| Description of the problem | I own a 2004 hyundai xg350l that is having accelerator issues. On several occasions, while stopped / idling, or slowing down, the vehicle will suddenly accelerate. This is while the brake is being applied. I can be setting at a stop light or stop sign with foot on the brake, not the accelerator, ( i do not drive with both feet like some people incorrectly do : ) and suddenly the car will rev up and try and accelerate forward. In other cases, i can be slowing down with brake applied, and again, the vehicle will accelerate forward. I have to really "mash" the brake to prevent the car from accelerating forward. Once i bring the car to a stop, and the car is still trying to accelerate, i will have to put the shifter into neutral, and turn the car off. I can let the car sit for several minutes, restart it, and it will usually be back to normal. Luckily, i have not had any accidents as a result of this issue, as some of the other people who have posted complaints have...... Yet. On several other occasions, it has been just the opposite.......... I will be driving down the road at any given speed, and suddenly the car will just stop accelerating & go to an idle. You can press the gas petal to the floor, and the accelerator will not respond. The car will remain running, but will only idle. I once had to drive approx. 8 miles, in the emergency lane, at an idle speed of about 5-10 mph to reach my destination : ( these where once sporadic occurrences, but now happens on a daily bases. I just recently replaced the throttle position sensor, and this did not fix the problem. I have learned that it could be caused by the "accelerator petal position sensor"; hyundai pn:35357-3b011. There is obviously a serious issue w/ accelerator problems w/ the xg350, sonata & santa fe, that hyundai needs to address. I have read of cases w/ hyundai acceleration problems that have caused deaths. |
