“While operating my 2024 GMC Hummer EV at a low speed in a school zone, I came to a complete stop at a stop sign and began making a left turn. As I initiated the turn, the steering wheel suddenly locked and became unresponsive. I was unable to turn the wheel back to the right or regain control of the vehicle’s direction. At the same time, the vehicle did not respond as expected when attempting to stop. Because I could not steer or properly control the vehicle, I collided with another vehicle. The impact with the other vehicle is what ultimately brought my vehicle to a stop. …”
