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)....

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.

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.

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...

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...

The Drivers side door (light at the bottom of the door) sparked and then the door went up in flames. At that point the electricity in the car ceased to work. The car is available for inspection at the dealership where we had it towed. If the door was closed and there was someone in the car when it happened then they would have gotten burned or worse. Our insurance company is investigating and Lexus has been taking their time and helpful in the matter. Fire Department checked out the car at the time and said the wires in the door were very hot after putting out the fire. There were no symptoms or warnings prior to this happening.

I was in a car accident on the freeway . I had just got onto the freeway so I couldn’t have been going that fast . The brakes on this Lexus Nx [XXX] to say the least . Also the collision sensor and warning also are useless. The warning light and sound didn’t go off until I was basically rear ending the other vehicle . I had a different , 10 year old car . A 2014 that would start to pump air and brake itself even when the car sensor believed it was close to a car and I wasn’t braking . This 2024 Lexus didn’t brake nor warn me in time . When I did notice the car in front of me had come to a complete stop I immediately hit the brakes but the car was still sliding forward ! This sliding motion happened once before when...

The Lexus is equipped with a large screen which displays GPS and other Apps. The car has been programmed with a pop up advertisement which states "Experience Drive Connect" that is an additional paid subscription which I do not want. I can reach over and touch an icon that removes the pop up which only pops up again a short time later. According to Stevinson Lexus and Lexus for help site there is nothing they can do to remove the pop up. Here is the safety issue: My attention to driving has been comprised by having to look at the screen to remove the pop up which only pops up a short time later. This unnecessary advertisement is simply not wanted.

Driver door suddenly opened while driving.
