My vehicle is a 2012 Hyundai Santa Fe with 131,000 miles. I was driving on the highway traveling about 65 mph and lost power steering, power breaks, and speed control. My car began to slow and would not accelerate and was difficult to steer. Fortunately I had enough power/speed still to get over into the breakdown lane. I was able to use my directionals and hazard lights once on the side of the road. I shut off the car and attempted to start it again several times without success. The check engine light was on, as was the oil light and battery light. There was no discernible warning that would have indicated an impending engine failure. I had already driven 75 miles of my trip and it simply stopped running. In the middle of the highway! the cause of the problem is unknown to me and currently unknown to my mechanic. I had to have my car towed 50 miles to the mechanic. Getting it to a dealer would have been even father.

10 Vehicle Speed Control problem

Failure Date: 12/15/2013

Please investigate the Hyundai line of cars. I was driving this car that I owned. I had just driven 140 miles, and I was on city streets making my way to the inlaws. I stopped at a stop sign and as I accelerated and proceeded to make a right turn on to another city street, the engine completely died. I noticed it when my power steering locked up, I had no brakes and I was headed right toward a home's front door. I was able to stop the car when it hit the curb dead on. I then put the car in to park and turned the car back on and it fired up right away. I really believe that Hyundai has the same problem as gm. There was nothing wrong with the car after that and I could not duplicate the incident. I traded the car in a few days later because I refuse to drive it. If you google the problem, I was able to trace it back at least 11 years. How can you trust a car that where the engine will just turn off sporadically. Dealership claims "they've never heard of such a thing. . . " lies. The know about it, they just haven't done anything about it. I seriously think there needs to be an investigation in to this vehicle. I saw stories of peoples Hyundais dying on the freeway. They could have been killed. One lady said that she was told next time it happens to leave the car as is and they will tow it and check it out. They towed it after it died and nothing. That's what leads to me believe that in this vehicle, the key can also become disengaged while driving. Similar if not exactly to the problems with the gm. I beg of you to investigate!!!.

11 Vehicle Speed Control problem

Failure Date: 09/12/2013

1st incident occurred while driving approximately 20 mph in morning rush hour traffic. The rpms dropped to idle and the engine malfunction light came on. The accelerator would not respond to increase speed or rmps. I rolled to the shoulder of the road and turned off the car. When I re-started it, the engine malfunction light was still on but I was able to drive off the road and to the dealer. Same thing happened two additional times on my way to the dealer. Dealer advised that a computer update was needed. I was told the repair was made. Next morning I drove approximately 5 miles and the same issue happened, except this time I was travelling 55 mph. Re-started the car and was able to drive back to the dealer. I am now being told that the throttle body is being replaced as per instructions from Hyundai and that I was not the only person having this repeat problem.

12 Vehicle Speed Control problem

Failure Date: 09/09/2013

We started the vehicle and the check engine light came on. We then checked the manual and it stated there might be an emissions problem so we checked to make sure the gas cap was tight. We started it again, but the light came on again. We backed up the car, but it would barely move. We called the dealership to have it towed and checked. The dealer called us the next day and said someone cut the wires above the accelerator pedal. That claim was suspicious because the vehicle is locked inside the garage and our house has a security system and a large dog. We also had 6 family member staying with us. Opening the garage door would have woke someone up. Also, the vehicles outside the garage were unlocked and untouched. After reading some complaints on here, I see there is an ongoing issue that may have been covered up by the dealership by cutting the wires. The location of the wires would have been extremely difficult to get to inside my garage. They also were cut and not chewed based on the pictures that were taken by the dealership for my insurance company.

My Santa Fe Hyundai 2012 accelerated unintentionally when I was turning into a parking spot. I was making a right turn into the parking spot when it lurched full throttle over two bushes and knocked down a black iron fence and I pressed on the brakes and I was on the side walk. I could have hit a pedestrian! it was very frightening.

18 Vehicle Speed Control problem

Failure Date: 09/02/2012

We experience a feeling of loss of power and almost stalls while trying to make left or right hand turns from a complete stop. It has happened since we purchased car in 2012 but so intermediately that we would just try and explain it away (we came up with OH - we are traveling in the mountains, got bad gas, weather hot, weather cold, maybe I imagined it) but when I almost got hit in the side took it in to dealer again. They have had it 4 times for the same trouble and until the last visit could not duplicate it - dealer in June 2014 kept car many days and then I received a call from service manager who asked if I braked left footed - well yes I do as my husband does. He said they could duplicate the problem only when they left footed braked and their solution was to not do that. I asked some more questions, basically why that would make a difference since we have always done it. He said since the Toyota problems the sensors in cars are more sensitive? I told him there are over 80 complaints with the odi for same problem in 2012 Santa Fe - he said OH that is a different problem - I read all of them - trouble sounds the same to me. We researched this car before buying - nothing in their advertisements, paperwork or on the net said left footed braking will cause your car to stall - we would not have purchased it however, I am not even positive that is the problem. I did also open a complaint with Hyundai - they denied a claim of a lemon car and said to just to stop braking left footed. The letter said they drove it 200 miles with no duplication of trouble which is not what the service manager told me - they were able to duplicate it. We now have a car I will not drive because it is dangerous and who would buy it since we would have to disclose this hesitation problem. Just rec. Letter from lawyer asking us to call him - have not yet.

19 Vehicle Speed Control problem

Failure Date: 07/25/2012

I pulled into a parking lot, in front of a bakery, and stopped to allow a car to leave a parking spot. I then proceeded to pull into the vacant parking spot and when I applied the brakes, the vehicle sounded like it was actually gunning into a higher gear, and as I was pushing harder down on the brake with my right foot the vehicle jumped the sidewalk in front of the bakery. I proceeded to apply both my feet to the brakes in hopes that the vehicle would stop, and it did. Thankfully no one was injured and the vehicle stopped before entering the bakery window. I called the dealership and arranged for them to tow it to their mechanics department.

While changing lanes, there was a sudden lack of response while I was pressing on the accelerator.

22 Vehicle Speed Control problem

Failure Date: 12/27/2011

While driving on an overpass and turning to the left, I had just applied the brakes and was applying the gas as I had to get onto the interstate. I noticed the car decelerated, I had no braking power and it was very difficult to steer the car so I coasted to the side of the road. I almost got rear ended by several cars behind me. All the lights were on the car but it seemed dead. I turned the key off and put the car in park. While talking to my husband, I turned the car on and it started and off I drove off with no further problems. What's worse is that day I had my two little girls and my mother in the car. I had to continue to driving since we were on our way to an important doctors appointment. I can't imagine if I were on the interstate at 70 miles an hour. When I called to make an appointment with Hyundai service they acted like it has never happened before.

My car does not ever stop when I try to stop. I can be stopped on an incline and the car will roll out in the main road and will not go in oncoming traffic.

I have had my car in the dealer several times and they say they cant find the problem with the car. My car has 28,000 miles on it now, this problem has been occurring since the car was new.
