From owner reports, verbatim
The contact owns a 2026 Lexus RZ 450. The contact stated that while the vehicle was parked in the garage, the vehicle failed to start. The dealer jump-started the vehicle and the vehicle was towed to the service center, where it was determined that a module had failed and the battery was replaced. However, the contact felt unsafe driving the vehicle. The manufacturer was made aware of the failure. The failure mileage was approximately 1,500.
Went to my car on Saturday @630p to put items in my car for church the next morning. I couldn't get into my car and my car wasn't responding to my key fobs. I called the Lexus service and was closed. I got on my app and called roadside service. As I was walking (pacing) in my garage, I noticed my rear passenger tire was flat! I asked the AAA rep about my tire. He said no replacement was in my car and the tire isn't inflated with air, but foam. Additionally, he noted me not driving the car may have drained my battery. Which was about 73% last I drove it. When he looked at my car and jumped it, he noted my 2nd battery was drained. He didn't know why. He had me leave the car running for an hour after he left. I did and the car turned off automatically after 1 hour. I called both the service department at your location and AAA on Monday morning. On Monday 8/10/2026, I got the car towed and called Gabb6 at the service center. Upon further review, the SOS button is malfunctioning and is killing my battery. Tuesday 8/11/2026, tire will be replaced but there is no solution for the malfunction other than disconnecting the SOS feature, which is a safety hazard in case anything happens. I understand there are multiple vehicles at this moment at the dealership with this issue. This should be recalled as if families with small children or citizens have an issue and connect get to their phones, the SOS feature should be functional.

From owner reports, verbatim
The contact owns a 2026 Lexus RZ-450E. The contact stated that while the vehicle was parked and attempting to start the vehicle, the driver’s side door failed to respond. No warning light was illuminated. A dealer was contacted. The vehicle was taken to dealer, and the contact was informed that the data communication module had drained the battery and needed to be replaced. The dealer updated the software and the vehicle was repaired. The contact stated that the failure had occurred approximately twelve times with the driver’s side door. The manufacturer was notified of the failure and informed the contact that the dealer could replace the data communication module only after a software update was performed. The contact stated that the failure had occurred on two separate occasions. The approximate failure mileage was 1,000.
Incident one: I was locked out of my car and needed to call Lexus roadside assistance for help. The technician struggled with the mechanical override to open the car, but was able to force it eventually. He explained the 12V battery was dead. There was nothing left on that would have drained the battery. Incident two: The following week, I was able to enter the vehicle and turn it partially on but was not able to drive the car and after I turned off the power, I was trapped in the vehicle. Lexus roadside assistance came again and jump-started the 12V battery. I left it at the dealership behind another brand new Lexus RZ with the same issue!

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
