The contact owns a 2022 Lexus NX450H. The contact received notification of NHTSA Campaign Number: 23V478000 (Electrical System) however, the part to do the recall repair was not yet available. The local dealer was made aware of the issue. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

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.

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.

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.

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.
