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.

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.
