Owner complaint summary

I was driving at a low speed, less than 30 mph, and was approaching a curve in the road. I attempted to slow down by pressing the brake pedal, but the vehicle did not decelerate. Instead, it seemed to accelerate. I panicked and repeatedly pressed the brake pedal several more times, but the vehicle remained out of control. The vehicle left the roadway, went down a steep slope, struck bushes and tree branches, and eventually came to a stop. All four airbags deployed, and I observed smoke that appeared to be associated with the airbag deployment. The front ,side,underside and lower portion of the vehicle sustained impact damage. At no time before the accident did I observe any warning lights or messages indicating a problem with the braking system or any other vehicle system. Based on my experience during the incident, I believe the vehicle experienced a brake malfunction, as the brakes did not respond when I attempted to slow or stop the vehicle.
