2018 Lexus Ls

At 55,310 miles the car stalled without warning while driving at low speed. The car was towed to a Lexus dealership and it was reported by the dealer after inspection that the engine had seized. The vehicle is available for inspection. The motor failed while driving the vehicle. The V35A-FTS engine has numerous reports of main bearing failure and is subject to a recall for other models that have this engine, however, the Lexus LS500 model is not included in the recall despite having the same/similar catastrophic engine failure with low miles. Lexus corporate has been notified and has contacted the dealer directly regarding the failure. There were no warning lights, no engine sounds, and no indications that there were any issues with the engine.

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 NHTSA 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.
