I'm # 100k with this issue yeeeeeah

[HunterCat]

It’s a 22, how do you know you went for better reliability?? I mean you say RAM lies about the 5.7 but then turn around and believe them when they say the 3.6 lasts for ever!!!! Also I’d like to know how many of these “100k” engines followed service recommendations. No one is posting “the rest of the story”! I know there are stories like “I have 250,000 on this or 325,000 on that and no problems but personally I feel even today over 100,000 miles anything can and does happen with all makes and models’, and I doubt if the 5.7 is under warranty that they refuse to repair it.

I guess you're under the impression that the 3.6 was just introduced in 2022. I guess you're not aware that they've made millions of these engines.

I'm not taking RAM's word for anything. The 5.7 is infamous for its fatal flaw. Do a simple search on the internet and it's awash in first hand accounts.

You want to believe that it's all a matter of people not following service recommendations? Have at it. I guess people with other engines are for some reason more diligent about doing service.

I really can't understand the emotional attachment and blind loyalty to the 5.7, or to any tool for that matter. I think most of the HEMI loyalist rent their vehicles or replace them every few years. They have no problem thus the problem does not exist.

So they haven't made millions of hemis?

The internet isn't awash in 3.6 cam failures? Never visit Jeep forums, do you? More hemis are probably *reported* on Ram forums because more people forum goers have hemis. Jeeps, with very limited hemi options, enthusiasts are stuck with the 3.6...and report failures.

I largely agree. The point of addressing misinformation isn't always to change the mind of the person you're addressing on the Internet, but all the others reading it who may otherwise be swayed by the misinformation if left unchallenged.

I only had a 2009 Dodge Ram 1500 SLT 5.7L

I sold it when it had 144,000 miles on it back in late 2016

It only needed exhaust bolts, back around 2011

I had not seen the guy that bought it for at least 4 years

My neighbor told me last week, that he stops by to ask about my health & he hauls stuff to the swap meet every week with it. His father also drives it & waves to my neighbor.

The last time that i talked to him, he had only replaced the water pump.
I should catch him & ask about the truck

I'm definitely willing to keep an open mind. I did some research before I purchased my truck and I was aware that the 3.6 had troubles in the past. I thought that was all sorted out so shame on me. Apparently, RAM can't produce a good engine. There's a class action lawsuit for the 5.7 and 6.4 as well. I guess this is why RAM has been at the very bottom of CR reliability ranking for as long as I can remember.

You have access to fleet data and other inside information? Great, let's see it. Show us how widespread the problem is for both engines and what percentage of motors fail for each.

You're referencing internet posts and youtube videos right after you chastise me for referencing them.

I "referenced" internet posts and youtube videos to show anecdotal evidence exists for the 3.6 just as it does the 5.7, not to show it's a bad engine. Every motor fails, every maker has lemons. You can't claim the 5.7 is bad and the 3.6 is great on anecdotal evidence if it exists on both sides, right?

You must not remember very long. CR currently ranks Ram as average, but I wouldn't trust CR to be honest on automobile ratings, personally.

Already referenced fleet data earlier in the thread as far as I can/will.

"I guess this is why RAM has been at the very bottom of CR reliability ranking for as long as I can remember."

It appears your memory and facts have taken a different path. I'm sure Ram (then Dodge) trucks have hit bottom sometimes in years past, but there's seems to be an obsession with casting Ram trucks in as bad a light as possible. According to CR data since 2014, Ram 1500 reliability has been AVERAGE for 2016 through 2021 model years. (see images) Oddly, in the same reporting period the GM version have been rated "much worse than average," in all years, and the F-150 having a "much worse than average" for '17 & '18, with an average for '19 and really good rating for '20, and "much worse than average" for '21 & '22.

I'll be glad to look at previous years if you so desire.

In the totality of your comments, one has to wonder why you would purchase a product you hold in such mistrust and disregard and done so for such a long period of time.

[Hellcatsrock]

OK, now you guys have me freaked out. I own a 2015 Longhorn 5.7 with the 3.21 rear end, air suspension and 65,000 miles on it. I just picked it up from the dealer repair yesterday for a broken cable to the inside door handle drivers side, and getting a right front wheel bearing replaced on my extended warranty which is expiring in a month. Prior repairs were the electronic control for the power steering, replacement of radio for the screen issue, plugged sunroof drains, cruise control issues, non defrosting rear view mirror and minor trim issues. I'm a gearhead and my other car is a hellcat redeye charger which i drive hard and drag race.
I ran from my 2011 Chevy truck over this same camshaft issue for the safety of my Ram (or so I thought). The chevy issue had been going on for years and continues again now. So I am well versed in it with Chevy having claimed in its recent models failures that the lifters had not been hardened properly. But I believe the common issue is the MDS. I love this truck and would love to keep it but don't want to pay for a new motor down the road. So what is my best option at this time.....put in new camshafts, eliminate the MDS, or have my bearings and pistons already been damaged from the debris coming off the camshafts? I have always changed my own filters and synthetic oil before 5000 miles. Or do I sell it for a high price now with its low milage and exterior/interior looking like new with decent tires and new brakes, and buy a new loaded one and get a lifetime warranty? I have zero interest in the offerings of GM and Ford and hate yodas out of general principal.
Or should I just drive it and eat an engine rebuild further down the line? A new loaded one like mine is now $70,000. Big money with already having one expensive toy.

Every automobile forum on the Internet exists primarily to convince you that whatever you just bought has some fatal flaw. So, if you listen to the web you should definitely sell it. It'll blow up, sleep with your wife, and kick your dog. Maybe not even in that order.

If you do enough research I think you'll find two things with the 5.7 Eagle engine: (1) The actual lifter failures can occur on any cylinder, not just the MDS cylinders. (2) lifter roller lock up incidents appear to have tapered off since they increased the needle bearing size in the roller. These lifters began to be cut-in on engines sometime in 2014. What appears to be the worse year for failures is 2013.

The theories about why this happens is as plentiful as the number of fingers and toes, but none really explain why this problem only occurs with a relatively small percentage of engines, with web estimates of 5-10%. In forums the reports of engines going 200-300K miles without incident are ignored. What I've written so far should tell you where the problem really lies.

Everything wears in an engine. If it's metal and requires lubrication, there is a practical end-of-life to the part. A roller lifter camshaft system offers advantages over flat tappet design, but the small needle bearings are susceptible to failures caused by debris that prevents them from rotating. This is almost always the cause of roller lock-up.

There are a lot of thoughts on oil type, viscosity, and oil change interval to prevent problems, but just in my opinion I think it is far more important to use a reasonable oil change interval and an oil filter that is rated to trap as small micron debris as possible.

Bottom line for you: there's nothing to lose by driving it to failure, if it fails.

It's funny because your dialogue and comments seem eerily familiar as well: "Ford and Chevy produce an inferior product so RAM being better than inferior is a win".

I'm not sure how that point of view makes much sense. How does setting the bar so low incentivize RAM to make improvements? What about comparing the product to Japanese manufacturers? I guess it's a glass half empty or half full point of view.

Look, I don't want to get into an internet ******* match. I just try to call balls and strikes as I see them. Let's agree to disagree. You think the HEMI is a very good engine and I think it's not a very good engine.

As for why I bought my RAM, I was looking for some specifics: RCLB, naturally aspirated, no MDS/AFM, no start/stop and no electronic nannies like emergency braking, lane departure etc. My requirement didn't leave a lot of options available. Overall, I think my RAM is a good truck. I opted for the engine I felt would give me the least grief.

No, what's funny is you stated ""I guess this is why RAM has been at the very bottom of CR reliability ranking for as long as I can remember." and were proven wrong so now you want to move the goal posts. You're obviously entitled to your own opinion, but you aren't entitled to your own facts. CR has *not* rated Ram at the very bottom as you stated so now it's just agree to disagree.

 

[HunterCat]

Sorry, was thinking of JD Power. I don't have a subscription to CR. RAM beat Ford in 2 of the years I was able to find and never ranked higher than Chevy.

 

[El Guapo Phil]

My 2016 Ram 150 4x4 Hemi has been stellar since the day I bought it.
No major problems. I bought the Ram because it was tough. I use it as my driver and work truck. Keeping it maintained is a must for longevity.

 

[Sandevino]

I wonder how many of these issues are truly mechanical failures vs technical misunderstanding or confusion.

 

[NETim]

Sadly, due to the squeeze put on manufacturers by government technocrats/bureaucrats (read: the EPA and other federal agencies), the emphasis is on fuel economy. Durability and reliability are a distant second in engine design.

Then too, the "good stuff" in lube oil is under attack as well for environmental reasons.

If vehicles don't last as long and end up in the scrap heap as a result, are we really saving anything when considering what it takes to build a vehicle in the first place? All the energy needed to acquire the raw materials, processing the raw materials, assembly, transport etc etc. Seems to me that the feds are playing a giant shell game with their environmental policies. Seems like more and more, the goal is to fight "climate change" with disposable vehicles, with the real costs swept under the rug.

But oh boy, it sure does look good.

 

[Jeepwalker]

I wonder how much of the lifter roller bearing issues (when they DO fail) are the result of certain driving conditions/habits as well? For instance, a lot of shorter trips where moisture doesn't get pulled out of an engine as well as longer trips? And there it sits for a weekend like that? IDK ....just wondering. It would tough to isolate...

When in automotive history have motors lasted longer?

Why are there V8s like the LS3 that run essentially forever with the most routine of maintenance?

We continue to live in the golden age of longevity, power, and efficiency...for now. Nostalgia and aesthetic preferences aside, there's no era of better trucks than we're driving today.

I was going to say the same thing that Docwagon1776 stated. Vehicles in general last WAY longer today than 20 - 30 years ago. Take a late 1970's era truck and they were considered just about worn out at 70,000 miles. It was almost surprising to find anything of that era with 100k miles on it......hence the reason most vehicle's only had 5 digit odometers (99,999 miles max) back then. There were vehicles made up into the 1990's that only had 5 digit odometers because you just didn't see vehicles last that long.
I remember as a little kid my grandpa buying a brand new 1979 Chevy K20 4wd truck. It was used around a farm but he literally drove it like a grandpa. Probably never saw over 3,000 RPM or speeds above 50 mph it's entire life. The "legendary" 350 small block started using oil and blowing out smoke at probably 50k, had several clutches put in it. Brakes and tires were probably every 15k, and had most of the body replaced because of rust after maybe 5-6 years, and basically just had to throw the truck away after 7-8 years even keeping up with maintenance and repairs. That was all considered "normal" back then.
