When vehicle was moving it felt like went into a coast but RPM did not increase speed slowed.. gas peddle was pushed in nothing happened when peddle was released and then pushed all functions resumed
While driving at night, the headlights will turn off when using the turn signal or turning on the high beams, I have to wiggle the headlight switch to get them to come back on. I have sent Hyundai an email concerning this problem as it is a very serious safety issue and the problem is getting worse, but of course there has been no response from Hyundai. With all of the complaints on the internet about this problem. Hyundai needs to issue a recall.
Car losses power in the highway under 55 miles per hour. When starting from stop or yield it does not take acceleration and almost dies. Almost got in acccident several times as the car doesnt want take gas. More like a suden stop in a trafic.. airbag light is on for more than a year. Brake lights dont work and is not the bulbs. This is becoming almost everyday problem and dealer dont have solution to the problem but I was told it is a known problem for this model. Pls do something about it.
Key gets hung up stuck in ignition will not shut off at times must work gear shift shoving it back and forth to release key and pull out while doing this car can also roll out of its parking space and cause problems.... the vehicle is and was stationary but this has happened on city streets on a hill as well very dangerous. I have read up and seen this numerous times from other people as well so I know it is not just this car
Did some research and from what I've been reading my 2011 Hyundai Sonata gls 2.4L is affected by the "starter lever" recall. I went to turn my car on the other day and it wouldn't turn on and just made a hissing sound as I turned the key. Went to the auto parts store to have my starter tested and it failed on the diagnostic right away. I need my started fixed and replaced so my car doesn't die on the freeway! had to turn my key and try start the car at least 10 times before it would crank over.

The contact owns a 2011 Hyundai Sonata. While driving approximately 50 mph, the engine stalled and the brakes failed without warning. The vehicle was restarted and the failure recurred. The vehicle was driven to the mechanic. The failure was diagnosed as an engine issue. The VIN was included in an unknown recall. The failure mileage was 112,000.
The power steering on my 2011 Hyundai Sonata stopped working approx. 1 week ago without any advance warning. The car is of course very difficult to steer without the assistance of power steering. If my Sonata is not one of the cars covered by the recall notice very recently announced, then the recall needs to be expanded to include my vehicle. The car was stationary and I went to start the car, and the eps light was lit and I had no power steering.
The light for both the driver and passenger seatbelt not functioning properly will not turn off. The passenger seatbelt light stays at seatbelt off and the driver's will not turn off after the vehicle has started. Both stay on the entire time the vehicle is on.
While driving 45mph I experience my steering wheel shaking and it leaves the vehicle hard to control and it pulls to the right. I then started to experience my car not starting after sitting for not even 5 minutes and this has been occurring for 2 days. I took my car to the local dealership and was advised that I needed to replace the starter lever and steering coupler. Both of these are common defects of this model and has been recalled in the past. I called Hyundai today and was told that I am now responsible for the cost of the repairs regardless of what happened in the past. The repairs are going to cost me a little over $600 when the parts are plastic and wouldn't cost more than $20. A complaint has been filed with the BBB as well...this is a major safety issue on this vehicle and the manufacture needs to do a better job at building these parts.
To start with the airbag light on the drivers side will not go off even though the vehicle has never been in an accident. Additionally none of the steering wheel controls will work at all. I have looked online and these seem to be a rampant problem with the 2011 model.
When I place my car in park the car is, telling me to shift to park but I'm already in park. My car will turn off but my navigation screen stays on. Also the engine push to start/stop light won't turn off. In addition I am unable to use my favorite to lock the doors because it thinks my keys are still in the vehicle so I have to manually lock it. The car seems to stall occasionally and I have to gas it to pick up speeds and I've only had the car for two months.
ECM computer failed. Nothing will work. Not only undrivable, it is unstartable! had to be towed from our driveway. (many systems on this car have failed previously!!) cannot get local dealer to repair it. No one seems to know what to do. Hyundais are a joke!!
Hand brake light doesn't stay on. If the hand brake is applied the dashboard doesn't indicate that it's on. The car still drives and driver unaware that the hand brake is on applies brake causing severe sharing and loosing control of car. The car was driven on street for 8 miles with hand brake on.
The contact owns a 2011 Hyundai Sonata. The contact stated that the vehicle failed to start without warning. The contact stated that the vehicle was able to start after an hour of attempting. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 87,000.
When attempting to start the car yesterday normally, the car did not start. After reading the owners manual I discovered how to insert the smart key into a slot within the center arm rest compartment and the car starts normally. However the car cannot be locked or unlocked with the smart key anymore. The car was in the garage on the day of failure. Also when moving in reverse, and turning the steering wheel, there are clumping sounds from underneath the vehicle and that's getting louder. Unfortunately we owner's do not get any type of resolutions on these issues. Hyundai needs to step up and rectify these concerns. Ooh they got their money already....
Car will not start when I hit the start button. Sometimes it will and sometimes it takes 4 or 5 times to start. Car makes an electrical rattle like noise but doesn't turn over. Also, when I try to shut the car off, my display will tell me to shift to park and the radio will stay on. I've had the car in for the shift lever cable recall but I believe there is more to this. The car is doing the same thing before and after the recall fix. I commute 200 miles to work so the miles I post will be high.
Cant get light to work, have replace bulbs a few times, and have take it to an advance auto place where they have told me it's a problem with the electric work and engine not the bulb. The bulbs were fine and not burnt out. Have been having issues since last October 1st was only one head light now as of this weekend its both.
