The contact owns a 2023 Lexus ES 250. The contact stated that while driving approximately 40 MPH, the vehicle abruptly stalled. During the failure, the vehicle lost power brakes and power steering functionality, with the messages "High Power Consumption Temporarily Limited", "Braking Temporarily Disabled", and "Power Steering Temporarily Disabled" displayed. The contact was able to safely park the vehicle. The vehicle was later jump-started, but the failure reoccurred. The vehicle was jump-started a second time and driven to the local dealer, who diagnosed the vehicle and determined that the alternator had failed due to several electrical charging ports being used at the same time. The contact was informed that the alternator needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was 67,995.

While driving on the highway, whenever you approach an exit or an intersecting part of a highway, the lane keep assist will jerk hard towards that exit or towards the direction of the nonexistent line on the right or left side of the lane. Weather that line of that lane has faded out or is part of a type of highway intersection. Since the car drifts in between lines of that lane (while in LANE KEEP ASSIST LKA), it is hard to tell initially what the car is trying to do. Then it pulls hard to the right or the left, depending on where that line has disappeared. While there’s always at least one full line of that lane visible. I’ve already almost been in several car accidents since I got this car last April. Also I am driving a 2025 Toyota Corolla and I’m having the same exact problems. This is unsafe for everyone.

The contact owns a 2023 Lexus ES 300. The contact stated that upon coasting into a parking space, the contact tapped the brake pedal; however, the vehicle independently accelerated. In an effort to avoid hitting the building, the contact steered the vehicle to the left, away from the building; as a result, the contact drove into some hedges. The contact's foot was on the brake pedal throughout the failure, and the vehicle eventually came to a stop. The contact stated that a "Parking Support Brake Malfunction, Visit your Dealer" warning message appeared on the instrument panel. The air bags did not deploy, and no injuries were reported. The police were not called to the scene, and a police report was not filed. The building's hedges were destroyed, and paint marks were left on the side of the building as a result of the vehicle scraping the building. Despite the failure, the contact managed to regain control of the vehicle and drove home. The next day, the vehicle was taken to an independent mechanic, where it remained in their possession; the vehicle had yet to be diagnosed or repaired. The manufacturer had yet to be notified of the failure. The failure mileage was unknown.
