While in motion- blind spot sensors turn on when they should not and vice versa. Traction control has failed multiple times while driving. Predictive braking has activated improperly multiple times while driving. Cameras went out and then battery completely died. Was told fixing battery would fix vehicle. This has proven to be untrue. Vehicle is currently in for service for third time. Remains under warranty, as I have had it three months. Most recent date has been used but I've had problems since literally the first full day I have had it.
