When I stepped on the gas from a stop at a red light the engine started racing and the throttle stuck.the engine wouldn't stop racing so I had to turn the key off to get it to stop. Pretty scary. A secondary issue is that the rear passenger seat will not flip up. It's locked in place.

Driving on the skyway heading into downtown Chicago on a Sunday morning. Speed was approx. 70mph. I got into the left lane to pass, and as soon as I did, I noticed that the left lane was ending about 1/4 mile ahead. I gave the accelerator a little extra, and the vehicle took off. The speed climbed to 75,80 then 85mph. The accelerator was not stuck, it was not a floor mat issue, it was a mechanical failure. I was standing on the breaks, with both feet, and the breaks were not functional at all. Fortunately traffic was light, and on the highway, there was room to accelerate to this speed without crashing the vehicle. Fearing what could be ahead, I eventually put the vehicle into neutral, which red-lined the RPM's, but did not slow the vehicle. I put it back into drive, hoping to restart or reset the accelerator/brake system, but it did nothing, so I turned off the engine, put it into neutral and eventually coasted to a stop on the off ramp. The brakes were still not working, and I lost power steering, but coasted to a stop. I had my wife and 3 children in the vehicle with me, and we are lucky to have survived the incident. Hyndai corporation has been completely unprofessional in this matter. By putting the vehicle in neutral to control the speed, the engine seized (estimate 6K repair) Hyundai would not pay for these repairs. Their Consumer Affairs division in Hyundai, didn't return my call within 3 days as they had indicated. I had to call them back and file a safety report, and eventually when they did respond, after multiple calls, I sent them an estimate, and they told me they would pay for the diagnostics, but no repairs.the engine has to run on its own power for them to "accurately assess" what happened.Hyundai is not interested in finding a fix to this failure.as far as Hyundai is concerned, the incident never happened.

While driving up an incline the vehicle began to make a grinding noise. Shortly thereafter the car began shaking, with the check engine and ESC lights both coming on, then a sudden stoppage of acceleration, and then engine shut down while the vehicle was still in motion. This caused the immediate loss of steering and the brakes to go soft. The vehicle sat for 10 minutes before re-starting; however, after driving approximately 100 feet, the car once again made the grinding noise, engine and ESC light illumination, shaking, and then shut down. This is the third time since purchasing this vehicle in March of 2008, that the engine has stopped working while driving. The dealership has replaced a throttle sensor twice, the last time being October 18, 2009, and it is currently in the shop again for the same problem. This is just one of several ongoing problems and concerns with this vehicle. Most notably outside of the sudden loss of power and engine shut off described, the brakes have been checked on several occasions for noises, violent shaking, and loss of function to which the dealership states that they are not worn or warped or this is normal for this vehicle. The tires have no grip and spin on both dry and went road conditions making sudden acceleration impossible and dangerous.the vehicle has also been checked for the lack of gas mileage approximately 13 mpg city and 16 mpg highway, well less then the 19/21 on the sticker.
