I was pulling out of a parking lot today going about 20mph when my car started speeding up. I started braking, but the engine seemed to just want to go. I was coming to a stop sign and cars were coming so I just turned off the switch and it stopped. When I restarted it, it seemed normal and I drove very carefully home. I am going to try to rent a car till this gets checked. It scared me to death and has never happened before.

Car accilerater gets stuck and will accelerate when car is first started, whether stationary or in motion. Gas pedal will stick. Seems to function normally after the car has warmed up. I tapped on the gas pedal to see if it would un-stick and it accelerated at very high speed and was stuck until I pulled over and turned the car off. Acceleration dropped down slowly after I turned the car back on and left it in park. Resumed normally after.

The contact owns a 2009 Hyundai Elantra. The contact stated that the vehicle independently accelerated several times without warning. In addition, while parked in a driveway, the vehicle surged with a high rate of speed and independently crashed into the driveway. The driver was not injured. The vehicle was towed to a collision center and then towed to the dealer. The dealer diagnosed that the accelerator pedal and springs needed to be replaced because they were sticking.

This has happened to me 2 times, upon driving the car it randomly accelerates all on its own. Its as if someone is putting the pedal to the metal and trying to brake at the same time.. slamming on the brakes only slows it down but not enough then I proceed to pull the emergency brake all the way which only assits a little.. so at this point I am at the complete mercy of a vechicle with a mind of its own.. im stuck driving a car that wont stop for 3 exits in the breakdown lane and 2 seconds away from calling the state police for assistance... putting it into neutral didnt stop it either it kept going!!! took it immediatly to the Hyundai dealership and after putting 100 miles on it to try and recreate the issue ( which thats a very dangerous issue to recreate ) it didnt occor for them so I was handed my keys and told to drive off in a possible death machine with a mind of its own. I take my car for the scheduled maitinece and do my part so Hyundai should not want thier loyal consumers driving such hazards.... ive read several simailar stories and people have had no luck in getting this matter resolved thier soulution was to get a new car... if only it was that easy.

Traveling on interstate, using cruise control (as I had the day previously and for approx 150 miles this day) attempted to stop vehicle due to vehicles slowing down in front of me. Could not get out of cruise control - in fact, the vehicle accelerated -- and brakes did not work. Fortunately, I was in the right lane and was able to exit the highway without hitting the guardrail (approx. 20 feet away when I left the highway), traveled at a high rate of speed down a slight embankment and into a field, where fortunately there were no obstacles, and was able to stop the vehicle approx. 500 feet from leaving the highway. The engine was still running, now at a normal rate. I attempted to return to the interstate but was not successful due to the embankment. I drove through my previous tracks in the field and was able to get onto a nearby exit ramp. The vehicle functioned normally after that. Please note, this vehicle has a manual transmission. I did not attempt to engage the clutch to put the transmission in neutral because I had both hands on the steering wheel trying to maneuver through the field, which was quite green, actively growing, and approximately 15 inches high. The crop scraped the underside of the vehicle, which is now in the shop waiting to have the new part replaced. The mechanic will check for damage on the underside. I am not sure if the vehicle stopped B/C the brakes finally kicked in or the vegetative growth slowed me down.
