I own a 2006 Toyota Sienna le with only 26500 miles on it. I was driving my car on the highway doing 45 miles per hour on a dry pavement on Tuesday 09/03/2019 around 6:40 pm and at a sudden moment the vsc light started flashing, warning sound came on, the car applied the brakes on its own hard until it fully stopped, and the engine shut off by itself, which almost got me into an accident. I contacted Toyota and they told me that I have to pay for the dealer to get the car diagnosed for this safety issue, they transferred me to hudson Toyota and they confirmed that I have to pay for it despite that I had my car to the dealer recently for two recalls and they checked the car and gave me a report that everything in the car was good. I have looked online and I found a lot of Toyota Sienna owners from this model complaining about it and youtube videos documenting it, this link shows a Toyota Sienna owner documenting on video the same problem (https://youtu. Be/sy9a8shj0xg) which happened with him 20 times in the course of 90 minuets and the dealer could not find what was wrong with his car. This issue should be fixed under a recall by Toyota because the car should not be able to apply the brake on its own randomly on the highway.
