Automatic Transmission problems of the 2009 Hyundai Santa Fe

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 March 11, 2011 I parked my 2009 Hyundai Santa Fe in my driveway. As I was geting out of the vehicle it started to move. It dragged me down my driveway and as I was trying to get back into the vehicle I banged my right knee on the the steering wheel and it turned and went down a hill and hit a tree with me still hanging half out of the vehicle. I broke my right tibia bone. I also have never had a ticket or an accident before in life. Very scary. Did anyone else have a problem like this??.

2009 Hyundai Santa Fe accelerated on its own & could not be stopped until I put it in neutral & shut off the engine. This happened twice in two days. The first time this happened on the turnpike, the car accelerated to over 100mph before I put it in neutral but the rpms continued to rise until I shut down the engine. Applying the brakes did not help because the car was accelerating at too high a rate of speed. After turning off the engine, the car was difficult to steer & it was difficult to apply the brakes because of the loss of power to those systems causing an addition hazard.

On April 24,2010 I was unloading my 2009 Hyundai Santa Fe in the driveway. When I got out of the SUV and took my foot off the brake the SUV rolled forward a few inches. I put my foot on the brake took it off and wiggled my body to see if it would hold. I exited the SUV and spent the next 10 min, unloading it. When we were finished I decided to leave SUV in driveway and opened the door to remove the key. I leaned in and grabbed the steering wheel and reached over to pull out the key. Suddenly the SUV started to roll down the driveway and dragged me with it. It threw me to the ground and rolled over my right foot and left knee area of my leg and kept on rolling into the middle of the street.
