let me break it down for you
i've seen more ecoboost total engine failures on this forum than 5.0's .. the difference is the 5.0 owners couldn't care less and don't feel the need to post it in every thread

The guys with the 5.0 Mustangs appear to be equally unhappy with their engines...2018+ years.
The 2018 5.0 is different from previous years. It took 3 1/2 years for my 3.5 eco to really start giving me problems which were directly related to the timing chain rattle...and those issues continued to return year after year.
This new 5.0 has been out for 1 1/2 year tops? I guess we'll see.

you seem to have a knack for reading what you want to read.. i didn't mention mustangs to say they didn't have problems.. i mentioned it to say if there are so many high powered mustangs and F150's and the engine is so called unreliable why haven't most of these engines with double the power failed in high numbers. Stu i'm really really starting to understand why rattles and small F150 quirks make you hate your truck so much
In spite of the mis aligned doors, trans shifting and whining sounds, engine knocking, a few other odds and ends, the only thing I've complained about is the engine rattle.

you took a snippet of my post and either took it out of context or had an agenda .. my statement had NOTHING to do with you
let me break it down for you
5.0 Owners couldn't care less to post about the ecoboost engine failures, i've seen more ecoboost owners posting that the 5.0 has problems and the 5.0 should be avoided but based on threads on this forum there is more data and evidence that shows more ecoboost failures. If 5.0 Owners cared as much as ecoboost owners to let everyone know why they should not buy a 3.5 and buy a 5.0 they would post the data.. at the end of the day we don't care to be petty about which engine is more reliable

To be fair I believe there are many more 2.7 and 3.5 eco's out there then 5.0 so perhaps that has an impact why there might be more ecoboost post issues? I also had a very very small chain noise on my 2017 which I could hear only at start up with the window done. lol. I switched from 5W-30W to 10W-30W and the slight noise disappeared. I know the spec calls for the 5-30 oil but I'm not worried about the difference to be honest. Not saying it's going to solve anyone else's noise issue but so far after several thousand miles it's eliminated my start up rattle noise.

Well I'm not going to apologize for having high standards and expectations. I have a fully equipped 2018 Lariat, they don't come cheap.

I had a 2012 eco and never had a single issue during the 5 years I owned it. Did lots of heavy towing with zero problems encountered. That however is purely anecdotal information and means virtually nothing on how reliable is the 3.5 Gen I. It simply means my experience was good and nothing more. I simply DEMAND that Ford stands behind what they sell and never attempt to weasel out of problem they know exists. If something is not right then either recall or at least issue TSB's for known issues. What gets me extremely upset is when dealers know of specfic problems yet still attempt to stiff arm or double speak customers presenting legitimate issues.
Ford needs to step the plate when there are legitimate issues and not have their dealers running interference for them!

when is oil consumption and rattles deem an engine unreliable? i also swore i saw John post his 3.5 had a rattle as well .. FYI my 5.0 doesn't have oil consumption issues and a little off the throttle rattle isn't what i would consider unreliable .. i've seen more ecoboost total engine failures on this forum than 5.0's .. the difference is the 5.0 owners couldn't care less and don't feel the need to post it in every thread
