I am wondering if any commenters have had issue with radiator shutters not closing in cold weather? I just had the re-call done at the end of Nov. on my 2018 CRV. I am still unsatisfied with the cabin heat and continued rise in oil level. However I noticed today that the bottom 2 shutters close but the rest remain open leaving the rad exposed. The weather is pretty cold. You would expect that all the shutters would be closed at least until the engine warmed a bit. Prior to the re-call I thought that the shutters were all closing normally. Has anyone had any similar experience or thoughts?
