Since I bought my 1998 used Toyota Sienna with 190xxx miles, when press a litte bit the gas pedal on a uphill it start to accelerate like crazy, I can barely stop it, I must to put the transmission in neutral to stop the van, today I was on a very pronuntiated uphill and almost crash because it accelerates itself when press a little the gas pedal. I''m scared to use the van again but I don't have other choise and at the same time I'm scared to sell the van to someone else.

The car is shifted from park to drive and it accelerates suddenly without me pressing the accelerator. Pressing the brakes do not stop the car, the only way to stop it is by shifting into park or neutral.

I came home and turned my ignition switch off but my 1998 Toyota van kept running.turning the key on and off did not turn it off. I tried shutting it down with the ignition switch again and again and again. I tried turning it off again while moving the gear selector lever but to no avail. I begin to smell burning rubber. I lifted the hood and realized the engine was being turned over by the starter which was not disengaging and starting to smoke. Then tons of smoke began boiling off the starter. I disconnected the positive battery connection and the engaged starter stopped cranking the engine. Heavy smoke continued boiling from the starter for about a minute longer. I was very glad I was not inside the garage because I think the starter could have started a fire or the smoke would have smothered me.

The contact received a warranty extension for transmission problems. The vehicle was making noise. The transmission had no other noticeable problems at this point. The mechanic, who looked at the vehicle, stated the transmission will have to be replaced soon. The mechanic said it was making noise due to defective differential and the transmission was slipping. The service manager stated that Toyota would provide the part, and the contact would have to pay for the labor. Update 1/4/2006 -
