Had the same issue ,, would go on long drives the car ran cool . Every time i'd shut the car off the coolant in the expansion tank was like boiling water .. No errors no warnings It was driving me nuts, I couldnt under stand why the car wasn,t over heating . Was leaning toward a bad temp sensor .. After a week or so of this , I figured it out . It was the expansion tank cap . it wasn"t holding pressure , it was hissing after 10-15 minutes loosing pressure after I shut the car down . After a new cap ,, all is good , no more boiling coolant .
