It was 12/21/2022 at about 3:15 PM in the afternoon and I had just turned right into the parking lot of St. Alexius Medical Center, 1555 Barrington Rd, Hoffman Estates, IL 60169. I took a left turn, and went north about fifty feet and stopped at a stop sign. A car was stopped at the same intersection from the right facing west. As I waited for the other car to turn in front of me, my 2011 Kia Rio started to surge in speed without my foot on the accelerator. I instinctively jammed on my brake pedal to avoid hitting the car turning in front of me. Luckily, I did not hit the other vehicle, but I am concerned that this might happen again unexpectedly. The temperature at the time was about 20 degrees outside.

I was driving on interstate 8 in la mesa California at approximately 70 mph when the throttle on my vehicle stuck. I was able to shift my vehicle into neutral and pull over. The engine continued revving until I shut off the ignition. The throttle cable was stuck. I had the vehicle towed to Kia of el cajon where they diagnosed a faulty throttle cable and throttle body. The vehicle would not stop accelerating, and if there had been more traffic, there would have been a collision.

Sold a car that turned out to be a 'lemon' after only a month of having it began breaking down the most recent issue being the Cadillac converter making it a little dangerous to drive because speed is affected along with toxic fuel, whenever I drive up a hill the car is loud slow to where it sometimes rolls backwards or stops and at a green light car can not reach minimum speed cause other cars anger and strong fuel order sometimes when starting car, car cut off once at red light and when turning vehicle moves entirely too slow to when oncoming cars almost make contact
