I have a 2011 Edge. Today my brake pedal went to the floor. It stopped the car but scared the bajesus out of me. It's done this before and returned back to normal so I thought it was a fluke. Any ideas what this could be? Car has roughly 160K. Booster? Master Cylinder? ABS?

Thank you both for replying. I'll check both suggestions and get back to you. Thanks again.

Hello, newbie here. I've tried searching in the topics in this forum but not seeing my issues so hoping someone can help. I have a 2011 Edge 3.5. Recently, the fans started staying on, ALL THE TIME when engine is running, even when engine is cold. From some google searches, I've seen comments about the coolant temperature sensor needing to be replaced. Does this sound correct or could it be something else? If so, what? Where is the sensor located?
