| Description of the problem | Very dangerous situation: toyota sienna 2005 vsc (anti skid system) kicks in unexpectedly for no reason. Numerous times i have been driving straight along dry roads only to have my abs (antilock braking system) suddenly come on, the van slow down, with the vsc alarm going off, and the vsc light blinking. It's very scary, especially on the highway, and it becomes hard to control the van. This has happened at high (~55 mph) as well as low (~25-30mph) speeds. I drive 90% on smooth, well-paved suburban roads, and about 10% on highways. The frequency of this defect is definitely increasing. One day it happened 4 times in one trip! All for no reason, and all under dry, normal driving conditions on smooth, suburban roads. My van has 113k miles on the odometer. This defect creates a very dangerous situation where the vehicle slows suddenly and unexpectedly, and swerves to one side without warning. I can't understand how there hasn't been a recall yet. A quick search online shows many people have had this exact same experience. |
