I bought my ED in Sept 2019 and justI have a 2160 EcoDiesel and have noticed minute steady loss of coolant over the past year or so. I reported it before I knew of the potential flaw. The dealer couldn't find anything. Interestingly, following the initial recall notification I saw a slightly accelerated loss, and decided to bring it in. The service department said the found a very slow weeping occurring with "3-way valve," which they replaced. Now I'm back to a much slower consumption... very suspicious.
seen these post, I went out and checked my coolant tank and it’s down quite bit. I’ve only put about 3000 miles on it since purchased.
