1.) Throttle Control failure, and is available for inspection 2.) My and the public saftey was put in risk, as I lost control of the vehicle an almost had an accident, and could have hit another vehicle or person or building. 3.) The problem has not occured again other than the multiple times on 10/10/2023. The problem has not been confirmed by a dealer or independent service center. I had O'Reilly Auto Parts check for failure codes on 10/10/2023 and found none. 4.) The vehicle or component has not been inspected by the manufacturer, police, insurance representatives or others. 5.) There were no warning lamps, messages or other symptoms of the problem prior to the failure. The next morning when I started the vehicle the "Cruise" lamp was on. While idling in heavy traffic, vehicle throttle began over revving with my foot on the brake, I was not using Cruise Control, I had not used Cruise Control for over a week. I did not see the Cruise indicator on. I had to push hard on the Brake to keep the vehicle from lurching forward, I almost could not keep the vehicle from ramming the car in front of me. I pulled off of SR 32 in Eastgate, OH into a parking lot and it did it again, I put the vehicle in park and turned off the ignition. After a minute I started the vehicle again and it did it again, I turned off the ignition and waited longer. I started the vehicle again and within an hour, vehicle did it again in Covington, KY, I had to pull into a Motel parking lot and stomp on the Brake and throw the vehicle into Park with Throttle Running away. I turned the Ignition off and waited. Vehicle then acted normally.

(Service brakes, hydraulic, exterior lighting, Recall started in 4-1-2013, Recall #13V113000. Car was brought to authorized dealer on the same occasion as mentioned below and told the vehicle did not need that repair performed.) (Air bags : Frontal Sensor/Control module, Recall started 7-24-2012, Recall #12V354000.Car was nbrought to authorized retailer and told Hyundai no longer makes the part in order to resolve this issue.) There are 5-6 different lights, all of which are mentioned for the recalls as stated above and seems to be a solvable issue. I just don't want to learn one day that my husbands cruise control did not disengage and he collided head on full speed. Hyundai needs to to start producing the part in order to fix the cars or recall them all together for fear of multiple lawsuits. Photo evidence of dash lights and screenshots of recalls can be provided upon request.

My car had the brake light switch repaired in 2013 before I owned the vehicle under recall 13v113000. Now the brake light switch has failed again. I first noticed the issue when I went to start my car and could not put the car in reverse. This happened seemingly out of nowhere after the car had been parked and off for about 10 minutes. My brake lights, electronic stability control, and cruise control do not work and I cannot shift the transmission. When I called hyundai I was told that the part was replaced in 2013 so there is no longer a recall option, even though the part is failing again.

While driving on the interstate at approximately 70 MPH, using cruise control, the car suddenly lost power. I stepped on the gas and it would not accelerate. I coasted to a stop and pulled onto the shoulder. The engine was running, transmission was in gear, but the car would not move. I turned off the ignition and let it sit for a few minutes. I restarted it, had power, everything seemed normal, except the engine light remained lit. I drove approximately 10 miles to my destination. The car sat for six hours and I was then able to drive the 65 miles home without incident. Repair results: my hyundai dealer indicated the problem was caused by a 'throttle position sensor'. They replaced the electronic component and reset the error codes in the vehicle's computer.

While getting onto the highway from the on ramp the car began to accelerate on its own. The gas pedal began to depress itself without me doing it. The cruise control was not engaged and the floor matt was not the cause. Braking was difficult and the engine continued to rev. I pulled off the highway and stopped the engine. After telling my family about the incident my daughter told me that it had occurred twice before in the same manner about 2 months ago.

Purchased 2009 hyundai santa fe from herrnsteins hyundai of chillicothe, oh. In january 2010. On two separate occasions; once in march, and once in june on 315 columbus, ohio. The first time it over accelerated I was attempting to pass another vehicle. I accelerated to pass and then was attempting to slow back down when I heard the engine rev and felt the vehicle speed up. I do not and did not use the cruise control. The breaks only slowed the vehicle I could not get it stopped. I did manage to shift into neutral and as the engine continued to rev, I turned the vehicle off. Upon restarting it was ok. The second time I was accelerating to merge, upon completion of the merge I attempted to let off the accelerator and slow down. Again the engine revved, and I felt the vehicle speeding up. I applied breaks forcefully like before the vehicle slowed a bit but sped back up I continued to break using both feet and the vehicle slowed and was then ok. We reported this to the dealership each time it occurred. Their response was that it did not show a code. After the second event herrnsteins has shown concern and realizes their is a problem. However the hyuandi corp. Has taken the stance with us that they do not have a problem with sua in their vehicles and that ours is safe to drive. I suppose because I did not get killed or kill someone else that I can not prove it happened.
