NHTSA Complaint #11517298 — 2023 TOYOTA COROLLA CROSS

Just a couple weeks ago, my 16 year old daughter was driving our NEW 2023 Corolla Cross when she came to a busy intersection and had to stop for the red light. She reduced her speed to make the complete stop and WITHOUT engaging the ECO system (Stop/Start feature using the brake) the vehicle completely shut down and locked up on her with the "Power Steering Low" warning as well as some description about the brake. She asked what happened and what should she do. I turned the Hazard lights on and I asked her if she had tried to engage the ECO system Start/Stop and she said no. I told her to see if she could engage the Stop/Start by firmly pressing on the brake, she could not. I told her to put the car in park and again try to engage the ECO system, she could not. I told her to turn the vehicle off while in park and then restart the car. When she turned the car back on the warning cleared and she could drive the vehicle a few blocks to work. It was raining, not heavily, and we had the windshield wipers on. The "Power Steering Low" showed another time when I had the car idling in the parking lot with the wipers going waiting for my son after his game. I had to turn the car off. Numerous occasions the "Battery Charging" warning will appear when I have tried to engage the ECO system Stop/Start. One day I could not get the ECO system to engage no matter what I did, NO additional accessories were on. Same as the Power Steering Low issue unknown but, my daughter has experienced the wheel firmly locking up where she cannot control the wheel while centered in the lane. The lane assist seems to engage aggressively when not needed creating a temporary situation where the drive cannot control the wheel. My dealer has had the car 8 days without being able to replicate any error and unfortunately there SUBSTANTIAL DEFECTS DO NOT log in the cars history. Most concerning is the lack of logged warnings which the dealer says they can't diagnose the issue. Huge safety concern!!
