The vehicle would randomly accelerated without warning. During the failure, the rpms would increase and the vehicle would lunge forward. The failure occurred on multiple occasions. The contact would have to apply extra force to the brake pedal to prevent the vehicle from accelerating around 70000 on car. It has a jerk when I am accelerating until I get to a faster speed. But it doesn't accelerate on its own.. I was string at a lightor whenever I go to stop it accelerates on its own. Sometimes while I'm driving it seems to pick up speed on its own as well

What happened: We were at a friend's house for dinner. We came to the car late at night and put the key into the ignition but the key would not turn. I tried to rock the steering wheel slightly while tried to turn the key without any success. Without engine power, no steering was available. Fortunately, my friend dropped us at our home. The car was towed to the Hyundai dealer at glassman Hyundai in southfield the next morning (July 28) with great difficulty since steering was locked. I saw a mechanic working on a similar car in the parking lot with similar issue and he said that he will be working on my car also. He also said that ignition key cylinder are wearing out and needs replacement. Counter person said the key cylinder needs to be replaced at the whopping cost of $650. Later she said $850 upfront. Later declined to service and I had to tow to another place and they replaced key cylinder for $380. This is dangerous safety issue since I could have been stranded on a freeway after a rest stop in the middle of night. I had never encountered this issue in my 45 years of driving. I did some internet research and found that many others are having the same issue on the same cars. The switch is faulty and seems like it is wearing out faster for some reason. I have only 73K miles on it and the car sits in the garage most of the time. The dealer says that it is not covered. I think Hyundai should take the responsibility to fix this issue for all 2007 Sonata vehicle. I think Hyundai should own this issue and replace the cylinder locks on all such vehicles at no cost to the owners.

While trying to park my 2007 Hyundai Sonata the automatic transmission shifter was stuck in drive and can only be moved into neutral. Leading up to this happening the ESC light kept coming on and eventually stayed permanently on. I later found out that my break light was also off. I am able to move the shifter by pressing down the bypass. As it is in order to take the car out of park I have to press down the bypass. I have to do the same when going from drive to reverse or from reverse to drive. Break light still not working and ESC light is on.

Car began "jerking" motion while doing 45 mph to 50 mph. Dealer says they are unable to locate problem as there is no code. Transmission fluid was changed and temporarily "fixed" the issue. Two different dealers have looked at the car and have both said without a code, they can't find anything. The tach does not fluctuate when the problem occurs. After 50 mph, the jerking motion stops. This is a 4 cyl, 2.4 liter engine.
