So the radio stays on and illuminated and they push button start turns red also on the dash the immobilizer indicator pops up and says shift into park when technically the car is already in park. When going to get out of the car with the key makes the alarm noise. The key for will not even work. But while all of this is still happening I'm able to start the car with no problem .

When driving on the interstate my car continues to jerk like I hit something and the immobilizer indicator light flashes on and off. I have changed the battery in the key fob but this still happens at least once a day. The car jerks very hard like you hit a wall.

I've had consistent problems with my engine. Problems range from the check engine light coming on several times over the past 2 years, twice since 2017 started, 2). I've complained to the dealer about the abnormal amount of engine oil the car uses in less than 20,00 miles. 3). Engine will not start, even when there is no alternator or battery problem. 4). Car doors lock with key fob inside. 5) shaky steering wheel, that I've complained about since I owned the car. 4) seats are suppose to be leather, "leather" is cracking in the front around the base of the seat. (dealers says it's normal wear and tear. I've had leather seats before and none of them cracked).

An existing recall (the federal safety agency campaign number: 13v113000) indicates that for 2011 hyundai sonata the stop lamp switch may not function correctly. The recall notice states that: "during the affected models' production periods, some vehicles were equipped with stop lamp switch assemblies that may experience intermittent switch point contact. Potentially result in intermittent operation of the push-button start feature,(wich is happening) intermittent ability to remove the vehicle's shifter from the park position( also happening), or intermittent operation of the stop lamps.(happening also)" all of these symptoms have been observed in my vehicle, yet the brake light swtich was replaced on a routine service for a recall in 2014. I was not experiencing any trouble at that time. Now at 65000 miles and less then one year later my brakes wont turn off when my car is off resulting in my battery to die. Hyundai has had to come jump my car three times. When I brought it in they said they already replaced it and are no longer liable for it. Now my car is stopping and not allowing me to accelerate intermittenly during driving the vehicle. I also smell burning rubber coming from the inside brake area near the switch. Secondly, my steering coulum and alignment were off. I brought the car in to hyundai in 2014 because of the steering being very looose and making a knocking noise when you moved it back and forth. They said it was the coupling wich they reaplaced and it did not resolve the malfunction. They then replaced the steering rack and perfomed an alignment and tire rotation with new tires. The noise went away but the alignment is still terribly off. Now when I make right turns it makes a loud clicking noise again and shakes at 65mph or over. My warrenty ended at 60,000 miles and now nothing is covered. I paid for an extended warrenty at purchuse of which they have no record of.
