2017 Toyota Tundra ELECTRICAL SYSTEM,EXTERIOR LIGHTING

Headlights go out randomly usually when using turn signal. Because this happens at night all visibility is lost temporarily. This also confuses other drivers. I haven’t taken the vehicle to the dealer because the symptom is very sporadic and difficult to duplicate. Dealerships will not fix anything unless they can witness the issue. No warning lights or messages were displayed. This problem has been documented numerous times by many different owners on Toyota Tundra forums.

Headlights, taillights and all dash and interior lights go out when using turn signal at night. My and others safety has been put at risk due to the loss of headlights and taillights when engaging the turn signal. Those in my truck as well as those in surrounding vehicles are at risk because of the lack of exterior illumination while driving. Toyota dealer has not been able to reproduce the problem as the technicians do not work at night to drive the truck in the dark when headlights would be in use. Vehicle has not been inspected by any third parties just the dealership. There were no waring or messages or other symptoms of the problem before the failure. Problem first appeared in January 2022 and has occurred on over 6 occasions before truck was taken to dealership in February 2022. Truck was taken to dealership after lights went out at 70 MHP when signaling to exit highway at night.

When driving at night, the front lights of the vehicle turn off randomly. Been driving on an highway at going at 75mph and randomly the headlights shuts off. Happened 4 times in the past year.

Right headlight leveling motor failed causing headlight to point at the ground. I now have limited night time visibility on a 13,000 mi. vehicle. Toyota does not offer a replacement part nor do aftermarket sellers. A Youtube video of one of these dismantled motors shows a cheapest of the cheap device. Auto manufacturers should not be allowed to use cheaply made items to point headlights! Dealer refused warranty and wants $500+ for a new headlight that will last 13,000 mi. When the left side fails, I will no longer be able to drive at night. This is beyond absurd that a manufacturer is allowed to use the cheapest parts possible on a safety device such as a headlight.

WHILE DRIVING AT NIGHT AND THE LIGHTS ARE ON AUTO, PRESSING DOWN FOR THE LEFT SIGNAL THE HEADLIGHTS GO OUT AND THE DASH BECOMES DIM AS IF I AM DRIVING DURING THE DAY WHICH IM NOT. THE VEHICLE IS MOVING WHEN THE LIGHTS GO OUT . PLEASE FIND A RESOLUTION BECAUSE THIS IS DANGEROUS AND COULD CAUSE OTHERS TO COLLIDE WITH ME WHILE ON THE ROAD.

AUTOMATIC HEADLIGHTS SHUT OFF WHEN TURN SIGNAL IS USED. IT HAPPENS INTERMITTENTLY, BUT FREQUENTLY. I HAVE HAD THIS HAPPEN MULTIPLE TIME AT SPEEDS RANGING FROM 10 MPH TO 80 MPH BUT IT ONLY SEEMS TO HAPPEN WHEN THE AUTOMATIC HEADLIGHTS ARE ON AND THE TURN SIGNAL IS ACTIVATED.

WHEN OPERATING THE VEHICLE WITH THE HEADLIGHT STALK/SELECTOR ON "AUTO", THE DASH LIGHTS AND HEADLIGHTS SUDDENLY GO TOTALLY BLACK OR OUT. I'M ABLE TO TURN THE LIGHTS BACK ON BY MOVING THE SELECTOR TO "ON". THE PROBLEM IS IT HAPPENS AND SOMETIMES YOU DON'T KNOW ALL OF YOUR LIGHTS ARE OFF WHEN DRIVING, ESPECIALLY IN THE CITY WITH OTHER BRIGHT LIGHTS. THIS CAN BE VERY DANGEROUS. THIS HAS HAPPENED SEVERAL TIMES, SO I NO LONGER USE THE AUTO FUNCTION ON MY STALK...TOO DANGEROUS. *TR

HEADLIGHTS FLASH OR TURN OFF WHEN USING THE TURN SIGNALS. DASH LIGHTS ALSO DIM. SEEMS TO HAPPEN WHEN I USE THE LEFT TURN SIGNAL. HAS HAPPENED SEVERAL TIMES. IF I TURN THE SWITCH TO THE OFF POSITION THEN BACK THEY HAVE TURNED BACK ON.

WHEN THE SIGNAL STALK IS PLACED ON AUTO AND IT IS CLEARLY DARK OUTSIDE THE HEADLIGHTS WILL INTERMITTENTLY TURN OFF WHEN PUTTING THE LEFT TURN SIGNAL INTO PLACE. THE LIGHTS WILL COME BACK ON WHEN THE SIGNAL STALK IS BACK IN THE NEUTRAL POSITION. THIS HAS HAPPENED WHILE IN MOTION, STATIONARY, AND AT DIFFERENT OUTSIDE TEMPERATURES. HOWEVER, I HAVE NOTICED THIS OCCURS MORE WHEN THE TEMPERATURE IS IN THE 40'S.

I HAVE A 2017 TUNDRA AND WHEN I USE MY TURN SIGNAL IT MAKES MY HEADLIGHTS AND MY DASH LIGHTS GO OFF. I HAVE RESEARCHED THIS ON THE INTERNET AND FOUND A STREAM THAT THIS IS A PROBLEM WITH A LOT OF THESE TUNDRA'S ARE HAVING THIS ISSUE. MY LIGHTS HAVE GONE OUT WHEN DRIVING AT NIGHT AND THIS IS A SAFETY HAZARD. I HAVE INCLUDE A LINK TO A BLOG OF A TON OF OTHER OWNERS THAT ARE HAVING THE SAME ISSUE. THIS NEEDS TO BE LOOK INTO BEFORE SOMEONE IS KILLED. HTTPS://WWW.TUNDRAS.COM/THREADS/AUTO-HEADLIGHTS-SHUT-OFF-WITH-TURN-SIGNAL.22968/

DRIVING AT NIGHT WITH HEADLIGHTS ON IN AUTO POSITION ALL LIGHTS SHUT OFF AS IF THE SWITCH WAS TURNED TO OFF. THIS HAPPENS USUALLY WHEN TURNING. A TAP ON THE TURN SIGNAL STALK / HEADLIGHT SWITCH BRINGS THEM BACK. IMPOSSIBLE TO RECREATE. THIS IS VERY DANGEROUS. THIS HAPPENS MONTHLY.
