Well hi there. Looking at some late model- as in 17, 18, 19ish WKlls. I had heard about engine issues with the 3.6s involving overhead failure and some things about cooling systems. I haven't kept up with Grands after the WK so playing some catch up here. What's the word on these 16 and up "updated" versions. Yea/nay, still issues or is it an improvement. As stated I don't even know much about the other issues or the occurrence rate, because I live in a ZJ bubble. Thank you many much
