2007 Hyundai Tucson with only 22,000 miles on it is now experiencing sudden unintended acceleration. Hyundai is in total denial and squirted some lubricant on a linkage and sent me on my way. After not being able to drive this vehicle due to safety concerns I demanded that the same tech come out and drive it for his self. After getting on an interstate the same issue happened to the tech and now they are stating that something is wrong just not saying what. Sporadic sudden acceleration is experienced with no warning. The gas pedal will actually fall rite from under your foot or more precisely is sucked out from under your foot. The engine tacks out at top end and if driven for a while this will slow down to normal driving conditions.braking is impeded by some mechanism and does not stop the car and after standing literally on the break pedal I was forced to shut the car down and coast wildly into a break down lane. This issue has been experienced now for 3 months.car has been to the dealership 3 times now for this issue. The described set of occurrences above have taken place a number of times and with varying degrees of severity. When will these car companies get the message" how many people need to be killed by these kinds of engineering flaws before real action is taken"

The contact owns a 2007 Hyundai Tucson. The contact stated while sitting idle at a traffic stop, there was an abnormal increase in engine rpms and the vehicle suddenly accelerated without warrant. The vehicle crashed into a preceding vehicle. The contact confirmed this was the third crash resulting from unintended acceleration in the vehicle. The contact confirmed that when the acceleration would occur, the vehicle could be stopped by switching the gear to neutral. The vehicle was left with the dealer however, the dealer was unable to duplicate the failure. The failure mileage was 50 and the current mileage was 28000.
