When pushing the gas pedal after stopping for a light, engine is sluggish and will not accelerate, almost causing an accident. Had it in the repair shop several times, cleaning the accelerator position switch contacts, and various other wiring checks. The last repair replaced the computer control module at a cost of more then $2,000. This problem has been reported many times by other owners on the repairpal web site. So far, no recall notice has been issued. Kia is reaping the benefits of all the problems we all have been having.

After driving the car slowly lost power, my foot was on the gas, but it would not go any faster. I noticed this problem seems to happen after the car has idled for long periods. Then it gets power back after car has left to set 30 minutes to an hour. This has happened 3 or 4 times this year. On the interstate and city. Leaving me and my family stranded each time. So far this has just happened in the hotter months. Once it sits it doesn't happen again. Making it hard to take any where to get it checked out. The car stereo also is cold natured for some reason. In the winter it likes to change stations or cds until the car has warmed up. I have never heard of this.

Car just loses power then has an acceleration of power where it is out of control. This is a 2006 Kia Amanti and has the problem since we bought it 2 years ago. Kia has not been able to fix it even though we have had it at the dealer's several time. What happens is you try to accelerate and there is no power, then the car has a power surge which takes the driver unaware. This is a very dangerous situation. It only occurs about once a month and the dealer says they can't duplicate the problem. They have changed the throttle sensor the last time and it didn't fix the problem.

The slightest touch of the gas will cause it to lurch forward, but also it lags, you can push the acceleration deep and still not much response. Usually this is what happens I'll back out of the driveway, put into drive, touch the gas, and it will lurch. Back off the gas lurch again. Full stop and then the car will run just fine. I have had the car into the dealer they say they can not find a problem.

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.
