Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

On 7/24 my 21 year old daughter was driving on a side street when the car began to accelerate on it's own. She applied the brakes (with both feet) and the car would not stop accelerating. She ended up colliding with a wall which disconnected the power and the car stopped about 50 feet from point of impact.

When pulling into the garage to park the car, I put my foot on the brake to slow/stop. The car exellerated violently and the car crashed into some stored items at the back wall. I instinctively stomped harder on the brake and turned the key off. This is the first time I have had this happen - thank goodness I wasn't out in traffic or pointed out my driveway, since that is a 60 foot plunge to the lake! the front bumper was damaged and requires replacement - won't know what other damage was done internally until the repair is completed. I see online that this has been an ongoing issue with other Kia Forte owners, but Kia has not been required to do a recall "since they cannot re-create the circumstances". please investigate further before someone dies.

2011 Kia Forte. Consumer writes in regards to intermittent acceleration problems. The consumer stated when he attempted to merge onto the highway, the engine would drop to an idle. On several occasions, the vehicle would jump forward, with the slightest touch of the accelerator. The consumer has since traded the vehicle.

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.
