Loss of power leaving driver stranded
While driving car, got warning to “Check electric vehicle system” quickly followed by “Stop vehicle and check power supply”. Car went into “Power Limited” turtle mode and speed dropped down to 25mph without warning. Was able to limp the mile and a half home but glad I was not driving on the interstate at high speed at the time. Dealer confirms ICCU failed and needs replaced, part backordered and no ETA on when it will be back in stock.
