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 workin
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 acce
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!
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 t
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
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 n
The hill assist does not work as should which causes the vehicle to drift backwards and engage the traction control/ brake system which hinders your ability from moving forwards. This is dangerous for many reasons such as drifting backwards into the vehicle behind you, if it’s icy it could cause the vehicle to break loose and go backwards uncontrollably, and cause unwanted delay in pulling out which has occurred multiple times. The local Lexus dealer said this has been occurring in these vehicles for a long time but indicated nothing is wrong. This is unacceptable because this has almost r
