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.
