The cruise control comes on by itself during normal driving. After the "cruise" light comes on the "set" light illuminates and the vehicle accelerates without warning. The brake will momentarily stop the acceleration, but the acceleration resumes once the brake pedal is released. It occurs above 25 MPH. It kept accelerating and would have continued if I hadn't hit the brakes. I happens regularly, and we have parked the vehicle.

What owners say
I own a 2006 hyundai sonata, at 100,000 (hwy miles) the front upper control arms became squeeky and detatched from the rubber bushings, making a horrible ride and clunking sound when I would put the car into gear. This problem makes the car bouncy and unstable. There is also a knocking or loud clicking sound in the engine at crusing speeds, when I barley push the gas pedal. It sounds like the air intake control valve. It goes away when I accelerate. The radio and cruise control electornics seem to work only when they want too!
On march 9th, 2015, I was driving home from work after picking up my infant daughter from daycare when several warning lights illuminated on the dashboard of my 2006 hyundai sonata; the airbag, ABS, and ESC off warning lights. In preparation for the upcoming left turn into my neighborhood, I tapped the brake pedal to disengage the cruise control and coast to the intersection. The cruise control did not disengage. I applied more pressure to the brake pedal to slow down, but upon releasing the brake the vehicle returned to the set cruise speed. I now applied as much pressure as I possibly could to the brake pedal and the cruise control set light did not disengage. The sonata downshifted and revved up to 4k RPM attempting to overpower my braking. At this point it was too late to avoid the intersection. I placed the car into neutral and swerved to avoid hitting an oncoming vehicle and median, at the turn. The sonata spun out and came to rest in the oncoming traffic lanes after overshooting the turn. I verified my daughter was uninjured then proceeded to drive the sonata, at idle, the remaining 1/8th of a mile to my house. After arriving at home, I visited hyundai's and the federal safety agency's vehicle recall information web pages and found no recalls regarding my sonata's VIN.
While turning corners the engine shuts down and unable to turn steering wheel. Restart car and it works again. Has happened numerous times. Airbag light has been on continuously. Brake lights replaced freq. Cruise control no longer works. Esc light comes on intermittently. Had to use shift lock release numerous times for 2 days at a time. I am unable to put the car into reverse or park and I have to use the shift lock release to move the gears. Heat and air conditioner stop working a few seconds at a time. Engine light comes on for a few days at a time. If I hit the brakes hard the ESC light will come on and do not go off for days. Cigarette lighters replaced and one still will not work. Head lights dim intermittently. I have brought back to dealership many times and have spent hundreds of dollars and time off work and problems return quickly.

Electronic stability control: automatic (ASC)
- What is wrong
- On certain passenger vehicles equipped with 3.3 liter engines and electronic stability control (ESC), the ESC may have been programmed to be oversensitive to the onset of oversteering while driving on banked curves, causing inadvertent application of the front outside brake when ESC activation may not be needed.
- Risk
- This may cause the vehicle to slow and may affect the path that the vehicle is traveling. Brake application caused by inadvertent ESC activation may result in a crash.
- Remedy
- Dealers will reprogram the ESC hydraulic electronic control unit. The recall began on july 29, 2005. Owners may contact hyundai at 1‑800‑633‑5151.
