#133 of 144 Unintended Acceleration 2008 Santa Fe 4 WD by santafescared

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 uskeatscogeco.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.

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.
