those items to avoid scraping, but my wife can't kick the habit despite the volt being such a short car compared to the suburban. CTS, and Deville (the previous vehicles she drove).

I'd leave it on and not worry about the scraping noise.

I leave space too, but I am heading into Senior Status - which means curbs and parking lot blocks are fair game! I gave up long ago on telling the wife.
