Problems with 2016 Toyota Tundra ELECTRICAL SYSTEM

All lights (headlamps and tail lamps and instrument panel) turn off when using turn signal. this typically happens when changing lanes at highway speed. i am not the only one experiencing this problem. seems to occur in 2015-2017 toyota tundras (1794 & platinum editions). see thread. https://www.tundras.com/threads/auto-headlights-shut-off-with-turn-signal.22968/page-3

Lock actuator went out on truck after only 2 years. per dealer this is a known issue. found online that it is very common in newer toyota vehicles and often occurs on all 4 doors. costly to repair and should not go out that quickly.

Low note electric horn intermitten failure: the low note electric horn becomes inoperative below 25 degrees fahrenheit while pressing the steering wheel horn pad/switch. the high note horns operates during this. i have had several close call encounters driving on the road where i needed the horn during these periods of low temperature and the horn didn't provide adequate audible warning. i have brought this up to my local dealership and they were "unable to duplicate customer concern". this is a $50 part that should of been replaced under good will if problem could not have been duplicated even when i provided video evidence of the horn inoperative. i do not feel safe driving a vehicle that is under warranty and still making payments on with an inoperative horn. i can provide the necessary dealership invoice to nhtsa upon request.

The vehicle was struck by lightning on 8/13/17. the dealership where we bought this vehicle new agreed to fix it through our insurance claim and provides a lifetime warranty on the repairs. the vehicle continues to have problems. see the attached list of damages, which were provided to the dealership on 1/15/18. when i dropped it off i indicated the vehicle was malfunctioning again without the cruise control engaged. the dealership called today and very rudely stated they could not recreate the problem and will not fix the vehicle. the vehicle is unsafe to drive because of some of the issues. when i asked to speak to the customer service manager, the receptionist refused and said they will not fix my vehicle.

I purchased a new trailer to pick up my new tractor. i tested the trailer brakes knowing i was pulling a large load and didn't want an accident. the brakes appeared to apply but due to it not being loaded when testing i had it set to 5(out of 10). while pulling it back home on the interstate towing my tractor behind me there was traffic stopping ahead. i always drive in the right lane to not slow others...thank god i did. i had to drive off the road onto the shoulder to miss hitting or driving over cars ahead of me! the brakes turned up to 10 did nothing to even slow me down. i was towing 4 tons and 3 tons for the truck totaling 7 tons, someone would've been killed! toyota needs to fix these trailer brakes! i can't tow my tractor anywhere for work due to the brakes being unsafe!

The trailer brakes will not operate correctly. the trailer brakes will not lock up even when set on 10. very dangerous when hauling any trailer with breaks. i have put my other truck to the trailer and it operates great. it is absolutely the break control from the factory not the trailer

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.

The integrated elecric brake controller included in my platinum edition options for towing a trailer does not work. according to dealer, there is no fix from toyota although they are aware of the issue.

I bought a 2016 tundra in may of 2016. i own some ranch property in west texas. i have taken the truck there twice and both times i have had wiring damaged by rodents. so far it is up to over 800 dollars. toyota will not warranty it.

The integrated elecric brake controler for towing a trailer does not work.

Tl* the contact owns a 2016 toyota tundra. while towing a trailer, the brake pedal was depressed; however, the trailer brake lights failed to illuminate. the vehicle was taken to an independent mechanic where it was diagnosed that the integrated brake controller failed and needed to be replaced. the vehicle was not repaired. the manufacturer was notified of the failure. the failure mileage was approximately 500. the vin was not available.

While trailering my 6800 pound travel trailer for the first time and after i had manually set the factory electric brakes, a car pulled out in front of me and the electric brakes would not stop my trailer or even slow it down. the brakes were set at an 8.5 on the readout. i came within inches of an accident at about 45 mph. next, the brakes were adjusted all the way up to a setting of 10. this also did not help to stop the truck and trailer with braking hard at various speeds. i reported this to the dealer after i had tried several other times to adjust the brakes with no success. at this point, i am awaiting toyota to come up with a fix before someone is killed or injured. this issue is wide spread across tundra forums online.

On my 2016 toyota tundra platinum edition, at night 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. them is intermittent, this is so scary! i was going down the freeway at 80 mph at night and my truck (full of my family) just disappeared when i changed lanes. i have taken my truck in 3 times now and toyota can't replicate so they says they can't fix it. please help! before someone gets hurt.

Electric brake controller doesn't work properly. several people have already contacted nhtsa on this problem.

The integrated brake controller is not work when applying the brakes in electric brake mode. took my tundra out for a test drive with my 24' 3200 lb travel trailer. i set the gain to 10 and hit the manual slide and the trailer tires locked up. stepped on the brakes and couldn't feel any brakes being applied to the trailer. i would have expected the trailer tires to lockup when i hit the brakes with a gain of 10. this could make a very dangerous situation.

Re: integrated break controller i wanted to express a serious safety concern i have with an item that now ships with the 2016 toyota 5.7l tundra's - the built in / integrated break controller for use when pulling trailers/campers/etc. it seems that regardless of the power setting, no noticeable power is supplied to the trailer brakes, even at it's highest setting. it feels like the trailer/camper is pushing the truck, which can be a serious issue when stopping. this would happen every time i would tow and i was always very worried about causing an accident if i needed to stop quickly or if the road conditions were not idea. i've never felt this with other break controllers. it's my understanding toyota has not acknowledged this as being an issue yet. after talking to many other tundra owners everyone has the same issue, i've not talked to anyone that has a working integrated break controller in their 2016. i've taken out my integrated break controller that came in my 2016 toyota tundra and replaced it with an after market brake controller out so i can property brake with my camper attached. for now my issue is resolved, however, i am however very worried about others that might be using the integrated break controller and the huge potential for a serious accident because their trailer or camper brakes are not working. please look into this before any serious accidents happen. thanks!

Tl* the contact owns a 2016 toyota tundra. the contact stated that the trailer brake controller malfunctioned, which resulted in little to no assistance from the trailer brakes even when the vehicle brake pedal was depressed. the contact stated that the trailer brake was only operable once the vehicle was set into manual override mode. the vehicle was taken to the dealer where it was diagnosed that the trailer brake controller was defective and needed to be replaced. the brake controller was repaired, but the failure still occurred. the manufacturer was notified. the failure mileage was approximately 550. updated 06/21/16*lj *tr
