2023 Lexus LX 600 problems

“On October 29, 2026, while driving my 2023 Lexus LX 600 at approximately 30 mph on a local road immediately after exiting a 75 mph highway, the vehicle suffered a sudden, catastrophic loss of motive power. The engine completely seized while in motion, and the RPMs immediately dropped to zero. Multiple warning alarms triggered on the dashboard, displaying a fatal warning stating 'Loss of Power Steering' or 'Power Steering Failure.' Because the engine died, I instantly lost power steering and braking assists, making the SUV extremely difficult to control and pull over. Once stopped, the vehicle completely refused to restart for approximately 10 minutes. This vehicle is part of active safety recall 25V767000 (Engine Machining Debris), for which Lexus has stated 'no remedy is currently available.' Driving this vehicle with an un-remedied manufacturing defect actively put my life at risk. Had this total engine seizure occurred just minutes earlier at highway speeds, it could have caused a multi-vehicle crash.”

“The contact owns a 2023 Lexus LS 600. The contact received notifications of NHTSA Campaign Numbers: 25V767000 (ENGINE AND ENGINE COOLING), 26V18000 (SEATS, AIR BAGS); however, the parts to do the recall repairs were not yet available. The local dealer was contacted and confirmed that parts were not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repairs. The manufacturer was made aware of the issue. The contact had not experienced a failure.”

“I received notice over a year ago that the engine in my Lexus was defective and failure could cause damage, injury or death because the engine would seize up. We drive in rural areas, often outside of cell service. We are [XXX] and to be stranded, especially at night, would be very dangerous. I have made several calls to dealers and Lexus in Plano, and no one is willing to do anything about the problem they have created. They offer nothing.”

“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…”
