What 19 owners told NHTSA about the 2018 Lexus Nx300h

My 2018 Lexus NX300 F Sport, stalled while driving, pulled over to safe location turned off vehicle, restarted and proceeded to drive a little. Warning came up on display " Engine power reduced, go to dealer". I was able to drive the car home since it was only 2 miles away. Looked up issue on internet and noticed a recall for said problem. Said do not drive, car is in "limp" mode. Had my car towed to MacIntosh Imports (they only service Lexus & Toyota) they checked diagnostics and code DTC P125D71 Fuel Control Valve stuck. The defect could lead to engine stalling, increasing the risk of crash. Affected vehicles were equipped with a fuel pump that may fail. My vin is not listed on recall, I feel it should be included since the symptoms match and asking Lexus to check for Customer Support Program coverage to fix in "good faith"

I own a 2018 Lexus NX F Sport and have had repeated fuel pump failures since purchasing the vehicle in October 2022. We have replaced the fuel pump twice — once at the dealership where we bought it and again less than a year ago. Despite these repairs, the same issue continues to occur. There were no warning lights before the failure, but once it happens, the check engine light turns on, the traction control light comes on, and the vehicle goes into limp mode. When this happens, the car will not accelerate when pressing the gas pedal. It slows down rapidly and eventually stalls completely. This has happened multiple times, including once in the middle of Dallas traffic and another time while driving to Midland, TX. Each time, my children were in the car with me, putting all of us at serious risk. I have read about the Lexus fuel pump recall affecting similar models and years, and my vehicle is showing the exact same symptoms, yet my VIN is not included in that recall. I believe my vehicle should be reviewed for inclusion in the existing Lexus fuel pump recall, as this ongoing defect poses a major safety hazard to me and others on the road. Recall number: 20LA01 for Lexus (low-pressure fuel pump) — for certain 2018–2019 Nexuses and other Lexus models. Description: “Low-pressure fuel pump inside the fuel tank may fail. If it fails, warning lights and messages may display and the engine may stall while driving.” Additional support: 23LE01 (a Customer Support Program, not a direct recall) covers certain model years with low-pressure fuel pump defects, repairing under this program until July 15 2036 or 150 k miles. I believe my vehicle may fall under recall 20LA01 (Lexus low-pressure fuel pump) or the subsequent support program 23LE01, because the symptoms and repeated fuel pump failures match exactly, yet my VIN returns no open recall. My car currently has 144,400 miles on it. I’d like to get it fixed as swiftly as possible. Diagnostic tests are too costly.

In June 2022, the vehicle exhibited abnormal engine behavior, specifically fluctuating revolutions per minute (RPM), while at a complete stop, creating a risk of engine stall. Newport Beach Lexus dealership opted to replace the fuel injectors and gaskets as a corrective measure. Previous invoices also show that there were concerns related to fuel equipment prior to this incident. Subsequently, in December 2024, while traveling with my child on [XXX] near Barstow, California, the vehicle experienced severe shaking during an ascent, leading to a temporary loss of power while driving. I continued to drive after a brief respite due to the unsafe, remote location in the desert. Upon arrival in Las Vegas, the vehicle was inspected by a Lexus dealership, and they were unable to identify the issue at that time. In January 2025, the vehicle’s check engine light came on and further inspections at Lexus South County revealed that the vehicle was unsafe to operate without replacing the fuel pump. The dealership indicated that the vehicle would not be released unless this repair was completed and the fuel pump was replaced. The National Highway Traffic Safety Administration (NHTSA) identified a safety recall (NHTSA Campaign ID 20V682000) for these vehicles due to a defect in the low-pressure fuel pump. The defect could lead to engine stalling, increasing the risk of a crash. Affected vehicles were equipped with a fuel pump that may fail, causing the engine to stall while driving. Toyota and Lexus dealers were instructed to replace the fuel pump assembly with an improved one at no cost to the vehicle owner. These events suggest a potential failure to adequately address a known safety defect, leading to compromised vehicle performance and increased risk to occupants. Failure to add this vehicle to the recall list created an ongoing unsafe situation for my family and also compromised the health of the vehicles’ engine and other parts that rely on the fuel pump.

While driving regularly on the highway my sunroof spontaneously shattered. There were no warning signs and no visible debris on the road that could have hit it. This is the SECOND instance of this happening with this vehicle (2018 Lexus NX 300) within three years. The sudden loud sound is dangerous as it can cause someone to jerk the steering wheel. Also, if the sunroof is open, glass could rain down on the occupants of the vehicle. My sunroof was closed at the time, but my vehicle littered glass over the roadway while trying to exit safely. The dealership refuses to take responsibility for the manufacturing defects in their sunroofs.

Advisor Jamie message me saying Tech had basically check the vehicle, system pressurized as it should be so if there were leaks they would be visible, basically Tech wasn't getting no read to the problem. I suggest to have him test drive and she said he Tech would drive vehicle and get back. I researched recalls with my vehicle and saw Fuel Pump customer support program for failing fuel pumps recall as with my Lexus 300NX. I told Advisor about the recall and sent her the recall notice online. Advisor looked into the fuel pump recall in our telephone conversation, confirmed the fuel pump was recall n would be replaced. I told her i saw where the failing fuel pump with my Lexus online described what my vehicle was doing. Advisor now said car coolant fans/etc needed to be replace, I didn't understand this when I didn't have a cooling problem before coming there. Advisor tried to pressure me into the coolant fans/ module issues before doing my failing fuel pump, suddenly. I felt they were now lying about fans . I told her i would be in the next day, get a loaner. Next day, i was team up on at lexus by 3 Reps minus the Advisor who was there. Denied me the free fuel pump replacement, pressure to let them fix fans/module 1st , I refused, felt deception practice.

I was driving on 64 and at a sudden my 2018 NX 300 stopped accelerating and engine was stalled. I was lucky that the highway was not busy, so I was able to park it on the shoulder of HWY and later towed it to my home. The car was not drivable anymore as engine was keep shutting down with the warning and engine lights. The code on the screen was P0087 - Fuel Rail/System Pressure - Too Low. It seems that the fuel pump mall function. I research online and noticed, that others also reported the same issue related to Fuel pump failure on this model. Also, on further research, I found that Lexus recalled this model along with other models for the same issue. But when I check my VIN then it shows that my VIN has no recall related to Fuel Pump mall function. Not sure why my VIN is not included in the recall even though this model and year has a recall for this issue.

After 45 minutes in stop-and-go traffic the brake pedal went to the floor four times, the Brake Override System (BOS) failed, throwing the shifter into Park failed, and we hit the car in front of us. No warning sounds typical for this car sounded and no lights appeared on the dash. Thankfully, we were only moving at 5 mph which I didn't think qualified as a "crash" but there was indeed a collision. No one was hurt. Besides my wife and myself there were two backseat passengers who also saw my efforts to stop the car. We had the car towed to Lexus of Santa Monica. Unsurprisingly, Ronald Inton with Toyota Motor North America, Inc. (TMNA) indicated in his letter to us that Lexus inspectors seeing our crumpled front license plate and knowing of the failure of the BOS found nothing wrong with the car, but had not driven it under stop-and-go conditions for 45 minutes as we had. The clear failure of the BOS to prevent the collision or even warn of the impending collision was effectively ignored my Mr. Inton. Our full correspondence with him is attached. Both my wife and I loved driving this car but it is a potentially deadly safety hazard and given that TMNA can't fix it, should be destroyed.

I HAVE A 2018 LEXUS NX 300H, THAT WE BOUGHT 2 YEARS AGO AND HAD BEEN BRINGING TO THE DEALERSHIP FOR MAINTENANCE. RECENTLY ON AUGUST 31ST, 2020 MY RIGHT PASSENGER MIRROR EXPLODED WITH WIRES HANGING OUT AND MIRROR POPPED OUT- LUCKILY I WAS A BLOCK AWAY FROM MY HOUSE RUNNING ABOUT 5MPH, OR MY MIRROR WOULD HAVE FLOWN IN THE FREEWAY AND MAY HAVE CAUSE AN ACCIDENT. BROUGHT TO THE DEALERSHIP BUT THEY SAID THAT I MIGHT HAVE HIT SOMETHING SINCE THERE WAS THIS THREAD LIKE DENT- (WHICH THEY SAID COULD HAVE HAPPEN DUE TO THE MIRROR POPPING OUT OF ITS CASE.) STILL DOES NOT MAKE SENSE TO HAVE A SIDE MIRROR EXPLODING. ITS LIKE IF YOUR CAR GETS EVEN THE TINIEST DENT YOUR MIRROR MIGHT EXPLODE. THE DEALERSHIP CLAIMS THIS IS NOT COVERED BY MY WARRANTY DUE TO WHAT THEY CLAIM SOMETHING FLEW OR HIT THE SIDE MIRROR. I KEEP ON TELLING THEM - I WAS THE DRIVER NOTHING HIT THE VEHICLE. HOPEFULLY THIS MANUFACTURER TAKE THIS SERIOUSLY BEFORE ANY ACCIDENT HAPPENS.
