I was driving extremely slowly pulling into a parking spot. I applied my brakes but the car experienced Unintended Acceleration. The vehicle felt like it went into another gear, and It jumped the curb on its own, ran over some shrubbery, and crashed into the porch of a condominium which stopped the car. The air bags did not deploy as I was only going approximately 3 m.p.h. The sensors that should have prevented me from jumping the curb, running over shrubbery, and crashing into a building failed. Kia Consumer Affairs performed a forensic inspection and found nothing, yet I am positive that this vehicle is unsafe to drive. There were no warnings prior to the incident. I could have been killed or hurt or killed others.
