2017 Toyota Tundra: headlights failing or too dim

Filed Jan 7, 2025 · Electrical, Lights · NJ

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.

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.

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

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.

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.

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.

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.

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.
