What owners wrote

On 10/08/2009 my 209 hyundai sonata went into an unintended acceleration. As soon as I put the car into drive it began to accelerate. The brakes did not work and I was able to shift into neutral. I was on a narrow dirt road with little limited options as to where to steer the vehicle. I missed a boulder, garage, and tree before hitting the side of a house. The ambulance was called and I was transported to the local emergency room. I had a concussion, fractured knee along with a number of bruises and abrasions.

October 2016 FireInjury

Several driver side door electronics malfunctions. Lock button does not respond when trying to lock doors. Gas cap opener does not work. I have to manually open my gas cap through the trunk. Window auto close button not responsive most of the time.
