2016 Toyota Tundra Lights Problems

Your right front headlamp has moisture building up inside the assembly, which could potentially cause it to stop working. This is a cosmetic and functional concern that can be inspected at any time. The fix will likely involve replacing the headlamp assembly or resealing it to prevent moisture entry.

HEADLIGHTS IN THE ON OR AUTO POSITION RANDOMLY GO OUT WHEN BLINKER RETURNS TO NEUTRAL POSITION AFTER BEING ENGAGED. THIS HAS HAPPENED WHILE IN MOTION AT LOW AND HIGHSPEEDS ON CITY STREETS AND HIGHWAYS AND COMING OUT OF A COMPLETED STOP. CANNOT DETERMINE IF THIS IS A SHORT IN WIRING HARNESS OR IF TRIGGERED BY FAULTY COMPONENT.

HEADLIGHTS, TAILLIGHTS, AND DASHLIGHTS ALL GO OFF WHEN USING THE TURN SIGNAL. THIS HAS HAPPENED HALF A DOZEN TIMES AT NIGHT WHEN THE TEMPERATURE IS IN THE 30'S, BOTH WHEN TURNING ON NARROW UNLIT RURAL ROADS, AND ON THE INTERSTATE AT 75MPH WHEN CHANGING LANES. IT IS A COMMON PROBLEM WITH THE 1794 EDITION OF THE TUNDRA WITH THE AUTOMATIC HEADLIGHTS. YOU CAN FIND DOZENS OF OTHER TUNDRA OWNERS WHO HAVE EXPERIENCED THIS PROBLEM, INCLUDING A VIDEO ON THE TUNDRA.COM WEBSITE. SEE LINK BELOW: HTTPS://WWW.TUNDRAS.COM/THREADS/AUTO-HEADLIGHTS-SHUT-OFF-WITH-TURN-SIGNAL.22968/ THIS IS EXACTLY WHAT HAS HAPPEND TO ME, AND IT IS SCARY DANGEROUS. I REPORTED THIS TO NHTSA BACK IN DECEMBER, AND TOYOTA HAS YET TO DO ANYTHING ABOUT IT. THEY HAVE NOT EVEN ISSUED A SERVICE BULLETIN. PLEASE GET THEM TO FIX THIS! EVEN MY TOYOTA SERVICE AGREEMENT WON'T FIX MY TUNDRA, BECAUSE THE DEALER CAN'T REPLICATE THE PROBLEM (IT'S NOT COLD, AND THEY CLOSE AT 6 WHEN IT'S NOT DARK!), AND THERE IS NO SERVICE BULLETIN OR ANYTHING FROM TOYOTA ACKNOWLEDGING THIS IS EVEN A PROBLEM. I'M BEGGING YOU, AT LEAST GET TOYOTA TO ACKNOWLEDGE THERE IS A PROBEM AND FIGURE OUT HOW TO FIX IT!!

THE HEADLIGHTS AND INTERIOR DASH LIGHTS RANDOMLY TURN OFF WHEN USING THE BLINKER. I HAVE OWNED THIS TRUCK FOR 3 MONTHS NOW AND IT HAS HAPPENED ON FOUR DIFFERENT OCCASIONS. I CANNOT REPLICATE THIS ISSUE ON MY OWN.

WHILE DRIVING AT NIGHT, THE ACTIVATION OF TURN SIGNAL INTERMITTENTLY SHUTS OFF HEADLIGHTS. TO RE-ENERGIZE HEADLIGHTS I HAVE TO MANUALLY SWITCH THE HEADLIGHT SWITCH FROM AUTO TO ON. THIS IS VERY DISTURBING AND DANGEROUS WHILE DRIVING AT NIGHT IN RURAL AREAS. I AM HOPING SOMEONE ADDRESSES THIS WITH TOYOTA, SINCE IF THEY CAN'T REPLICATE THE ISSUE THEY SEND YOU HOME!

IF THE HEADLIGHTS ARE SET TO AUTO AND I SIGNAL A LEFT TURN AND TURN TO THE LEFT, THE HEADLIGHTS SHUT OFF AND THE INTERIOR LIGHTS SWITCH TO "DAY MODE". THE ISSUE SEEMS INTERMITTENT. IT SEEMS TO OCCUR IN COOLER TEMPS (<50F).

WHEN ENGAGING TURN SIGNAL, ALL LIGHTS EXTINGUISH MOMENATARILY. THIS IS AN INTERMITTEN AND HAPPENS AT RANDOM, BUT NOT CONSTANT. THE FIRST TIME I NOTICED WAS EARLY MORNING BEFORE SUN RISE I WAS IN A TURNING LANE AT A RED LIGHT STOPPED, ENGAGED LEFT TURN SIGNAL AND ALL LIGHTS WENT DARK. THE NEXT TIME I WAS ATTEMPTING TO MERGE AND ENGAGED TURN SIGNAL IN TRAFFIC ALL LIGHTS WENT DARK. I SEARCHED THE INTERNET FORUMS TO FIND THIS IS A COMMON OCCURENCE WITH TUNDRA PLATINUM AND 1794 MODELS. MY VEHICLE HAS NO MODIFICATIONS AND ALL LIGHTING IS FACTORY INSTALLED.

WHILE DRIVING AT NIGHT TIME, THE WHOLE LIGHTING INCLUDE HEADLIGHT AND INSIDE LIGHT LIKE ODOMETER SCREEN, NAVIGATION SCREEN COMPLETELY BLACK OUT FOR FEW SECOND SOMETIME NEAR A MINNUTE. ITS ONLY HAPPEN WHEN THE BLINKERS ITS USED.

BOUGHT NEW 2016 TUNDRA LIMITED 11/16/2015 AND NOTICED THAT DASH LIGHTS DO NOT COME ON DURING DAYLIGHT HOURS UNLESS PARKING LIGHTS OR HEADLIGHTS ARE ON. IN THE OFF/DRL POSITION OR THE AUTO POSITION NO DASH LIGHTS. WHEN I CALLED TOYOTA HELP LINE I WAS TOLD THAT THIS CHANGE WAS MADE BECAUSE IF THE DRIVER CAN SEE THE OUTLINE OF THE NUMBERS ON THE GAUGES THEY DO NOT NEED TO BE ILLUMINATED. HE COULD NOT OFFER ANY REASON FOR CHANGING THIS STANDARD FEATURE. OTHER THAN NOT SEEING THE GAUGES SHARPER AND CLEARER ONE SAFETY DEFECT IS PRESENT. THE TUNDRA HAS GAUGES INSTEAD OF WARNING LIGHTS FOR ENGINE OPERATIONS AND THEY ARE SMALLER THAN THE SPEEDOMETER/TACHOMETER . THE TEMP GAUGE IS LOCATED ON THE LOWER LEFT OF THE DASH AND CANNOT BE SEEN CLEARLY WITHOUT THE DASH ILLUMINATED BECAUSE THAT CORNER IS DARK IF IT IS CLOUDY OR EARLY OR LATE . IF THE ENGINE OVERHEATS ONE WOULD NOT SEE THAT PROBLEM ON THE GAUGE WHICH MIGHT LEAD TO ENGINE FAILURE ,ETC. I HAVE NEVER OWNED A VEHICLE THAT REQUIRED TURNING ON THE PARKING LIGHTS OR HEADLIGHTS TO ILLUMINATE THE DASH..DEALER SAYS THAT SWITCH CANNOT BE CUSTOMIZED. TOYOTA SHOULD ISSUE A FIX FOR THIS MISTAKE.
