2017 Toyota Tundra Electrical System

THE HEADLIGHTS AND THE INTERIOR LIGHTS TURN OFF WHEN I USE THE TURN SIGNALS. THIS HAS HAPPENED SEVERAL TIMES SINCE I HAD THE TRUCK, THE LAST TIME THIS HAPPENED THE LIGHTS WERE OFF FOR ABOUT 5 MINUTES. THE TRUCK IS BEING LOOKED AT BY THE DEALERSHIP BUT THEY CAN'T RECREATE THE ISSUE. THIS IS A SAFETY PROBLEM

WHEN ENABLING THE REAR DEFROSTER (AND SIDE MIRROR DEFROST), I HEARD A LOUD POP, AND NOTICED SMOKE UNDER THE PASSENGER WINDSHIELD WIPER. THE WINDSHIELD HAD CRACKED (PRESUMABLY FROM THE HEAT DIFFERENTIAL), AND THE WIPER STARTED TO MELT ON THE WINDSCREEN. THERE APPEARS TO BE AN ELECTRICAL SHORT DIRECTLY UNDER THE WINDSHIELD (AND UNDER THE PASSENGER WIPER) THAT IS RELATED TO THE DEFROSTER. THIS OCCURRED WHEN THE VEHICLE WAS STATIONARY, AND COLD (MORNING STARTUP).

DASHBOARD GAUGES DO NOT ILLUMINATE DURING THE DAY WHEN THE HEADLIGHTS ARE OFF. BECAUSE OF THIS, IT CAN BE VERY DIFFICULT (OR IMPOSSIBLE) TO READ THE GAUGES WHILE DRIVING IN SHADY AREAS, ESPECIALLY WHILE WEARING SUNGLASSES.

MY 2017 TOYOTA TUNDRA 1794 CREWMAX, DURING WINTER MONTHS IN SOUTH CAROLINA - THE HEADLIGHTS, TAIL LIGHTS AND INTERNAL INSTRUMENTATION WILL TURN OFF WHEN TURNING LEFT OR RIGHT WITH TURN SIGNAL ENGAGED. THIS ONLY HAPPENS WITH THE LIGHTS IN THE AUTO POSITION AND NOT IN THE MANUAL POSITION AND THE ISSUE OCCURS AT NIGHT INTERMITTENTLY WHILE THE VEHICLE IS IN MOTION!! SOMETIMES THE LIGHTS JUST FLICKER AND SOMETIMES THEY GO OFF AND STAY OFF. I HAVE ALMOST RAN OFF THE ROAD TWICE WHEN THIS HAS HAPPENED. IT HAPPENS MORE FREQUENTLY WITH COOLER TEMPERATURES. I HAVE HAD THIS ISSUE FOR OVER A YEAR NOW TRYING TO GET TOYOTA TO FIX IT. THIS IS A KNOWN ISSUE THAT TOYOTA DOESNT WANT TO FIX UNLESS THEY CAN DUPLICATE THIS ISSUE IN THE SHOP, IN WHICH THEY USUALLY CANT. THERE ARE MANY PEOPLE ONLINE COMPLAINING OF THE SAME ISSUE, ON FORUMS. THIS IS A SAFTEY ISSUE THAT NEEDS TO BE FIXED ASAP.
