2021 Lexus NX 300h Service and Repair Manual

Vehicle began exhibiting multiple electrical safety issues around April 2025. EMF (electromagnetic field) levels were measured and found to be excessively high, causing physical discomfort and triggering health concerns for my disabled son and me. We both sought medical attention. Two independent mechanics inspected the vehicle and confirmed it showed signs of water intrusion or exposure to hazardous materials — including corrosion, damage to internal components, and abnormal underbody residue. I reported this to Lexus in April and also submitted a lemon claim, but they have failed to act or r

Coming down a steep, narrow, long driveway leading from a private home on a hill, and moving forward in low gear, I allege that the brakes failed. After 3-5 attempts at braking, we came off the cement driveway as we accelerated and slid off the side of the hill, turning over onto the driver's side of the car and coming to rest near a dropoff, held by the branches of an oak tree. Fire engines came, and the Jaws of Life were applied, basically demolishing the car (which did hold together as we slid along). The seat belts also did their job. The car was removed from the towing yard in Grover

While driving our Lexus on 8/13/2023 on the interstate under normal driving conditions ALL of our warning lights came on one after another. We also lost air conditioning and power brakes it seemed. We immediately exited and pulled over. Opened the hood and the engine caught fire and fully engulfed the engine compartment. From the time of the first warning light to the vehicle being engulfed was probably 5 - 7 minutes. The vehicle was deemed a total loss. We filed a product liability claim with Lexus/Toyota and they investigated the vehicle on or around 8/28/2023 and were not able to dete

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The high-pressure fuel pump and related fuel system sensor failed, resulting in a sudden loss of engine power. The failure was confirmed by diagnostic trouble codes retrieved by an independent mechanic. The vehicle is available for inspection upon request. 2. How was your safety or the safety of others put at risk? While driving at highway speeds, the vehicle suddenly lost power and became inoperable, leaving me unable to accelerate or maintain speed. This created a dangerous situation with

My vehicle has slowed while driving four times within the last 12 months. I have taken it to the Hendrick Lexus dealership in Charlotte as well as the Scott Clark Toyota dealership in Charlotte. I was told by the Lexus dealership they could not find anything wrong (this was back in July 2025). The Toyota dealership stated (March 2026) that there may be a problem with the fuel pump, but they were unable to confirm this issue and after getting the vehicle back the same thing happened while driving. This has been concerning. It is very dangerous for us to drive the vehicle at this point. I see th

The contact owns a 2021 Lexus NX300. The contact stated that while driving at various speeds, the vehicle slowly lost automotive power and decelerated. The contact pulled over to the shoulder of the roadway and restarted the vehicle to continue driving normally. The contact stated that the check engine, traction control, and Service Soon warning lights remained illuminated. The vehicle was taken to a local dealer where the vehicle was diagnosed, and the contact was informed that the fuel pump was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of t

The passenger airbag light is constantly on. When no one is sitting on the chair, the light states that the air bag is off and when someone is sitting in the chair, the airbag light states that it is on. I just purchased this used car a month ago from a Toyota dealership. Two weeks in with no accident whatsoever, the problem had occurred. I noticed the airbag light turned on when I first purchased the car but it would quickly turned off completely after a while.

The contact owns a 2021 Lexus NX300. The contact stated that while the vehicle was parked, his father heard the car alarm sounding off. The contact went to inspect the vehicle and saw that sunroof glass had shattered. The contact stated that he reviewed the home security footage and observed that the sunroof glass had not been impacted by an object for the sunroof glass to shatter. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 37,718.
