I FOUND A BIG DESIGN FLAW IN OUR NEW MINIVAN. WHEN MY KIDS ARE USING THE REAR ENTERTAINMENT SYSTEM, THE SCREEN BLOCK THE DRIVER REAR MIRROR LINE OF SIGHT. I DON'T FEEL SAFE DRIVING AROUND IF I CAN'T HAVE BACK AND FORTH VISIBILITY FROM THE DRIVER SEAT. I DON'T UNDERSTAND WHY TOYOTA DIDN'T MAKE THE DIGITAL REARVIEW MIRROR STANDARD IN ALL THE TRIMS EQUIPPED WITH REAR ENTERTAINMENT SYSTEM. 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.
