1) historical details / event: When I bought the car (August, 2012) I noticed the occasional sticking of the throttle and when pressing the break the car would seem to want to accelerate - this would happen once every three months: The dealer said they couldn't find anything. 2) recent event: On 07/07 while driving at 45mph the car immediately started slowing down to less then 10mph and the check-engine-light came on. After pulling over and sitting for a while the car would go up to 30mph - 40mph: Over that and it would occur again. Per the dealer - drove it to them. On the way - this slow down occurred multiple times between 30-40mph, once while slowing / breaking - the car immediately accelerated (RPM over 2500) and I almost had a major accident. Dealer diagnosed it as a known issue related to tsb: 13 fl 002 (throttle body bore carbon fouling / P2106/P2110 limphome mode / P0638 throttle actuator control range and that the break issue was due to excessive break booster air causing the throttle assembly to lock open. Dealer claimed issue was known but not seen often and never repeated. Had car all day to fix (finished: 07/08). Asked dealer about other tsbs in the database and was told none of them applied or were applicable. 3) recent event: On 07/08 after leaving the dealer, got 9 miles of driving when it occurred again after making a 25mph right turn and accelerating to 40mph [almost was read-ended by a truck]. dealer now closed for the evening. Will be contacting dealer first thing on 07/09 and demanding fix and/or replacement - as this is now multiple times with the dealer denying the severity of this.

2012 Hyundai Santa Fe had complete power loss on interstate while moving at 65mph in the left most lane. Engine shuttered, check engine light came on and engine power went to idle RPM. There was no throttle responce and steering became heavy. Managed to cross two lanes and get the vehicle to the shoulder. Shut vehicle off and restarted it. Check engine light stayed on and engine appeared to function normally. Accelerated from shoulder into traffic. Drove for 1/4 mile and incident again repeated itself as described above. Fearing for my safety, I parked the vehicle and had it towed to dealer whom I purchased vehicle from. I called (on 5-2-13) the dealer and told them what was happening. The next morning (5-3-12) I called them at 9am to find status of repair. They stated it was already repaired. They stated it is related to the trottle position sensor. They stated they were well aware of the problem. They stated they were having many of the same issues with this type of vehilce. They stated there was a tsb on the problem. Does someone have to be injured or killed before a manufacture has the obligation to correct a known problem that repeats itself" look at all the other reports and complaints! I have a wife and 2 children that ride in this vehicle. What now"

I was stopped in a left turn lane and I believe I was the 8th or 9th vehicle in line. I had my foot on the brake pedal and the pedal went to the floor! I turned my steering wheel to the left as far as I could, but I tapped the bumper of the vehicle in front of me. There were no injuries and very minor damage to the rear bumper of the vehicle in front of me, and very minor damage to my front bumper. No other vehicles were involved. I called the Hyundai dealership and told them that my brakes had failed and had caused an accident. I was told that it was probably not the brakes, but the master brake cylinder. I had the vehicle towed to the dealership (carl gregory Hyundai, at northlake, columbus, ga) this morning I called to check on the status of the vehicle and was told that they had driven the vehicle for 200 miles and could not reproduce the problem. I had already told them that I was stopped in a turn lane when the brakes failed!! I was told that the Hyundai representative told them to replace the master cylinder.

I pulled into a parking lot, in front of a bakery, and stopped to allow a car to leave a parking spot. I then proceeded to pull into the vacant parking spot and when I applied the brakes, the vehicle sounded like it was actually gunning into a higher gear, and as I was pushing harder down on the brake with my right foot the vehicle jumped the sidewalk in front of the bakery. I proceeded to apply both my feet to the brakes in hopes that the vehicle would stop, and it did. Thankfully no one was injured and the vehicle stopped before entering the bakery window. I called the dealership and arranged for them to tow it to their mechanics department.
