“While driving the car, the engine loses power. Engine and electrical systems still running but when pushing the accelerator, you get no response. This has happened twice within the last 5 days. We have called and setup an appointment with the dealership, but the earliest appointment was this friday. Luckily we were not in heavy traffic or a serious accident could of occurred.”
NHTSA complaint #10320928, filed 2010-03, 33,000 miles“Lost complete ability to accelerate on highway traveling at 70 MPH. No warning, happened twice more before I got it back to a dealer. Car did not shut off but would not accelerate. Restarted after I managed to get off in the breakdown lane. The car would go another few miles and konk out again. I immediately went to the closest Hyundai dealer. They said it was a throttle position sensor. Could really have been fatal.”
NHTSA complaint #10326528, filed 2010-04, 43,570 miles“I was subjected to a sudden acceleration last night while driving my 2009 Hyundai Genesis 4.6. I left a full stop and sighted another car speeding toward a stop sign coming from my left. To avoid being broadsided I swerved to avoid and my accelerator jammed. I sped across the street and into a landscaped area. I hit a tree at that point which brought my vehicle to a stop. The driver side air bag deployed and I was wearing a seat belt. I sustained some impact injuries that appear to be of a minor nature. …”
NHTSA complaint #10667447, filed 2014-12, 29,000 miles“While driving at 65 MPH in 4 lane I-95 rush hour traffic, the check engine light and the ESC light both came on and the car would not accelerate. Pressing on the gas pedal had no effect. I turned on flashers and drifted my way through 3 lanes and pulled over and restarted the car. The check engine light came on but not the ESC light. The car ran a bit rough with the check engine light on. The exact same thing happened the next day. I took the car to the dealer, and they replaced the throttle position sensor. …”
NHTSA complaint #10516011, filed 2013-06, 85,100 miles“This has been an ongoing issue, I have filed at least 4 complaints concerning a soft pedal issue. The dealer has inspected my vehicle recently as well as Hyundai america and I am still awaiting a response as to what was found. The vehicle was inspected on 1/22/2014. Note on service invoice states dpsm has been out to drive and inspect vehicle. No person from parkway Hyundai can give any further information. This is a matter for Hyundai motor america. It has been 5 months since the inspection and hma has still not contacted me. …”
