Other Fuel System problem #1

Description of incident: this is a recurring safety defect that has occurred multiple times from August 2023 to February 2026. The following description refers to the most severe incidents: 1. Nature of defect: the vehicle experienced a sudden "limp mode" event where all dashboard warning lights illuminated simultaneously, followed by an immediate loss of propulsion while in motion. Subsequently, the vehicle suffered from a dangerous 3-second acceleration lag/delay. This 2023 Lexus Lx 600 creates a life-threatening risk on public highways, as the driver cannot reliably control the vehicle's speed or power to avoid collisions. 2. Manufacturer’s admission: the vehicle has been presented to authorized Lexus dealerships. While the dealership could not provide a permanent fix, the manufacturer’s own internal tracking system now explicitly confirms: "remedy: not available. " this is a formal admission by Lexus/Toyota that the vehicle has a catastrophic system failure with no known fix. 3. Requested action: Lexus/Toyota has refused to repurchase the vehicle, forcing me to drive a dangerous asset they admit they cannot repair. I request that NHTSA immediately initiate a safety investigation into this loss of propulsion and acceleration lag issue for the 2023 Lexus Lx 600, especially given the "no remedy" status. A mandatory recall is warranted.

Other Fuel System problem #2

My problem occurs intermittenly, it occurs when I am idling at a stop. When I have to accelerate from the stop the car will lurch forward and die for approximately 3 seconds. It will then restart and drive normally, however the stopping in the middle of oncoming traffic is potentially life threatening. It has occurred approx 8 times since I bought the car in June 2023. I had the eco recall done and it also occurred shortly after that. I have taken it back to the dealer and they could not recreate the problem. It occurs after idling and waiting and then accelerating quickly to merge.
