Kia Amanti 2006 and earlier



  • I saw a post from 2008 describing my issue to a T. While driving at around 50 to 60 miles per hour, you slow down to around 40, you press the accelerator and at 40 to 43 miles per hour you get a shuttering or a vibration for 2 or so seconds until you are going faster than 43 then it goes away and all is normal.

    Another description is it is like running over the little warning speed bumps before an intersection.

    This is an intermittent condition and it does not trigger a check engine light. There is no rhyme or reason to it other than it occurs at about the same speed when it does happen.

    Could this be a computer issue? Does the computer need to be flashed?

    Any advice or assistance in determining what the cause is would be most appreciated.

    Yep, I am now having the same issue, which just started about five months ago, with 34,000 miles on my 2005 Amanti.

    It is just another item to emphasize as to why I would not buy another KIA vehicle.

    One day I may wake up and decide, forget the smooth ride and comfort, I want a vehicle that is reliable. At that point, KIA is history, permanently.

    I had Kia change out the fluid for the tranmittion. plus I made sure they put in the repair log I was having problems with it. so far I have not had any more problems with the car jerking.
    as for the computer problems I as having, kia replaced the electrial conetion box under the driver seat. It must have been where the short was because I have not had any problem since then. knock on wood. :)
  • Thanks for the info. I suppose it doesn't cost much to do a trany flush. That is the easiest thing to try.

    How much was the electrical box change?

    Did you have the same symptoms both buckhorn and I described?

    I spoke to my dealer about the transmission flush and he said it ran around $89. He stated that the fluid in the KIA was 'life time' fluid and should not require a change, unless an inspection found something wrong. He had no comment on the issue occuring between 40-45 MPH, other than the standard comment that they would have to check the vehicle. In this case, since it happens everytime, in the 40-45 MPH speed range, they could not say that it could not be duplicated. They would just charge to investigate. For me, my warranty is expired, so that would run into extra bucks. The question is if this is just an 'annoyance', or a pre-cursor for a larger problem.
  • Thanks for the update. At this point it is an annoyance but like you said, is it a precursor to a bigger problem.

    We have a lot of little issue with the vehicle. In fact we nicknamed the car Chuckie since we feel it is possessed.

    We have issues with the climate control and the mirror recall settings. The vibration problem is just one more in a growing list.

    We debate if it is worth while to get rid of it but who wants to buy a car that get 19 mpg average fuel economy.

    It does ride and look nice.

    The reason that I still have mine is simple, it is not practical to buy another vehicle at this time. Other than the issues that I have mentioned in the past, it is a great riding vehicle. The mileage is low, above 65 MPH. At 65 MPH, I get 25 MPG, at 70 MPH it drops down to 19-20 MPG, on level ground. Now with that, I look at new, smaller vehicles with EPA stickers stating 17-23 MPG, or 19-27 MPG. With the EPA sticker, those figures are 'maybe' figures, and are revolving around the 65 MPH range. Many of the cars are what I term as 'plastic' cars. You look inside and see obvious, and ugly, plast trim and parts all over. The cars are made 'lighter', for mileage purposes, which includes molded, 'no-bumper-bumpers'. If you get hit in the rear or front, you essentially have NO bumper for protection, and will be looking at major damage, and potential injury. With the number of trucks/SUV's running around on the road, it is like tossing dice. Personnaly, I do not like, and would not buy a small car. I like metal around me (my last car was a Lincoln Town Car, one of the old 'boat' series, all metal, hydraulic bumpers. I still drive a 1999 Buick Park Avenue, for the same reason. That car, with the V6 engine get 35 MPG, when doing 70-72 MPG. I have averaged 36-40 MPG, if doing 65 or lower. I plan on putting another engine in this car, when necessary. The key item for me is that a car is a losing investment, unless you keep it for a good while. There is a lot of money involved in purchasing, that could go into other areas. I would rather not make a bad investment worst, by trading it in at a loss, and saddling myself up with debt again, hoping that the next one had no 'issues'. I can handle an 'annonyance', versus a real safety problem, that occurs constantly, and makes you afraid to put the key in the ignition. I was that way earlier with this vehicle, when it was having the frequent sudden acceleration issues. I virtually did not drive it, as I did not feel it was safe. I drove my Park Avenue instead. This is why my Amanti is six years old, with 33,456 miles on it.

    This accident happened last July. I posted it on the Kia and reported it to the NTSA. I did find a lawyer on one of the posts that was representing a client who had over 200K in personal injury and is permanently disabled. My husband and I are going to do a video tape deposition in September for the case which will go to trial in Ohio in October. I will also forward him this site, in case he hasn't heard of it. Below is a description of our accident last summer.

    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 shubs, 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 totalled!

    There was certainly something wrong with that car. It had only 20,000 miles on it.
  • My husband and I had an acceleration accident where the car went from a stopped postion in park, he tried to put the car in reverse, and the squelled it rear tires, lurched forward and accelerated down the street. There was nothing he could do to stop the car: he tried standing on the brakes, turing the motor off, gearing down, pulling the emergency brake. The car just kept accelerating faster and faster. We live on a circle and he steered it around the turn, narrowingly missing people standing on the street, and then lost control of the car. The car took out two large tree shrubs, slammed into a garage, took out the main post in the garage, and hit the car parked in the garage. The car stopped and the air bags went off.

    So there is a case in Ohio where a driver had the same make and model and has 200K of personal injury and is permanently diabled. We are doing a video tape deposition for that case. Please read the post that I posted.

    I do not have names of individuals to send, but I will send a document that I compiled. I stopped adding items to it some time ago, but this by no means indicates that my problem was fully resolved. As I mentioned before, my vehicle still occasionally has an issue with the acceleration AND stopping. I will use the address that you gave and email it to you.
  • Sorry, folks, but we don't permit organizing lawsuits within the forums.

    Thank you Kirstie, I was not aware of that.

    our electrical box was under warrenty. it is under the driver side seat
  • I am sorry if you misunderstood. We are not organizing a lawsuit, I merely mentioned that there is a lawsuit pending for sudden acceleration problem with a 2006 Kia Amanti. The purpose of mentioning it, was to share information only.
  • i know you posted this back in 2008. you said there was a programming fix for Kia throttle position sensor.
  • is there any place where i can get more info about the pending lawsuit for sudden acceleration on the kia Amanti.

    I will make it easy and give you what I had copied into my KIA log book at the time:

    Mar. 14 16:05 I received a call from the local KIA service manager. He stated that a TSR was out from KIA, authorizing the computer reprogramming. He wanted to set an appointment up. I asked him if they were going to put it in writing this time and he said yes. I made an appointment for Tuesday, @8:30.
    Mar. 20 16:38 Took can to dealer. The following was written on the service order, “A customer requests that we reprogram the ECM as per TSB on Amanti.” “39110F26 ECU upgrade”. I will now drive it for a while and see what this upgrade has done.

    Now, as for the upgrade, it made my vehicle to be under better control, with the braking/acceleration issues happening much more infrequently. Does it still happen now, yes, but more on a rare aspect, and out of the blue. So did the fix make it so that the car is more reliable--yes. Did it totally eliminate the problem--no.
  • Thanks so much for replying back to me.
  • Hi,

    The name of the lawyer that has the lawsuit against Kia is Charles Bendig out of Columbus Ohio. If you email me at I will forward his email address to you.
  • I had the same problem and took it to the local dealer who admitted it is a known issue .
    Dealer replaced spark plugs, spark plug wires and coil packs and it has not had the problem since.
    I have gone back to Kia Corporate to ask for a free repair and a request for a TSB and a recall. Cost was almost $900. I did file two federal complaints with NHTSA and the Center for Auto Safety.
    Never buy a Kia or Hyundai. Kia is now partially owned(51%) by Hyundai. I asked for the used parts and the coil packs were for Kia and Hyundai.
    I wonder how much of a Kia is really Hyundai (like a Lincoln or Mercury is really a Ford).

    Before taking it to the dealer I had a friend drive it on the highway (with myself in the passenger seat)and had no problem until starting up again after filling up with gas when it accelerated with no gas depressed. No wreck due to their foot already on the brake. My friend admitted the problem as did the dealer I'd name the dealer but I do not know if the moderators will allow me to name the dealer or my city. e-mail me at and I'll give you the name of my local deal :mad: :mad: :mad: :cry: er.
