“Toyota safety sense sensors randomly malfunction and flash false warning lights. My truck will tell me to brake and beep alarms at me even if nothing is in front of me. This has happened around 10 times, and one time my truck slammed on my brakes on the interstate for no reason. Luckily this was at night with no other vehicles around. Myself and many other folks have had serious issues with this system and Toyota does nothing to acknowledge the problem.”
NHTSA complaint #11187332, filed 2019-03, 6,000 miles“I purchased a 2018 Toyota, Tundra truck in 1/2018. On 3/5/19 at apprx 8 am. I assume an electrical fire started beneath the center console. While at a standstill, on my driveway, around 8 am, a fire started inside the Toyota.the fire could not be extinguished with water and continued to grow and only after a fire extinguisher was used was the fire extinguished. The flames had consumed the plastic in the center console to the automatic gear shift. The fire had run along the same path that the wire run which could be visually seen. …”

NHTSA complaint #11205585, filed 2019-05, 20,000 miles“Toyota's pre collision sensor is unreliable and intermittently produces an error pcs sensor unavailable -- clean sensor . The safety portion of this complaint comes when dynamic cruise control is set. When the sensor no longer detects a vehicle in front of you, and there is clearly there, the vehicle will accelerate at a high rate of speed before the error shows on the dash cluster if the cruise control is set above the traffic flow. I expect and realize that this situation could occur, and I avoid using the system. …”
NHTSA complaint #11080776, filed 2018-03, 2,500 miles“1st off, I drive a 2018 Tundra, my integrated trailer brake controller doesnt apply brakes on any trailer. It throws an error message and will not work on any trailer type settings. Had trailer checked and tested with other vehicles and trailer works fine. And of course the same exact issue is all over the internet since 2016 and up, with no fix or responibilites taken on toyotas part. Not habing trailer brakes is a very dangerous situation and believe that if I paid for the brake system I should have to buy an aftermarket one just to pull my trailers safely. …”
