Two problems related to equipment have been reported for the 1998 Toyota Sienna. The most recently reported issues are listed below.
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.
