Some of those maybe fixed now but it seems very hit and miss from some. From the issues my f inlaw has had on his 16 3.5, i would pass on the EB if it was a long term keeper vehicle. If it's a lease then have fun.
EB 3.5 in the F150 does not have an internal water pump. I do hang out in the F150 forums and yes there have been issues, they should be fixed by now. I believe the timing chain stretch was fixed by 2015 - IIRC it was a combination of phasers and casting debris. Same with the CAC - fixed by 13 and the TSB fixes for most. The rest don't seem to be trends.
