2005 Hyundai Elantra Owner Comments

problem #12

May 152013


  • 78,000 miles


Very sporadic (6-8 times over six months) continued acceleration at 2500+ RPM when foot is removed from accelerator pedal. No codes ever set; no information provided by engine history. Test drive by a trusted mechanic and a service rep from local Hyundai dealer (most recent test drive 10/30/2013) could not reproduce the defect. Test drive by me with the same service rep same day nearly resulted in severe crash. Turning right out of dealership onto md 198 and accelerating up to 3300 RPM toward changing traffic signal, vehicle failed to slow when foot removed from pedal. Brake applied with great effort and virtually no response. Steered into right turn in front of cross traffic from left and shifted to neutral to regain control of brakes on right shoulder. Engine raced in excess of 6000 RPM with no load for 1-2 seconds until I tapped the accelerator pedal twice. Engine returned to idle speed. This uncontrolled acceleration happened twice more before we got back to the dealership. This is an extremely hazardous condition and warrants a full investigation. The vehicle is currently at the ourisman Hyundai dealership on fort meade road, laurel, md.

The contact owns a 2005 Hyundai Elantra. While driving approximately 5 mph, the contact depressed the brake pedal but the brakes would not respond and the vehicle continued to accelerate independently.

The police reported to the scene and a report was filed. There were no injuries. The vehicle was towed to an auto body shop but was not repaired. The approximate failure mileage was 56,000.

On December 10, 2011, I was turning from northbound gary av. Onto eastbound lawrence ave. At approximately 5 mph. While I was turning my accelerator stuck the engine sped out of control to at least 40 mph. I swerved to avoid hitting a truck turning onto gary and my car went over the South curb.. and my attempts to break were failing all this time... I crashed through a fence into somebody's back yard went down hill about 50 feet and ran into a tree. I then turned off the ignition. The airbag did not deploy. The investigating bloomingdale police officer started the car and the accelerator was still stuck in the wide open position. The body shop personnel also confirmed the accelerator was stuck.

Elantra 4-cyl

  • 18,300 miles


While driving very slowly in a parking lot, just after stopping at a stop sign and while gently pushing the gas pedal to make a right hand turn, my Hyundai Elantra suddenly accelerated at an undesirably high rate of speed. Although I removed my foot from the gas pedal and firmly pressed the brake, the car continued to lurch forward while the RPM revved loudly. I immediately put the automatic transmission into park, and the car stopped moving and a few seconds later the engine idle returned to normal. Fortunately, no cars or pedestrians were in front of me, although many shoppers standing nearby stopped to watch as they heard the excessive roar of the engine. I drove the car to the Hyundai dealer, and he found no record of the incident on the car's computer software. This incident of sudden uncontrollable acceleration happened this one time and has not happened since. I am reporting this to make you aware that this sudden acceleration problem is not limited to Toyota.

Traveling on the freeway the vehicle suddenly accelerated to 80mph and would not slow down it continued for about 15 miles before I put the veh in neutral and turned off the key, (the service dept at the dealer advised me to do that).at that time smoke poured out of the engine and I thought the veh was on fire. I called 911. I was able to avoid a collision however the policeman asked me to move the car and when I turned on the key it started at full throttle I was afraid so I got out and refused to move the car. When a police officer moved the car it again started at full throttle. They towed it to the dealer, they said there is nothing wrong with it. I am afraid to drive it and I want a different veh or a refund.
