After driving my 2003 hyundai elantra gls about 60 miles on aug. 18, 2010 my check engine light came on. I took it to be serviced at a shop and waited until the next day for the purge valve and the control valve (both acquired directly from the manufacturer) to be replaced. 2.5 hrs later, approaching a stop sign, my car began accelerating despite my repeatedly hitting the brake. I put the car into n, pulled up the emergency brake & continued to rev/accelerate until I turned the key off and cruised into an empty intersection. About a minute later, I turned the vehicle back on and waited to see if I could feel or hear anything odd. I attempted to drive the vehicle again and the exact same thing happened after driving about 0.5 mile. I contacted the auto shop that replaced the valve and was told it did not sound like it was associated with what was fixed but to let him know after I had another shop look at it (since I was 1.5 hrs away). I called the tow truck driver and explained the situation. While waiting for the truck, about an hour later, I started the engine so my father could listen to the engine and my engine revved to 7000 RPM just turning it on. It was in park at the time. I immediately turned it off and didn't attempt to start it again. Upon the tow truck driver's arrival, I explained what had happened each time. He started the car, reversed it, put it into drive and it accelerated on its own a third time while in drive. He turned the engine off and loaded it onto the truck. Upon investigating any causes, he told me he cleaned out the throttle and it was running fine. He test drove it several times and said there is no indication of the problem happening again but of course cannot guarantee it will not happen again. This is clearly an indication that the problem may not be fixed and noone can tell me whether its safe to drive or not. I'm scared for my own sake and for the sake of my 3 young children. I refuse to drive it for fear another incident may occur.

I own a 2003 hyundai elantra. While stopped at a traffic light with the brakes on the rpms increased and the car surged forward. This has happened about 4 times in the last year. I was able to stop the car by breaking again. The current mileage is approximately 97000. I had a 90000 mile check up and maintenance about 2 months ago. This has occurred once since then. If I was any closer to the car in front than 1 car length I would have hit it. I am getting it checked by the dealer this friday.

Vehicle experienced sudden acceleration after brakes were applied.*mr consumer applied all his weight onto the pedal and it didn't stop until a couple of feet behind the line. He realized the engine was revving up with his foot on the brake and not the gas. His wife suggested he shift to park. When he did, it sounded like the engine was going to fly out. He shifted back to drive, keeping full pressure on the pedal. After the light changed, he carefully released his foot and the engine returned to normal idling. Consumer planned to get it serviced but wanted a record of the failure on file.
