9995 ,Your 2018 proves that VM in Cento has NOT improved in QC in 5 Years. ( along with many others) Don't let Fiat tire You OUT, stand Your ground and fight. The 2014-19 engine is now out of Production, You are correct on what are you going to get in that replacement.
I've never heard of engine fatigue issue.
