I have had the same problem with my 2010 Sante Fe. I didn't have the problem until they reprogramed my car on a recall. I took it back in and they reinstalled the original program and it seemed to solve the problem...for a while. It did it twice in the last six months even with the reprograming. It is a very potentially dangerous situation that I am sure Hyundai is becoming aware but seems not to be addressing. I hope that they find the culprit and offer a remedy before someone gets hurt! I, at first, thought it was only turning left too but found it not to be necessarily so...I, like others, am just at the mercy of documenting...help us out, Hyundai!!!

About four months ago I brought in my 2010 Santa Fe and as usual they could not find anything wrong. The head mechanic said that he did something with the program (I guess just to try anything). The problem has not occurred since then (started at 20,000 miles, now at 24,000 miles). I too brought it in for a recall--maybe at that time they did to my vehicle what they did to yours--and maybe the mechanic then also eventually put the old program back--who knows? It seems everybody is without a clue as to why this happened or happens. Thanks for your feedback.

Several times in the past few months my 2005 Hyundai Santa Fe V6 2wd has shown a great surge, usually after starting. the only way I could control this was my slamming non the breaks. It has happened in drive and reverse.

A similar incident has happened to me. I own a 2011 Santa Fe V6 2WD and on the 27th January I was coasting into a convenience store applying light breaking pressure coming to a stop. There was sudden uncalled surge in engine revs and the Santa Fe leaped forward and it took maximum brake pressure to limit the forward momentum. Massive braking pressure and shifting from drive to neutral let the car back off the block back to level. Incidentally, one of those concrete was placed in the parking space, to protect the store-front, the Santa Fe climbed the concrete block. Apart from my heart rate leap stressing me, there was substantial damage to the front bumper and power steering.
Took the car to the dealership they said there were no fault diagnostics. I lost all power steering assist and there was no indication of power steering fluid loss. The service manager said " . . there is nothing that would cause this > ." implying it was my fault. There is no way that I could apply brake and accelerator pressure concurrently.
Since December 2011 we have been experiencing jumps when the starting the car, gear shift in park and brake pressure applied.
THIS IS A SERIOUS SAFETY ISSUE THAT HYUNDAI NEEDS TO ADDRESS BEFORE SOMEONE DIES.

I also own a 2011 Hyundai Santa Fe V6 2WD. This "sudden unintended accelerator surge" happened to me twice. The first incident happened on December 20,2011. This was my first time using the car that morning. I turned on the engine and let the motor warm up for about a minute. Then I proceeded down the road of my developement at around 15 to 20 miles an hour until I slowed down for a stop sign after driving about a 100 yards. At that time my foot transferred from the gas pedal to the brake pedal and the motor suddenly raced out of control. I was able to slam with all my weight on the brake pedal and shift the gear into neutral and turn off the motor. My wife drove with me and needless to say, we were scared to death. After composing myself, I turned the engine back on and thank God I did not experience the "sudden accelerastionon", so I drove back to my house and called Hyundai Roadside assitance who had my car towed to the Hyunder dealershipn where I bought the car. The Hyundai service department could not find anything wrong with my car and told me I probably put my foot on the accelerator by mistake. I 'm 100 % sure I didnot put my foot on the accelerator. So, reluctantly, I accepted the car back from the service department and ran the car daily until the exact same incident happened leaving my house in the morning again on February 6, 2012. As of this writing the car has been at that Hyundai dealership for a few days. On February 7,2012 he service manager again told me after all their testing they still could not find anything wrong even after this second incident. . I did call Hyundai Corporate offices and they are now investigating the incidents and said they would be in contact with the Hyundai service department. There is definetely some defect in the accelerator that Hyundai cannot find as of this writing.. Very scary situation for me and possibly all 2011 Hyundai Sante car owners. If you ahve a similar experience please let me know.

I too have had an issue with sudden acceleration surges with my 2005 Hyundai Santa Fe. My engine light finally came on, after taking it to a mechanic several times with the issue, only to have no real reason for the issue to occur. After the check engine light came on (this past Saturday), I took my car to Advanced auto parts to have it checked out. They told me the issue was P0121 which is Throttle Position Sensor/Switch "A" Circuit Range/Performance. I contacted my mechanic who told me it would cost approx. $250 to have the sensor replaced. I'm willing to pay the $250, with fingers crossed that it works, instead of purchasing a new car. If this replacement does not work, I will never buy or recommend a Hyundai to anyone I know. This is a serious issue that Hyundai needs to address before someone seriously gets hurt. I am appauled that they have not taken the proper actions to address this issue before it really gets out of hand. I will let you all know if the replacement of the sensor works.
#118 of 151 Unintented acceleration and hesitation
Feb 19, 2012 (8:18 am)
I am so glad I am not the only one. I own a 2005 Santa Fe, that was working just fine until last week. I was pulling onto a busy highway, and all of a sudden the vehicle hesitated quite substantially. I thought because it was so busy the car behind me was going to crash right into my back end. Then I was driving along later that day it was constantly accelerating. When I stopped the car, and had the break on, it was reving really high, and I was afraid to take my foot off the break. The check engine light came on, and because I was working I couldn't get it into a garage right away, so thought I would later that afternoon. After I shut down the vehicle, the check engine light did not come back on...but the problem is still happening almost everyday for a smaller amount of time. I am afraid to drive it anywhere right now, and can't go without it for very long. Please let us know if the sensor you got replaced works out for you!

Interesting post, I tought I was alone having this problem until I found this post just now; Thanks everyone for your comments, this is unbelievable.
I live in Canada and have a SF 2005 - 3.5L AWD which I bought new in 05 which now has 251,000 km on it. I to have had SUA over the years every once in a while and ever since it was new. I noticed that most of the time this happens is when I come to a full stop then start rolling again; slightly depressing the gas pedal; within a fraction of a second; the vehicle blasts off (heads fly backwards) as if I had put the gas pedal to the floor for a second or so; then it quickly resumes back to normal. Will be days sometimes weeks before it does it again and sometime the same day. Its very sporadic with no real patterns as to when it occurs although seams a little more frequent lately. I mostly do highway driving and use the cruise control everyday. I did not have any close call for say although from reading this awesome post, I will keep a close eye on this issue and will order and change the throttle position sensor and inspect the cruise control cable and it's assembly.
Also, if this can help, way back I had noticed that occasionally when I filled up with gas and then drove off, within a couple hundred feet the motor would kind of die and hesitate dramatically before taking off similar to an SUA; after some reading in other post (way back), some had reported similar issues with other car brands and suggested the following, when filling up with gas, tighten the gas cap all the way until you hear several clicks (as to do with proper venting our pressure balance within the gas tank) which I tried and did not really work; my gas cap needs a key to open it therefore, instead I do the opposite, I tight the gas cap and back it off to hear a few clicks and never had this issue ever since I started doing this (Note that I've also tried leaving the cap loose although did not work; perhaps one could also try another cap). This may or may not be associated with the SUA problem, who knows, I do not have severe SUA, although it still happens from time to time for a fraction or a second or so and goes back to normal immediately after (unlike some post I've read in here and which I deeply sympathize with). Perhaps another thing to try which cost nothing and can't hurt re: gas cap (as mentioned herein); seems like pressure or back pressure within the gas tank needs some kind of balance. Give it try who knows, it may reduce the problem. I do like my Santa Fe, found it hard on gas although, don't think I'll buy another one. Hoping this helps somewhat. I'll look deeper in the SUA and report back if I find some kind of possible cure. In the mean time drive this beast carefully. Thanks

Just wondered if the replacement of the sensor worked. My 2009 Hyundai Santa Fe. It lost complete throttle control and would only idle. Got to the side of the road & turned it off and unhooked the battery cable. This reset the electronics in the car( clock, radio, etc) and with it the throttle sensors. Was able to restart and it drove perfectly. We had been having hesitation issues for a couple of months and now it drives smoothly. Just don't know how long it will last though.
