(TMZ) Former "American Idol" judge Kara DioGuardi has been sued over a 2010 car accident that allegedly left one man with a terrible neck injury ... but the crazy part, Kara wasn't even driving the car!!!

The man doing the suing is Joel Postorino -- who claims he suffered a serious disc injury in his neck after a woman driving a 2005 BMW smashed into the back of his Porsche at an L.A. intersection last May.

In his lawsuit, filed in L.A. County Superior Court, Postorino claims the only person in the BMW during the crash was a woman named Christina Kline ... but Kara happens to be a registered co-owner of the BMW, so the man feels the former "Idol" star should have to pay up too.

DioGuardi's rep tells TMZ ... Kline used to work for Kara ... and she only co-signed on the car to help her employee out several years ago. more on this story
