Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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”
NHTSA complaint #11118418, filed 2018-08, 2,500 miles“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. …”
NHTSA complaint #10926116, filed 2016-11, 100 miles“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.”
NHTSA complaint #10872967, filed 2016-06, 5,000 miles“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. …”
NHTSA complaint #10874031, filed 2016-06, 4,000 miles“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.”
