2022 Lexus GX Brakes Problems

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)

Notice brakes would not hold vehicle and begin to drift into intersection. Depress brake pedal more and it would stop then start to drift again, then placed into neutral as the brake pedal was almost to the floor. So as you were at a red light the brake pedal never moved but wasn't applying constant pressure to keep vehicle stationary then I'd have to apply more brake pedal and repeat. Ma aged to get to work safely and had it towed to Rohrick Lexus and they kept it for two day having a mech take it home. They could not duplicate!

I was traveling east bound on 161/16/37 near Raccoon Valley Golf Course in Granville OH. I was near MM 104. It was approximately 8:13PM and the road conditions were clear. No other vehicles were in front of or behind me. I heard a screech, the wheel jerked out of my hand to the left, and the wipers came on. I tried to regain control and keep the vehicle on the road. The wheel kept tugging to the left and I was fighting to pull it right. At the same time, I was also pressing on the brake, but it went straight to the floor. I kept pumping on the breaks because I didn’t know if the ABS was working. Then I hit the guard rail on the right side of my car and after I hit the guard rail, that time when I pressed the breaks, I was finally able to stop. I am unsure what system malfunctioned. There were no lights or warning messages. I did have the vehicle at Lexus for routine maintenance a couple weeks prior. The sheriff came to the scene and filled report 23-31830. I also called Lexus the next day and filled a request for an inspection to be completed. My insurance company is aware, but has advised I don’t file the claim until after the investigation is complete.

Parking brake foot pedal on my GX460 has a very sharp edge on the metal piece on the back side of it. In disengaged position, it sits directly above the left footrest position. If I slight lift my left feet or stretch the foot on a drive, it hits the back side of the parking brake. Around late-Nov '23, the boot that I was wearing on a drive had a cut on it. Upon closer inspection I found a very sharp knife-life edge at the back of the parking brake foot pedal which caused this cut. I took it to the Lexus dealer (Lexus Naperville, IL) where I'd purchased this car in Aug '22. They looked it at it & agreed sharp edge. However, they mentioned that it is from Lexus design & they can't do anything, especially this being on a safety device like brakes. They did refer me to Lexus directly. After multiple email & phone conversations, the Lexus team came back to me saying that it is normal to have a sharp edge like this & failed to acknowledge this being the safety risk. I'm flabbergasted as it's a danger if I or my wife were to wear an open sandal when driving. The sharp edge will cut through the skin & the reflex of being in pain while driving will pose danger both to my family in the car & others on the street. Picture attachments: 1. Two pictures showing the location of the sharp edge behind the parking brake 2. Picture of the boot which was cut due to this sharp edge. I've a copy of the assessment done by the inspecting dealer, Lexus Naperville. As any documents with personal details can’t be shared here, I’m not doing so. I’ll glad to share that if & when needed. It is unfortunate that Lexus is not acting on this dangerous situation with my car. It would be much appreciated if you can investigate & intervene to get this fixed for the safety of both my family & others on the road, Thank you.
