1/23/2016 8:02 am I received a call from my wife who was driving her 2012 Hyundai Sonata on the I-95 in South Florida on the way to work going approximately 70 mph, when she went to accelerate to overtake a car driving slower. All the lights on the dashboard went on and the car completely lost acceleration power and the speed dropped all the way down to 40 mph. When the speed reached 40 mph, she could not accelerate anymore and hence quickly pulled off to the side of the road (upon my request). Due to the heavy traffic, she was extremely lucky not to get into an accident. When I arrived to switch cars with her, the car started fine and accelerated appropriately. I took it straight to the Hyundai dealership who after running diagnostics came up the following: No codes stored in memory and no signs of what could have caused the car to act like this. They recommended a throttle body cleaning which is currently being completed (I am writing this from delray beach Hyundai). They stated the throttle body sticking may be the cause, but went on to admit they really had no idea as diagnostics gave them no information. After this incident, we are concerned that the car is no longer safe to drive and the fact the dealership has been unable to come up with any cause is even more of a concern.

The vehicle has a history of losing power completely. At this point I am unable to enter the car with the keyless entry, you have to do it manually. The car was parked on the street. Once you put the key in the ignition the horn/alarm goes off and doesn't stop. It also seems to be revving while it is in park. While driving I experience little power surges from the car where it accelerates with me trying to do anything. There was also another instance where the car would not start once the emergency brake was engaged. Once disengaged the car started with a little hesitation. I only had the car for 6 months and have had to bring it back to the dealer at least 6 times.

Early this year when I started my 2012 Sonata in the morning for work it started to stall. In March when I took it to the dealer for oil change I notified them of this issue. They said the battery needed replacing. It got better afterwards until two weeks ago. I thought maybe the keyless remote needs new battery and so switched to the spare remote that I had barely used. It did not help. But I noticed the stall happened in the morning when I leave for work, not in the afternoon when I go home. Maybe because I have to use the remote to unlock the car in the afternoon and make the car connect to the "key" rather than display " key not detected." This morning I could not get the car started after tried all my tricks for numerous times. I was stranded and had to use my vacation for work. Made an appointment last week with the dealer for this Tuesday. Wonder how I am going to haul the car to the dealer if I can not get it started.

I saw the recall notice in the paper. Call dealer, had appointment today. When arrived told that there was not a solution to the problem yet. This is bull I think Hyundai is trying to figure out a cheap way to fix the problem. What happens if I am kill or injured before they find their cheap solution. This is my only car and because of my husband recent death, I cannot afford to buy another vehicle. Please try to expedite Hyundai to fix.

The front-end will wobble at certain speeds, around 25 & 45 mph. It has been to the dealer 3 times now. First, they fixed the alignment. Next, they said they couldn't detect anything wrong. Thirdly, I drove with the service manager, and he immediately detected a problem. He had the front 2 tires replaced, with alleviated the problem for a time, but within a couple weeks, the wobble could be felt easily again, at the same speeds as before.

I was in my parking space and had to put the car in reverse to get out of the space. With my foot on the brake and the car in reverse, it took off at an incredible speed, did a semi-circle, and hit another car. I brought the car to my local Hyundai dealer who was unwilling to do anything about the event or check out the car. I plan on contacting Hyundai corporate to provide them with this information.

Vehicle check engine lit and all dash lights lit upon starting the car. It would not let me shift it into any other gear. Car was towed to dealer for several days with them consulting with Hyundai. They replaced some control module to repair it. -------------------------- two weeks later, the same problem occurred. Idiot lights were on after starting the car, but I could not shift it out of park. Dealership swears its a different issue and they are consulting Hyundai yet again. My car has been in the dealership for over a week now and they can't tell me when I'll get it back.
