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!
