2016 Toyota Tundra Exterior lighting Problems

My right front headlamp is getting moisture inside the headlamp assembly. It can be inspected any time. Chance that headlamp will not work. Did not take to a dealer.

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!!

HEADLIGHTS TURN OFF INTERMITTENTLY WHEN THE LEFT TURN SIGNAL IS USED AND THE HEADLIGHTS SWITCH IS IN AUTO MORE. DEALERSHIP CAN'T/WON'T REPLICATE THE ISSUE SO THEY WILL NOT TROUBLESHOOT FURTHER. THIS IS A PROBLEM THAT A LOT OF PLATINUM AND 1794 EDITION TOYOTA TUNDRAS ARE HAVING AND IT IS BEING IGNORED BY TOYOTA; HTTPS://WWW.TUNDRAS.COM/THREADS/AUTO-HEADLIGHTS-SHUT-OFF-WITH-TURN-SIGNAL.22968/ HTTPS://WWW.YOUTUBE.COM/WATCH?V=2TZRPLQ9WP4 I'VE HAD IT INTO THE DEALERSHIP TO CHECK AND THEY SAY THERE IS NOTHING THEY CAN DO. PICKUP ONLY HAS ABOUT 26K MILES ON IT. FIRST TIME IT HAPPENED WAS ON A FREEWAY CLOVERLEAF IN THE RAIN AND LUCKILY THERE WERE STREET LIGHTS BECAUSE I WAS IN THE MIDDLE OF A MERGE. OTHER TIMES IT HAS BEEN SIGNALING TO TURN LEFT AND ENTERING THE CENTER TURN LANE ON MULTI-LANE ROADS. ALWAYS HAPPENS WHILE IT IS DARK OUTSIDE BECAUSE THAT'S WHEN THE HEADLIGHTS ARE IN AUTO WHICH MAKES IT MORE DANGEROUS.

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!

ON MY 2016 TOYOTA TUNDRA 1794 EDITION, WITH HEADLIGHTS IN "AUTO" POSITION, WHEN I USE TURN SIGNAL, THE HEADLIGHTS, TAILLIGHTS AND DASH LIGHTS ALL OCCASIONALLY TURN OFF. ONCE TURN SIGNAL SHUTS OFF, LIGHTS COME BACK ON . IT TYPICALLY HAPPENS AT NIGHT WHEN IT'S COLD OUT. IT HAS NOW HAPPENED PROBABLY HALF A DOZEN TIMES IN THE LAST SIX MONTHS. WHILE PROBLEM IS INTERMITTENT, IT'S VERY SCARY, AS I'M DRIVING BLIND ON A RURAL ROAD UNTIL THE LIGHT COME BACK ON. ON THE TUNDRAS.COM OWNERS WEBSITE, THIS APPEARS TO BE A COMMON ISSUE. HELP! BEFORE SOMEONE GETS HURT.

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.

I HAVE A SERIOUS SAFETY CONCERN REGARDING THE LACK OF DAYTIME VEHICLE INSTRUMENT ILLUMINATION ON MY NEW 2016 TOYOTA TUNDRA (WHILE DRIVING, STATIONARY AND ON ALL ROADS) DURING THE DAY. AS AN ELDER ADULT WHO WEARS SUNGLASSES TO PROTECT THEIR EYES (ON THE RECOMMENDATION OF THE MEDICAL PROFESSION) THE DASH BOARD (SPECIFICALLY THE SPEEDOMETER INDICATOR) IS BARELY DISCERNIBLE. EVEN WITHOUT SUNGLASSES THE INSTRUMENT PANEL IS VERY DARK. I AM SURE THERE ARE THOUSANDS OF OTHERS WHO WOULD LIKE TO SEE THE INSTRUMENTS AND OPERATE THEIR VEHICLES IN A SAFE AND LAWFUL MANNER DURING THE DAYTIME OR WITH SUNGLASSES ON. I AM SURE THE DECISION, BY TOYOTA, TO NOT ILLUMINATE THE DASH IN THE DAYTIME SAVES A FEW PENNIES AND ADDS UP FOR THE MANUFACTURER WHEN YOU SELL THOUSANDS OF VEHICLES? BUT. . . NOT BEING ABLE TO SEE A DARK INSTRUMENT PANEL IS BOUND TO CAUSE MORE THAN A FEW ACCIDENTS.

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.
