Tl* the contact owns a 2004 hyundai elantra. While driving various speeds, the throttle positioning sensor failed on more than one occasion. Upon deceleration, the vehicle accelerated without warning. The contact depressed the brake pedal and the vehicle accelerated rapidly. In addition, the contact described the brake pedal as having a "dead spot", thus the vehicle accelerated on its own after the brake pedal was depressed. On one occasion, there was an increase in the rmps that was directly related to the worn position sensor. The contact independently replaced the positioning sensor. Millennium hyundai (265 north franklin st, hempstead, ny 11550) was made aware of the failure and acknowledged the failures. The vehicle was not diagnosed. The manufacturer was made aware of the failures. The failure mileage was 105,000.

Sudden acceleration incident I am the son of the car owner. I was driving the car. The incident occurred about 8:30 am on june 17, 2010, in bethesda, md. I was exiting the giant food parking lot and stopped for traffic along old georgetown road. The car stopped but then all of a sudden inched ahead. I pushed down harder on the brake; heard the engine racing; saw the tachometer go past 6000 rpms. I immediately put the transmission in neutral. The engine was still racing. I turned off the car. I started the car and the same thing occurred, the tachometer went past 6000 rpms. I turned off the car. I rolled the car to a parking space. I called my wife. A few minutes past, and I started the car again. This time it operated properly. I took the car to fitzgerald auto mall that evening, for next day service. The technician reported hearing of such incidents when "after market oil filters were used on both hyundai's and on subaru's." I recently had an oil change on that car. The gaskets are apparently not the same as on the factory oil filters. So the oil and filter was changed. They also found a mis-fire code in the computer. So the plugs and wires were changed. There was no vacuum leak code in the system.

I was driving a hyudai elentra rental car and I was stopped at a red light with the car in drive and my foot on the brake, and the brake was not holding the car back and the car was drifting forward a little into the intersection. I put the car into neutral and you could hear the engine revving very fast even though I did not have my foot on the gas pedal. I told the attendant when I returned the rental car that the brake wasn't holding the car back at a red light, but told her that I did not know what the problem was. She said that she would take the car out of service to be checked. The following week in the march 9 USA today there was an article reporting that some toyota camrys, camry solaras, and lexus es 300s surged forward with no reason. I believe that this is what occurred in the hyundai that I was driving. I have called avis to give them the car number that I was driving so that they can take the car in to be checked. I have listed the car below as a 2004 model. I believe that it was a 2004 because it was new and had low mileage. A question below asks whether it had cruise control, but I don't know.
