The vehicle while foot on brake or while in park accelerates on its own! I almost got into an accident because my foot was all the way on the brake for car to stop but engine was still inching forward while in stopped position! when it is in park it tries to accelerate but ends up stalling out and then im unable to start back up for about 10 minutes also when going a steady city wide speed my car chooses to accelerate without making it do so this is scary I have 2 small children and this is dangerous I have carried it to 2 different machanic shops one being Firestone best of the best and have had diognostic tests conducted and they are unable to find the cause of my issue! it happens at various times I have read many of the same issues happening online with the tuscons and Santa Fe this issue needs to be investigated! I almost hit someone in the rear end with my foot completely on the brake! and it was as if I was fighting with my vehicle to stop

While driving one day, I felt my car shift as if the wheel had slipped, this occurred many times after making a turn. I recently had work done to the front (strut, tie rod, knuckle, ball joint) and am also in need of a wheel alignment. I wondered if this was why, so I called the mechanic back, but he told me that it was my tires. However there is still a fair amount of tread on my tires, so I am not sure if thats really true. Next thing I know, my car accelerated out of nowhere and was almost like driving itself at 20mph (the speed it was stuck on even after slowing down). Also while on the high way it did the same thing-- accelerated on its own and jerked to the right. I had to pretty much hurry and catch the wheel before slamming into another car while on a turn and going about 55mph. At random times it will accelerate and pretty much drive itself while I am driving. I typically have to apply plenty of pressure to the brakes to keep it from rolling while I am stopped. Also I am having an issue with overheating. If I idle too long the car will overheat, even though the tank is full. Even with adding more in, the tank stays where it is, it doesn't overflow. It's almost as if the car is just drinking it but it's not filtering through the hose if that makes sense. Lastly, the car did not want to turn on this evening, after about the 5th time I held it longer than usual and it finally puttered to life reluctantly. I don't feel very safe in this truck anymore.

When slowing or idling the car will stall and come to a stop, unable to accelerate again. As the car stalls it becomes very difficult to steer and all the dashboard lights come on (check engine light, oil light, emergency break light, etc). This usually happens when I am slowing down to make a turn and has happened once on the highway. Very scary and dangerous to come to a sudden stop while trying to take an exit on the highway.

When I went to put on the brake to park there was a sudden acceleration and the vehicle hit the building in front of the parking space.

I was preparing to pull into a parking space in a parking garage when the car suddenly went into rapid acceleration. It smashed into the cement wall of the parking space and surged for a few seconds before I could get the key turned off. The sudden rapid acceleration occurred again while in idle at a stop light and my foot was not on the throttle.this occurred several months later when the mileage registered approximately 36750. This time the surging lasted several seconds after applying the brakes and putting it into park to stop the forward motion before hitting the car in front of me.

I was driving in traffic on a two lane road. I heard a load bang and my car began to speed up. I tried braking but I could not slow or stop the car. With traffic in front of me I pulled into the left lane not seeing any oncoming traffic. Then a car was coming in that lane so I threw the car into park and pulled up on emergency brake. Since it was raining, the rear end of the car came around and I got hit on the passenger side rear door. The car finally stopped against a fence with the engine still racing.

While turning into my carport, my engine stalled. Right before I turned, I took my foot off the accelerator and the car hesitated and lurched forward. This could be a potentially dangerous problem if my car stalls on the road and some other driver rear ends me.

I have a 2006 Hyundai Tucson and twice now I have experienced sudden acceleration. The first time I was backing out of a parking space and the car surged backwards and I had to apply the brakes hard. The second time I had just pulled out of my driveway and touched the gas pedal and the car surged forward for a few feet before slowing down.

My 2006 Hyundai Tucson has stalled out repeatedly during deceleration. It has died repeatedly while turning into a parking lot. It has also died while slowing down for a stop sign. It has jerked and felt like it was down-shifting (hard)while driving on the highway. Today, 10/1/10, it died while driving through an intersection. I have taken the car to the dealer three times and they have been "unable to recreate the problem" so nothing has been done to fix it.
