The contact's son owns a 2026 Toyota Tundra. The contact stated that while his son was driving 65 MPH after the rain had stopped, the turn signals failed to operate, and the windshield wipers failed to turn off. The Forward Collision Avoidance warning light was illuminated. The failure was a recurring failure. The dealer was contacted. The dealer diagnosed the vehicle with steering angle sensor failure. The sensor was replaced and the vehicle was repaired. The failure mileage was approximately 18,000.

The Forward Recognition Camera on my 2019 Toyota Tundra has suffered an internal failure. The vehicle was inspected by an authorized Toyota dealership, which diagnosed and documented:"FOUND INTERNAL FAULT IN FORWARD RECOGNITION CAMERA." The failed component is available for inspection. This camera is a critical safety component that supports forward collision warning, automatic emergency braking, and other driver-assistance systems. Because of this internal failure, the vehicle's ability to detect potential hazards may be reduced or disabled, leaving the driver without safety features that were designed to help prevent or mitigate crashes. This failure places not only the occupants of my vehicle at risk but also other motorists, pedestrians, and cyclists sharing the roadway. The condition was reproduced and confirmed by an authorized Toyota dealer. The dealer determined that the camera itself had internally failed and requires replacement. The failure was not attributed to an accident, impact, misuse, modification, or outside damage. It was diagnosed as an internal fault of the camera assembly. Prior to diagnosis, warning messages and safety-system malfunction alerts appeared on the vehicle, indicating that the driver-assistance systems were not functioning properly. These warnings prompted me to seek service. The dealership subsequently confirmed the internal camera failure. I am concerned that this component failed under normal operating conditions in a relatively modern vehicle and that other Toyota Tundra owners may be experiencing the same defect. A safety-critical camera system should not experience an internal failure that disables key crash-avoidance technologies. I am requesting that the federal safety agency investigate whether this defect is affecting other 2019 Toyota Tundra vehicles and determine whether corrective action, including a recall, is warranted. The dealer diagnosis specifically states:"FOUND INTERNAL FAULT IN FORWARD RECOGNITION CAMERA."

I own a 2024 Toyota Tundra 1794 Edition with approximately 37,000 miles. On or about XXX, while driving, the vehicle displayed a “Check Engine” warning, “Reduced Engine Power” message, and the Pre-Collision System became disabled. The vehicle immediately became sluggish and lost power during acceleration. The loss of power created a safety concern because the truck was unable to accelerate normally when entering and crossing intersections. I did not feel safe continuing to drive the vehicle, especially while transporting my 9-year-old daughter. Due to the safety risk, I parked the vehicle and have not driven it since the warning first occurred. The warning lights remain active. The vehicle has not yet been inspected by a Toyota dealer because I do not believe it is safe to drive to the dealership. I am requesting dealer evaluation and towing assistance. The component that failed is currently unknown. The vehicle is displaying a check engine light and reduced engine power condition. The condition can be inspected and diagnosed by Toyota. No crash, injury, or property damage occurred because I immediately stopped using the vehicle once the safety concern became apparent. I am submitting this complaint because a sudden reduction in engine power while driving creates a significant traffic safety hazard.

Between the hours of 11:00 a.m. and 1:00 p.m. while heading west with cruise control on and I passed a truck that was fully in the left turn lane my vehicle has done a collision avoidance complete stop three time in the same day. I wasn’t tailgating and I was doing the speed limit of 55 mph. The road was very straight. It did this twice before about a year ago. I reported it to the dealer and they could find nothing wrong with my vehicle.

[XXX], [XXX] PM. 2024 Toyota Tundra Hybrid (i-FORCE MAX, V35A engine), 36k miles, original owner. Clear, dry pavement, evening daylight. Exiting [XXX] westbound at [XXX] , I merged into the far right lane at the second light for a right turn. A vehicle was stopped ahead at the light. Traveling 15-20 mph, I applied the brake for controlled deceleration. Right foot squarely on brake, not touching accelerator. Vehicle did not decelerate as expected. For 3-4 seconds the brake felt unresponsive — pedal felt soft and loose, lacking normal firmness. I pressed the brake fully to the floor. A dashboard warning appeared: “gas and brake pedals are being pressed simultaneously.” I was not, and had not been, touching the accelerator. I then heard engine RPM increase audibly, consistent with an acceleration command, while my foot remained fully on the brake. I felt forward thrust working against my braking. The warning cleared and brakes engaged. Vehicle stopped approximately half a car length from the vehicle ahead, narrowly avoiding rear-end collision. Automatic Emergency Braking did NOT engage despite conditions clearly meeting its criteria — stationary vehicle directly ahead, my vehicle approaching at 15-20 mph with no observable deceleration for 3-4 seconds. No collision warning sounded; no auto-braking intervened. Notably, this same AEB has previously engaged falsely in benign situations (e.g., backing near low vegetation), suggesting reliability/calibration issues. Prior manufacturer notice: On [XXX] at 15,412 miles, I reported to Camelback Toyota, Phoenix (RO #[XXX], on file): “vehicle lurches forward going from reverse to drive (now more consistent)” — dispositioned by tech 10210 as “vehicle is operating to spec,” no diagnosis performed. Same RO documented “rattling in neutral/at stop” — dispositioned “unable to duplicate.” Toyota was on notice of throttle-response symptoms 21 months before this safety event.

While driving approximately 10–15 mph approaching a green light, a truck in front of me suddenly slammed on its brakes. As soon as I saw the brake lights I immediately applied my brakes before any system alert activated. I stopped within approximately 3–5 feet of the vehicle in front of me. At the same time, a truck behind me was approaching quickly. To avoid being rear-ended I pressed the accelerator to move out of the way. However my vehicle would not respond. Despite pressing the gas pedal the truck remained in a braking or non-responsive state and would not accelerate. I attempted to switch between the brake and gas pedal but the vehicle still would not move. This condition lasted approximately 30–60 seconds leaving me stopped in active traffic and unable to take evasive action. This created a serious safety hazard as I was at high risk of being rear-ended due to the vehicle’s failure to respond to acceleration input. The delay was critical and could have resulted in a collision. There were no warning lights or messages prior to or during the incident. The issue occurred suddenly without any indication. This appears to be related to the Pre-Collision System (PCS) and/or the vehicle’s throttle/acceleration system. The vehicle is available for inspection upon request. The issue has not yet been reproduced or confirmed by a dealer or service center and the vehicle has not yet been inspected by the manufacturer or other parties BUT I did call yesterday and haven’t received a response so I will be taking it to Gulf Coast Toyota today [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
