Wait until you get the VCS light with the engine light and some other light that comes on at the same time. After much troubleshooting, I found that it was due to my fuel cap not sealing correctly. (Gasket worn). Replaced the cap, disconnected the battery to reset the lights and computer, then had to figure out why my windows no longer worked correctly. That required some youtube help on how to reprogram the window motor sensors. I finally got it done and no more issues. This is my 2nd Highlander and really like it as a commuter vehicle. Good luck on getting yours squared away.
