| Description of the problem | We will be going anywhere from 35 to 55 miles and our vsc light comes on and the van slows, other times the speed will slow it self and than will speed up on it's own. When that (vsc) light and sound comes on the van will also skid. There must be something wrong with vsc system. This van is still in very good condition, we sure swish someone could tell us what the problem is this seems to be a very serious matter. Reading all the other complaints this is not random and toyota should give this matter serious consideration. |
