| Description of the problem | "first" time problem happened was july 3, 2016 with my 2006 kia optima. I was sb on hwy i25 in cs, co. Speedometer read 25mph as i was coming off the on-ramp. I accelerated to 40mph into flow of traffic. I felt a lurch & the vehicle automatically accelerated. Speed went from 40mph to about 60 mph without depressing accelerator. Breaking did not slow it down. I felt car was going out of control. My passenger reached over & turned ignition switch off & on quickly, to decelerate & accelerate. This helped car slow down when key was turned off to the first click & helped maintain an adjusted speed as traffic was in-front & in-back. We kept doing this until car slowed down enough to pull over to right shoulder. Key was completely turned off & car was at a complete stop. Car was towed to mechanics. Diagnostic was performed using engine analyzer. It was road tested multiple times & didn't it duplicate my experience. This happened again sept. 10, 2016 as i, again, entered hwy i25 so. I was driving alone. My speedometer was 40 mph, in heavy hwy traffic. I once again "felt" lurch of car. This time it "stuck" at 40 mph. It didn't slow down when i braked, it continued at 40 mph. I continued to brake & speed did slow a bit. My foot was totally down on break when it was still auto accelerating at the hwy exit ramp; now slowed to 26 mph as i continued holding brake down. Finally speed was down to 23mph as i drove into a parking lot (no cars were moving in & out at the time). I turned the key off completely; my foot was still on the brake & the car came to a lurching haul at that time in the middle of the parking lot. I waited about a minute & then started the engine again with my foot on the brake. I was able to pull into a parking slot. I started it & very slowly drove home, but not on the hwy. I maintained speed of 25-30mph. It was only about 1k between the 2 incidents. |
