2019 Toyota Tundra: false forward collision warnings

Filed Sep 29, 2026 · Driver assistance · AR

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."

The electrical system malfunctioned, causing all warning lamps on the dashboard to light up. Because this happened while I was driving, I do believe that this electrical issue caused safety concerns for others on the road. The taillights went out first, seconds later, all remaining electrical failed at once, including airbags, windows, headlights at one point, pre collision warning lights, lane departure, and the breaking system failed as well. This caused safety concerns for myself, my passenger, as well as the public because all safety warning sensors failed at once while on the road. The problem has been confirmed by Roseville Toyota, who is a manufacturer, and who currently has the vehicle now, they said that there is definitely an electrical issue and most likely a short of some sort. The warning lamps and messages on the dash lit up one at a time, seconds apart from each other, until the entire dash was lit up completely while I was driving on March 24, 2023.

2019 Tundra: for no reason or indication the vehicle displayed a “Trailer Break Error” and “Pre-collision System malfunction” warning asking me to pull over if towing anything (nothing was being towed) and to contact the dealership. Vehicle still operational however the menus can’t be seen as the warning is consistent.

Toyota Safety Sense (TSS) malfunctions sporadically while driving. Warning lights illuminate and Dynamic Radar Cruise Control (DRCC) disengages when activated while driving. The Pre-Collision System (PCS) is turned off and flashes with the following error messages. - Pre-Collision System Malfunction - Visit Your Dealer - Auto Headlight System Malfunction - Visit Your Dealer - LDA Malfunction - Visit Your Dealer This has happened twice, first right after purchasing the vehicle brand new in 2019 and most recently last week on 5/22/2021. I took the vehicle into the dealer on 5/25/2021 and they seemed aware of this issue, but stated they could not reproduce it and there were no error codes logged. I showed them the video of this happening (link below) while driving through Nevada. I was told the errors will not disable the vehicle or put it into limp mode, but my concern is when this happens while using DRCC, which almost made me drive into the back of a tractor trailer on Interstate 80. The speed limit on I-80 in Nevada is 80 MPH. https://drive.google.com/file/d/1WrxgM8SJeB02eO4a6E9tbyCeAr6gRRHs/view?usp=sharing

Less than 3000 miles when incident happened. While driving at 55 MPH on a highway the dash screen said brake and a chime was heard. It was late evening 3 days ago and their was absolutely no other vehicles around me. My initial reaction was to brake however I did not. It also happened two additional times at about 45 MPH on the final few miles from my home. The indicator did not stay on long enough to get a photo of it. When I returned home I filed a case with toyota USA. I then called them the next day. Today I contacted the dealer about taking it in for the to check. At that time the service rep advised me there is a recall on the part sensor on the anti collision avoidance system. I received an email reply from toyota USA however the reply did not provide me with any information , other than the case was going to be entered into their database. They will place a foamy tape on the back of the sensor after running a diagnostic on it. This seems a bit under done and a band aid for what could be a safety hazard. If it is a water issue (no rain on the day it happened and didn't happen on the way to my destination) I researched the VIN for the recall and I received "there is no recall associated with my VIN, answer. Hopefully the federal safety agency will do a simple website search and see the numbers of people having this issue. I prefer not to have any safety issues while transporting my family in the vehicle.

While driving with the adaptive cruise control set a message will appear "radar cruise control unavailable clean sensor". This message will appear with no adverse weather conditions. Due to this error the cruise control no longer works and the pre-collision warning system no longer works. Also randomly a "brake!" message will appear and the vehicle automatically slams on the brakes when no emergency exists creating a hazard for vehicles behind.
