2010 Toyota Sienna with check engine light, VSC and TRAC Off all on at the same time.

Hi MAGGIE1

Because several systems had a problem all at once I would start by checking the fuses.

Here is a guide so you can get started.

Next scan the computer for codes to see which ones come up.

You may have a problem with the engine management system and other area.

It is ok to drive the vehicle but you might have performance related issues as the engine management system has detected a fault within the system.

As far as expenses we must first determine what the problem is.

Please let us know happens so it will help others.

Best, Ken
