The contact owns a 2023 Lexus LX 600. The contact stated that the rearview back up camera image displayed a distorted image.

Purchase Date of LX600: 10/26/2023 Date of Incident: 12/21/2025 While driving home (at about 65 MPH) the vehicle gave an alert on the dash which said Pull Over - Vehicle Losing Power and Shutting Down. Once this alert appeared on the dash, we had approximately 30 seconds to find a safe spot to pull over. The road that this happened on is a one lane road in each direction in a rural zone that is highly traveled by Semi Trucks. Luckily, there was a gravel spot on the road where we were able to stop the vehicle, just in time to avoid a catastrophe. On 12/22 we took vehicle to Lexus of Wesley

I am writing to report a concern regarding an unresolved safety recall for my 2023 Lexus LX 600. Lexus notified us of this recall on November 6, 2025. However, nearly four months later, the company continues to state on its website that no remedy is currently available. Given the significant purchase price of this vehicle—exceeding $100,000—I find it unacceptable that a resolution has not yet been provided. I respectfully request that this matter be reviewed and that appropriate action be taken to ensure a timely and effective remedy for affected customers.

02/20/20Component: ENGINE

I am filing this complaint regarding the handling of Safety Recall 25LA07 (NHTSA Recall ID 25V767) affecting my 2023 Lexus LX600. On January 2, 2026, I delivered the vehicle to the authorized Lexus dealer in Ponce, Puerto Rico, in response to the recall, which identifies potential engine knocking, rough running, engine no-start, and/or loss of motive power. These conditions represent serious safety risks. Since that date, the vehicle has remained at the dealership. More than five weeks have passed, and neither the dealer nor Lexus has provided a definitive remedy, technical instructions, or

02/12/20Component: ENGINE,FUEL/PROPULSION SYSTEM

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 sp

01/12/20Component: ENGINE AND ENGINE COOLING

The contact owns a 2023 Lexus LX 600. The contact received notification of NHTSA Campaign Number: 25V767000 (Engine and Engine Cooling). The contact called the dealer and the manufacturer and was informed that the remedy was not yet available. The contact stated that the dealer and the manufacturer offered a stipend for a rental. The contact deferred on renting a vehicle. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact had not experienced a failure.

04/29/20Component: ENGINE

My car suffered complete engine failure at 25,522 miles. Lexus claims that it is not in the VIN range of the recall. However, it is the exact same problem all other 2022-2023 LX600 are experiencing and being recalled for. Lexus is clearly minimizing the extent of the engine failure issue and my VIN is also part of the problem.

04/24/20Component: ENGINE,FUEL/PROPULSION SYSTEM

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.
