Hybrid battery failure. Battery issue can cause car to lock up while driving. Dealer service department indicate they have at least 6 vehicles with this same issue. The vehicle has not been inspected by other than the dealership service department that I am aware of. While driving to the dealership for a routine oil change, the car made a quick odd noise then 3 alerts came on said Hybrid system malfunction have vehicle inspected, engine malfunction, system malfunction. Dealer inspected vehicle determined needed a hybrid batter replacement, indicated they could not say vehicle was safe to drive as it could just stop working. Considering they already have a number of cars with same issues in the shop I am concerned this could be a defect problem in many vehicles.
