Customer Question

I have a 2013 Highlander Limited. It intermittently gets a warning light and the GPS map screen dims to a point where I can't see the map. Other times it is fine. Any ideas about how to correct this? Thank you.

If the display is dimming then I suspect the warning light you're seeing may be the battery light and is coming on because of low charging voltage. A bad alternator would be the most likely cause for low charging voltage.

Can you describe the warning light?
