The contact owns a 2005 Hyundai Santa Fe. While driving less than 20 mph, the vehicle accelerated when the brake pedal was depressed. The failure occurred intermittently while slowing down and attempting to brake. The contact thought that he may have been depressing both the accelerator and brake pedals simultaneously, but this was not the case. The failure began to occur more frequently. While slowing down to come to a stop, the vehicle jolted forward and accelerated loudly. The failure mileage was 20,000 and current mileage was 31,000. Updated 12/11/08 the consumer stated when the transmission was in drive, his foot was off the gas pedal the vehicle moved slowly. Once he depressed the brake pedal to stop, the engine surged.

When accelerating from a stop, this vehicle hesitates and then lurches forward with extreme uncontrolled acceleration. On wet or slippery pavement this vehicle is completely unsafe. I have read NHTSA web site and can see complaint after complaint on this vehicle, yet no recalls issued by NHTSA. Not sure why we are wasting my time, but at least when I am killed in this vehicle my wife will be able to now include nhsta in the lawsuit as you, the governing body, have now been officially informed of a safety defect!

Gas pedal is to sensitive. Wheels spin when you excellerate at a slow speed. I have taken it to columbia hyundia 2 times and there isent anything they can do to fix it. I live in Ohio and we get lots of snow im afraid im going to loose control of the vehicle on the ice or have some rearend me. There is no way to take off from a stopped position and not have the wheels spin and the vehicle to fishtail. You have to let off the gas then excelerate again to get this to stop.

Sudden engine acceleration when parking. This is the second time this happened. My wife was parking the car and when she put her foot on the brake (note, she is a very experienced driver and was not accidentally pushing the accelerator, also nothing on the floor was touching it.) the engine started to accelerate to full throttle, she jammed on the brake and throw it into park at which point the engine raced full speed until she turned off the key. It was ok after restarting, this is the 2nd time within a month. Very dangerous condition.

I am the owner of a 2005 Santa Fe w/a 3.5L engine. I've recently taken my vehicle in to have some warranty items taken care of. I asked that my car also be fixed in regards to an acceleration concern. For example: 1. while departing from a stopped position, the car will violently jerk your head back. This occurs while barely touching the accelerator. 2. when the car is in motion I can feel it surging forward and back. I have had several people drive the car to make sure it wasn't me, and they all experienced the same results. When the service manager at a Hyundai dealership drove the car, he at first said he didn't feel anything. Then, after further complaint by me, he admitted that, "well, there was a little bit of surge, but that's just because it's the type of engine". I asked what could be done about it and he told me, "nothing, that's just the way it is. They've had several complaints and now they don't use that engine anymore." I said it felt like it was getting worse over time and he said, "it probably is, but there is still nothing they can do about it". Hyundai was apparently aware that there is a concern of safety with this engine since they no longer use the engine and are manufacturing their Santa Fe's with an improved, safer engine. I am at the point where I no longer feel as if I am driving a safe vehicle and I am getting tired of people asking me why my car jerks forward. (the car snaps your head back and I do not want to be held accountable if someone gets hurt.) there are numerous complaints to the NHTSA and I do not want to be killed or kill someone on the road because my car concerns were not addressed by the appropriate administration of Hyundai. If the NHTSA has yet to formally force Hyundai into fixing this issue, I am requesting that now is the time to do so. Hyundai's lack of interest in the safety of their customers and the general public is unacceptable.

: the contact stated the engine light illuminated, and the vehicle was taken to the dealership. The ECU was replaced, and the float in the gas tank was replaced twice, but the problem persisted.

- Las Vegas, NV, USA

The contact stated while stopped at a red light, the vehicle lurched forward without warning. The vehicle stopped after applying brake pressure, placing the vehicle in park, and turning off the ignition. The vehicle was towed to a dealer who was unable to duplicate the problem, but suggested that the contact should not use floor gear shift of the automatic transmission as though it were a manual transmission while driving. The manufacturer was alerted.

My wife and I are experiencing a problem that threatens our safety every time we drive the vehicle. The problem has to do with delayed acceleration when applying the gas pedal, which causes fear when entering traffic or making a turn as opposing traffic approaches. The delayed acceleration is then followed by a lunging acceleration which reduces the feeling of control over the vehicle. I took the car back to the dealer in elgin, il a few days after purchasing the vehicle, but they brushed it off as a common characteristic of Hyundai vehicles with the 3.5 liter engine. They claimed that after some time the vehicle would "?adjust?" to my driving habits and the symptoms would go away. Their cavalier attitude did not sit well with me. After driving the vehicle for a month, I made an appointment for service to have them check the vehicle over. The problems that I had described previously had not subsided at all. The service manager and I took a ride so that I could demonstrate the acceleration and other problems that I was experiencing with the vehicle. He acknowledged the symptoms as they occurred and told me they would do a very thorough check of the vehicle. To my chagrin, when I returned to the dealer service department to pick up the vehicle, the service manager told me that they could find nothing out of the ordinary with the vehicle. I was assured that the acceleration characteristics that I complained about were normal for this vehicle and that I would just have to get used to it. I have driven the vehicle for almost three additional months, but the acceleration is still erratic and makes me very uncomfortable when accelerating from a stop or even when accelerating on the expressway. This vehicle is compromising my safety, and I cannot accept the explanation that this is normal. This problem needs to be addressed before my wife or I get injured or killed due to the performance problems of this vehicle.

To whom it may concern: We are writing to you concerning a safety problem with our Hyundai Santa Fe SUV that we purchased in September 2005. We have returned to the dealership on several occasions as well as contacted the Hyundai corporate usa headquarters, but to no avail. The problem relates to the gas pedal and its acceleration. When the car is at a stop and you apply your foot to the gas pedal, it hesitates and then lurches forward. This in itself is dangerous enough, but if the roads are wet or snow covered, the car tends to slip and skid. By way of explanation, the dealer claims this delay in acceleration is due to the fly-by wire acceleration system. Interestingly enough, the dealership and the head quarters acknowledge the problem, but state that it is merely a function of the vehicle and there is nothing that can be done. We would like to see this problem corrected before a serious accident occurs and would appreciate any assistance that you could provide. Thanking you in advance for your concern and help. Sincerely, bruce and lynne blatt.

The throttle hangs up when going from a dead stop. This causes the car to lurch ahead so fast it spins the tires. This will cause you to rearend a car in traffic, or to pull out in traffic to late which could also cause an accident.

While the contact was pulling into a parking place the vehicle surged, causing the engine to rev above 6500 rpms. The vehicle accelerated and took off on its own. He reported having no problems with the vehicle prior to the above incident. He has not taken the vehicle to a dealer.

- Winston Salem, NC, USA

The contact complained about several problems. The first problem was the traction control, which allowed the front wheels to slip in the snow. The electronic accelerator cut in and out when the traction control was on. The dealer was contacted, and they suggested turning the traction control off. The contact tried the dealer's suggestion. And now, only one wheel will turn in the snow, the engine idled low, and the vehicle did not move forward. The second problem occurred on normal road conditions the vehicle lurched forward after a complete stop. The last problem was the check engine light which intermittently illuminated. The dealer replaced the dps valve sensor and reprogrammed the computer software. The contact had only driven the vehicle once since the repairs were completed, and did not notice any difference in the performance of the vehicle.

When put into reverse 2005 Santa Fe engine roared. The consumer had no control over the vehicle. With the vehicle still in reverse, the consumer crashed into a neighbors deck causing a considerable amount of damage to the vehicle and the deck. The consumer had a left foot accelerator installed on the vehicle and wondered if that was the cause of the sudden acceleration.

Accelerator pedal. Vehicle hesitates when taking off from a stop, then suddenly accelerates sometimes much to quickly causing some loss of control. Mechanic at Hyundai tried to reset computer but informed us that it is set to manufacturers standards problem has so far been un-fixable and the vehicle remains unsafe.

Complaint is about a 2005 Hyundai Santa Fe LX with 3.5L engine. There is a problem with the accelerator that there is a delay in response when the accelerator is pressed. This delay is over a second long, and causes the driver to keep pressing down on the accelerator. When the sensor finally reacts, there is more acceleration applied than is desired, causing the vehicle to start out faster than intended, or not starting out when the driver wanted to. This is dangerous as the driver does not know how much acceleration will be applied to the engine, or when the car will start moving, thus making it difficult when to apply gas, and not knowing how the car will react.

- Pen Argyl, PA, USA

The vehicle experienced delayed acceleration. Contacted the dealer and manufacturer. They said it was a characteristic of the vehicle. If at a complete stop and consumer pushed the gas pedal it took a few seconds before vehicle will accelerate.
