I had a 2015 1500 5.7 and they had to work on my Hemi and the exhaust manifold problems Two times. The first was just the bolts. The second still under warranty was the more extensive fix. I believe they may have put the "better" manifold similar to a ProMax fix. No problems for the next 30K miles till I traded it at 70K. My dealership had a dedicated tech fixing the 5.7 Hemis. That was 80% of his job. He said he took his and bought the after market exhaust manifolds of some sort and also mentioned titanium bolts of some sort? He said he did it proactively when he got his, but it likely was easy and no labor.Out of the 5 Rams Ive owned over the years 4 of them ( all Hemis) had the issue where the exhaust manifolds warp and break the studs. I got the kit from ProMax for removing the broken studs and never had one I could not get out. The kit is pricey but well worth it. On my last Ram ( traded for the Gladiator) I replaced the OEM manifolds with headers. That was a mistake because 6 months later the headers cracked. I took the warped OEM manifolds down to a machine shop and had them sanded down level again and bolted those back up. I got real tired of working on my truck and its cramped and hard to do when dealing with the manifolds. Everyone says they will warp again but Ive traded my Ram before that will happen. Ive had my fill with the Hemi manifold issue! If you decide to do the work on your Commander checkout https://promaxxtool.com/ Ill bet you the same kit for the Ram would do the Commander. The tool is top notch! I know the Pentistar may have its issues but im so glad to get out of a Hemi. Lastly BD Diesel makes an upgraded OEM Hemi Manifold that is not supposed to warp. https://us.bddiesel.com
They could easily do a Promax type fix at production. I'm pretty sure they actuarily figured out it wasn't worth it and damn the customers. I wouldn't expect a change if they start putting them back in Rams or now in Jeeps.
Remember the 100K mile power train warranty on the Rams that was reduced to 60? 70K there around 2016? That tech told me it was because of the Hemi problems and the costs. That was another example of not taking care of the customer. So, some of it rumor but it all rang true. I still had three Hemi 5.7's. I presently have a 6.4 in my 2500.
