I has recently traded in my 2012 Hyundai Elantra for a 2014 Hyundai Elantra. The 2014 had started doing what the 2012 did occasionally, accelerate when I released my foot from the gas to switch to the brake to begin slowing down for a light. After I've applied the brake and I'm coasting before I need to apply it again, the car will accelerate. I used to think it was my imagination, then I read others confirming it does happen. Lately I've also had an issue with the car accelerating when I do touch the gas, the engine revs up and bolts forward like I floored it, but I only lightly touched the gas. I'll be bringing it to the dealer soon for these issues.

I was on a highway driving the vehicle (a 2014 Hyundai Elantra) at highway speed when it inexplicably "stalled" for lack of a better term. I quickly lost speed and could not accelerate despite the fact that I was pressing the gas pedal all the way to the floor at one point. The vehicle simply did not respond. There was plenty of gas in the vehicle, so I had not run out of gas. The vehicle appeared to have shut off in the middle of operation. This resulted in a major accident on a highway where I, along with the other occupants within the vehicle, sustained significant injuries. Notably, no airbags deployed--even though the vehicle was struck several times from different angles and sustained heavy damage, including being crushed in from the rear.

My low fuel indicator light had just turned on. Was going up a very slight grade and the car stopped in the middle of the road.

I took my foot off the gas pedal to slow the car down as I was approaching another vehicle in front of me stopped at a red light. My foot was neither on the gas nor the brake and the car accelerated as if I was pressing the gas pedal.

I was driving my 2014 Hyundai Elantra (that I had only had for 3 months, had 1,500 miles on the car) home from the airport, had my cruise control set on 55 for the previous 30 minutes, and I noticed the car in front of me was braking. Naturally, I pressed the brake as well to slow down, but the brakes did not work. The brake pedal was hard as rock and would not press in at all and therefore I could not slow down and cruise control did not disengage. I kept trying to press the brake as hard as I could, but the brake pedal was hard and would not work and cruise control kept accelerating. I pressed the cancel cruise control button on my steering wheel, but that did not disengage either. Just has I was shifting my car to neutral, my car rear-ended the Lexus in front of me. After my car struck the Lexus (my foot still on the brake pedal), I felt the brake finally press in and I was able to slow down and pull off the side of the road. The brake malfunction is still under investigation, but upon my own investigation, I found a recall of Hyundai Elantra year models 2007-2011 for this very issue that caused my car accident.
