I was driving on the highway when my car threw a crank rod. In doing some research I see that this has happened on numerous vehicles having faulty bolts on the crank rod cap. There has been no recall but is an ongoing issue with many owners.

In the span 2 months, there were 2 occasions where my car would not start. I thought it was the battery and had someone jump me and it still wouldn't start. However, after trying several times, car would finally start. One other time I pulled into a store and when I came out, my car wouldn't start. After several attempts, it finally started. Then on November 28th, 2014, my boyfriend was driving my car and it just stopped running. I had it towed to an independent mechanic and they stated that the engine had seized. I did not have any warning or indication that anything was wrong. Today I have to have it towed to the Hyundai dealership and they will let me know the exact problem and if it is covered under the warranty.

As I began driving my 2011 Hyundai Sonata that morning I heard a rattle whenever my rpm would reach between 2-3k. I contacted my local Hyundai dealership and made an appointment. Today 11/20/14i was told that my engine needed to be replaced. My car was previously in the dealership late September 2014for an oil change and also due to a small knock/bang as I accelerated. The technician found the knock to be a support hitting against the firewall. Upon tightening said support the problem went away. The car was reportidly teat driven by the technician numerous times to conclude that the problem was fixed. Oil change was done as usual and my car was given a clean bill of health (only a recommendation of brakes getting low).
At approximately 5pm on October 10th 2014 I pulled out of a parking lot in harrisburg, nc. When the car reached 15 mph it did not shift (the car is equipped with automatic transmission with shiftronic manual controls) and I had to shift the car manually into second gear and each successive gear. After doing so I noticed the car had turned off while driving. I was able to pull off the road with no incident and restart the car. The following day, I noticed clicking under the hood and took it into the dealer. After their examination they determined the engine had a defect. They are replacing the engine.

While driving on the freeway the car started accelerating on its own. Tried pumping the gas pedal to release it, car still accelerated. Brakes did little good. Was able to down shift into first gear, then into neutral and utilizing the emergency brake was able to get the car slowed down enough to cut the engine. Some problem happened immediately when I turned the car back on trying to get it off the freeway off ramp. Was able to stop safely in a parking lot without hitting anything. Had the car towed to the dealership, where they said it was a problem with the throttle.

I was turning on to smith switch road in ashburn virginia from waxpool road. I reached to turn on the emergency flashers due to bicyclist on the roadway and I bumped the starter switch for the car and it shut the car off while it was still in motion. This caused the steering to be heavy and brakes very hard to use. Luckily I was able to coast off the road without an accident. I had to stop the vehicle totally and put back into park before it would start again and it would not start again while it was coasting. I tried and it didn't work.

The contact owns a 2012 Hyundai Sonata. The contact stated that after parking and turning off the vehicle in her residential garage, the vehicle started rolling backwards. In an attempt to stop the vehicle the contact fell which caused her to scrape her chin needing 10 stitches. The contact was taken to the emergency room. The failure mileage was 39,000. The consumer stated she and the police attempted to piece together the scenario, that the vehicle was not in park, when she turned it off. The consumer stated the vehicle could be put into any gear, and it could roll, whether it was on a flat of hilly surface. Updated 08/20/14 updated 8/27/cn.
In may 2014, while driving at about 40 mph, maybe 1200 rpm, my engine suddenly accelerated to 4500-5000 rpm, without a simultaneous rise in speed. A week or two later, the car did the same, under about the same conditions. The dealer could find no faults or codes, and could not duplicate the occurrence; not surprising since it was sporadic. The problem continued, with considerably more frequency; almost daily. Again I took it to the dealer in late July (mccafferty Hyundai, langhorne, PA), and while a technician was driving with me, the engine raced again. They told me that there was a tech bulletin on this problem, and they would repair the car. The problem was in a module and needed recoding. At least that's what I thought they said. That repair seemed to cure the problem, until September, when a single occurrence happened. I though this was maybe a fluke, but the problem happened several more times in the following weeks. Today, 11/4/14, after several days in the dealer's shop, an insurance service tech said he could find no problem. I am now afraid to drive this car. While the car does not accelerate, maybe it's just a matter of time when the racing engine will cause severe acceleration and a subsequent accident.
While attempting to accelerate from a stop the vehicle got to 30 to 35 mph and would not go any faster despite pressing gas pedal and rpms went up to 7 and 8. After pushing gas pedal several times the car will finally increase in speed which is very concerning given I drive on an interstate. This has happened 3 times in past 4 months and same exact thing at 10 mph and rpm went to 4 and 5 and car would not increase speed. I stopped vehicle and accelerated and then it operated normally. Dealership has been in unable to duplicate it and has questioned me several times about driving with two feet which I do not do and laying purse on console against shifter which I also do not do. 3 of the 4 times it happened it was at the beginning of my drive within first mile or so. 1 time was near end after about 20 miles. Purchased car used with 18000 miles on it and did not drive on interstate from July 2013 until March 2014 on regular basis.
When I applied break my rpm idle goes up. I don't know if that is safe I show in other car rpm goes down. I took to dealer got oil change. And I asked why this happens. He told me to chack eco system. I chack eco system it was on off postion. I ask him when I bought car I never show rpm go up when I hate break. There no engine sing comesup on dashboard either. This really safety concern for my family. Rpm should not go up when u hate breaks. It's should bring rpm down. Rpm should go up when u hate gas padel. I get this. But when I go to any speed. And tried to applied break it should drop rpm should not go up.

My vehicle hyndai Sonata 2011, crashed into a parked construction in a parking lot at the speeds of up to 30 mph. The crash damaged basically the whole front side of the driver side and damaged the front two wheels. The front windshield was damaged as well with cracks on the shield and it also knocked out the rearview mirrors. I was in the driver seat when the crash happened and my head crashed up against the steering wheel, which left a little soreness. What I was wondering is with such an impact and such damage, how did the airbags not go off?. My head slammed pretty good up against the steering wheel and a little more impact I could've been severely hurt. So I just want to ask why did the airbags not work?.
While driving in the fast lane of a 3 lane freeway on a steep upgrade, the car suddenly and without warning lost a huge amount of engine power. The effect was similar to no longer pushing the accelerator pedal. This caused the cars in back of me to slam on their breaks as well as scaring me as I had no idea what happened. This has occurred twice so far. Hyundai America (ha) is well aware of the problem and from what I have discovered after viewing ha forums, this problem is specific to the Sonata's with the 2. 0 turbocharged engines including model years 2011 - 2014. Not only is the problem a result of a poorly designed waste gate control rod, it is a huge safety issue. Inexperienced drivers as well as experienced drivers are going to be harmed. Ha is well aware of the problem and has decided not to cover the repair expense after 60,000 miles. Apparently, a functioning turbocharger is not part of the engine! please insure the ha not only fixes this safety hazard but also reimburses owners for previously charged repair expense. My car was repaired around 56,000 miles andat 67,000 miles, the problem is back. Thank you.

Unintended acceleration, had to slam on brakes and put car into neutral in order to prevent shooting into a intersection of oncoming traffic. The car immediately threw a number of codes, and a engine control system condition code, check engine code. . . . Dealer tells me when unloaded off the tow-truck that the brake pedal went to the floor, after 6 days of having the car the dealership service manager is telling me no problem could be found due to not being able to reproduce the problem.
The car would not start, battery is three weeks old. The car was brought in to the dealership by tow and was repaired and returned to me on 11/11/2013. I was told at the time that it wasn't the starter,it was the starter lever. The evening of 11/11/2013 the car wouldn't start on the first try , but did after the second. On 11/12/13 the car failed to start until the fourth try. I called and the dealer said to bring it back in, I did on the morning of 11/13/13, in preparing to leave for the dealership from my work location the car again failed to start three times and finally started on the fourth try. No car in my family has ever had a starter issue like this in a car that is less then three years old.
