Loss of acceleration after braking. Vehicle will cease responding to the accelerator pedal after braking, will continue to go slowly (~20 mph) for 3-5 seconds, then accelaration will resume. Happens at any time in any situation; brakes just have to be tapped to lose acceleration, has been happening since vehicle new.
My 2004 Toyota Sienna has problems with the vsc taking over the vehicle at different times and there is no problem. It slows you down fast and you have no control. Bells ring and lights flash, then it will finally go off. It is very dangerous. I have read forums of other people having the same problem. Some say Toyota fixed it for free. Others say dealers want over $800. To fix it. Some say it is a sensor issue. Others say a new sensor did not fix the problem. Others say if the tire sensors are not zeroed out after new tires are installed or if you have to change a tire or get them rotated this could be the problem. It is a very dangerous issue and Toyota is aware of this but will not do a recall. Someone is going to get killed or maimed if they have not already. Toyota needs to recall and fix these problems and not have dangerous vans on the road. They need to check the vans for each problem because many people have this problem and while linked to the vsc ,the problems are not always exactly the same. Some have more dangerous problems and more frequent problems. Thank you.

I parked my car on an upward inclining driveway and left it in idle. I went inside the house to go and get my dog and speak to my in-laws. I brought the kennel out to the car, lifted the tailgate and put the kennel in. I went back in the house, got the dog food, put the dog food in the tailgate. I went back inside and was speaking to my in-laws when all of a sudden we heard a loud crash. We went outside and my car had accelerated and crashed into their garage. There was no one in the car at the time of the acceleration. The dog was still in the house with us. The car was in park. The tailgate will not lift unless the car is in park while idling. When the car is in drive, the doors lock. So, we know it was in park. The car caused extensive damage to the garage from the force of the acceleration. The car also had gravity working against it, as it was at an upward incline.
