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.
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.
With the headlight switch selected to �auto� and when engaging the turn signal to the left durning night driving, all exterior and interior lights would go black until turn signal switch is moved to the on the position. Vehicle was taken local Toyota dealership service department to remedy the issue. Initially, this dealership thought it was the light sensor located on the dash of the truck and replaced it using a warranty claim. Almost immediately (next day), the vehicle repeated the same initial failure over 3 times in an hour. I made an appointment with that same Toyota dealership but upon arrival I was met with resistance due to a previous warranty claim for the same issue. They advised me if I wanted the switch replaced, it would be totally at my expense. I left that dealership and proceeded to another Toyota dealership who replaced the switch at my expense. The replacing of the switch has solved the lights going out while driving during the night. I've read on several truck forums that this is a known issue by Toyota but they haven acknowledged it. Luckily, I can afford to replace my switch to ensure my family is safe in this vehicle but my submission here is for those that can't afford the replacements and need Toyota to issue a recall to fix this serious but inexpensive issue.
