The National Highway Traffic Safety Administration’s (NHTSA) Office of Defects Investigation (ODI) have opened a preliminary evaluation (PE13-013) into certain 2012-2013 Ford Focus electric vehicles after receiving thirty complaints of the vehicles shutting down while driving. The complaints show an increasing trend, with most received within the past five months.

According to the investigation report approximately fifty percent of the incidents occurring at speed of 30 mph or more. Ford and the NHTSA will be focusing on the power-train and all supporting power electronics, sensor, control modules, software, wiring and other components manufactured as original equipment or service replacement parts in the subject vehicles. There have been no complaints alleging that the problem resulted in a crash or injury.
