general problems of the 2011 Hyundai Sonata - part 2

After a complete stop, the vehicle will delay its acceleration, as if it was going to turn off, the after 3-4 seconds it accelerates, it happens several time a day while driving.

Defective brake switch stuck in on position caused the car slow down of its own accord in traffic. Car drove as if you had foot on brake and accelerator simultaneously. Brake lights stayed on after taking foot off brake pedal.

All of a sudden my car is having an a problem with accelerating. I was driving 40-45mph and the car decilarrated down to 30mph then to 20mph I stepped on the gas pedal all the way down and the car slowed to almost a stop, and then with my foot still fully down on the gas pedal the rpm shot to the number 4 and the car took off from underneath me if I hadn't gotten control I would have gotten into an accident thank god no one was in front of me. Mind you I had just left hyndai mechanics for the 2nd time this week with the reported problem and they still say they can't find nothing wrong. It happened randomly, but in the past week in a half more often then I'd like to count. It's a very dangerous situation especially when you have a child in the car and it's fusterating when Hyundai tells you if it continues to happen bring it back, for what for them to tell me the same thing they told me twice before , the first I was turning at a light the second on a highway the 3rd down a rural one way road and another while making a u turn.

Cruse controls does not engage and/or does not disengage.

The contact owns a 2011 Hyundai Sonata. While driving 25 mph and making a left turn, the rpms increased independently and the vehicle lunged forward without warning. In addition, once the vehicle was placed in park, the rpms continued to increase and then decreased. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 60,000.

During my last scheduled vehicle maintenance in April 2016, I explicitly communicated my concerns to the Hyundai dealer about my engine and the fact that the oil light kept coming on when I tried to accelerate and would go off as soon as I took my feet off the accelerator. I just found out through local news and information from online blogs that this was a sign of engine manufacturing problems originating from Hyundai's alabama engine manufacturing plant. The dealer did not inform me that the engine in my vehicle was being recalled. Instead, I was told via the maintenance report that oil level was low and there were no visible leaks. I have receipts to prove that I adhered to all recommended owner maintenance services and have been diligent enough to service my vehicle according to the service schedule prescribed during vehicle purchase. I have strong reasons to believe Hyundai has not been honest with its customer. This being because, rather than elaborate on the cause and solution to the problem (I. E. Hyundai Sonata 2011-2012 engine recall), information was deliberately withheld from me by Hyundai. I never received a recall notice from the dealer despite purchasing the vehicle from an authorized Hyundai pre-owned vehicle dealer. I'm even more frustrated because this recall was announced in September 2015, 4 months after I purchased my vehicle under warranty and paid extra to have extended warranty coverage added on my vehicle. It¿s now 7 months after the recall announcement and I still have not received notice of the recall from Hyundai. As of today, 3 weeks after my vehicle stalled on the on-401 highway whilst driving at approx. 100km/hr. , I have not heard back from Hyundai. I had to coast my vehicle to the outside shoulder of the busiest highway in north America at 9:00pm. 3 weeks on, I have no vehicle, no repair timeline and no response from Hyundai.

The contact owned a 2011 Hyundai Sonata. While pulling into a parking space at approximately 5 mph, the vehicle accelerated and crashed into a building. The failure occurred without warning. The air bags deployed. The police was called to the scene and a police report was filed. The contact sustained injuries that required medical attention. The vehicle was towed totalled by the insurance company. The manufacturer was not made aware of the failure. The failure mileage was 85,000.

The contact owns a 2011 Hyundai Sonata. The contact stated that while stationary, the engine made a loud noise as if the vehicle were to independently accelerate. The contact had the engine replaced under a manufacturers recall but the failure recurred. In addition, the steering wheel did not support the movement of the vehicle while driving on numerous occasions. The manufacturer was made aware of the failure. The failure mileage was approximately 74,000. The VIN was not available.

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.

October 3rd 2015, I was driving on highway 78 west. I was in the vehicle with my 3 year old daughter. I was driving in a 2 way lane that was under construction. All off a sudden without any warning my vehicle started to decelerate on the highway. I immediately had no control and my speed was decreasing fast. I was in the left lane and in matter of 4-7 minutes my car engine was shutting down on the highway. I was almost hit by multiple trucks who continued to fly by my vehicle on the highway as I tried to find somewhere in enough time to bear off. Putting me and my 3 year old daughter in immediate danger. Needless to say I was terrified. I was finally able to pull off into the right lane and pull my vehicle into the shoulder of the highway. Since I was in an area that was under construction on this highway the shoulder space was very limited. I could feel the trucks pass my car and I was scared for my life and my daughter¿s life. I had an immediate panic attack and thought my daughter and myself was going to die. This has caused a great deal of hardship on myself and my daughter. We have been without our vehicle since this incident. Hyundai in lebanon, PA has had my vehicle since 10/3/15 and continue to give me the run around. They say they ordered a new engine , but it has not shipped to the dealer yet. This incident has created a tremendous hardship for me and my family . I continue to be at a disadvantage as I am driving a rented vehicle . Meanwhile I continue to pay for a car I have not driven for over 3 months. Your immediate assistance would be appreciated. This issue I am having with my vehicle is due to a recall campaign 132. This recall was due to the engine malfunction that Hyundai is aware of. My vehicle stalled while in motion on the highway , putting my life and my 3 year old daughter's life at risk.

On March 11, 2014 approximently at 3:30 pm I went to my car in underground garage. I entered car put seat belt on put car in reverse then when putting car in drive steering wouldn't move and without acceleration the car took off- sped. My foot was on brake when car took off. At that time I tried to brake and had no steering or brakes. When that happened with car accelerating I had no brakes or steering. I crashed into my husbands car that was parked in spot next to me. I smashed his rear right panel. Car was going at such a speed my husbands car was pushed a couple of feet over. If his car was not there I would have crashed into the cement wall. As for my car I smashed left front fender head light and lower panel on front of car. Car immediately went dead. I immediately called insurance company and proceeded to call Hyundai. I had vehicle towed to auto body shop for repairs caused by accident. After body shop repairs were finished car was towed to Hyundai. This auto body shop had the car for 2-3 weeks. Hyundai technicians were called in to check. Hyundai's final outcome/decision was that there were no findings and they feel they are not responsible. I was then called to pick up car by manager. He claimed to have phoned me numerous amount of times, but this is false. I only received one call from him. Car is unsafe to drive since this is the second incident involving the same problem. Car was towed from Hyundai back to my residence and parked in the underground garage. I find this completely appauling and very upsetting that this has happened. This is not the response or service I expected to receive from a so called reputable company. This could have resulted in serious injury or fatalities. I feel Hyundai is totally responsible for this situation. They are not taking responsibity for this.

On Thursday, Feb 6, 2014 approximately at 2pm on a busy street. I was approaching a stoplight and as I was approaching stop light and attempted to put on brakes to stop. Instead of stopping the car the car sped up and didn't stop until I smashed into him. Car did not stop until collision occurred upon impact. I had no brakes!!!!! I smashed his rear bumper and cracked his license plate window. On Saturday, Feb 8th 2014 I took car into Hyundai dealer they insisted nothing was wrong with vehicle. I was asked if by Hyundai dealer if street was icy and the streets were completely dry. I called insurance reported incident, and with this collision there was 1300. 00 damage to his vehicle. Luckily there was no injury this time.

I bought my car in September 2013, it is certified pre-owned and came with the original 100,000 mile/10 year warranty, I purchased the extra electrical warranty. I was driving at about 40 mph and I noticed my transmission wasn't switching gears when I was accelerating and if I took my foot of off the brake the car wanted to stop, my brakes were locking up. There was smoke coming from the front drivers side tire and from the back passenger side tire and a loud noise. I pulled over, shut off the car and waited about 10-15 minutes until the smoking stopped and I turned the car on and began to drive home. I was only about 3 minutes from my home at that time. The transmission was continuing to demonstrate problems and the brakes to make a low rumbling noise. I called Hyundai roadside assistance right away to take my car to the dealership to be evaluated and fixed. I called at 3pm and they did not pick up my car until 9:30 pm. The next day they called me and told me my car was driving fine and they were going to check several other components of the car to confirm everything was in working order. A few hours later I called to get a status update on my vehicle and I was told that they discovered something wrong, they had conducted a test drive for the second time and discovered all of the problems I was initially reporting about the car. The service manager then told me he was not sure of the cause and that he would have to check several other things and I would need a rental car because he did not know how long the repair would take. I got the rental car at about 2 in the afternoon and was called at 5:30 and told me car was ready for pick-up and that they replaced the brake light switch. I went the next morning to pick up my car and drop off my rental at about 10am. I drove the car home and everything seemed to be fine, but at about 3pm had the same problem again.

I had begun to accelerate from a red light. The car in front began to stop again. When I pressed on the brake pedal, it would not go down, was not stopping the car at all. The car continued to accelerate on its own and I hit a van. The airbag went off, but the engine revved up, and the car shot forward again, hitting the other vehicle again. I tried putting the car in neutral and park. Nothing stopped it until I turned the vehicle off completely. I have the 'norm' seatbelt bruising, smashed my knee on the dash, and have whiplash as well.

While driving at 65mph on highway, there was a sudden loss of acceleration. It was as if I had let go of the gas pedal. Of course the pedal was at the same position and did not change. I let go of the pedal and repressed it and noticed that I got my power back. It does this intermittently for the last two months. No code errors appearing on dash or obd reading. Will happen at any given speed. Other issue is the driver side break light will work for a few weeks and then burn out, in which it will leave the remaining center and passenger brake light permanently on while the headlights are turned on. So it appears that I am breaking but I am not. Only temporary fix is to remove the left bulb from its socket.

The auto on several, sporadic occasions had an acceleration problem, while sitting still in traffic. While sitting still in traffic, the rpms would start to increase, going to 6000 rpms before I geared it back down and shut the engine off. I took it too the dealer on several occasions, they kept it couple of days each time, they told me, they could find nothing wrong, and go ahead and drive it, if it happened again, bring it back, sending me away in a unsafe vehicle. The last time, date mentioned above, a service technician test drove my car, the acceleration problem occurred, and he totaled out my vehicle. I was not notified until 2 days later that my vehicle had been in a accident. I was told, it happened the night before, I was notified on sept 13, 2013, that would have the accident occurring on sept. 12,2013, when in fact it occurred on sept. 11, 2013. I have searched and found on several occasions that this vehicle, did indeed, have acceleration problems, which the dealer had informed me, had never happened before. The vehicle, should have been diagnosed and the problem fixed, the first time, instead of the dealership, sending me away each time in a unsafe vehicle. Very unethical of the dealer, for telling lies about the car,and, the correct date the incident occurred, not notifying me for 2 days, that it occurred, and. Not fixing the problem, as should have been expected of them, the first time it occurred, and sending me away each time in a unsafe vehicle.

The contact stated while the vehicle was parked with the engine running the vehicle rolled away on its own and crashed through the garage wall into the kitchen of his home. The manufacturer was not made aware of the failure. The vehicle was not repaired. The approximate failure mileage was 14,000.

The contact owns a 2011 Hyundai Sonata. The contact stated that while sitting at a traffic light, there was an abnormal increase in engine rpms. The contact mentioned that he felt as if the vehicle wanted to lunge forward every time the failure occurred. The vehicle was taken to the dealer where the vehicle was test driven by a technician. The failure recurred while being test driven and the vehicle independently accelerated up an embankment, crashed into a tree and then rolled over. The technician sustained minor injuries and the vehicle was destroyed. A police report was filed. The manufacturer was made aware of the failure. The failure mileage was 36,000 and the current mileage was 44,500.

I was approaching an intersection that had a red light and stopped vehicles. I began to apply the brakes and slow down to under 10 mph. The car would not come to a stop. I had the brake pedal pressed as hard as I could and it did not stop. I did a google search on Hyundai Sonata 2011 brake problems and got 598,000 results. In a brief scan through those results I found 7 other reports of the exact same problem. This demands someone look into this now! I copied those web posting if you want them let me know!.

Car will randomly not start after parking it. Depress brake pedal through the floor, press start button, yet it says "press down brake pedal to start". This is the third time in three weeks. The first time I got it started after ~30 minutes. Second time, within ~ 5 - 10 minutes. This third time, I couldn't get it started. Had to call for a ride. Went back next day, tried again unsuccessfully for ~ 30 minutes. Called roadside assistance. They never came. After ~1:45 minutes, I tried one more time and got it to start. Each time, the steering wheel was turned strongly to the left and it felt locked. Each time I was eventually able to yank the steering wheel to the right and was able to get it to release. Felt like the hydraulics kicked in. Then, it would start each time. This didn't happen the first time I messed with the steering wheel . . . . But each time I was able to eventually make it do it. Until then, it had that locked feeling of no hydraulics. Other than this, no brake issues, no steering issues, no lights on dash, etc. One exception, first time coming down a hill, I had the esc (brake) light come on briefly. Very similar to other reports on this website.

Add on to odi # 10440320 I was driving and twice when I tried to stop to make a turn the engine kept overriding the brake and the car kept lurching ahead. I applied the brake peddle as hard as I could and the car would not stop. When I released the break peddle, the car started acting normal again. By this time I was way over the center line of the road and if there had been another car at the intersection I would have certainty hit them. This is the second and third time this has happened with this car and I believe it should be taken off the road before someone get killed. If I was pulling up behind another car at a stop sign and this happened I would rear end the car in front. If I was stopping at a pedestrian crossing and this happened I could run someone over and kill them.

The contact owns a 2011 Hyundai Sonata hybrid. The contact was driving 8 mph when the accelerator pedal was depressed and there was a noticeable delay before the vehicle would respond. The failure recurred twice. The vehicle was taken to the dealer and the manufacturer was made aware of the failure. The vehicle was not repaired. The failure mileage was 16,000 and the current mileage was 20,000.

After having 3 of 5 recall fixes performed, battery charging system warning light and sounds activated. Car lost power at low revs. Required giving full throttle to enable gas engine to kick in and gain enough speed to safely stay with traffic. After pulling over and turning engine off/on, problem seemed to resolve itself. Happened again in highway traffic while entering exit ramp resulting in a dangerous loss of power. Returned vehicle to dealership for repair. Dealership assured me that they knew what the issue was and that it would be repaired. 2 days later issue happened 3 times. Each time on the highway at approx. 65mph with nowhere safe to conveniently pull over.

I was pulling into parking space, had my foot on the brake, car was almost completely stopped, all of a sudden the car accelerated, traveled approximately 8 feet, the brake didn't stop the car. I hit the brick wall of a busy convenience gas station store, thankfully no one was coming out the door at the time. My first thought was the floor mat had interferred with the gas pedal, but am sure now that was not the case. When a representative of my insurance company called me, he stated that he heard that I had stepped on the gas pedal instead of the brake, this is not true, I am 100 precent sure. My husband was a passenger in the car and after we had calmed done, we discussed what had happened, he stated to me that the car was almost stopped and then just suddenly made a loud roaring sound and accelerated. Our car was towed to a Hyundai repair station and we are waiting to hear how much the damages are. Just the thought of having to drive that car again scares me, it was a very frightening experience, as it happened so fast and I had no control over stopping the car, other than my foot was on the brake and that didn't stop the acceleration. My hope is that this is investigated before any serious injuries or deaths occur.

I bought the Sonata 2011 turbo in 7/15/2011 the first day I test drove the car I asked the sales man if they aligned the car and he said it was done allready. Several months later I called them and said the car is out of control the steering keeps to the right and I am tired of pulling it to the left. Also the speed is uncontrolabel I have to take my foot of the accelerator in order for the car to slow down other wise I would be going 80mph on the fwy. It is very hard to keep consistency of the speed. I took the car back on October 21 the first time and they told me its normal. I was upset and told them that my 17 year old almost got into an accident due to not being abel to control the car at a turn. They ignored me and still insiste that the car was normal. I went back yesterday for the second time and test drove the car with their mechanic and he said that the car was fine and its all normal. I was never told that there was a recall on the car. I only found out about this today when I went back to speak to the manager for the third time is when they told me that all the Sonata 2011 have a pulling problems and it has no return memory after its done pulling so I have to get used to this cause thats what they all do. I am now very upest that I found this out on my own and that they didnt tell me about the recall and that me and my daughter are at risk of an accident at any given time. I had over 25 cars in the past and I know that this car is very unsafe to drive and if nothing is done about this someone will get hurt. I opened up a claim with Sonata customer service and I hope this will be taken care off right a way.

On the way to work this morning, my Sonata hybrid started beeping and "check charging system" appeared on the dashboard. My car suddenly started losing engine power to the point where my car would not move after the stop light turned green, leaving me stuck in the middle of a huge intersection with people almost hitting me. After restarting my car, it finally started to move, but repeated the same instance at the next stop light. This is a serious safety issue. I had to have my car towed to the dealership because I was not going to risk my safety and life. People need to be aware of this issue because if other vehicles are experiencing the same problem, someone could get into a serious car wreck which could be potentially fatal, if happened on a freeway.

Sonata 2011 horn and acceleration problems. People can not hear the horn. Also when I test drove they Sonata the test car had problems where there was accelerator problems. When I stepped on the gas the car almost quit, paused and they took off. This is dangerous and could cause an accident by not accelerating in time. This has happened on my car at least 7 times, accelerate, pause or hesitation the motor kicks in. When I asked the salesman about it at the dealer he told me the motor on the test car was probably cold. This happens when the car is warmed up. This is very scary when you pull out in traffic. Also the horn is a joke. You can't hear the horn and it needs to be replaced.
