The Post-Dispatch reports that a couple from Pacific, Missouri and a Belleville, Illinois man have filed suit against Fiat Chrysler (archived) over security vulnerabilities in their vehicular entertainment system which can adversely affect the safety of motor vehicles with the system installed. The suit was filed in the US District Court in East St Louis on Tuesday and it includes Harmon International Industries, the maker of the entertainment system as a co-defendant. The plaintiffs are aggrieved that the impact of the security vulnerability has diminished the value of their vehicles and further means they over paid for the initial purchase. If the plaintiffs win this case it may open up most current computer manufacturers to claims for diminishing the value of computing products purchased by customers for including Microsoft Windows and other irredeemably flawed components.
