NHTSA Complaint #11711785 — 2022 LEXUS GX

While driving my 2022 Lexus GX460, I experienced a sudden and unexpected loss of braking capability while stopped. After bringing the vehicle to a complete stop, the brake pedal pressure gradually decreased while my foot remained firmly on the brake. As pressure lessened, I applied additional force, but the brake pedal continued to travel downward until it reached the floor. At that point, the vehicle began to move forward at idle despite the brake pedal being fully depressed. I rolled towards the intersection (at a stop light). I took my foot off the brake and applied again. It stopped, and then this repeated. I then put the car in park while I waited for the light to turn green. My destination was only 1km away. When I got there, I turned off the car, and have since been unable to replicate the issue. I took it to a dealership (Lexus on the Park) and they charged me for an investigation and told me the car is good to drive. I need Toyota/Lexus to be informed. Note that I am in Canada but a friend advised for me to submit here. I posted my issue on a Lexus forum and a person named Patrick said he had the same issue in September and was told by the dealership everything is fine. I've asked him to submit to NHTSA as well. His VIN is [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
