Turn Signal problems of the 2017 Toyota Tundra

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.

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. . Read more...

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.

When driving around at night and use the turn signal, the headlights will shut off and interior dash lights and radio lights will dim, as if it is day time. It typically happens in the mornings when it's cold out.

Purchased truck new in November 2016. . About a year later starting having rough starts and having to crank truck several times at cold start. Massive recalls for ecm and fuel pump however 17s not included. . . Also recently had front drivers side turn signal/running light replaced and still didnt work. Have read about this problem also. Local Toyota dealership unable to fix either problem.
