We replaced 1 quart when the fix came out but still get some popping on nights when there are big temp changes. We have told our service guy about it at our dealership where we have an appt next week. We are doing our almost out of warranty list of things to be checked. Anyway, he said he had never heard of this problem. That does not inspire confidence in him..... There is no way he will hear it since he won't be there when it happens, if it happens, since there needs to be that big temp change.
Should we just replace another quart? Contact Lippert again to make sure our case is in the books with them? Have the service guy check for air in the lines which is what he said these kinds of things are caused buy?
