I had made a left hand turn and went to accelerate and the vehicle kept accelerating and the engine revved up, I tried to push the brake to slow the vehicle down and it would not slow down or stop. The engine revved up and finally after a few moments the gas pedal came unstuck. The car slowed down and I pulled over. Later that day my son drove the vehicle and it happened twice to him when he went to accelerate he said it just kept accelerating and he said he kept hitting the brakes until the care went back to normal. I did take it to the dealership where they said nothing was wrong with my vehicle. I did do a google search and it seems that other owners of the 2009 Hyundai Santa Fe reported the same exact problem.

Entered horseshoe casino parking garage and turned into parking level. As I followed Ford Taurus, Hyundai engine changed from normal speed to a roaring acceleration in an instance. I couldn't brake it to a stop and it rammed the rear end of the Taurus. Damage to the sante fe was limited to front bumper damage while the back end of the Taurus was driven forward and torn up. My husband thought the cruise might have gone on; but, he decided the acceleration was too rapid for the cruise. He was in the passenger seat. We drove home without any further trouble.

Driving my wife's car around 40 mph and for no reason the car started accelerating to a high rate of speed and I had to lay on the brake but when I took my foot off the brake it again started accelerating at a high rate of speed. I put the car in neutral and the engine was racing very high I shut the car off and started it again and it was back to normal. I am concerned that this will happen again. Talked to Hyundai service and they could not give me an answer.

Was going about 70 mph around topeka Kansas when the vehicle lurched, then the ESC, engine and chassis lights flashed. Immediately afterwards the car lost all propulsion. Fortunately I was by an off-ramp, but could of gotten in an accident which such a sudden deceleration. Managed to get to an autozone store to check the fault. The fault came up as the throttle position sensor (tps). Managed to get it to the dealership in topeka. They fixed in within 10 minutes, but after completing my trip back to Colorado noticed the car is lurching again in lower speed, in-town traffic...very dangerous!!! will be contacting the dealership in Colorado on Monday morning!! had a similar problem two years ago, took it into the dealership and they said they couldn't find a problem with it. Guess they won't be satisfied until the warranty period ends and someone gets killed.

Driving on highway, ESC light & check engine light illuminated, car lost power. After approximately 2 minutes, car restarted and retained power for approximately one year. This year, the car has duplicated the same problem 4 times within a month, and when foot on brake in drive, the car surges so badly that at times I thought someone had bumped the rear of car. I took to dealer today and they replaced the throttle position sensor under warranty. This was very much a safety concern, would often happen this year when vehicle was slowing, so that making a left turn put me in a dangerous situation.the replacement of the throttle sensor seems to have remedied the problem.

I was on a return trip of 5 hours or so each way which I took at about 30,000 miles on the odometer, and noticed a very pronounced drop in power and acceleration capability quite suddenly. It was as if some wiring or hose had come loose under the hood. A few months later, when the problem had not changed at all in over 3000 miles of day-to-day driving, including a daily stint (to work) of maybe 12 miles each way on the freeway which entails accelerating up the on-ramp into the flow of traffic, I still could feel the difference in acceleration and response time while accelerating. When I took the Santa Fe in for a normal oil change, I reported to the dealer these symptoms, and asked to have it checked out. They changed the oil, and checked out the computer readouts for the vehicle, and said there were no problems detected by the computer at that time, but when this type of behavior on the vehicle occurred, it was most often due to the fuel filter being all clogged up, although that still might not be the problem. They quoted me a price of $270 to change the fuel filter, and after I asked if there was any coupon discount for this service ever thru their dealership, the service manager gave me a coupon book for a flat rate off depending upon how much was being paid for. (it amounted to maybe $25 off this service.) they did not have time that day to change it out, so I decided to check out both whether there had been any complaints, service reports, or recalls about this fuel filter, and that is what led me here to make this complaint about both the cost of this replacement and the poor prognosis of it solving the acceleration problem. I am going to check with a repair place I feel confident in about their cost to do this replacement. Hopefully, it will be much less.

Upon entering the highway at 55 mph my 2009 Hyundai Santa Fe took off and the gas paddle got stuck for 15 - 20 seconds even though it felt like a life time. I stumped on brake pedal and tried to pumped the brake pedal to no avail. The RPM on my car was registered at 6-7 and the engine was very loud. I got the car to stop by placing the transmission in the neutral position. I called the nearest dealer to my home to make an appointment and they were not able to duplicate the problem. So to them there was no problem with my vehicle. To me and my two daughters this experience is a nightmare and the car is unsafe to drive. Since 2002 I bought 5 Hyundai cars (2002 sonata, 2003 Santa Fe (daughter in law drives), 2004 Santa Fe (son drives), 2004 Santa Fe (daughter drives) and my car 2009 Santa Fe. As you can see from my multiple purchases I loved driving and owning Hyundai Santa Fe's. I am very upset because we could have died! I am even more upset that Hyundai will not stand behind their products and make excuses so they will not have to make repairs. The $$$ must be worth more than peoples lives. The Hyundai dealer in North East philadelphia even had the nerve to blame me because he said not replicate the incident and it was not in the cars computer. Shame on you Hyundai, shame on you dealers. This is the last Hyundai that I will ever own, I will no longer recommend any of your cars to anyone but I will share my story with them. You lost a customer and I will join any class action suit and I will call the tv stations to report this problem. I do not think that anyone should die before you fix the problem - what about you Hyundai? peoples lives or $$$$$. I am planning on replacing the throttle position sensor and getting rid for the car. I do not want another near death experience.

Incident 1: (10-20-2010) driver side head light was fogging up constantly. Dealer replaced the head light under warranty. Incident 2: (02-22-2011) upon fill-up of the gas tank, just before it was topped off, there was a series of clunking noises. After taking it to the dealership, the gas tank was replaced. Incident 3: (05-01-2011 approx.) upon removal of the cabin air filter cover, the little plastic parts that are squeezed to remove the cover broke, which wouldn't allow the cover to go back on. The dealer replaced the part and I have not yet replaced the filter yet. Incident 4: (11-12-2011) driving 60 mph down the highway, I heard a loud banging noise coming from the engine compartment. As I was pulling over to check out the situation, the car lost power steering and air conditioning! my serpentine belt broke! after it was towed, the dealer replaced it, along with belt tensioner and idler pulley! incident 5: (07-30-2012) I was coming up to a stop light and upon deceleration, the check engine light and ESC off light came on. After coming to a complete stop, the RPM gage showed 1100 RPM and it felt like the vehicle wanted to move as if I was pressing the accelerator. When I did try to accelerate, there was no power to accelerate ( the engine was still running, etc, but when I pressed the accelerator, I could only move a few miles per hour.) I pulled over and shut the vehicle off for a few minutes. I started it back up and the check engine light remained on, and I gained acceleration power. I took the vehicle to the dealership. They determined I had a faulty throttle position sensor as well as brake light switch and both were replaced by the dealer. [current mileage on vehicle after all incidents: 48,897]

Recently while driving the car seems to hesitate then has a minor acceleration. It seems as if its about to stall but catches and accelerates or increases to original speed. This is concerning especially when it occurs during rush hour traffic. In addition, I had to replace the battery at 24, 348 miles as the car died on me twice while traveling. I purchased a battery from O'rielly auto parts as it was closer to my home. The dealer would only state that battery failure has occurred with less than 30,000 miles on the sante fe however since I didn't bring my car to them the battery is not covered under warranty. It is unbelievable that battery life is this short.

On Monday, August 22, as I was driving down pewaukee road, I decided to get in the left lane to pass a semi truck. Suddenly I hear the car engine revving and the car's speed was accelerating. As there was a car directly in front of me and the semi truck to the right, I was pressing on the brake as hard as I possibly could. The car was hard to control and for a brief time I was in the on-coming traffic lane. All I could think of is get on a side road. The car would not react to the brakes. I turned onto a side road, aimed my car at a road sign and steel bollards on the side of the road so they could at least stop the car, threw the car in park and turned the key off (I am not sure in which order I did the last 2 steps). Fortunately the car coasted to a stop. The engine was making a winding noise. Hyundai roadside service picked up the car. Their service manager indicates they can not replicate the problem. It was suggested I had the floor matt bunched up under the gas and brake pedals. Give me a break! I'm not a complainer. This is the first time I have ever lodged a consumer complaint. But I was scared to death at the time and I am very hesitant about getting back in that car tonight (my husband is picking it up from arrow Hyundai). I am not concerned about hurting myself -- I don't think I could ever get over it if I hurt someone else because of this car. So Hyundai can't replicate the problem. Did anyone think they would be able to" the question is what is Hyundai doing about a problem that seems to be very documented on the internet. What is Hyundai going to do when a sudden acceleration problem kills someone" Hyundai did nothing for me. They initially seem very perplexed about such a problem. However, today when my husband arrived with a hand full of printed blogs all they wanted to say was they couldn't replicate the problem but would document the problem. I don't trust that they will so I am documenting the problem myself.

I get acceleration problem in my Hyundai Santa Fe 2009., whenever my car gets slow it see car it going by it self even thou my foot in my the break. It also gives my feeling that car is stops and go something like car is jerking off. I even see lot of other people having the same problem. In March 201, my wife got in to the accident because of the acceleration problem. But, we did not realize that at that time. And, my wife told me that was the problem but we did not believe it at that time. Now, we are facing more problems. Dealers are not doing anything. They just told me that they don't see the problems. Can you guys really do something about this, before somebody gets killed or get in to the accidents. Hope you consider our genuine complain about acceleration problem complain for Hyundai Santa Fe 2009.
