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. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My car is stalling all the lights are on. I was told that the recall was out for this one.

An interim notice was issued October 15, 2014. Almost six months have passed, and I have not received a notice to have a resolution to this potentially explosive problem.

After an oil change, using fully synthetic oil per sterling mccall Lexus of houston, the Lexus Ls460 shows hesitation in acceleration. At local road and at speed of 15 mph, I tried to accelerate and pushed gas pedal to floor, the engine rpm reached more than 5000 but the car did not accelerate as expected. While in theory the engine power reaches peak of 386 horse power at 4200 rpm. In one word, the acceleration is not linear to the push on gas pedal at all. Feels like the engine power does not corresponds to the gas pedal travel distance, as it should. And in critical situations, this failure to accelerate as it should could cause problem or accidents. A google search shows that many other owners have the same experience. Maybe Lexus should look into this and help fix the problem. Thanks,.
