NHTSA Complaint #11616534 — 2024 LEXUS NX

On Sep 16, 2024 I purchased a 2024 EX450 Plug-in Hybrid. During the purchasing process that new car delivery person recommended using the Lexus app which I installed. From Sep 18 through Sep 23 I drove the car in the EV mode around my community. I put on approximately 15 miles. On the morning of Sep 24, 2024 I needed to go to an important meeting. On Sep 23 in order to prepare for a 40 mile drive I plugged the car in and obtained a full charge. At 6:15am I opened the hatch and packed my car. The rear hatch opened without any issues. At 6:30 am I tried to enter the car and the car was locked. Fortunately I left the hatch open and I was able to crawl through the back of the car and open the car doors. I then tried starting the car and the car would not function, no click, no lights, all electric systems were dead. I reviewed the app on my phone and what was 36 miles 100% charged the previous night now stated 0% charged and -1 miles. Something had discharged the car overnight. There were no lights on or doors left open. The car was transported to the dealer. After a day of testing the battery (which was within spec) and the functions of the car the tech recommended the app that I used to monitor the charge status and other status's of the car including the ability to remote start the car be removed from my iphone. It is thought that the car overly communicates with the app thereby draining the battery. Doing on-line research I learned that others have come to this same conclusion. I am requesting that Toyota Motor Company immediately investigate this issue and if the app is the culprit immediately issue a warning to all its consumers that use the app to immediately remove the Lexus app from their phone. If a person had placed their children in a car seat, activated the hatch and closed the doors the doors would automatically lock. A caregiver could inadvertently lock their child in the car.
