There's no cylinder deactivation on the Cummins. On the Hemi, unlike the GM engines, it's now mostly due to not changing oil. I had dozens of Hemi service trucks many with 200k+ and never replaced any lifters. The once excellent GMs were very troublesome when they went to the DFM system.

I also didn't care for its rough ride, numb steering, and the rattling of interior parts. The 5.7 Hemi without the MDS was a fun motor to flog though.

Every make has its faults. Question - if you hate Ford so much why are you here?
Just curious.

Very true. We had a 2010 Yukon that was a great vehicle. We were on a trip, I got the "Engine Oil Low, Add 1 Quart" message. Stopped at a local Walmart and added a quart. Once we got home, I went online and ordered a new ECM that had the 8-to-4 eliminated. Changed that out and it ran great for the next few years without using oil. Even with the new setup, they're still not near as reliable as the older V8s. I still have an original 5.3 in my 1999 and have had many offers for the truck. Many like the fact it has the first series 5.3 engine. Same can be said for the old 302 and 351 in the Fords. They were dang near bulletproof, too.
For anything short of heavy towing I tell people to also look at the much derided 2v modular F150s. They were some lazy SOBs compared to modern VVT motors, but they will run and run and run, slowly but steadily.

To my knowledge the Hemi cylinder deactivation is on two middle cylinders on one bank and both end cylinders on the other bank. Yet on the Dodge and Ram forums there are reported lifter failures on any cylinder not just the MDS ones.

If you take care of it, it'll take care of you. If you don't, well...the old saying goes, 'if you don't schedule maintenance for your equipment, it'll schedule it for you.'

Most of the 5.7 Hemi issues stem from the fact that the oil spec keeps getting thinner and thinner without any changes to the engine. Notice that the 6.4 Hemi engines that spec 40 weight oil have FAR fewer issues.
I dumped the 0W20 out of my last 5.7 Hemi and put 5W30 back in and my valvetrain tapping immediately and permanently disappeared.

People who think that any brand is immune to issues is in for a rude awakening. I've maintained a small fleet of Ford/GM/Dodge/Ram trucks for the past 35 years and I can tell you with certainty that any and all can and will break down and have problems eventually. I buy trucks with the features I like, the ones I get a better deal on and the dealer also plays a part in the decision making process.....I wouldn't buy any of the big three trucks over any other over some perceived superiority in reliability. Certainly there are some known weak links in all vehicles but overall, you may have problems or you may not - often it's luck of the draw. All you can do is maintain them properly and keep your fingers crossed.

I cannot speak for everyone, but I can speak for myself. I am in no way saying any brand is immune from problems, but it isn’t any secret that Ford has been on the struggle bus the last few years. They have lead all auto manufacturers in recalls and warranties the last two or three years. It doesn’t seem like they intend to give that spot up in 2024 either. So in general, some manufacturers are making better products than others.
