NHTSA Complaint #11544858 — 2023 LEXUS NX

Vehicle was remote started using Lexus app. Wife entered vehicle using rear door along with infant daughter. She sat in the back seat to feed her a bottle. When ready to leave, she placed and secured our daughter in her car seat. She then opened the rear passenger door to get into front driver seat to begin driving. On opening the door, the car alarm went off. She exited the vehicle through the rear passenger door. She shut the door and as she as waking to the driver door, the vehicle locked itself with the keys, phone and our daughter inside the car. The alarm startled her and she left the keys in the rear seat. The vehicle remained on. When remote started via the app, the car remains on for 10 mins. She got help and dialed 911.. vehicle shut off 3-4 mins prior to fire department arriving. They tired to open the door but were not successful. Ended up breaking the window to remove our daughter. Thankfully she was ok. I am unsure how the car locked itself with the keys still inside. The keys were in the rear seat by the child car seat. Took vehicle to Lexus dealer. They stated there were no faults with vehicle. Referenced page 63 of owners manual which states car may not detect keys if left on top of console or door pockets… which was not the case here. Have not attempted to re produce issue. Very concerned this may happen the someone else. There were no warning lamps on.
