2024 LEXUS NX

STEERING:COLUMN

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2023 Toyota Corolla, Corolla Cross, Corolla Cross Hybrid, Highlander, Highlander Hybrid, Tacoma, Lexus RX350, 2023-2024 NX250, and NX350 vehicles that may have been incorrectly repaired under previous NHTSA recall number 23V-480. An electrical connection inside the steering column's spiral cable assembly may be insufficiently welded, causing the connection to separate and deactivate the driver's air bag. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 208, "Occupant Crash Protection."

Risk: A deactivated driver's air bag will not deploy as intended, increasing the risk of injury during a crash.

ELECTRICAL SYSTEM

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.

ENGINE

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.

ELECTRICAL SYSTEM:12V/24V/48V BATTERY

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.

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.

LANE DEPARTURE: ASSIST

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.
