As I was navigating a turn onto a highway on-ramp, the vehicle unexpectedly decelerated or attempted to brake autonomously, accompanied by a sudden loss of power steering assist. This created a hazardous situation, nearly causing a collision with the guardrail. After safely bringing the vehicle to a stop, the dashboard illuminated with numerous warning lights and messages such as: Electric Power Steering System Problem. Steering Assist Not Available. Do Not Drive. Brake System Problem. Brake performance may be reduced. See your dealer. Lane Keeping Assist System Problem. See your dealer. Collision Mitigation Braking System Problem. See your dealer. Road Departure Mitigation System Problem. See your dealer. Low Speed Braking Control Problem. See your dealer. The power steering light and brake system lights came on. This incident occurred on April 12, 2025 and then occurred again on April 20th. The dealer took the vehicle in on May 9th and told me they can not reproduce the problem. This has the potential to cause life threatening injuries or even death.
