2020 Lexus Nx

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 NHTSA to consider this issue seriously and take action at your earliest convenience. Thanks

My car is going into limp mode/ reduced power and I am having misfires on cylinders 3 and 4. I’ve replaced my fuel injectors, spark plugs and catalytic converter. Everything down to the electrical has checked out good. The last issue is the fuel pump. My mechanic says there is not enough fuel going to the injectors . I have a faulty fuel pump.

My wife and me and my two kids we all in the car . When we driver this car from highway to local my speedometer keep on 30mph we try to up to 40mph or more.but it doesn’t working. We scared because my vehicle doesn’t show any light on tell us you need fix car . It just happened. So we call Lexus make appointment see what’s going on they told me fuel pump problem we need change. We google saw Lexus a lot car recall beacuse this issue. So we so mad . we bought a lot car they never have this problem. It was so danger . If you car not any light on it show you carnot any problem you can driver but it was so danger. I know Lexus recall a lot this problem car we got similar problem they don’t know fix my car .they don’t care about us safety. They just care about money sell to you car that’s over .

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.

Two (2) times (6-weeks apart) while on Freeway, loss of power and some shaking occurred, making it difficult to bring vehicle to a safe stop. Vehicle has only 80k miles, low for a Lexus brand. Other cars moving at freeway speeds made it more dangerous to stop vehicle safely without getting hit. Failure in both circumstances was related to fuel injectors, cylinder no. 4 at first then second failure six weeks later was on cylinder no. 2, the fuel pump appears to be a known problem on these cars and many Toyota/Lexus models. Low fuel pressure is stressing the injectors to the point of ultimate failure. My wife and kids nearly crashed on the freeway on the first incident, the vehicle with reduced power makes it difficult to control at freeway speeds. Vehicle is well maintained, no warnings were evident, immediate failure occurred. Dealer where vehicle was purchased indicated no alerts/bulletins were evident, repair shop (not dealer) also indicated no bulletins were evident on the first incident. Second failure, another local Lexus dealer indicated no alerts/bulletins where evident of any problems associated with the failure. When escalating issue to OEM/LEXUS Brand Engagement Center, they were able to confirm (they were able to read the failure code when the repair shop connected to the vehicle) the failure mode symptoms was associated with a fuel pump alert. Why both Lexus dealers did not know this is odd. My vehicle has been at the dealer now for over 30 days with no feedback from Lexus on the repair. This failure condition at freeway speeds is a "Safety" risks, Lexus should take this seriously, the fuel pump and weakened injectors should be recalled before someone gets hurt. Please help NHTSA!
