Car stopped accelerating three times this week on trip. This occurred two years ago and Kia dealer could not "duplicate" the problem. The car engine doesn't stop but it's as if it goes into neutral; like the transmission disengages. It then bucks, accelerates, and dies. After about an hour, it's fine.

When parking and trying to put the car in reverse our 2006 Amanti Kia lurched forward and accelerated down the street. I was the passenger and had unbuckled my seat belt in preparation of getting out of the car. Seeing that I was not belted in, I leaned over and saw that my husband had his foot on the brakes and not on the accelerator. The brakes did not engage, nor could the car gear down. The car kept accelerating faster and faster. The car was steered around a turn and finally lost control due to the speed and crashed through two tree shrubs, through a closed garage door, took out the main post in the garage, and hit the parked car in the garage. The airbags went off and the car stopped. 911 was called and my husband and I were taken to the hospital. The car was totaled! the car had only 20,000 miles on it. No lawyer will represent us because our injuries were not severe enough to warrant a suit against Kia for product liability.

When starting up from a stop, the car starts-up very slowly for about 4 or 5 seconds, than appears to jump into gear and takes off like a rocket. This occurs several times a month. The car has been taken back to the dealer several times, but it has not happened when they test drove it so nothing has been done to fix the problem. We complained to Kia, and have a complaint no. Also but nothing was done.

2006 Kia Amanti speed control problem at minimal throttle the car would lurch or move very slow and then would buck mostly in cold weather. Never know when this will happen. Started at 4900 miles and still having problem at 94000. Dealer never can recreate problem. We have had the car in many times and its in today still no fix. I believe this car will get us killed. If you pull out in traffic and it only goes 10 miles an hour guess what's going to happen. Does anyone care NHTSA or Kia. I think not!

2006 Kia Amanti - vehicle will "lag" when the accelerator is depressed on occasions and will also "lurch" forward while trying to brake. There are numerous other Amanti owners nationwide who have experienced this problem. Kia refuses to acknowledge that a problem exists. I have since traded the vehicle in on a Honda. To see the extent of the problem go to "edmunds.com" website and you will find numerous owners with this problem.

Bought 2006 Kia Amanti with 6500+ miles driven by deakler manager experienced sudden acceleration upon initial start up two or three times when car seemed to continue ok after a couple of sudden sudden jumps (this when I first tapped accelerator then stoppedc doing this. This has since happened many times not all the time.to date it has happened 9 0R 10 times. On two occasions car would not shift into neutral but surged at a traffic light dispite my efforts to stop car. I shifted to neutral and stopped car the car worked ok when I shifted into drive thereafter but did it a second time a few weeks later. I did the same thing (shifted to neutral) and it functioned ok. The dealer tested car (on computer and insisted it was ok however when it continued I called Kia they refereed me to another dealer (ball Kia) nand again tested it but could not find anything wrong. However it is still doing this and I have been back several times. Ball mechanic said to keep driving until it does it so often that they can retest it. I am concerned that if it happens when my wife is driving. She may not know what to do and have an accident.

- the contact stated that while attempting to accelerate from a stop the vehicle would not accelerate. This was an intermittent problem. If the vehicle did accelerate, it would do so very slowly and the rpms were running as though the consumer was traveling at an accelerated speed. The contact stated that this could happen anytime of the day. The contact stated that sometimes when trying to pass another vehicle on the highway at a speed of 60 mph the vehicle didn't accelerate into overdrive. The contact took the vehicle to dealership on several occasions, the most recent being 11/27/06. The contact did have the service mechanic perform a test drive and he did notice the problem with the acceleration. The contact stated that the dealership has contacted her and told her to come in and pick up her vehicle, she was told that they had to reprogram the computer system in the vehicle. Updated 1/22/2007 - the dealer returned the vehicle to the consumert with any repairs being made.
