2010 Kia Soul Vehicle speed control Problems

“My wife and I were driving on the highway going about 70 when all of a sudden the car seemd to shift down to 3rd gear almost having the car behind us rearend us. Has been happening all the time if we go over 65 or 70.”

“On two separate occasions, I have experienced unintended acceleration, once when the cruise was on and once when it wasn't. The Kia SOUL would not respond to braking or slow down to less than 20 MPH. Luckily I was on the interstate or four lane both times and had time to get over on the berm and put car in neutral and then park and then turn off immediately. I tried to restart and the engine revved up to 7,000 in park. I let car sit for about 15 minutes...first time when I tried to restart it seemed to be okay. I drove it for about a month before second occurrence. …”

“2010 Kia SOUL 5 door wagon 2.0 l mt 5 speed transmission the car over revs between shifts and has a soft brake pedal that goes to the floor and as your brake pedal goes down at stops your foot touches the foot feed and causes the car to revs up while stopping.

“I own a pre-owned 2010 Kia SOUL! With approximately 47k miles, clear title and no accidents. On sunday 12/29/13 my car experienced sua (sudden unintended acceleration). I was driving approximately 35 MPH, approaching a rotary, when my car suddenly accelerated on its own. The rpms spiked up to 4000-5000 and my car lunged forward and the engine was racing very loudly. I had to pump the brakes multiple times to decelerate and bring the car to a complete stop. This incident is now the 4-5th time I have experienced sudden acceleration (within 1 year), usually happening between the 35-45mph range. …”

“Factory cruise control was in use at approximately 45 MPH. When the brake was applied, the cruise control did not disengage. Instead the engine raced in an attempt to maintain the car speed at 45 MPH. I tested the cruise control the next day 2 times at different speeds and each time the cruise control would not disengage with application of the brake. It did disengage each time when the cruise control on/off switch was depressed. The cruise control has worked without any problems prior to this.”
