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)

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.

This vehicle has had bad engine rumbling since I have Owens’s the vehicle and makes loud noises all the time since I have owned it new. Also this year car online has had known suspension issues and alignment issues. My vehicle pulls to the right all the time and steering wheel is off center. Also my front socks with only 6200 make noise when going over bumps. I have been to the dealership over these issues twice and they tried to fix the alignment the first time since it was out but used the wrong specs bwcucase they are not out for 2022 Lexus gx 460 yet. Also the rumbling the dealership can not figure out at all.

I am reporting two safety-related problems in my 2022 Lexus GX 460, both present since shortly after purchase and the vehicle is available for inspection upon request. 1. Power Train / Speed Control (delayed acceleration / no throttle response): When I transition from the brake pedal to the accelerator pedal quickly (normal driving), the vehicle intermittently displays a warning message indicating the accelerator is being pressed while the brake is also pressed (or similar wording). When this happens, the vehicle does not respond to the accelerator for several seconds even if I press the accelerator to the floor. This has put my safety and the safety of others at risk because the vehicle fails to accelerate when needed (e.g., when merging, turning, or avoiding traffic), creating multiple dangerous near-miss situations. The warning message appears at the time of the event; I did not notice a warning lamp or message consistently prior to the event. This issue has not yet been reproduced or confirmed by a dealer or independent service center. A dealer service visit is scheduled for next week. The vehicle has not yet been inspected by the manufacturer, police, or insurance representatives for this problem. 2. Seats (driver seat causes leg numbness/spasms impairing pedal control): The driver seat bottom is unusually firm, and after approximately 30 minutes of driving my legs become numb from the lower thighs down to my feet and I experience spasms to the point that I cannot safely operate the brake and accelerator pedals. This is a safety risk because it can prevent proper pedal control while driving. This condition has been consistent since shortly after purchase. It has not yet been confirmed by a dealer or independent service center, and the vehicle/seat has not yet been inspected by the manufacturer, police, or insurance representatives for this issue.
