My car revved to between 4 and 6 thousand rpms when I was parking in my work parking garage. In the process I ended up hitting two SUVS and did over $5,500 in damage to my car. I took my car to our Hyundai service to have the engine looked at and they couldn't find anything wrong with it. On Friday, May 15 as I was driving home from work on rt 70 at the top of braddock mountain my car revved again for no reason. Luckily I wasn't in traffic when the rev happened. This rev has also happened when my husband was driving the car.

Driving down the freeway, we heard a clicking sound then a loss of power, but it came back after a few seconds. The clicking and loss of power happened again the next day while driving on a surface street, again for just a few seconds. The next thing that happened while accelerating onto the freeway, a red light flashed on the instrument panel, but did not stay on, unable to determine the light at that time. The next thing that happened was a puff of smoke came out of the tail pipe, which at that time we decided to take the vehicle to the dealer. The next day, the dealer informed me that the vehicle had no oil in the engine, and that it had goop in the oil pan. The dealer then said that the rings are burnt up and that the engine needed to be replaced. We had no warning that the engine had no oil - no warning lights stayed on. We also have a bluelink report that says everything is operating as normal.

I was driving on road (around 45 mph) and the car stalled and stopped abruptly. Managed to safely pull over the vehicle to the side of the road when I realized the car started to lose power in spite of me trying to accelerate and keep it going. Seconds before car stalled, check engine, oil, eps and battery indicators lighted on. Towed the car to the dealership and they had the car for a week, checked and assured us the car was fine to drive but the incident occurred again while I was driving (around 45 mph) to office on 14 April 2015 and the car odometer reading was showing18385. Same as before check engine, oil, eps and battery indicators lighted on and car stopped abruptly. Would have been life threatening if it would have happened like 10 minutes earlier as I was driving on the highway. This time the car was towed to the dealership again, and was later told that the engine is faulty and needs to be replaced with a brand new engine. Car is still in the dealership.

In rain car looses power. Wants to cut off.

I was pulling up to a stop light and my car made a jerking motion, as it had did one day prior as well. I looked at my dash and the eps light, battery light, check engine light, and one more light came on. I tried to drive the car forward and it began to roll back. I turned the car off to try and restart it, but the break would not push down for me to turn it back on. The car was towed to a dealership where I showed two service technicians the photo of the dashboard that I took, and both said that my engine had cut off. They kept the car overnight and drove on it to try and recreate the problem, along with running multiple tests, and nothing showed up.

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.

Have the 2013 Hyundai Sonata turbo and was told when I bought it that it would appear to drive differently. It races before it shifts to the next gear and at times it seems to pick up speed when I am not on the gas. Have called and asked to be told that the RPM system has to get as high as 4 before it shifts - that doesn't seem right and it makes the steering difficult at times. The acceleration is poor and I only have 11,000 miles on it but I'm ready to trade it in - not sure if a turbo is suppose to really drive this way and can't seem to get an answer from the dealer when I call. Their service hours are not good because they're open while I work. Does anyone else have this problem?

When braking, the car self-accelerates. There is no predicting when this will happen- sometimes it does, sometimes it doesn't. this has occurred approximately twenty times when I have started/stopped the car while parking and also once on a busy highway when I was unable to stop for a red light. When this happens, my foot is on the brake, but the car accelerates. The car has been to the ciocca Hyundai dealer in quakertown, pa three times. They've kept it as long as three days. They tried to duplicate the problem and I was told it did not occur. They've told me that they've never heard of a problem like this. They checked out the car and told me that nothing is wrong. The problem has been reported to Hyundai- regional case #6004610 and case #6342874. After filing there's nothing that can be done besides file the report with the regional representative. I've been fortunate that no one has been injured so far. My family members will not ride in the car with me. The car currently has 5,700 miles on it. It is a killer car- an accident waiting to happen.

First occurrence I was sitting at a stop light and started to move, car lunged forward with an unattended acceleration. Second occurrence I was at an intersection waiting to proceed through, stepped on the gas pedal and car did not accelerate. Third occurrence was in Kansas and my brother was driving. It surged again and we both noticed it. Fourth occurrence resulted in an accident in ringgold ga on 10-28-13. I was starting to park in front of the church, the car surged fast and I tried to stop it with my brake, but it continued into the concrete building resulting in my serious injury and $6,000 damage to my car. With great concern about this car, I went to the dealer and asked if they had ever heard of this before and they said, "no".

I was driving a new 2013 Hyundai Sonata in a parking area, approaching a parking space for a straight-in parking facing a building. My speed was about 10mph. I brake continuously to slow down and stop, but nothing happened. The car went through the parking space and crashed into the brick wall facade of the building. The air bags did not deploy. The brick wall was not damaged. I had about 5 minor bruises on my right leg, and two below umbilicus (seat belt area). I also suffered from fright and emotional distress. A nearby pedestrian was cut on the ankle by crash debris that projected out sideways from the impact. The debris also scratched a car in the adjacent parking space. My insurance adjustor said that the car was a total loss from the damage.

Purchased 2013 Hyundai Sonata gls at streetboro Ohio Hyundai dealer new in mid June 2012. Vehicle seemed ok but at about 1500 miles idle became rough particularly at idle in drive at lights and stops. Took in to dealer and was told after 4 days in shop that problem was familiar to the dealer and an engineer was being called in to figure out the solution as no codes were stored in computer.I left the dealer after being told car is within Hyundai specs but was running strange. The dealer seems to be avoiding doing anything to admit there is a issue and refused to allow a service tech to ride along with me to experience the problem. They also refused to let my salesman go in a newer model with me to see if any other vehicles had same issues.I wrote to Hyundai corporate and was given a list of other dealers to go to.as the problem has begun to get worse the idle will now rev and then decelerate the vehicle when coasting and I can imagine what this braking action will cause the vehicle to do as the weather becomes worse and snow appears. This seems to be a growing problem with the Hyundai models from the recent Hyundai forums posts.
