After sitting all night -- Started the car which started normally. But the instrument gauge cluster remained totally black except for the warning symbols in test cycle. The infotainment screen started properly. But the gauge cluster remained black. No speedometer, gas gauge, tire pressure etc. Just black. Tried multiple times, turned on and off, killed the electronics by holding the volume button, got out and opened the hood then opened the fuse box and found nothing wrong (pressed and wiggled the fuses) no loose fuses. opened the door and got back in. Car and all gauges started but the center gauge cluster took longer than normal to boot. That was in mid June 2026 2 months ago and has not reoccurred. In searching for solution discovered that the opening and closing and reentering the car is a workaround (sometimes) so I think it was the fix.
NHTSA complaint #11757239 — an unverified report by a vehicle owner.
Our 19-month old Lexus NX450h with under 7,000 miles on it was not driven for a week. When we went to start the vehicle this morning, the car would not unlock via the keyfob, credit card key or app. The car required AAA to open the doors and jump start it. This is a very common failure with the 12-volt battery in the Lexus NX hybrids. This could result in a motorist being left stranded somewhere.

On 2026-07-05, my car started except the digital instrument panel was blank/black. This meant the digital gas and battery gauges weren't visible, in addition to the speedometer, etc. I tried restarting the car to see if it was a fluke but it did not come back. On 2026-07-06, the car worked fine / as expected, but after a google search, it seems like this happens to other owners as well in the past with no clear reason why. Wanted to report in case it becomes a larger thing.

3 unresolved safety defects on 2024 Lexus NX 450h+ plug-in hybrid leased May 2023: ELECTRICAL/BATTERY: Rear seat occupant sensor produced continuous false alerts since weeks after lease began, preventing vehicle from locking. High-voltage components including on-board charger located beneath/near the rear seat area per dealer representation at time of sale. Service manager acknowledged liability in writing July 2023. Lexus TSB L-SB-0035-24 addressing battery monitor module failure (DTC P162B87) never applied. Recall 25LD01 covering high-voltage floor wire corrosion unverified for this vehicle. Not charged since approximately April 2025 — over one year — due to fear of battery malfunction, fire, or explosion. Operating exclusively on combustion engine, eliminating primary plug-in feature. Reported in writing for 2 years 8 months. Never repaired. GM confirmed in writing February 2026 defect never submitted to manufacturer. DRIVETRAIN/TIRES: Severe premature tire wear from approximately 2,252 miles. At 7,800 miles dealer declared vehicle unsafe for freeway driving. Owner used alternative transportation for court appearance due to safety warning. Dealer's own alignment printout January 2026 shows multiple out-of-specification values. All 4 tires replaced after 72 consecutive days dealer possession, classified as goodwill, never submitted as warranty claim per GM written admission February 2026. HVAC/BIOHAZARD: Persistent mold/mildew odor from HVAC since early in lease. Service advisor initially attributed cabin odor to rat feces in engine bay entering cabin through air circulation — admitting biohazard exposure to occupants. Rodent nesting caused by manufacturer's soy-based wiring insulation. Rat feces constitute hantavirus and salmonella risk. Same defect across three consecutive vehicles from same dealer. Engine bay sanitized and evaporator cleaned during 72 days, classified as goodwill only, never submitted to manufacturer. Documentation available for inspection.

Battery was DEAD after being parked for one week. Car was in residential garage (outdoor temp about 10 degrees. garage temp measured 46 degrees. Please Note: The SAME problem happened to my 2025 plug in RX and 2025 plug in NX. I doubt this is a coincidence and there are plenty of websites that indicate a significant problem.
NHTSA complaint #11717886 — an unverified report by a vehicle owner.
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.

NHTSA has issued service bulletins regarding Lexus servo motor issues, primarily affecting the HVAC system, because these motors can have internal electrical malfunctions. This malfunction can cause symptoms like uneven or inconsistent air temperature from the vents, lack of airflow from selected vents, improper mode control, and the storage of Diagnostic Trouble Codes (DTCs) related to the damper control servos. This is an issue because it affects Safety and Convenience due to the following: While these issues primarily affect comfort and convenience by disrupting the climate control system, a malfunction of other servo motors (which control things like air flow direction or even steering in other situations) could create a safety risk. Experiencing this in my 2015 NX 200t today made me feel unsafe, as the vents were blowing out extremely hot air. And during hot Texas weather that is unsafe, and I have children that I have in the car with me at times. The Lexus dealership in Grapevine Texas is asking for $2,600+ to fix servo motor 1 and 2 after they ran diagnostics. It seems as if a vehicle that was in the same year and is experiencing the same exact issue as other vehicles in that year should also be covered as those that got it fixed under Lexus’ warranty. What makes the NX model different from the 6+ other models that Lexus a covered under the NHTSA safety bulletin/ recall?
NHTSA complaint #11690136 — an unverified report by a vehicle owner.
On [XXX] my Lexus would not start properly and then I heard noises which were associated with the battery closing down. This included locking all the doors. I was trapped in the car for 50-60 minutes until a repair person unlocked the door. This is a safety issue because the temperature where I live (las Vegas) is over 100 degrees months of the year. According to other Lexus owners, mine was a somewhat common experience. Some people have had the battery fail while driving. A recall to fix the problem is needed. When I contacted both corporate Lexus and my dealer they played dumb and told me to drive the car more often, but no one could specify how much that would be. Purchased in February, 2023 the vehicle has over 25,000 miles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle: 2024 Lexus NX 450h+ (plug-in hybrid) Odometer at latest event: ~14,600 miles Dealer: Motor City Lexus of Bakersfield (Bakersfield, CA) Lexus Corporate Case #: 250823001008 Complaint Description: While driving, the vehicle suddenly lost all electrical power without warning on two separate occasions, causing the instrument cluster to go dark and an immediate loss of power steering and brake assist. I had to coast to a stop—this is a serious crash risk. Timeline of events: • 08/20/2025 – In-motion total electrical blackout with loss of steering/brake assist at approximately [speed] mph. • 08/21/2025 – Dealer replaced the 12-volt battery. • 08/23/2025 – Repeat in-motion blackout with my children in the vehicle; dash went dark, loss of steering/brake assist, coasted to a stop. • After 08/23/2025 (at dealer) – During diagnostic testing, a dealer technician reproduced the same failure (total electrical power loss while moving, dash dark, loss of steering/brake assist). This confirms a repeatable safety defect. • There have also been three additional immobilizations that required Lexus Roadside Assistance on other dates. Current status: Vehicle remains at the dealer for the second repair attempt. I am within the 18-month window from delivery (Mar/Apr 2024). Safety concern / suspected area: Sudden total electrical loss while driving with loss of steering/brake assist. Please investigate potential defects in the 12-V/DC-DC charging system, hybrid/electrical system (inverter/DC-DC/grounding), main fusible link, or related wiring/connectors/grounds that could cause complete power loss while the vehicle is in motion.
NHTSA complaint #11684075 — an unverified report by a vehicle owner.
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 resolve the matter despite multiple follow-ups. Additional issues include malfunctioning GPS, flickering interior lighting, and system errors suggesting possible electrical instability. I no longer feel safe operating the vehicle due to the ongoing risks and lack of manufacturer response. This is a serious failure of duty to inform, inspect, or repair — and may indicate deeper electrical or structural defects that pose risk to others.

My 2024 Lexus NX 450h+ experienced a complete 12V battery failure after normal short-distance driving, leaving me stranded without warning. This is a known defect in Lexus plug-in hybrids that the manufacturer has not properly disclosed to buyers. Incident Details: After several short trips (all under normal driving conditions), my 2024 Lexus NX 450h+ failed to start. The vehicle was completely non-responsive. Because the doors and liftgate were locked and inoperable, I was forced to crawl through the rear cargo area with a pre-existing mobility issue (bad leg), causing significant physical pain and emotional distress. I later had to visit the Emergency Room due to pain and strain from the incident and was prescribed medication. When I reported the problem to Lexus Corporate, they initially attempted to shift blame onto my roadside assistance provider (AAA) instead of acknowledging the mechanical defect. No solution was offered to ensure the vehicle’s reliability for daily use. Ongoing Concerns: •Lexus has not issued a recall or fix for the widespread 12V battery failures affecting plug-in hybrid vehicles. •This issue poses a significant safety risk, particularly to older drivers, disabled individuals, and anyone who relies on their vehicle for essential transportation. •I purchased this vehicle at a premium price, expecting reliability, and it has failed in fundamental ways. •Being stranded without warning and physically harmed while trying to exit my own vehicle is completely unacceptable for any car, let alone a brand-new luxury model. Given the known nature of this defect (widely reported by other owners online), Lexus must be held accountable for addressing the safety hazards caused by faulty 12V battery systems in its 2024 NX 450h+ plug-in hybrid.
NHTSA complaint #11656901 — an unverified report by a vehicle owner.
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.

[XXX] I was Braking while pulling into my Carport almost at the Rear curb, when Suddenly and without Any Warning, my 2022 NX 450h Accelerated Rapidly and sent Me up a short Hill and Crashed into a Large Tree While I still had my foot on the Brake. Then it kept Accelerating and the Front tires Dug a 4in Deep Hole while they were Spinning still with My foot on the brake! I was able to get the car into Reverse and backed it down the hill and turned it off. It wasn't Drivable due to the Extensive Front Damage, so I had it Towed it to my Local Roseville CA Lexus Dealership service and they Told Me to "Get The [XXX] out of Here". Then I had it Towed to a Repair Shop recommended by Lexus. Contacted Lexus to have an Investigation Started and it Took Almost 1 Month to Have an Investigator come out to Look at and had it Towed to Roseville Lexus To obtain the Crash Data from the Black Box. Lexus "Reviewed the Data and Found there was an Unexplained Sudden Acceleration 20 seconds before the Car jumped the curb and Crashed into the Tree." They Did Nothing. I Had My Farmer's Insurance Pay over $19,000 to Have My Car Fixed- it Took 4 mos due to Backordered Parts. Needless to Say, My Car Insurance has Skyrocketed as this is Labeled "At Fault". I Noted the Same Scenario on a NHTSA Complaint #11527971 dated 6/20/23. 2nd Complaint is for the Electrical System and a Complete Lockout on [XXX]. Went to Unlock my car and it wouldn't Unlock. Tried Multiple times, then popped off Key Cover on Handle and used the Valet key to unlock the Door. Once inside, The Car I left the Door open and when I pressed Power, it Wouldn't Start, Nor Shift, but the Steering wheel Would Turn Still. Had to have the Car Towed to Lexus. They Found that the 12v Battery had been Drained and They Claim it was "due to the Security System malfunctioning". I am due to pickup the Car after a Supposed "Fix" but They Refused to Replace the Battery at My Request. I am Very Concerned with These Issues.

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)
