This has occurred three separate times, but this report explains what happened during the most recent occurrence. I was driving at 40 mph. The car in front of me hit their brakes, so I lightly tapped my brakes to slow down. When I tapped the gas pedal, the car would not increase speed. The check engine light, oil light, and battery light each turned on simultaneously. The car then stalled completely, but the lights remained on and the car didn-??t lose power. I hit the brakes (which were now hard to push down), hit my emergency flashes so that the car behind me would pass me, pulled over to the side of the road, and then I turned off the car. When I turned the car back on, 30 seconds later, all of the lights were off and the car started with no issue.

The piston rings do not seal leading to increased oil consumption and very low oil. My safety was put at risk because when I pulled out into traffic that was going at a high speed I could not accelerate. There was no warning or indication that this was going on prior to this incident. Yes this has been confirmed by a Hyundai dealership and the component was inspected. There was no warning sign before this incident.

While driving over the last month, the car shuts off with no warning. There are no check engine or other lights that come on once it shuts down. There does not appear to be any consistency in the occurences, sometimes while idling, sometimes while driving 40 mph. Up until recently, the car would restart once I put it in neutral, but it now does not restart right away.

- Little Compton, RI, USA

I was driving the vehicle normally down the highway. When I exited the highway, I came to a stop light and made a complete stop at which point the engine stalled. I restarted the vehicle, the check engine light appeared, but I couldn-??t get it to register any RPMs and I was left stranded in a busy intersection until help arrived.

- Davison, MI, USA

my car will stall randomly at stop signs and red lights with absolutely no warning. it-??s super dangerous and has almost caused a wreck. i have taken it to mechanic and no codes are being thrown and it-??s showing nothing is wrong. it-??s a matter of time a accident happens and someone gets hurt. I would definitely like to figure this out!

2014 Elantra driving the car in town at slow speeds, usually around 15-25 miles an hour, with rpms at about 1250. First noticed an issue with extremely jerky driving, but added gas and the problem went away, and I thought it was a one-time thing. About a week later, it happened again. I set an appointment to the murdock Hyundai of murray Utah to solve this issue that was putting my family and my security in risk. On June 18th around 6 pm, the did a diagnostic check in the dealership and then, they recommended me to clean my gas injectors, to do a tune-up, to do an alignment and to add new four tires change since they were totally damaged., some kind of Hyundai solvent cleaners for the gas engine. All of the services had a total of $1043 dollars. I thought it was all it needed but not it was not. A few days later, the car started to have the same symptoms as before, losing power again, engine slowing down and bad gas mileage... I set up another appointment with the dealership.

08-26-16 while pulling into a parking space at a public park while doing less than 5 miles per hour, I experienced rapid unintended acceleration, plowed through a fence, sideswiped a tree, went off a grassy median back up onto a grassy median and then bounced off of that before the car finally came to rest. My brakes did not work and I had no control over the vehicle. It is a miracle that I am not dead as the park is on a very busy 4 lane road and is usually full of children.

I am the owner of a 2014 white Hyundai Elantra, at present the odometer is reading 6,800 miles. On Tuesday, December 9th, at approximately 5:25 P.M. while driving my 2014 Hyundai Elantra at a slow speed (approximately 10-15 mph) in a shopping center parking lot located at 10100 w. sample road, Florida, I experienced a sudden and unexpected acceleration, which caused a severe crash involving two other vehicles. My vehicle suddenly accelerated which thereby caused me to lose control of the vehicle and collide with two parked cars (an SUV and a sedan. Even after colliding with the SUV I still was unable the stop the vehicle which was traveling at such a high rate of speed that I collided with a second vehicle. It was only when I put the car into the park position did the vehicle come to a stop. At no time did the cars airbags deploy. I am beyond distressed about this accident. I am a safe driver and have never experienced an accident such as this before. Aside from my physical and emotional injuries, my sister suffered several injuries when she arrived on the scene. This has just added to my distress and disappointment about the accident. When I purchased the vehicle I was assured that this was a safe car, however, I have looked at the NHTSA website and there are multiple complaints about the Hyundai Elantra, including several sudden and unexplained acceleration crashes. I intend to file a complaint myself. The preliminary estimate of the damage to my car is over ten thousand dollars and now I face selling the car because there is no way that I would feel safe or comfortable driving it again. I have two young grandchildren that visit me frequently and I would never take the chance of having them in an unsafe car. I expect that you will be eager to conduct a full investigation into this matter and conduct a full inspection of my car as soon as possible.
