ODI #11581900UNKNOWN OR OTHER

I allowed a software update to my vehicle about six weeks ago. Now, about 10 minutes after starting the car, a screen comes up, completely covering all vehicle information. The screen does not close except with repeated tapping of the X and the left bar. Closing the screen requires attention that would be better paid to road conditions and other drivers. I asked my Lexus dealer service department to get rid of the screen. They were unable to do so. They suggested contacting Lexus via the emergency button while parked. I did so but when I replied that I did not have an emergency, I was disconnected. If this screen came up when the vehicle is started, then it would not be a safety concern. But coming up 10 minutes after ignition, it is definitely a dangerous distraction. I live in a mountainous region where driving requires full attention. It is a 30 minute drive to where I can pull over and get rid of the screen. During this time I am distracted by the screen and have no access to vehicle information.

Safety recall was issue in July 2023. NHTSA Recall Number 23V478, Manufacturer Recall Number 23LB01. As of today March 2024, there still no remedy for the recall. I'm not able to use the car because of this safety recall. Over 8 months with no remedy or timeline when it will be fix.

ODI #11557308UNKNOWN OR OTHER

Hello, I'm currently in Ontario, Canada, and I've been experiencing an issue with my car. Specifically, the driver's door refuses to open when the temperature drops below freezing. This problem is consistently occurring, making it quite inconvenient as I'm unable to access the driver's side. It appears that the sensor freezes in such conditions, preventing the door from opening externally. Its been 5 days the temperature is below freezing and my driver side door will not open from outside door handle. Fortunately, it does open from the inside. This situation becomes particularly hazardous during strong winds when I have to open the door from the passenger side, risking the door swinging open unexpectedly. This could potentially lead to fatal consequences if the door collides with a passing vehicle or motorcycle. This issue is recorded by multiple dealers, its reported on Lexus forums and i have escalated it to Lexus of London. Canada. And Lexus USA too.

ODI #11554781ELECTRICAL SYSTEM

The electrical system failed. It operates just about all the systems including items that are normally operated manually. My wife entered the car and pressed the start button and the car would not start. The car locked my wife inside with no manual method for opening the door. Fortunately, I was home at the time and was able to execute a manual release of the door using a key found inside the remote. Lexus sent a AAA service truck to jump start the engine. We believe this dangerous situation is related to our previous complaint #11495096 for VIN [XXX] on 11/28/2022 where the car locked us out on two reported occasions. At vehiclehistory.com I found a similar problem reported for the Lexus RX450h, another plug-in Hybrid. In that case an amp meter was used to trace the source of the electrical drain from the battery. A faulty amplifier was consuming more power than needed and draining the 12 volt battery to a completely discharged state. There is a problem with the auxiliary battery holding a charge. There were no warnings, messages or prior symptoms. The car is available for inspection on request. We are taking it to the dealer this morning.

ODI #11547533WHEELS

I purchased a new Lexus NX 350 on Oct 15, 2022. On Aug 7, 2023, with 6300 miles, my tire and wheel flew off while I was exiting a 5 lane highway. The tire continued rolling and went through the windshield of another vehicle. I was able to get the car off to the side of the exit ramp while riding on the rotor. The dealer claimed no responsibility even though the car had been in for its initial 5K service that included a tire rotation 1300 miles earlier. I asked Lexus Corporate to inspect the vehicle to protect others from a potential serious hazard. Lexus said the lug bolts were shorter in style and incompatible with the standard lug bolts. In addition the jack was missing. Why would I or anyone change lug bolts when the wheels and tires are still original? In addition, this SUV has 20” standard run flat tires which does not include a jack..

Driving down the interstate we heard a big bang. It startled us. Had no idea what it was. Like someone was shooting at us. We pulled over to the side of the interstate to see what was going on. We checked the tires and side glass then saw the rear section of the panoramic roof had shattered. We had to find a store and purchase masking tape to hold it all together to complete our drive back home There were no vehicles around us and nothing apparently hit it to cause that. We submitted it to insurance and brought it to dealership for a quote.

ODI #11543722WHEELSCRASH

My front driver tire flew off as I was exiting the expressway 8-7-22. The tire and wheel continued on to go through another vehicle’s windshield, Crash # 23080049 was filed by NV Highway Patrol Trooper E Thallon # 347.The car had 6300 miles at the time of the accident. It had its first customary 5K maintenance which included a tire rotation on 5-26-23. If I wouldn’t have been exiting the freeway, this would have happened in 5 lanes of traffic whIch could have killed me or other drivers as well. Since I drove 1391 miles since service, the dealer is claiming someone else did something to the tire. I never lost tire pressure and have had no reason to have anyone touch my tires. I purchased the car new 10-15-22 and also pre-paid for 3 years of customary maintenance as well as tire and wheel protection. The car is garage kept and just used for traveling short distances to my work/local places (within 25 miles of my home). After the dealer claimed no liability, I reached out to Lexus Corp who inspected and told me to have it fixed. I and my insurance are currently responsible for repairs, rental etc. If the dealer’s service center did not over-tighten a lug nut or not tighten one enough, there is a serious problem with this vehicle that needs to be investigated ASAP.

ODI #11527971UNKNOWN OR OTHER,SERVICE BRAKESCRASH

A 3 cars collision involves this vehicle accelerating while my mom was holding on to the brake pedal. She was pulling into our home driveway, when suddenly it accelerate and hit my sister Prius and my dad's Rav4. See photos. No one pull into the driveway with their foot on the gas pedal. I strongly believe the agency should investigate this vehicle to capture a potential recall with this model. Available is a video of the door ring showing the car engine ramp up after forcefully stopped by two park cars.

Problems with the infotainment system. 8 out of 10 times won’t connect to phone or CarPlay. Need to turn off screen & turn back on a couple times. Sometimes turn car off & on.

ODI #11511252ELECTRICAL SYSTEMCRASH1 INJURY

My car was hit from the back by another vehicle. After the collision, I parked the vehicle and turned the ignition switch off, before getting out of the vehicle, the doors automatically get locked and the vehicle does not allowed to open the door even with the key card inside. I had to open the car with the manual handle from the inside. After I went out of the car, immediately the car again was automatically locked with the key card inside. I tried to open the car several times, and even with the phone application, however its remains locked. The car never opened, so I have to use an external hard ket to get access to the inside. I am very concerned about the lock system of the vehicle because someone can get stuck inside with this system failure and if there is a fire or something, this could be a very serious problem. I have kids and pets and now I don't feel safe driving this vehicle again thinking about this behavior during an accident.

ODI #11496648UNKNOWN OR OTHER

A very serious issue with inadequate side mirror visibility: The brand new 2022 Lexus NX driver side mirror does not have a range of adjustment to safely accommodate shorter drivers. The primary driver of the vehicle is 5 feet 3 inches tall and when seat adjustments have been made, the driver side mirror does not articulate inward enough, preventing the driver from seeing the side of the vehicle nor an area near the side of vehicle. The lack of range creates a very SERIOUS LACK OF VISIBILITY OF SMALL CHILDREN, PEDESTRIANS, OR PETS that maybe standing next to the vehicle during reversing. In households with small children or in congested parking lots, the lack of driver visibility of pedestrians standing next to the vehicle poses extreme risk of pedestrians being crushed by the vehicle. The danger is especially severe if the reversing vehicle needs to turn to the driver's right side, where the left front tire will travel in a larger radius than the left rear tire, potentially striking or crushing any small pedestrian standing next to the vehicle's driver's side. The passenger side mirror range of adjustment is satisfactory, the safety issue is reported on the driver's side only.

ODI #11495710VISIBILITY/WIPER

Driver side mirror vibrates excessively and prevent intended use as a mirror. The wobbling and vibrating mirror causes nausea when using and does not allow a suitable view.

ODI #11495096ELECTRICAL SYSTEM

On two occasions the car has locked us out. The auxiliary battery fails which does not allow the electric door locks to operate. It’s necessary to follow a manual procedure to unlock the driver door so the hood can be opened and the auxiliary battery can be charged and the car jump started. We purchased the car on July 30, 2022 and it has 2400 miles on the odometer. On each occasion the local Lexus dealer sent a technician to open the car and jump start the engine. Following the second occurrence we were instructed to bring the car to the dealership. They could find nothing wrong. This morning the Service Manager told me they had tested the battery five times over several days and it continued to show itself healthy. On a whim the service manager tested it again and it was dead as a door nail. The test showed a bad cell. The good news is that the problem was diagnosed and a new battery has been ordered. The potentially bad news is that the auxiliary battery in the NX450h+ may be defective in other cars.

ODI #11491938SEATS1 INJURY

2022 Lexus NX driver's seat is crooked, confirmed by Lexus dealership and Lexus field rep. The left side of the seat is back further while the right side of the seat is closer to dashboard. Lexus has confirmed that the seat is properly attached and bolted to the seat rails. An identical seat from an unaffected 2022 Lexus NX was placed in my vehicle and did not fix the crooked orientation; the replacement seat sat crooked as well. The vehicle was delivered brand new to me from Lexus with this defect. This defect may affect the crash worthiness of vehicle, seat strength, and the driver's body in the event of a car crash, as well as how the seatbelt fits the driver due to crooked orientation of seat. Lexus headquarters sent this vehicle to a frame shop to dismantle vehicle and measure frame. I have been told they cannot locate what is causing the driver's seat to be crooked but have ruled out that the problem is not in the actual seat itself or the seat rails. Lexus has also told me this problem cannot be fixed. Per the photos from the frame shop that exposed the entire frame and unibody of the vehicle, the round seat mounting holes in the framing of this vehicle appear to be elongated into egg shaped slots instead of round circles. This may also compromise the vehicle and seat’s strength and integrity, and affect the crashworthiness of the vehicle. Sitting in this crooked driver's seat for several months has resulted in a hip injury.

ODI #11486471VISIBILITY/WIPER

I have a 2022 Lexus NX. The driver's side mirror shakes excessively and consistently. It is a serious safety concern because at night there is blurry lights reflecting and makes seeing cars difficult. It is also a safety concern because during the day you cannot see the distance cars or objects are away from the vehicle as the mirror is constantly shaking. This puts myself and others at risk of collision. This also causes me to become carsick when driving. I took the car into the dealer, Lexus of Riverside, in Riverside, California two times since purchasing the vehicle for this to be fixed. They refused to fix it, acknowledged Lexus knows about the problem and said not enough people have complained for them to fix it. They are currently saying this is a normal characteristic of the vehicle but this simply cannot be. It is extremely unsafe. This issue first appeared when I purchased the vehicle and took delivery. This seems to be wide spread based on information I have seen on social media and online forums. The mirror shaking happens at all speeds.

Chart Analysis

The blue line shows 16 total NHTSA complaints filed over 3 years, with the worst year being 2023 (8 complaints, including 3 crash reports).

The amber reliability line shows an improving trend — scores have risen from the earlier years toward 94/100 more recently, suggesting the most serious issues are older and may have been addressed through repairs or recalls.

Notably, despite 16 complaints on file, no recall has been issued — either the defect pattern has not met NHTSA's threshold for a formal campaign, or a recall may be forthcoming.

Red dots on the amber line flag 2023, a year when complaints included crash events — these are the highest-severity incidents in the dataset.
