My son was driving the car at the time and the steering locked up on him taking him to the left and he had to jerk it back very hard to unlock it to stay on the road, thank goodness there was no on coming traffic. This has happened several times and it also locks when put in park and I can't get it to start or get steering wheel to move.

Living only 3.7 miles from my work I drive to work 2 times daily, mon- fri, round trip. I come home for my lunch hour. Never being able to drive faster than 20-30 MPH due to the roads & busyness of them during that time I had never had a problem before. I had noticed prior to my accident that at times my 6 speed 2011 kia forte koup was very resistant to put it into 1st gear. Almost as if it was locking the shifter out. Having it looked at by a kia dealership, they claimed it was just "user error"...perhaps my foot wasn't pressed all the way down on the clutch or b/c I'm a woman? This was not my first manual car! So as I left my house for work after lunch I noticed that every time I upshifted my car did this jerking thing, almost as if the brakes were working when they shouldn't have been. I told myself when I get to work (in 8 mins) I would call my brother who is a mechanic. I didn't get my car to work safely. I ended up rear ending a truck who rolled forward into a new camaro, everyone was ok thank god! As I approached the stop light w/3 cars stopped at the red light already. I proceeded to slow down .3 miles from the light & it seemed as if it was slowing down in slow motion. When I realized my brakes weren't actually slowing the car down from 28mph, I did everything I could to stop by car before crashing. I tried down shifting as well as slamming down on the brakes. It was as if my brakes were non existent. If I had time left I would have yanked up on the e brake...I was only 1.2 miles from my work! No airbags went off nor was my car totaled. I paid cash for this car in 2011 & since having wrecked I've felt it was not safe for my family to drive. After fixing the repairs & paying my deductible I traded the car in. I purchased a brand new car which I now have a car payment on. I hope that this issue can be discovered & resolved before it hurts anyone severely.

When going 60 on the highway the car suddenly dropped down to 40 and I had to pull off the highway. Car was then taken to the dealership where the whole transmission was replaced. Upon recieving the car again it would jerk and stall when accelerating. Car was then taken back to the dealer and a "relearn" of the transmission was performed. This has not stopped the problem and has made it worse. It now jerks when stopping and when accelerating and peeds of 5 mi/hr or more. As well as when first shifting the car out of park.

Was driving at normal highway speeds felt this sudden jerk (like I had been hit from behind) and the car would not go. When I got pulled over I placed it in park and then back into drive it would not pull forward. Tried to put into the manual shift side and it would not do anything there either.
