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.

Have 2004 elantra w/ 77,000 miles. Check engine light came on while starting car in am. Car has no symptoms of bad plugs,02 sensor, or catalytic conv. Issues. Runs fine, no different. I have the car checked diagnostically and they said the 02 needed changing and new p;lugs / wires. The wires/ plugs arent due for another 30k miles we thought, and the car running fine! Was waiting to have this service done as we were given a $613.00 quote! In meantime the check light went off and car running fine! It had just had theoiil changed and a new air filter when this occured, and new gas. It seemed when the car was almost out of gas( I let it run low) I put a better grade from another station and this is when the engine light went off! Why would this occure if it is needing plugs, 02 sensors??? Also no trouble, roughness or idle trouble, or power loss with this car. Could it be bad gas, airfilter issues?? Please help!!

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.

On 11/26/07 the car got overheated, engine check light came on and engine shut down on the highway, coolant leaked out, car towed in. Bridgeport key hyundai replaced coolant temperature sensor on 04/11/08 the car stalled on the highway without engine light coming on, coolant leaked out, engine failure caused a collision with another vehicle from the back. The car was towed in, it needs engine replacement. We believe the coolant repairs to be defective. Dealer denies our claim and blames engine failure on poor maintenance. I have read a number of reports about hyundai engine stalling/coolant leak. In addition ABS/tcs light has been coming on with the brake pedal vibrating and making noise. Car wouldn't stop as requested especially on wet, icy surface. Dealer cannot locate the problem please investigate both defects.
