While descending a steep grade towing an 8,000lb travel trailer using appropriate hill descent braking techniques, an error message came on the dash indicating a trailer wiring, type, or connection fault. From this point forward, I had no trailer brakes and was left with truck brakes only. I got the truck/trailer combination to the bottom of the grade safely, however this could have been catastrophic for an inexperienced driver or in a different situation. Upon further investigation, this is a common problem with Toyota Tundra-??s, and acknowledged by Toyota in TSB # T-SB-0036-19 issued on April 1, 2019. The dealer and Toyota Customer Service will not acknowledge this, and states it is something only covered under the 3 year warranty. My question for you, the NHTSA, is how would this not be considered a safety issue, when the issue comes on unexpectedly under less than ideal circumstances, especially when Toyota has acknowledged that there is a problem with their brake controller. This is a safety issue, not a warranty issue. Toyota will be held accountable for any injury or death caused by my vehicle in this situation.

All of a sudden the pre-collision system malfunctions and stops working and the lights go on in the dashboard and then causes the cruse control to stop working as well. I took it to Toyota and they stated they did not know what the cause of it would be.

Check engine light came on and after scanning Code P2445 'Secondary Air Injection Pump Stuck Off' was the error. Vehicle went into lower power mode, which is very unsafe for highway driving. The Secondary Air Injection Pump issues have plagued Toyota V8's for many years and I had hoped they'd fixed the issue by the 2nd Generation Tundras, I guess not. Dealer replaced the Secondary Air Injection Pump for about $850 and noted that there was moisture in the pump, which caused it to short out - very similar to issues reported by other Toyota V8 owners. Toyota has a 10 year warranty on the Secondary Air Injection Pumps for 2007-2010 Tundras and 2008-2010 Sequoia models - but no other years/models. It's time that Toyota recall these vehicles and fix them properly, or extend the warranty to all years/models.

Toyota corporate as well as Toyota of Kirkland Washington failed to inform me of an open recall associated with my 2018 Toyota tundra pertaining to possible engine fire due to electrical failure in headlight assembly.

- Marquette , MI, USA

While driving, multiple warning lights come on and multiple warnings scroll on the dash. Transmission shifting becomes irregular, hard, slipping, pre-collision alert fails, adaptive cruise control fails, ABS system deactivates. I know of this occurring on multiple other Toyota vehicles as well. This has happened three times and only resolves when battery is disconnected. Weeks or months goes by and it recurs.

Vehicle was diagnosed with having a left rear speed sensor and speed sensor wire was broken due to a piece of plastic part came separated from the wheel. Have all kinds of lights come on dashboard and flash on and off, until sensor is replaced with new at an astronomical rate, which cannot be replaced at this time. Feel that the vehicle should be considered recalled for this issue, as the wire is just hanging there, attached to the wheel underneath and should be fixed and attached somewhere else, where it is not less likely to be pulled or disruptive on the future, by other vehicles like mine is. Should be on a recall list as I do not know if other Toyota owners are experiencing the same problem. The lights on the dashboard just blink off/on continuously, even when it starts and from the time the vehicle stops. Cannot see the speed on the dashboard when you are driving down the road.

I had 2 warning messages appear on the dash whilst driving: 1. trailer brake error (if towing come to a safe stop with manual controls.) contact dealer. 2. pre collision system malfunction. Visit your dealer. The messages would not clear, drove 80 miles (freeway) or so home, truck was running fine, no issues on that side, the following day I had the vehicle towed (aaa) due to the pre collision system failure error... I get a message from the dealer to say I have fuel contamination and it'll cost $1400 plus tank refill, no mention of the error codes that were on! apparently they said due to a mis-fire it throws those codes. I never felt and mis-firing while driving, we picked the truck up, filled half the tank added injector cleaner as a precaution......there were no running problems, the error codes have gone.... a electrical anomaly....

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 Toyota 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. 2nd issue is once again electrical, the radio shut on and off every 10 minutes or so...will not keep presets saved etc, told Toyota and they tried to download and update and said the radio wouldn't except the download. Of course truck is out of the horrible offered 30K mile warranty....so I have a 2018 Tundra 4X4 that has a broken radio and can't even pull a trailer.....hard to wanna make a payment for that kinda stuff.

Driving down the road the following lights came on the dash some of them flashing and loud beeping sound, also displayed the following errors on the center lcd. Lights: ABS, brake, 4lo, 4hi, hazard triangle, bsm, traction contol, rcta. Warning messages: Drive start control malfunction, visit your dealer. Blind spot monitor malfunction, visit your dealer. Trailer brake error, if toeing come to a safe stop with manual controls, contact dealer. Rear cross traffic alert malfunction, visit your dealer. When this happened I pulled over to a stop, placed the truck in park and turned it off. Waited 10 sec and turned it back on, same messages and lights were on. Aprox 30sec later all lights turned off and everything was back to normal.

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. We tried to move the vehicle a distance from a building but could not shift it forward only backwards. We contacted our insurance and after inspection they determined it was an electrical fire. There has been no after market additions to this vehicle. We contacted Toyota and the vehicle was towed to the dealership ON3/8/19. A claim was filed with Toyota (#1903113498) thereafter. It is now May 2018 and to date we do not have our car back nor know of the status of our claim. As an fyi the truck was serviced on 8/2018 and they advised us that they had to replace the truck battery with a brand new battery on this same new car - something about not keeping the charge. The fire was on 3/5/19 and it is now 5/3/19 and we have not been advised on the status of the vehicle. On one of the phone calls I was advised that it was at product liability. One my phone call today they did not know when I would have my truck back or the outcome of the investigation. The truck's approximate mileage was 20K. I was advised by my state's ag that I was obligated to report this incident to you. I would like answers and I would like my 2018 Toyota as it should be.

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.

Collision avoidance system engaged randomly with no known cause at location traveled on a frequent basis. At between 40-45mph on a sunny day at temperature in upper 60's and a location that I travel multiple times a week, the collision avoidance system engaged on the dash board. There were no cars, guard rails, trees or other major metal objects on or near the road at the time of the incident. Toyota service mgr indicates that there was no data logging of the event and technician was unable to reproduce; indicates that without 'evidance', they cannot make a repair. However, the evidence of intermittent sensor or computer failures is not always available if proper data logging equipment is not installed in the system. Previously, the collision avoidance system had been engaged by an oncoming bus in the adjacent lane (normal daily driving condition, no expectation of collision) at 30mph. Parking collision sensor (left front) was also triggered in minor snowfall at low speed in a parking lot. Vehicle was purchased new from dealer 12/2017 and had all scheduled services.

Pre-crash system does not work properly, with no vehicle in front of me while driving on the hwy, at times if a vegicle passes me on either left or right side, the crash warning beeped and brakes applied, note: No one is in front of me, this has happened a few times, since the initial recall for updates, my pre-crash system inticates its on, however, its not working, yesterday at about 2:15 pm on 8/27/2018 it failed and I hit someone in the rear and speed under 10 mph, I was told by fred anderson Toyota of sanford nc service department that they have had some that was out of calibration and that mine should have worked wether if cruise control is on or off.. well it doesn't not work, my truck goes into Toyota today 8/28/2018 at fred anderson Toyota to be checked again since the software recall update.

Pre-collision sensors. Pre-collision sensor has gone off twice advising me to brake. Both times there was no other vehicle around me nor was there anything to the sides or in front. Took it to the local dealership and they called Toyota corporate (?). was advised there's no fix and to continue driving the vehicle and annotate all factors surrounding my vehicle if it goes off again. Seems like an extremely unsafe alternative to finding out why a pre-collision sensor goes off. I should not feel unsafe driving my vehicle

Pcs system randomly turns itself off, rendering radar cruise control and other safety features useless. Started with less than 500 miles on the car. It has been in the dealership 3 occasions at this point with all updates completed and pcs light still illuminates on its own.
