There was an accident in Houston where the Slingshot was upside down. The suspect failure may have been from a neglected Recall. The owner was suposed to know of a Brake Pin Recall for his Slingshot and elected not to get it looked at. No other details, here is an article about the recall and a diagram of the affected parts that are in question. Let's all promptly respond to any recall on our Slingshots. Don't figure you will skip it, it may be very important.
