    Hi
    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

    This appears to be another issue not related to sudden unintended acceleration, but I have now experienced several times during road trips when I have activated the passing gear--the acelerator pulls down and stays totally depressed to the floor board and will not release with foot pressure with out a lot of braking and foot banging! My vehicle is a 2008 Santa Fe, 6-cyl. awd. I'm lucky that this has not caused an accident or death--but it is a harrowing experienced to have the vehicle taking over at FULL THROTTLE not in my control!
    Have others experienced this condition? Dealer says nothing appears or recorded to confirm this issue??

    I also experienced Sudden unintended acceleration in my 2008 SanteFe 45K mi. I was in slow traffic creeping along when the engine reved and the car accelerated very quickly. Brakes weren't enough to stop it. I crashed into the car ahead of me. I am terrified. I took it to the Dealer and like everyone else who has posted, they said they couldn't find anything wrong with the car. On another occassion, my husband said he felt the pedal sticking.

    My 2004 Santa Fe has done the same thing 2x ! Nothing that could be replicated at the dealer so of course nothing can be done. THANK GOD I was able to throw it into neutral and slam the breaks and stop!

    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!!!

    On July 31,2012 I was going up a hill going about 3 miles an hour in order to make a right hand turn into a parking space for the laundry room building across from my Mobile home. Had to park there due to trash collection and can not put trash cans away with vehicles in the carport.

    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.
  • To those who have unattended acceleration.

    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
  • I am still visibly upset about the unintended acceleration of my new 2012 Hyundai Santa Fe. I was also pulling into a parking spot making a right turn when all of a sudden the car accelerated full trottle and I ran over two bushes and knocked down a black iron fence and stopped by pushing very hard on the brake when I was on pedestrian side walk. Luckily I did not hit a pedestrian. It was so scary I went to the dealer and the delaer stated that the computer did not find anything wrong with the car. I am scared to drive the car. It may happen again. I did call the NTHSA to report this and I plan to go to another dealer to see if they can help find out why this happened.

    Just had my 2007 Santa Fe towed to the local dealer for the exact same problem. Lucky for me I was on the freeway when all of a sudden the throttle went to the floor and the car began to accelerate. when I couldn't get it to cease accelerating I place the transmission in neutral and allowed it to coast while I kicked at the throttle peddle without success. Once I came to a complete stop (on a small shoulder next a very busy off ramp) I was able to pry my foot under the peddle and bring it back.

    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.
  • I too live in Canada, in Peterborough Ontario. Last Friday night, October 19, 2012 I was traveling a County road to go and pick up my dog from the breeders. My 23 year old daughter was with me. The unintended acceleration happened when I made a right signal change to veer to the right on a ramp and then when I accelerated to get back up to driving speed I could feel the foot petal leave my foot, accelerating quickly. It felt like cruise was on. I pushed the cruise on and off. Nope it wasn't the cruise. I thought maybe the floor mat was stuck, I tried to tap the pedal with my foot and I couldn't even reach it. It had been pulled so far forward I couldn't even reach it. My daughter looked over and she could see the pedal at the far front of car and no floor mat was pushing it nor was my foot. It was just accelerating by it self!???
    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

  • Hi Again

    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.

    If people are still having a problem with this (fortunately I have not experienced this with my 2012 SF), and the NHTA is not responding - might I suggest someone start a petition?

    Especially in light of the recent $1+ billion Toyota settlement, perhaps that can be used as leverage against Hyundai.
  • Hi - can anyone please let me know where the facebook site (Don't buy Hyundai) is and where the Hyundai Santa Fe video is. I desperately need your help.
  • stannardsstannards Posts: 16
    Hi - we started the FB page - although it doesn't say that much - we sold our car after getting it repaired and were very very upset with Hyundai ignoring the problem. It is now nearly four years since our incident and I have been amazed at just how frequently the problem is occurring. If you send me your FB or email details I can probably give you the link that way. We took video of the car after the problem - is that what you were referring to? If so I can check with my husband for it, but I think he put it on You Tube originally so it may still be there.

    Just wondered if you had any more to report on this?

    Our story was on WFAA TV in Dallas Ft. Worth. If you have had this problem, please contact a television station in your city and ask them to help you by exposing your issue with Hyundai.

    Just had the entire computer in the car replaced after mine did the same thing. Last year they spent a week and replaced various things because the clutch kept going out, one time stranding my wife and 1-year-old in traffic. It's a 2007; my wife's 2003 crv with twice the mileage is a much more dependable vehicle.

    An update to my original post.

    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.

    My wife and I just experienced our third incident. About a month ago I had the Santa Fe in for the 30000 mile service. I have all service done at the dealership. After the service I was taking an exit to home. The car was at full temp after 40 miles of interstate driving. As I disengaged the cruise and slowed down the accelerator stayed down at about 35 mph. I put on the brake and stopped and pulled up on the accelerator with my foot.

    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.
  • Today I experienced a full throttle acceleration incident with my 2002 Hyundai Santa Fe LX. I was driving along at 30 MPH with the gas pedal normally pressed and the car felt like cruise control was turned on (it wasn't). I applied the brakes and the throttle kept climbing, so I pulled over and put it in neutral. The throttle was fully open at this point so I turned the engine off. With repeated starts, the engine immediately went into full throttle while in neutral. The gas pedal wasn't stuck.

    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

    I stumbled on this by accident but have to share my experience. I was turning right onto a 2 lane road when my Santa Fe began accelerating and the RPMs were in the red. Braking didn't work, I popped it in neutral and that didn't work either, still accelerating. I turned it off and coasted into a parking lot. I tried re starting a few times and each time the tachometer maxed out so I called a tow truck. My mechanic told me that the crimped end of the cruise control cable had broken allowing the cable to extend fully and open the throttle all the way.
    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!

    Yes meg88, that's exactly what happened to my Santa Fe 2002. It's a defective cruise control cable with the end cap falling off the tubing. Cable looks similar to the break cable on a 10 speed bike, but thicker. The mechanic replaced it with a new cruise control cable.

    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.

    I loved, loved, loved my 2008 Hyundai Santa Fe, but this afternoon that all changed. I was on the highway going about 55, pressed the accelerator to pass another car at 60, and the car quickly accelerated to 70, I braked and nothing happened, and speedometer was hitting 80 when I put the car into neutral and pulled to the side of the road. Even in neutral the car was revving at 70,000 rpms. Turned the car off. Took a breath. Turned the car back on and it revved again. Put my foot under the accelerator and was able to nudge it back towards me, which stopped the revving. It was clear to me then that the accelerator had gotten "stuck" - but not under a mat - just stuck. Drove very carefully back to my hotel and will be taking it into the dealership to be looked at. But after reading other posts, I have grave doubts that the dealership can permanently fix the problem. It makes me sad, because I was planning to drive this car for at least 150,000 miles. Not any more. And I will be logging this incident with the National Highway Safety folks.

  • Hi I am so sorry this happened to you . It happened to me with my elderly mother in the car. I was able to avoid a collision and went over a curb and it finally stopped. I got a lawyer and Hyundai said everything was fine. It is so frustrating because when this happened the car was brand new and now it has been 11 months since the incident. They sent someone from Hyundai California to check out the car and they said everything is fine. I am wondering if they fixed the TPS or cruise control. The car has not had any problems since the original sudden acceleration. There are too many people having this problem and is NOT due to floor mats!!!
  • Happened in 2007/8 with my 2003 Santa Fe and to my teenage son at a Stop sign. Thank goodness nobody was hurt and our small town garage was just around the corner. First the throttle body was cleaned and it worked well for a few weeks. Then the unasked acceleration happened to me. Another visit with the local mechanic who ordered up a new throttle body and replaced it quickly with no big dealership costs. I think it was about a $150 job. Never happened again.
  • 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.
