I was driving north on [XXX] when I felt a slight pull to the right. I figured it was my lane assist even though I was in my lane. Seconds later it felt like if someone was in my passenger seat and just yanked my steering wheel to the right hitting the guardrail. My whole tire and the assembly was off but everything was still intact to the tire. The tie rods, axle, ball joints, the whole assembly. During investigation I was told by the mechanic that the stabilizer bar was a clean break.
The contact owns a 2025 GMC Terrain. The contact stated that while his wife was driving approximately 40 MPH on wet roads, the brake pedal was depressed, but the brake pedal was stiff, preventing the vehicle from slowing down as intended. There were several unknown warning lights illuminated during the failure. The accelerator pedal was released, and the vehicle rolled to a stop. The vehicle was turned off and restarted, but the check engine warning light remained illuminated.
