general problems of the 2005 Hyundai Santa Fe

Started engine. Placed the automatic transmission selection into reverse. The engine immediately had an unintended acceleration to perhaps 2500 rpm. Operator immediately applied very heavy pressure on the brake pedal to stop any rear direction movement. Operator immediately moved the shift lever back to the park position, shut off the ignition and restarted the vehicle. After restarting, everything was back to normal. This had also occurred one other time in September, 2013 under the same circumstances. Operator initially assumed that perhaps his foot had moved to the right and was depressing both the accelerator and the brake at the same time, but when attempting to see if this could be done, operator could not replicate. It is assumed the throttle sensor locator may be faulty. Very disturbing when this happens and could easily result in property or personal damage. .

Sudden unintended acceleration. While driving my vehicle, the car "lurches" forward and the engine "reves" up. I've had it to the mechanic numerous times and they can not seem to find a reason for this to be happening. It is a very scary situation. I have 2 small children and have become fearful when driving my car. This happens on the highway as well as regular street roads. I've seen many forums on line with the same complaints from other Hyundai owners. I really hope that someone looks into these complaints.

On a frequent basis I can smell gasoline fumes in the vehicle interior while driving. When I asked the dealership about the fumes they acted like it was normal, and did not investigate the problem. If the fire wall around the vehicle is intact how can fumes get into the vehicle interior? they did suggest it may be caused by an air lock in the system.
