Car Accelerates On Its Own problems of the 2006 Mercury Mariner

When the temperature is cold, the accelerator will not allow itself to be depressed after 1-2 minutes of driving, and then for the next 10-15 minutes. Occasionally, tapping on the pedal, or pushing extremely hard will make it move and the vehicle will dangerously and rapidly accelerate due to the excessive force required until the driver is able to adjust the force, which sometimes causes the pedal to become stuck closed again on a high speed road. Over the years, this problem has become progressively worse. It is very dangerous and should be fixed by the manufacturer.

I purchased my Mercury Mariner 2006 in 2005. While under warranty, I brought in the vehicle several times to the dealership for service due to the gas pedal sticking. I would try to accelerate and it would stick and not accelerate. After several visits they determined it was a fluid problem or it needed to be cleaned. The problem still persisted after maintenance was performed. At my last visit, the part was replaced. The pedal still sticks, but I am now out of warranty and cannot afford to play guessing games with my dealership at costs to me. On a couple of occasions the vehicle did accelerate rapidly without cause, however my main problem has been the gas pedal sticking. It typically happens during cold humid climate.
