THE LACK OF REAR VISIBILITY FROM THE DRIVER CAN PUT AT RISK THE LIFE OF ALL THE PASSENGERS. I TRIED CONTACT THE DEALER AND TOYOTA DIRECTLY BUT I'M NOT GETTING A RESOLUTION. THIS IS A SERIOUS DESIGN FLAW! TOYOTA SHOULD ISSUE A RECALL FOR ALL THE MINIVANS WITH REAR ENTERTAINMENT SYSTEM AND NO DIGITAL REARVIEW MIRROR. | Crash: No Fire: No | 940 |
