Yesterday, my battery light came on twice during the day, but did not stay on. The car seemed to be running normally. This morning, the light never came on. Should I have it checked, or was that just a fluke?
Do I need a new battery? on 2007 Toyota Highlander
Have your charging system checked.
most likely its 6 yrs old but have it tested
The "battery" light refers to the charging system which means the alternator and its circuits. A random charging system light suggests that your alternator isn't always able to provide electrical power to the vehicle while your driving. That's needs to be checked before it leads to a no-start, or causes the car to quit while you are driving.
