Count me in also

I have a 2011 EX, four banger, and tried to do a u-turn in front of oncoming traffic and had a WHEW moment when I hit the accelerator and the car hesitated at the wrong time. This was not fun and KIA needs to wake up! The local service manager said I could make an appointment and check it out...I will do that. Secondly, he said it may be bad gas and make recommendations for a better quality gas company. Also recommended a fuel additive called Petro sp?? that they sell there. This isn't a good enough response in my opinion if others are having issues. I would hope a fix or recall is on the way. My brother has the AWD 6 cyl Sorrento and has the same problem.
KIA, take a lesson from the fiasco Toyota and don't wait till someone gets hurt, and loose many customers. Jus sayin

Throttle "Disengaged", going into LIMP mode

Happened to us yesterday.

Could this be the same thing?

Did you read all the post in this thread????? If you did, you would have read that the op had his foot on the brake and the gas pedal at the same time, hence the reason it would not go faster is his foot was ALSO on the brake.

next time you plan to make a U-turn or go up a slippery or dusty gravel hill, make sure to turn off the Sippery Road assist, to prevent the loss of power.

I've had time many times already, and the solution was to turn that feature off, it causes more problem that what it tries to prevent.

It's good advice to leave more space between cars.

The same thing would happen with other cars. With the additional weight of an SUV the anti-slip kicks in at different variables.

Now that winter is coming be forewarned that abs may also give you problems...it's designed to keep you in control and it usually increases stopping distance in situations where it activates.

Best advice mentioned in another thread is to try out features so you know what to expect when the feature engages. This is the same advice as for any other car.

AMEN BB6886!!! You could be right? I have experienced this traction control (ESC/ESP) "nanny" almost killing me! I believe it's also tied into the "DBC" downhill brake control.

Traction control is always "On" by default, and if it detects any kind of unsafe maneuver, it will engage. Only the nanny (robot) knows what it considers an unsafe maneuver? In essence then, it drives your vehicle, not you! Heaven forbid it goes haywire

The Scenario,
My new, & new to me, 2005 Tucson LX V6 AWD with the "new" ESC system. Making a U-turn on a busy blacktop road with gravel on both shoulders, in the rain. I catch a break, but it has to be fast, I hit the gas lightly in drive to make the turn on wet gravel, the Tuc goes 5mph? I feed more gas, the Tuc goes 5mph?? I floor it, the Tuc goes 5mph??? I'm 1/2 way into the turn, with traffic bearing down from both ways in the rain, but on blacktop now,,, still "pedal to the metal" the Tuc goes 5mph!!!? I end up making the turn in horror , only to end up on the wet gravel on the other side, with the Tuc still going 5mph!!! I finally finish the turn, & back on blacktop about 1/4 mile before the Tuc started to pick up speed, still "pedal to the metal" needless to say my wife, & I were terrified! I thought there was something wrong with the car? because ESC was all new to me, and I didn't like it one Bit once I figured it all out! By the way, after 50yrs behind the wheel, I know how to drive on wet gravel, but the traction nanny wouldn't let me. Beware, the traction nanny "robot"

ESC is discussed starting on page 5-32 in the Sorento owners manual, 2012. There is a button to turn ESC on and off. Also, when it is on, the ESC light will come on when it engages so you'll know if it comes on.

Came on for me once in a slippery condition and I saw the ESC light come on. Surprised me, but it made sense when it happened.

Don't know about Hyundai Tucson but hopefully it's the same and can be turned off and on as needed. It's like the attached picture.

Yes, it is the same on the Tucson, but once the light comes on, it has already done it's thing! ESC is ALWAYS ON by default when you turn on the ignition. I always turn it off now, unless weather condions are really bad, and notice I also gain a couple more mpg.

Basically it is like a computer controlled gyroscopic joystick that automatically adjusts the brakes, & throttle, to always keep the vehicle on the straight, & level, but it cannot think for itself like a human. In some situations, it can be dangerous because by the time it takes for you to realize it's working (what's happening? my car is acting strange!?) it's too late to turn it off

I believe ther might have been a TSB from Kia concerning reprograming the CPU. May want to see if the dealer is aware of any KIA CPU reprograming for your year, mfg date and model.

 

[VIM]

In reading the earlier posts and then the recent ones, they seem to be different to me.

The original ones had different symptoms than a stability control issue.

Also, since they are so old, there may have been TSBs to address those. I would say the recent posts should have their own thread about stability control.

Would be good if the original posters that experienced the problem report what happened.

 

[mITKI]

Samuel , I think you are fully right to adress your problem to the top .

This phenomenon occured one time while I was merging a highway
at the end of a curve , I was full throttle when the car stopped to run ---I then
quit the gas pedal , missed my merge , then re-applied gas and everything
came back normal . Never happened again ...

My Sori have now 75,000 kms , this incident dated from around 5,000 kms ,
bought it march 2010.

Keep us informed and keep faith.

Known Issue with Fix Available

I just came from my dealer's service center. I went in for the Brake light recall, and there was also one for the power windows. I explained the issue with the acceleration problem discussed here, and while the check in service rep was initially a little dismissive, the mechanic let him know of a new firmware upgrade that just came out. It adjusts for pressures and timing within the transmission. It has a 800-1000mi. run in time, but is meant to address the issue. Might not be an instant fix but at least they're finally addressing the issue. Further info for you to reference, BUT THIS MY JUST BE FROM MY GARAGE. TCM UPGRADE 999 95440F24 TCM UPGRADE FC: C40 PART#: 391083C010

Hope this helps someone else.

I've experienced similar situations. Go to accelerate, with no power. I don't use left foot. I do notice the flashing ESC picture on the display while it happens, but this is more of a safety concern that a computer can't comprehend, as there is oncoming traffic that you are trying to avoid. It doesn't help you avoid this traffic when the vehicle fails to accelerate and just virtually crawls slowly ahead. It has happened in winter as well as on dry pavement. And from what i remember, it was always while turning.

 

[VTCOLD]

Ditto!

I have been experiencing a similar issue, except that I am lucky (in a way), since it happens when I am not running the car. Car sits in the driveway for a couple of days after running without any issues. I get in the car and no acceleration at all. Can idle my way around but that`s it. Will turn it off, restart it, put my foot on the gas and it idles, even if I floor it. Put it in D, it idles. Took 3 tries to have it go up the tow truck ramp; not enough power.

Was at the dealer last week and they said they had fixed it by reprogramming the computer. Used the car for 3 days after that without any issues. Left it parked over the weekend and this morning, had to call the tow truck as the car would not accelerate at all. Dealer is very apologetic and is looking into it! Say they have never encountered this issue.

I am not driving the thing with my 2 feet, I`m not even making it out of my driveway. Help please!
