During one incident while pulling the vehicle out of a parking space and barely tapping on the gas pedal in reverse, the vehicle over accelerated almost hitting a pedistrian. The vehicle was taken to the dealers on four seperate occasions and they could not determine the source of the problem. The dealer will no longer provide further assisstance.

Seven instances of unwanted engine acceleration since Jan 2006. All occurrences similar: 1)engine is warm after a period of driving; 2) car decelerating approaching stop sign, traffic light, or in stop-and-go traffic; 3) a barely audible "click" is heard and the engine RPM begins to rev up making braking difficult and giving a clue that something is amiss. When this point is reached key was turned off or idle selected to see how high the RPM would rev; 4800 is the highest noted. This is a random event as the car has over 10000 miles with 7 occurrences. Latest date is noted below.

Car driven for 6 miles. Engine shut off for 1 hour. Restarted car and shifted to dive. Car moved forward without problem. Traveled 3/4 mile and stopped at traffic light behind some cars. Had right foot on brake pedal, car started to move forward, pressed pedal harder but car continued to move forward. Noticed rpms at 4000 without gas pedal being touched. Shifted to neutral, depressed and released gas pedal. Rpms at 3500 and dropped to 1000, rpms jump to 3000 and back to 1000, rpms jump to 2500 and back to 1000, rpms jump to 2000 and back to 1000, rpms jump to 1500 and back to 1000. This process took about 25 seconds. Put car in drive, all seemed ok very bad situation. ***note: Car temp was slightly below normal ****

My 2005 Hyundai XG350 has a very dangerous hesitation problem. This problem is generally encountered form a cold start out of a parking lot or garage. The gas pedal is slowly depressed to accelerate. Sometimes, it responds normally. At other times it just coasts no matter how hard you push on gas pedal. Suddenly it will lurch forward with enormous torque (depending on how the driver responds to the coasting problem). There are two problems with this hesitation: 1) pulling into traffic and than not accelerating can cause accidents 2) more importantly, the unexpected quick acceleration can cause loss of control, hitting something or somebody, or worse. Resolution to this problem is not considered by huyndai at this point. Denial of other cars having similar problems are common at factory level, but are admitted at dealership level. Incident date is first time.

: the contact stated there was a intermittent acceleration problem. While depressing the accelerator pedal, upon initial acceleration, the vehicle hesitated and then suddenly accelerated.

2005 Hyundai xg350L seems as though it is going to stall. ***** the consumer stated at times the vehicle would barely move, it didn't matter how much she attempted to accelerate there would be no response at first and then suddenly the vehicle would surge forward.

I purchased a new 2005 xg350L on December 7, 2005. My initial opinion of the vehicle was that the car ran sluggish unless it was warmed up at least for 5 minutes before driving. Then on December 26, 2005 we went to the store and before turning off the car there was a rough idle. About 45 minutes later we left the store and proceeded home. I sat in the passenger's seat as we drove about of a mile and was forced to sit in stop and go traffic. We stopped with about car length between us and the car in front with his foot on the break. All of a sudden the car started easing forward. He applied more pressure to the break and the car continued to move faster. When he realized the car was not going to stop he then pressed the break with both feet with all of his strength and the car accelerated even more and lunged forward into the car in front pushing it towards the car ahead of it. As he put the shifter into park when the car went into neutral the rpms of the engine revved really high, when passing reverse it made a loud knocking sound making the car shake, and when it reached park the car`S rpms revved very high three times consecutively, faster than physically possible to floor the gas pedal manually. All of this happened in the time it took the driver to take his hand off of the shifter to reach the ignition to turn off the car. Immediately after the police instructed us to move the car into the parking lot I called the dealership to report the problem. The service manager instructed me to have the car towed to his dealership the next morning. They kept the car two days trying to find the problem with no result. The dealer wants to return the car to me since they did not find any indication of a problem. I purchased this vehicle with the expectation that I would have a safe and reliable car for personal and business use. I selected, what I thought, the best among all models. Now I am liable for payments on a car that is unsafe for me to drive.

2005 Hyundai xg 350. When backing out of the garage and stopping to put vehicle into drive and when pressing the gas lightly vehicle accelerated out of control. Consumer had to step on the brakes to stop vehicle, and this situation repeated by itself. Had to take back first car to dealer, an the second car was doing the same thing. Moreover, while driving away from home at 15 mph and approaching an intersection applied the brakes and vehicle attempted to lunge forward, . had to put both feet on the brakes to stop vehicle. Dealer urged consumer to bring vehicle in or have it towed. Dealer offered a loaner car. This was last Friday, and consumer has not heard back from them. Did not know what the problem was.

Contact stated when the vehicle was put into drive and the accelerator pedal was pressed vehicle lurches forward. Sometimes this left rubber marks on the pavement or road. At times when the vehicle was put into reverse it would do this in reverse as well. The vehicle when put into gear will go into the higher gears until the rpms reached 4000. Consumer had logged 600 events, and there have been 54 occasions when this occurred. The service dealer did not know why this happened, but did replace the vehicle with the same make and model of this vehicle, and it did have the same defect. The dealer stated there was no recorded complaints with Hyundai. Consumer has contacted the manufacturer several times, but had no resolution. Consumer no longer had this specific vehicle, but felt this was a safety defect and someone should be made aware of this problem.

Consumer stated when he stepped on the brakes the tachometer climbed. This problem didn't happen all the time, but twice. He almost veered into traffic. The dealership and manufacturer could not duplicate the problem, there was nothing they could do. The last time this occurred, the consumer picked the vehicle up from the dealership, drove home, then went out, and the vehicle revved up to 2400 rpms. He has documentation of these circumstances.
