Scott Disick is suing Mercedes-Benz.

The Keeping up with the Kardashians star has filed a lawsuit against the auto company, alleging it sold him a "virtually useless" 2012 Mercedes-Benz SLS AMG because the vehicle is constantly breaking down.

In legal documents, obtained by gossip website TMZ.com, the 30-year-old failed restaurateur said that the car, which costs $190,000 new, is unreliable and has spent more time in a repair shop in Los Angeles than on the road. Scott is accusing Mercedes-Benz of failing to make the car roadworthy after numerous attempts and is seeking a full refund plus expenses.

News of the lawsuit comes after a difficult few months for Scott, whose father, Jeffrey Disick, died in early January, less than three months after his mother, Bonnie, passed away from cirrhosis of the liver. "[Scott is] very, very sad. The whole family is trying to comfort him. Everyone's upset. To lose both parents so close together, it doesn't seem fair," a source close to the star said.
