The last time was two weeks ago. My wife was driving the car in a parking lot. She stopped at a parking lot intersection and it happened and it only happened for a few seconds and then it stopped and she turned right and then once again stopped while someone walked across the road and it happened once again. It only lasted a few seconds. She then turned right to go into a parking space. It once again accelerated but this time the car didn't stop until it hit the car parked in the next parking spot and then it pushed that car into the next parked car. Damage was done to both parked cars and also tore up my bumper and a fog light. Thank goodness no one was walking in front of the car or between the two parked cars.
The car has now been at the dealership for almost two weeks and they of course say they can't find anything wrong with it.
Don't know what I am supposed to do now. I am scared to drive the car for fear of it happening again and maybe injuring myself or someone else. This car could very easily surge while at a busy intersection and it could be pushed out into oncoming traffic causing several injuries. Does anyone have any ideas?
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.
THANKS!!!
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

I will be contacting local media in Edmonton when I get home to bring this matter to light. It's a matter of safety to not only the occupants of the vehicle but other drivers on the road (or pedestrians for that matter).
The vehicle accelerated to the floor and and would would not slow down, at first I was braking, but it only slowed the vehicle down a little. We went through an intersection (luckily the light was green) at the point I put the vehicle in neutral and braked to the side of the road. This was not a matter of the floor mat pressing on the gas as that was the first thing I checked, the gas pedal was stuck to the floor and there was nothing I could do about it.
I also live in Canada. I reported this to Transport Canada and a Regional Official, an Engineer, followed up and asked some interesting questions. He actually came and visited and examined peddle separation and height checked. We visited place where the incident happened. One point of note there does not seem to be a good deal of diagnosis sensing on Hyundai software drive-by-wire, neither is there braking override of throttle position. Do report this to TC it's a serious safety issue. The web site is https://wwwapps.tc.gc.ca/Saf-Sec-Sur/7/PCDB-BDPP/Index.aspx
Have others experienced this condition? Dealer says nothing appears or recorded to confirm this issue??
I've also LOST power when stopped at a light and when I went to go had nothing but spitting and choking. Pulled over and let it run itself out and it never happened again. I swear I got a Friday 4:30 vehicle!!!
Suddenly my Santa Fe took off like a bullet, jumping the cement parking barrier and crashing onto the building. The front of the building, including window and door crashed down on my hood. When I finally stopped I had taken out the building, damaged a washer and dryer. The engine was still running and I had my left foot on the emergency brake and my right foot on the brake.
My vehicle was in the shop for 9 days and I just got it back.
Am I nervous to drive this vehicle? Yes
Hyundai has a moral obligation to compensate anyone who has had this problem.
Next time this happens someone could get injured or killed and I do not want the responsibility of that.
Please call NHTSA at 1-888-327-4236 to speak to a representative who will take your complaint.
My 2007 Hyundai Santa Fe had unattended acceleration on July 31, 2012. I called and reported it to the customer service gentleman at NTHSA. He took my complaint.
The only way to get this dangerous problem resolved is to contact NHTSA. They will post it.
I have also sent to Hyundai Motors America my accident information and am waiting for a reply,.
Thanks, Mary
While I had it running in neutral I floored the accelerator and it did it again 2 more times. Once I worked up enough courage, I limped it home and called the dealer. The service writer informed me that Hyundai states that this is impossible to occur. I plan on having a more in depth discussion with them in the morning after they look at it.
I am not familiar with the electronic acceleration system on this car, but it sure appeared as if something like the cruise control was forcing the peddle down. Perhaps someone with more technical expertise can explain it.
After reading other's experiences I have a pretty good feeling how things will go down at the dealer. I will post the outcome.
P.S. Here is a curious note for the techs out there. I noticed that the engine got up to over 6,500 RPM when it was self accelerating. However when I was attempting to duplicate it, it would only get up to 5,500 RPM. Maybe I just wasn't willing to let it go there.
At 160 kmh I dropped into neutral and braked to the shoulder. While sitting on the shoulder we could smell plastic burning and the cab was beginning to fill with smoke, the gauge was showing 7000 rpm, the sound of the engine was deafening, when the rpm's reached 8000 I decided that the vehicle was going to blow up and I moved the shift into park and it was like I had turned a switch, rpm's started falling, speed on Odometer was falling, smoke in cab was lessening and in approx 15 seconds everything was back to normal and the foot pedal had returned to where I could reach it!!
I called the dealership and had it towed. This morning they called and said nothing showed up on their computer but the mechanic thought that it was probably the floor mats because I had 2 and they were up on the gas pedal! I reiterated my story once again to him and he told me he couldn't do anything because nothing showed up on their computer. He gave me the name of Hyundai Head Office which I will be calling and I will be calling Transport Canada. After hearing all the horror stories on this forum, I'm afraid to drive it!
I think we should form a class action law suit so Hyundai takes us seriously. IF you are interested, I can be reached at uskeats@cogeco.ca

I just wanted to give you all an update. I have not driven my Santa Fe since 9/24/12. I have gotten an attorney and the legal dept is talking with my attorney. I had to take pictures and fill out a long form for Hyundai and send it back with a letter from my attorney. Then I called the dealership and they had to complete all these forms on my car. The dealer told me that once legal gets involved they can't say anything.

Especially in light of the recent $1+ billion Toyota settlement, perhaps that can be used as leverage against Hyundai.

Since the incident we, I and my better half, decided not to use cruise control on the Santa Fe. Since then February 2012 we have not had an occurrence of the "unintended" acceleration. It would be interesting to see if each Santa Fe owner had used or if the vehicle was equipped with cruise control, I suspect this is so.
There are a few reports of changes to mechanical components that may have stopped the problem or at least eased the owners mind. Now after a year of considering my situation and this forum, I'm of the opinion the problem is certainly not of the mechanical variety. The Santa Fe has a fairly comprehensive set of software "drive-by-wire" that is at the heart of all operational conditioning. This software is unsafe for several reasons;
1. There is no fail safe braking override of throttle position, which should be mandatory in all software controlled services:
2. The fault diagnosis is obviously inadequate in all documented cases in this forum the service guys say there is no indication of failure;
I'm of the opinion, as a 20 year veteran designer and programmer of real-time software and ruminating this failure characteristic, the failure modes have been inadequately analyzed and programmed by Hyundai software development teams. Ineffective failure mode design and analysis of operational situations. For example . . does a sudden massive increase in open throttle make sense . . and in conjunction with brake pressure makes even less sense. Yes, most inexperience programmers only consider a discrete event not multiple events when dealing with their failure mode and recovery.
Software is not well understood by the general public and its easy to blame the driver or a mechanical gadget. Also its easy to modify the software on your vehicle and you would never know about it. Ever noticed that pilots get blamed more frequently that seems reasonable in aircraft incidents, as PILOT ERROR. Similar with complex cars, DRIVER ERROR.
The next morning my wife took the car on the short commute to work and the accelerator stuck again at 35. She was frightened and the car stayed at high RPM and stayed that way until she turned it off.
I went to the dealership and told them of the incident and they checked it over and we went through the list of items. The floor mats, etc. They make some adjustments electronically and the car was fine. They could not find the cause and though courteous they thought it was just a high idle and or the floor mat. I have been driving for 40 years, I know what happened.
Today, April 14, 2013 at 2:00 p.m. with the outside temp at 40 degrees fahrenheit the most frightening incident to date happened. Again we were on the interstate heading home from Madison with the cruise engaged I accelerated to pass vehicles in the center lane. We had driven around Madison for a time and had been on the interstate for 30 minutes. When I accelerated the Santa Fe kept going faster and the pedal went to the floor. The brake did not help and we kept accelerating. Traffic was heavy and we were increasing speed to almost 85 when I put the car in neuteral and turned off the ignition. I then restarted the vehicle at about 65 and the gas pedal went back to its original possition. We were about 15 minutes from home. I turned off the cruise and the car was operating normally when just as we turned down our street the accelerator stuck at about 20. This time I put on the brake and it returned to normal.
It is not a high idle, it is not the floor mat and my wife and I were scared to death. I do not want my wife to drive the vehicle any more until this problem is fixed. I am afraid that again the dealer will not be able to replicate the problem and we will need to update our will. From your experiences however I am concerned that I will be courteously ignored.
I've had it towed to an independent shop so they can identify the problem. Tomorrow I should have answers. I've filed a complaint with NHTSA and there are many full throttle complaints listed there: https://www-odi.nhtsa.dot.gov/ivoq/
Here's a news report on a newer Santa Fe: http://www.wfaa.com/news/consumer/More-Hyundai-owners-step-forward-claiming-sudd- en-acceleration-problems--193732371.html

This was 2008 and I had just left a job after 20 years and was going back to school. In fact, I was on my way to my first day at an externship when this happened. Showed up late the first day in a tow truck, great impression! What I'm saying is I never pursued this as a possible common problem that I should report, I was too busy. Now I wish I had reported it. I figured that I had just gotten one of those random, defective parts.
I loved my '02 Santa Fe and continued to drive it without the cruise control until I traded it on a new 2012 Santa Fe last year. That was honestly the only problem I ever had with it until the A/C started leaking last year. I must say that the quality of the 2002 was much better than that of my 2012. But I still love it!

Acceleration parts that break shouldn't cause accidents, especially when you can establish a pattern across model years. Hyundai might want to do a voluntary recall.
Hello, I own Santa Fe 3.5 V6 2012 current with 18000km, my car was trying to accelerate--despite my foot being on the brake. It was also making a loud revving sound, my car does not have cruise control as most of the comments I have seen here. does any one knows the solution for this problem.
We have experienced unintended sudden acceleration in our 2009 Sante Fe 3.3 liter 6 cylinder automatic on 3 different occasions in the last 18 months. Each time we were accelerating . Once it occurred when we moved from one speed limit to another ( 50 kms/hr to 60 kms/hr ): once when passing and once when moving from a ramp to highway speed. The floor mats were not near the accelerator and cruise control was not engaged. Hyundai refuses to do anything because their technician has to experience it personally. My wife and daughter refuse to drive or ride in it. Our insurance company has never heard of such a situation in Hyundais .We are exploring our options. Safety5
I have owned my 2006 Hyundai Santa Fe for 3 1/2 years. A few months ago, I was slowing down as I approached a light that was changing to red. My foot was on the brake when the engine began to rev and I was unable to slow it down with the brake. Luckily, no other vehicle was at the intersection and I went through the red light. The engine did slow down on its own in a few seconds, and I was safe. I thought about documenting the incident but failed to do so, then forgot about it.
On Friday, March 28, 2014, I was stopped at intersection with my foot on the when the engine began to rev. I pushed harder on the brake, the engine decelerated, but then immediately revved again, this time the car began moving forward into the path of an oncoming vehicle. I steered right to avoid a collision into my driver's door, but we collided anyway. My Santa Fe traveled about a car length onto the grass, the engine revving ended, and I stopped after plowing down a lightweight fence. I still had my foot on the brake, and I turned off the engine then removed the key.
The other vehicle stopped off road before the next intersection. That driver was taken to the hospital via ambulance, and his vehicle suffered extensive damage. My damage was to the left side from the wheel forward, the bumper was loose, and the hood bowed up. Based on my statement to the Florida Highway Patrol Trooper who investigated the crash, I was not ticketed in the accident/
The insurance adjuster has determined that the other vehicle was a total loss, while mine is going to cost over $7,000 to repair.
I called Hyundai and opened a case with them. I also called the National Highway Transportation Safety Agency and entered a complaint there. I am now contacting an attorney. I intend to make my voice heard. This accident could have resulted in death of one or both drivers. As soon as the repairs needed to get my car on the road again, I intend to go straight to the Hyundai dealership and request an inspection and investigation into the cause. I will not let this rest.
