Just 2days ago my car started jerking real bad and also my transmission felt like it was stalling and the car was loosing acceleration power.then after a short hesitation the vehicle,while backing in the driveway accelerated and was hard to stop.today I noticed a small tremble in the transmission and my car almost went in traffic if I had'nt put the vehicle in neutral and applied force to the brakes,my vehicle was in motion on both incidents,I'm not afraid of my vehicle, but I don't want to cause or be in an accident.

Since purchasing my 2005 kia amanti air bag light has been on; the vehicle has never experienced an impact which would cause the airbags to deploy neither have any of the airbag components ever been tampered with. The throttle control of the vehicle is extremely sporadic and often causes hesitation, lurching, no acceleration, and even loss of all power. I have had the dealership update the ECM and the tps replace but the problem still persisted. I noticed the throttle body plate was extremely difficult to actuate so I then purchased another throttle body and replaced my older one. Everything functioned as should be expected up until approx. 3 months ago the issues started back up again. I noticed the throttle body motor had started to become increasingly hot to the touch indicating an excessive amount of resistance within the motor circuit. Being that the problem is recurring, I feel the issue is located either within the engine wiring harness or the engine control module and it, as well as the ruined throttle body motor, need replaced at the cost of the kia motor company. The issue can, and has, caused numerous accidents, stalling in heavy traffic as well as lurching and speeding away of vehicles. A major safety issue is present and needs to be addressed.

While attempting to apply pressure to the accelerator pedal the vehicle hesitated. This occurred intermittently car appeared to be stuck in first and would not shift. The car does not accelerate smooth in lower gears - also, car lurches when stopped at intersections - rpms are erratic dealerships say they cannot replicate this has been ongoing for over one year cannot afford to drive this car / cannot afford trade in- researched on internet found hundreds of similar complaints at just one site - http://www.kia-forums.com/archive/f-221.html

Pulled out into a busy intersection - car crawled - did not respond to acceleration - lurched quickly into traffic almost causing an accident. Drove further down the road at 40 MPH, car acceleration died almost completely, service engine light came on. I pulled off road, called my local kia dealer from whom I bought the car. They were no longer handling kia, had to have car towed an hour away and was told the throttle wire assembly was cleaned out and repaired. This was in january, 2008. February 2008 I took car to shop to have brakes checked - tech took it out for test drive. When he came back he asked if it had a problem with severe hesitation. I told him it was fixed last month (under warranty). He said he pulled into busy traffic twice and the vehicle failed to accelerate, almost causing 2 accidents. I drove the car back to work, acceleration failed once again and check engine light came on and stayed on. Going to have to have it towed an hour away for them to look at it again - meanwhile I'm without any form of transportation ( cannot get loaner) once it's fixed I will have to pay someone to drive me an hour away to pick it up! They need to figure out the problem - I have seen numerous complaints on the internet about this. It's causing me to be paranoid about even driving it, not knowing when it might happen again!

I bought my 2005 kia amanti in oct 2005. On four occasions when going from reverse to drive.....a hesitation took place and the car would not accelerate until the accelerator is pushed all the way down....then the car would accelerate at top speed. If this ever happened in traffic could cause injury or death. Mentioned this situation to the dealer and nothing can be down unless the "so called" hesitation happened at the time when it was in the shop.

Dt*: the contact stated while attempting to apply pressure to the accelerator pedal the vehicle hesitated. This occurred intermittently. The vehicle has been taken to the dealership three times for inspection. They were unable to duplicate the problem. The manufacturer was alerted.
