2024 LEXUS NX Complaints

My son and I were almost killed the other day because the engine of my 1 year old car failed. We were in the middle of 6 lanes of rushing highway traffic when the car stopped accelerating and came to a dead stop. I had just had the car serviced 10 days before and didn't feel, hear or see anything hit my car. The message on my dashboard said "go to the dealer" when it should have said "pull over immediately, turn off your car and call for help". The dealership told me that a rock must have gone through the grill and punctured my radiator. They explained that radiators used to be made of copper and now are made of aluminum and are very fragile. They also said that the spaces in the grill should be smaller so it's not so easy for rocks or debris to get to the radiator. I asked if this was a common occurrence and they told me they've seen it 3 times in 2 years just at this one dealership. I feel the design of the grill is a safety hazard and warrants a recall. I'm afraid someone else won't be as lucky as me. We could have easily been killed or caused a massive car pile up on that highway that resulted in many people being injured. It was terrifying. I called manufacturer's customer service department to share this and asked that the error message be changed. They referred me to you regarding the design flaw of the grill.

There’s something wrong in the electrical system. In order to start the car, it requires boosting the battery only. Boosting under the hood doesn’t work with the lithium power packs charged 100%. After signing the financial documents the day I test drove it, I couldn’t drive it home if I wanted to. The car wouldn’t start. I don’t know how the dealer got it started but I have been intermittently boosting it to start. This happens whether the car sits a day or more. The last frequent boost was 3/17/2025. Another thing, the car can be in driver assistance with lane tracking and the lane tracking will shut off automatically. Also, when the lens of the cameras on the car gets wet, the cameras don’t work. They become foggy blank.

7 months after purchasing a Lexus 350h, the driver seat started having noise when it moves. Three steel balls and several pieces of white plastic detected in the rail. Look like a ball bearing, which is part of the power seat, was disintegrated.

My vehicle has a vibration in the steering wheel and floorboard between approximately 38-48 Mph but mostly around 43 mph. It is random in severity and sometimes feels like the vehicle has a flat tire.With this issue it is impossible to determine if the vehicle has a tire out balance, an alignment issue or some other drivtrain component problem. This could cause someone to pull the car over to check the tires and impede traffic, possibly causing an accident. The dealer couldn't detect the vibration. After 4 months an FTS finally detected this vibration on a test drive. He then said it was normal operation characteristic from the hybrid powertrain. I was told all of these vehicles perform this way. I've driven 2 other vehicles, identical to mine, that absolutely do not exhibit any of the vibration and harshness my vehicle does. This is an unacceptable "driving characteristic" of a $52,000 luxury vehicle. There have been no warning lamps or notifications on the instrument panel. This problem has been present since new (December 2023)but took me about 3 months to narrow down what was happening and at what speed. Rough roads can disguise this vibration but can be felt nearly every time the vehicle is driven.

Lexus [XXX] & [XXX] [XXX] [XXX] [XXX] Lexus P.O. Box 259001 Mail Drop E3-2D Plano, TX 75025-9001 To Whom It May Concern, I am writing to express my serious concerns regarding a safety issue we encountered with our 2024 Lexus NX350, purchased from your dealership at 1000 Interstate Parkway, Akron, Ohio, 44312, in August 2023. Our purchasing experience met the high expectations associated with the Lexus brand, and we were pleased with the vehicle's features. During the delivery process, we received a walkthrough of the car's functionalities, and the technician assisted us in connecting her phone to download the app. However, there were no tutorials or instructions provided regarding the safety features, particularly in the event of an emergency except for showing us the SOS button on the at the roof panel On [XXX], my wife, [XXX], was involved in an accident while driving the NX350. I have included a photo to illustrate the extent of the damage. When the police arrived, [XXX] found herself unable to open either the driver or passenger doors; all doors were unresponsive. The officer (Hetrick #426) from the Macedonia, Ohio Police Department was also unable to assist her from the outside because the doors were not functioning from his side, as he could not determine if she was injured. She used the SOS button, which the call center was responsive, however, the could not assist with helping her to make the doors function. Faced with the urgency of the situation, [XXX] had no choice but to climb out through the window, which was extremely difficult for her given her injuries. This incident raises significant safety concerns. When we contacted the dealership to inquire about any known defects, we were told there were none, and the response was defensive, focusing on how we were instructed to manually open the doors during our walkthrough. However, neither of us was shown how INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On Sep 16, 2024 I purchased a 2024 EX450 Plug-in Hybrid. During the purchasing process that new car delivery person recommended using the Lexus app which I installed. From Sep 18 through Sep 23 I drove the car in the EV mode around my community. I put on approximately 15 miles. On the morning of Sep 24, 2024 I needed to go to an important meeting. On Sep 23 in order to prepare for a 40 mile drive I plugged the car in and obtained a full charge. At 6:15am I opened the hatch and packed my car. The rear hatch opened without any issues. At 6:30 am I tried to enter the car and the car was locked. Fortunately I left the hatch open and I was able to crawl through the back of the car and open the car doors. I then tried starting the car and the car would not function, no click, no lights, all electric systems were dead. I reviewed the app on my phone and what was 36 miles 100% charged the previous night now stated 0% charged and -1 miles. Something had discharged the car overnight. There were no lights on or doors left open. The car was transported to the dealer. After a day of testing the battery (which was within spec) and the functions of the car the tech recommended the app that I used to monitor the charge status and other status's of the car including the ability to remote start the car be removed from my iphone. It is thought that the car overly communicates with the app thereby draining the battery. Doing on-line research I learned that others have come to this same conclusion. I am requesting that Toyota Motor Company immediately investigate this issue and if the app is the culprit immediately issue a warning to all its consumers that use the app to immediately remove the Lexus app from their phone. If a person had placed their children in a car seat, activated the hatch and closed the doors the doors would automatically lock. A caregiver could inadvertently lock their child in the car.

The passenger side blind spot monitoring system triggers when no cars are present. This causes the steering wheel to resist switching lanes. These false positives occur every day no matter the road condition or day/night. This is specifically apparent on highway driving above 50 mph

Less than 10 months old (March and April 2024 at ~5,000 miles), the 12V battery completely drained 3 times in 5 days (despite driving it regularly during that period) so the car would not start when needed. I had it jumped 3 times by AAA and the third time drove it to dealer. Dealer told me battery was defective so it needed to be replaced under warranty. Problem reported to Lexus Customer Service. The same problem recurred 3 months later (July 2024 at 6000 miles) the morning I was packing it to leave on vacation. The battery died while I was in the car and I was locked inside. When I got out, the doors locked again so had to have the car towed to a different dealer. They told me the battery needed to be replaced AGAIN under warranty. Two Lexus dealers, Lexus Customer Service, and Lexus on-line forum have noted this problem with several Lexus hybrid and PHEV models for a period of 1-2 years. When I asked, Lexus (2 dealers and Customer Service) told me that there is a defect in the software or app communication settings that causes a continuous drain on the 12V battery causing battery to fail unexpectedly. There has been NO NOTIFICATION of this defect and no resolution to this problem has been provided in the past 5 months. It is a risk for the entire electrical system to fail unexpectedly for no apparent reason with NO WARNING. The car is unreliable and cannot be used if it will not start when it is needed. We are elderly and have grandchildren living with us periodically. We are at risk if we cannot get to medical appointments or drive to the hospital.

The contact owns a 2024 Lexus NX 350H. The contact stated while the vehicle was parked, the passenger’s side side view mirror shattered without impact. The vehicle was taken to a dealer, where the contact was informed that the repair would be paid for out-of-pocket. The manufacturer was made aware of the failure. The failure mileage was approximately 5,500.

There is a defect on all models like mine, and the dealer claims that it cannot be fixed. With my former vehicle, a 2019 BMW 340i GT, whenever I drove into a garage, the headlights would come on immediately so I could easily see where I should go. With the Lexus, it takes about 5-to-8 seconds for the headlights to turn on. This is unsafe to anyone walking in the garage inn that area.
