Open the full vehicle complaint log (all categories)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.
