Hemi 5.7
I have been looking for a newer truck (4th gen). I currently drive an 03 hemi and want another hemi. However I have read an alarming number of posts about lifter and cam shaft failures on the mds motors. Just how prolific is this problem? My third gen hemi has ticked for the 93k miles I have owned it and it has never failed but from what I've read the tick on the mds motors likely means lifter failure.

The issue is you only hear posts about lifter failures because people only post things about lifter failures. No one wakes up in the morning and starts a post about how their truck doesnt have lifter failure. If you think about how many rams leave the assy line and compare that number to cam/lifter failures, it's a fraction smaller than anything. Yes it does happen but the likelihood of it occurring to your truck is minimal. I have an 07 with mds it has 138k miles and it goes in and out of 4 cylinders like it did when it was new and I have never had a failure. They're great engines. If you can buy one with about 60-70k miles and it doesnt tick, it most likely wont. The tick usually starts when it's relatively new

I would guess that for every one that had a failure there are maybe a thousand or more that have been doing fine for well over 100k miles, as the above poster said the thousands of trouble free hemi owners out there never post about having a trouble free engine.
my 2011 ford fusion, one could have months of reading on transmission problems but mine has been fine fore over 100k.

once again, where do hear this from? take a look and the total amount of 5.7s made, what do think the % is of failed lifter and cams. do you really know the driving habits of those people that did fail. was there proper maintenance done? theres alot of factors here. guarantee if you goto a ford or GM forum you're going to hear the same thing.

On the forum, nothing but failures seem like. In the last two years, if i talk to someone with a 4th gen, ( many many) People, "Like your truck, any issures" ( I intentionally do not mention lifters),Never not once did i hear engine trouble. Not many had any issues. Sleep well my friends.

I've been so many places with my truck. Where I live Rams are simply the truck of choice. You see ford and gm trucks but Rams are everywhere and I'm ok with that. I've spoken with so many people and only one had an issue with a misfire in cyl 5 leading to a new engine. He had a 2012 hemi. That's it

From what i'm seeing, not that there isn't a variable to consider with newer vehicles not having the issue yet, is that the lifter issue rally peaked out in 2011, dropping before and after that, most recent failure at all i believe was a 15 but only one that year iv'e seen, closer to 11 more ive seen. So there not totally immune yet. But probably rare.

It takes me forever to find a newer vehicle. Every one I have owned I have been plagued by paranoia about there being a fatal flaw with the motor. When I bought my 3rd gen I scoured the internet for posts about the valve springs breaking on the early hemis and dropping the valve into the cylinder which mine has never done for the 5 years I have owned it. I'm just trying to get a feel for the risk or which particular years seemed to have a higher failure rate. It seems like 2011 was the worst year for some reason. I used to work in a repair shop so I am pretty mechanically inclined and can find problems on used vehicles, I'm just worried about something developing after I put 20k miles on it.

I have come to realize, ( very paranoid as are you ) that the more research you do the more "bugs" you will find. I once researched manual tranny oil on the Subaru Forester forum for so long until i decided whatever is in my 100,000 mile tranny now, will just be fine forever.

Few topics i tend to avoid: oil filter, mpg, trans oil, mds. Now i say that with a little humor, i do of course look into those sometimes, but what i mean is you will run yourself into the ground to make a decision sometimes. So much back and forth, thats BS, no way i will get that mileage, used that super duper top teir oil, my motor blew up the next day, kind of talk.

In the end, make the best decision you can with some research and in the end it boils down to the odds of it happening to you. All vehicle manufacturers have turds, some more than others. One big one with engine oil i don't go by is the Oil change monitor, i like to change between 5 and 7K miles, Not saying there isnt oils that can't go that long, i just accept the money it costs to do it earlier. Why go up right to the line of when the oil loses its protection, just cut it a little sooner and i don't have to worry as much.

Like others have said, i see more easily as many rams in my town now than anything else. Which is a lot more than i used to, there climbing the ladder in popularity for a reason, if there were that many failures, you would probably hear a lot more about it than you do.

Thing about it is, by the time we realize how amazing some vehicles are, ( how long they last almost problem free) its too late, they all have a ton of miles on them.

If we knew how good the mid 80s Toyota 4x4 were most of us would have bought one of those,like them or not i would have. Or many years of the Chevys 90s to the 20010 or so, almost indestructible.

So, i've trained myself, not to stress so much, do the research you can, talk to others on here and i'm sure you will make a decision your eventually happy with.

PS, the Ram was the first vehicle i've ever bought purely on impulse, I did, NO research on it.

The best V-8 motor I thought I had owned previously was the Chevy 5.7 350 vortec in my 98 suburban. Smooth, easy to work on, reliable, and lasted well over 200k (still going after I sold it to my brother in law). The V8 Hemi is better in my opinion. Great horsepower and torque, smooth, great power curve, really good mileage/fuel efficiency for a big motor and when paired with the ZF8 tranny I really don't think there's a better combo especially since you can add 100 HP and still have a reliable engine. Yes, it has an Achilles heel with the single cam and relatively older pushrod design but man, it really is a great motor. If you get too worried about the cam/lifters, it's actually a VERY easy motor to work on also and over a weekend you can put in higher quality parts to make it more reliable. I have a ton of friends who have dealt with crappy Chevy/GM and Ford motors with (subjective opinion here) more key problems than the hemis. On the downside the Hemi is more expensive to buy parts for due to quantities, but heck, I still love the motor.

X2. The 5.7 Hemi and ZF8 are the best combo going in my opinion. Only complaint which isn't a complaint so much as a wish it had a sport mode. Guess I'll wait for warranty to expire and get the PC.

Would they be able to tell if you installed one and took it off for work, wouldn't think it would leave a footprint.

I still own an 03 QC Hemi Sport. I bought it brand new. Never had any major engine problems but I only have 54k miles on it. I was getting only 11 mpg and lack luster performance considering its a V8. As you know, it has a 5 speed trans. Wanted to buy a new truck but dam they are so expensive now. So I bought a used 2015 CC Sport last year. Wow, night and day difference. Way better performance with the 8 speed and better mpg with MDS. This one had the tick. Dealer repaired broken exhaust bolts on both sides at two different times. So far, running smooth now with Redline 5w30. It has 49k miles now.

OP, if you can find one that you like, go for it but I was very picky. Took me 6 months to get mines. Tried to buy a 2/3 year old F-150 STX, couldn’t do it. Rams got the best interiors.
