2024 LEXUS NX Complaints

The incident happened on August 27, 2025, at about 8:30 in the morning when I was trying to park the car in a parking lot. As I came to the parking space to park the car with my foot on the brake pedal, the car accelerated all of a sudden after it had stopped before I could shift the gear lever to “Park”. The car went over the curb. I reversed and tried to park the car again in the same spot. The car accelerated again and went over the curb, and this time ended up going all the way to the two-way traffic road located ahead of the curb. Fortunately, there was no traffic on the road at that time and no pedestrian on the sidewalk, and no one got hurt. The car stopped in the middle of the road. I drove back to the parking lot and tried to park the car again in the same spot. This time the car stopped without any incident. The dashboard said, “System Malfunction” and said to take the car to the dealership. I drove to the Lexus dealership without any incident. There was significant damage in the front and both sides of the car. I told Lexus what had happened. A case manager was assigned. An inspector was sent to inspect the car. After the inspection, he sent me a report. The report was technical in nature and had graphs and data points without any explanation. I could not understand the report. He told me that the report was sent to Toyota and Toyota would get back to me after they had analyzed the data downloaded by him. Toyota sent me the report, and the report said that my foot was on the accelerator at that time and the car functioned properly. I am pretty sure that my foot was on the brake pedal at that time and not on the accelerator. Toyota was not willing to answer any questions I had and told me to get a second opinion. Currently, my car is in the auto body shop being repaired via my insurance. Even though, no further incident has happened to date, I am afraid that this could happen again in the future, possibly badly hurting or even killing people.

Driver dash does not illuminate upon starting vehicle. No MPH or other drives gauges display.

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.

Purchased this 2024 NX in October 2024. Since purchase the CarPlay aspect of the car where you can talk to text and voice call has not been functioning normally. It cuts in and out of bluetooth so if I am on a hands free call with someone, sometimes it cuts over to the phone randomly and won't connect to the car. The talk to text feature and any talk to the car feature for CarPlay doesn't work as it does not recognize any voice it just hears what the car is playing and asks for repeating. This is a known issue in this vehicle. I have brought it up to Lexus on each service and they are aware but it apparently needs a software update that they have been waiting on for over 1 year. This feature is crucial for the driving that I do as I need to be able to respond to work calls/texts using the hands free feature as GA is a hands free state and it is illegal and unsafe for me to have my phone in my hands while driving.

The contact owned a 2024 Lexus NX530. The contact stated that while parked and turned off, a few hours later, she observed a fire emanating from the front of the vehicle. The fire then spread to another vehicle that was parked in front of the vehicle. The fire department arrived and defused the fire. The contact stated that the fire department advised her that the fire originated from the engine compartment. The vehicle was towed to a salvage lot. A fire report was taken, and a police report was pending being filed. The contact mentioned that while driving the vehicle prior to the fire, there were no warning lights illuminated. The manufacturer was not notified of the failure. The failure mileage was unknown.

Was parking at grocery store, very slowly advancing into parking space when car suddenly accelerated and ran into a brick pillar, jumping the curb.

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.
