Some owners of 2006-2009 Scion tC or 2008-2009 xD models may experience multiple warning lights illuminated. Also, the transmission will not shift from Park to Drive, and other accessories may become inoperative after the vehicle has cold soaked in sub freezing temperatures.
A newly designed IG1 relay has been made available to improve this condition.
