The front of the car under the hood exploded while parked and turned off.

Low pressure fuel pump defective, which caused vehicle to stall while driving. Barely made it off of the highway when this happened, which left me in traffic with children in the car and my hazard lights until able to pull over safely and call a tow. Problem has been confirmed by independent service center and called dealership and they confirmed my vehicle was not apart of the recall. There were no warnings prior to the car malfunctioning.

I have been noticing sluggish acceleration since the end of 2024, specially when fuel falls below or equal to half tank, I took my vehicle to the dealership several times and specifically instructed them to inspect my acceleration issue but every time said no issue on fuel pump. They even failed to reproduce my problem even though I paid for diagnostic. I would like to earnestly request the federal safety agency to consider this issue seriously and take action at your earliest convenience. Thanks

My 2020 Lexus NX 300 caught fire overnight while parked and unattended outside my residence. I discovered the fire the next morning. The Seattle Fire Department responded (incident #SFD-26-0112715) and their report states the fire originated in the engine compartment, with the cause of ignition listed as 'failure of equipment or heat source.' There was no collision, no theft, and no visible external damage prior to the fire. I am the original and only owner of this vehicle, with approximately 48,000 miles, and 100% of scheduled maintenance was performed at an authorized Lexus dealership (Lexus of Bellevue), with no aftermarket modifications. The fire also caused heat damage to a neighboring parked vehicle. I have reported this incident to Lexus Corporate Customer Experience and am seeking further investigation into the cause.

While driving, my vehicle's check engine light came on and the vehicle entered limp mode without warning. It would not exceed 25 MPH and was stuck in 2WD, displaying the message "reduced engine power – take vehicle to nearest dealer." This created a serious safety hazard, as the vehicle could not maintain safe speed in traffic. The vehicle had to be towed to the dealership. The Lexus dealer diagnosed trouble codes P219C00, P160500, P030027, and P0301300 — cylinder #1 air/fuel ratio imbalance, rough idling, random misfire, and cylinder #1 misfire. Through active injector testing, the technician confirmed the cylinder #1 direct (high-pressure) fuel injector has failed, and recommended replacing all four direct injectors at a quoted cost of approximately $6,600. The dealer's inspection report also cited Lexus service bulletin L-SB-0007-21 for possible worn exhaust valve guides, a separate documented defect in this engine that produces these same misfire codes and limp mode, with a repair (cylinder head and valve replacement) that can exceed $10,000. Lexus has known about these failures in the 8AR-FTS engine since at least March 2021, when it issued L-SB-0007-21 covering 2018–2021 NX 300 vehicles. The bulletin acknowledges affected vehicles enter limp mode. Despite this, Lexus has not issued a recall, and owners whose vehicles fail shortly after the warranty period expires are left paying thousands of dollars for a known defect. My warranty coverage lapsed shortly before this failure occurred, and Lexus corporate declined meaningful assistance. A vehicle that suddenly cannot exceed 25 MPH on public roads is a crash risk to its occupants and surrounding traffic. I am requesting the federal safety agency investigate this defect for a potential recall.

The contact owns a 2020 Lexus NX300. The contact stated that while operating the vehicle, the check engine warning light remained illuminated. The message “Electronic Fuel System Failure” was displayed, and the vehicle stalled on several occasions.

The vehicle was later taken to the local dealer, who diagnosed that the fuel pump needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure and informed the contact that the vehicle was not included in an extended warranty coverage associated with the failure. The failure mileage was 88,000.

No warning. I had four high school wrestlers in my car and we had just gotten off the highway after driving for 7 hours from Panama City to Port St. Lucie when it happened. My car went into limp mode making it dangerous to continue to drive. My car is currently at the service center at Lexus of Treasure Coast off US1. The technicians have verified that l have a faulty fuel pump and mentioned the recall but stated my year was not included. With my vehicle being a 2020 I feel as though there is a high likelihood that my fuel pump and others are the same as what has been used on previous years that is not being recalled. I would appreciate you reviewing this matter as it seems enough of a coincidence that I could be right.

While driving at interstate highway speed at approximately 70 mph in heavy rush hour traffic, the vehicle suddenly made a popping sound and immediately lost all engine power. The accelerator became unresponsive, and the vehicle rapidly decelerated without warning. I was forced to coast across lanes to the shoulder to avoid a collision. The engine shut down completely and the vehicle would not restart. This created a serious risk of injury or death due to loss of power in high-speed traffic. The vehicle had to be towed and is currently undrivable. Prior to this incident, the vehicle had a long history of repeated engine misfires. Spark plugs were replaced twice, and a fuel line repair was performed. Despite these repairs, the misfires continued. The sudden engine shutdown occurred without warning.
