Purchased a used 2008 Lexus LS460 and within about two hours the vehicle abruptly and completely shut down while driving in traffic, with no warning and no practical ability to predict the failure or safely pull off the road. Near collisions were narrowly avoided only because other drivers swerved or slammed on brakes. At the time of purchase there were no warning lights illuminated, but immediately after the shutdown multiple warning lights illuminated (including brake/ABS/stability-related warnings as documented by an independent service center). The vehicle was inspected the next day by an independent service center, which documented multiple diagnostic trouble codes across major systems and stated that repairs would be in the thousands and not recommended. The inspection also noted indications consistent with diagnostic codes having been cleared prior to purchase, and the battery at inspection could not hold a charge aiding the clearing of codes. The vehicle had no functional exhaust system (mufflers cut off), creating a carbon monoxide exposure risk that was only mitigated because the driver had the windows down unknowingly to the leak. The service center also reported tires beyond safe wear limits that were not readily visible without lifting the vehicle. The vehicle is available for inspection upon request and has not yet been inspected by the manufacturer, police, or insurance.

VIN: [XXX] Current Mileage: 70,440 Vehicle: 2018 Lexus LS500 In November 2021, I purchased this vehicle with approximately 19,000 miles. Routine maintenance was performed every 7,500 miles. At approximately 44,000 miles (in 2023), the vehicle experienced severe engine failure following warning lights for Parking Support Brake Malfunction, Secondary Collision Brake System Malfunction, Check Engine, Reduced Engine Power, and Traction Control Off. The vehicle lost power and stalled. The engine began emitting smoke and was replaced under manufacturer warranty in March 2024 at a Lexus dealership. The repair exceeded $50,000 and included a new engine block and related components. Shortly after receiving the vehicle back, additional major failures occurred: Fuel pump failure resulting in “Reduced Engine Power” and restricted speed (~20 mph). The pump was replaced under warranty (approx. $4,600 cost). Brake system failure occurring three days after that repair (January 2024). As of October 28, 2025, the vehicle has again failed and is currently at Christian Brothers Automotive with the following findings: “Fuel pressure sensor located under the intake manifold is actively leaking fuel when the engine is running. This creates a fire hazard and can affect engine performance and fuel pressure regulation. Immediate attention required.” This repeated pattern of engine and fuel-system failures within a short period after a full engine replacement raises serious concerns about component reliability, workmanship, and safety. Fuel leakage near the intake manifold poses a significant fire risk. There are currently no open recalls addressing this defect. I request that the federal safety agency investigate potential defects or systemic issues in the engine or fuel-delivery systems of the 2018 Lexus LS500, as these failures appear premature, hazardous, and recurrent despite dealer and manufacturer repairs.

2004 lexus ls430 vehicle stalled and would not restart immediately on the road presenting dangerous condition. Engine would crank but not restart. Vehicle would restart the next day. This happened twice before pump failed completely. Research indicates this problem identical to that identified in the federal safety agency campaign id o4v295000.build dates 2003-07-29 until 2004-01-23. Lexus campaign 4lb 2004 ls 430. This vehicle has 44,000 miles on it and has no previous engine repair history defect summary: on certain passenger vehicles, the impeller inside the fuel pump may have been improperly molded due to a manufacturing error. Alcohol in some fuels may deform the impeller and cause it to come into contact with the pump housing. Consequence summary: this condition could increase the rotational resistance of the impeller and, in the worst case, may result in failure of the fuel pump. Owner replaced original failed fuel pump with pump supplied by lexus dealer.

Vehicle hesitates while driving. Recall announced to us 1/20/2020. Have attempted numerous times to have dealership do the free recall repair. Even while there for oil changes and regular services throughout this year. Have been told each time they need to order the part and they will call me. 10 months of this now and car is unsafe- they keep stalling on doing the repair that is a safety risk for myself and family. Want this documented if something happens to us and we have an injury or death because the car has been hesitating and they continue to tell us they don't have the fuel pump to do the repair.

When driving, slowing to make a turn, putting foot back on gas....feels either like gear slipping or fuel injection slip. Makes quick catch and jumps. Also, when coming to stop, feels like stalling. Very scary.
