The wife and I were on a trip in MS visiting my mother-in-law whose house had burned down. I am from DE so a LONG drive down. On a late Friday afternoon as I was going to the store with a car full of people, the car started churping and it was the car over-heating. Called the local dealer and they could not see the car until maybe Monday. We were schedule to leave on Sunday. Found a local shop that looked at it and it was the thermostat, so they replaced it.
