Car Accelerates On Its Own problems of the 2005 Mazda Tribute

I have been experiencing problems with my 2005 Mazda Tribute. The accelerator will be depressed and the car doesn't move. Then it will suddenly lunge forward. Other times, I press the accelerator and there is a jerk as the car once again lunges forward. Yesterday while on the highway, the car suddenly accelerated momentarily. This problem has been listed on the internet many times but it seems that someone will have to have an accident or die before there is a recall. It doesn't appear to be a new problem as they recalled earlier models than 2005 for what looks like the same problem. This happens intermittently and sometimes there are days between episodes. Up until this occurrence, the Tribute has been a wonderful car. This, however, brings memories of Toyota. Please investigate before someone gets injured or killed.
