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.

Intermit message "Trailer disconnect " message causing the trailer braking system to fail when attached to truck. Truck brakes are used to stop trailer at unsafe distances. Several trailers were used to verify. I have attached the fix but Toyota says its warranty issue. This is a "safety" issue. I had my 3 year old son in the truck when i had to apply the brakes and couldn't stop in enough time. The truck brakes could not handle the weight of the trailer hence why the trailer brakes were needed. Please prevent a death.
