2003 Mazda MPV Acceleration problems

We drive to lake tahoe in my mpv van with 5 people in it. The van jerked when driving accelerating from 40 to 50 mph. We changed driver on the way, and both driver felled the same thing. It seems a transmission shift shock or shift flare. Then when "google" the problem on internet, I found out that it is a very common problem for mazda mpv 5-speed auto transmission. Many people experienced a sudden failure after a few weeks of the "shift flares". This can be very dangerous. Mazda should offer free repair for...

2003 Mazda mpv began to rapidly accelerate while entering my driveway. Even though applying brakes at full force, my vehicle crashed into my garage door. While trying to put gear shift into neutral, I accidentally shifted into reverse. The vehicle again accelerated, the whole while I had both feet pushing on the brakes as hard as I was able. The minivan then shot out in reverse and hit my neighbors' car parked on the street in front of their house. *Nm

Dt: the contact states on two different occasions his wife was in a parking lot and the vehicle started accelerating, causing an accident both times. The last time car was in drive while she was putting foot on the brake to put it in drive she never touched the accelerator. The same thing had both times. The first time she hit a car and a tree and the second time she hit a tree in the same parking lot. The second accident happened on april 30, 2005. *Ak

1. Use of cruise control on west virigina turnpike with mpv 2. Cruise control fails to maintain set speed. Speed will vary +/- 3 mph. In going up hill cruise control over speeds set speed by 3-4 mph, sometimes accelerating at the increased speed by several seconds. At 70 mph this causes the driver to have to brake to avoid rear ending the car in front even though the car ahead may be 8 or more car lengths away. This is a totally unsafe condition. 3. Dealer would do nothing to repair saying that the speed variation was within mfg. Limits?*Ak

Throttle revved, but vehicle failed to accelerate when the gas pedal was depressed. Prior this to incident transmission abruptly shifted into gear. Dealership refused to repair the problem until the manufacturer decided on a remedy.*Ak

While slowly accelerating, the rpm jumps up about 600-800 rpm and the transmission jumps, somewhat violently, into 3rd gear. It only occurrs from 2nd to 3rd. In does not matter what the weather is or how long the vehicle has been operating. It happens about 70% of the time. We have taken the vehicle in twice and the dealer (sherrits sic.) State they can not duplicate the problem and they have not found any fault codes, therefor, there's nothing they can do. I am to continue to monitor the problem. Our van has 6010 miles on it.*Ak
