Are any 2019+ trucks showing up with any recurring issues, or stupid design screw-ups (aka ford spark plugs in the Tritons, Chevy cylinder deactivation failures, etc)?

 

I bought my 2019 Ram in June of 2019. The only issue I have had is replacing both Ext mirros. The plastic parts in them broke. The dealer told me he has had to replace several of them. He thinks they went to a cheaper source and the units are not holding up. The dealer replaced them under warranty and so far the replacements have worked fine.

 

I have a 2019 with a 5.7 and I'm having an issue with the MDS causing a rumbling noise/vibration when I give it gas. Feels like it is having a problem or struggling going from 4 to 8 cylinders. For now, I manually take it out of ECO mode but pressing the minus button on the steering wheel and putting the transmission into 8th gear. The results?
1) runs a lot smoother, although not as good as I would like;
2) with it running on all 8 cylinders all the time I see no loss in gas mileage, so I feel the MDS/ECO stuff is useless;
3) I definitely feel the transmission downshifting when I take my foot off the gas, which helps me use my brakes less, especially where I live where there are a lot of hills.
