How long before the E-torque takes a dump

[Kickboxer]

What is the experience before the problems happen.
I am hesitant about what trouble is ahead.

Like any other system, some will see failures well before 100k but the majority of people won’t see failures while they own the truck since most people don’t keep a vehicle much more than 5 years if that long.

Some of us with pre-Etorque are keeping our trucks far longer than 5 years.

Same for some of us with etorque era non-etorque.

I too was worried about the etorque (I had to buy during COVID and had to take what I could find). I'm at 4 years and 37,000 miles and the etorque has had no issues. Ram got that thing right. Many of the simple things on my truck have had problems, but the etorque has been flawless.

I have no idea how the etorque will perform in the long term, but as many will point out, there's an eight year warranty on that system. I've had the rear window leak, a computer issue that caused the truck to shut off randomly while driving, the brakes moan like a sasquatch in heat when in reverse under certain conditions, I have a vibration in the front end when turning right, lots of other issues, but to date, my etorque has been trouble free.

Have had mine sense 2019. Have 84k on the clock now. Only re-occurring issue is the hood closed switch failing. Had a leak on the third brake light, fixed that myself then there was a recall on it. Had the recall on the ABS system done. My truck has been GREAT so far. I take great care of it!!! Tow a 28-foot camper all over with no problems also.

5.5 years, 127K miles, zero issues.

For a couple years we had two Ram 1500 Limited’s. Mine was a 2021 with etorque and the wife’s is a 2020 non-etorque. In 2023 we realized we didn’t need two top trim level trucks so we decided to get rid of one of them. We kept the 2020 specifically because it doesn’t have etorque. I wasn’t as concerned about the reliability of the system as I was about the lack of replacement parts if something on that system does fail. I’ve read lots of posts in this and other Ram forums of people waiting for months for a 48v battery module or etorque starter/generator.

I am one of the Ram owners that have the 5.7 e-torque and the MGU has failed (starter generator) alternator with no replacement in stock and no remedy either I have called Ram customer support but so far no help

Does that mean your truck will not run?

Good question!!! I too have E-Torque, and have had concerns.

 

[mikeru]

Yes, that's correct. The MGU charges the 48v battery module, which in turn charges the main 12v battery. If the MGU fails you're dead in the water.

Seems like the Etorque failures should be a forum Poll. I've seen numerous polls on the Hemi tick and Exhaust manifold bolt failure, but never an Etorque failure poll.

My impression is that the Hemi manifold/tick failure rates are higher than the Etorque failure rate. Unfortunately, Etorque controller failures are EXTREMELY painful due to parts availability.

I've seen multiple reports of repeat Hemi cam failures and manifold failures. Not sure about the Etorque.

Is the Etorque getting a bad rap because of supply chain problems? Not sure.

I'd start the thread myself, but I don't personally have a horse in the race (seems a bit disingenuous). I do have numerous friends and family members that have experienced Hemi cam/manifold issues. 0 issues with the Etorque (Hemi or V6).

Anyone game for starting a poll?

Considering that the 3rd gen Hemi's have been out for 10 years longer than etorque, which isn't even on all Hemi's from 2019 thru 2022, it's a no brainer that there have been more cam/lifter failures. I suspect you're right about the issues with etorque being more painful because of supply issues. But cams and lifters are essential to the Hemi engine while etorque is not. And having your truck down because of a non-essential system would also be painful. Also, remember that the v6 pentastar also has etorque, although it uses a different MGU. It seems that the majority of post I've seen with etorque issues have the Hemi version.

I get that the Non-etorque Hemi has FAR more units in the the field that the Etorque. I have a 2006 300C with 150k+ on the clock and never a problem with the engine.

I was asking about the failure rate. From what I've seen, the Hemi Tick (cam/lifter issues) affect ~5% of vehicles. Not a high percentage, but painful.

The Etorque failures seem of be at a lower rate (3% SWAG) but are extremely painful due to parts availability. As you said, the fact that it's a EPA add on makes things worse.

Unfortunately, it looks like the go-forward 1500 will be a Etorque Hemi or a Hurricane. I've seen a lot of people voting NO on both. I'm not sure. The Hurricane appears to be doing better than predicted and the Etorque may be getting a bad name due to supply issues.

Your idea of an E-Torque poll sounds fascinating, but it would have zero impact on my level of disinterest.

I suspect you would discover a remarkable difference of opinions on E-Torque among anyone having worked in any sort of technical capacity versus others.

I'm technologically dazzled by the engineering used in these trucks, but also have enough technical expertise in various areas of electronics to understand the concept of variables and the impact to average failure rates.

In simple terms, technology can be nearly endless and accomplish many tasks, but eventually, you reach a level of complexity where the huge amount of variables required to accomplish the process start to significantly impact the mean time to failure.

Also, most Hemi issues can be resolved with aftermarket or readily available OE parts without reliance on a proprietary MGU, or magic giant unit.

Nobody makes an aftermarket MGU.

I don't disagree with you that the actual number of failures is statistically small. But the idea of having this unnecessary tech that can affect the ability to drive my vehicle didn't sit well with me when I had an etorque equipped Ram 1500. When it's working it's not really something you even notice, especially if you install a device to permanently disable start/stop. But you'll certainly notice it if something does go wrong with it.

The difference in fuel economy this system makes is pretty insignificant based on my own testing when I owned one. Maybe in their testing they were able to eek out a mpg difference to pad their CAFE numbers. But in the real world I didn't see any difference. The 2021 Limited w/etorque I owned averaged 15.5 mpg for the two years I owned it. The 2020 Limited non-etorque we currently own has averaged the same 15.5 mpg for the last five years. That tells me all I need to know about how useless this system is. And I want nothing to do with it. For these reasons, neither of the Hemi equipped vehicles we currently own (2020 Ram 1500 and 2024 Jeep Grand Cherokee) has this unnecessary system.

Yes, that's correct. The MGU charges the 48v battery module, which in turn charges the main 12v battery. If the MGU fails you're dead in the water.

Do you have any insight as to what is failing in the MGU from the dealer? Windings? Circuit boards? Heat? Bearings? Housing?

I’ve always had questions about any mileage improvement from e-torque. If there are any improvements it would almost have to be limited to in-town driving with the stop/start and off the line MGU torque boost. But I don’t see how all this hardware could provide any additional economy cruising at 70 mph down the interstate running in 8th gear. As far as I know the MDS is not dependent on e-torque since it’s been on the Hemi for many years - right?

Great info there. I completely agree with every word you said.

Thanks for posting the comparison mileage numbers. I've heard some folks say they get better mileage with eTorque, but how in the Hell would they ever know unless they had some way to actually test & compare, like you did??

One member in here had taken apart, replaced the main bearing and put back together, not remember who tho.

MDS separate. E-torque just that small assist when rolling, you would have to go back and find the video's from FCA on the actual operation. Because if I try to explain, I am gonna get something wrong than beat up. BOIRD beat up enuf these days.

EXACTLY why I will keep my 2019 VVT no e Junkola, who needs all that added electronics and complex ability and 48V battery systems, and step down wiring-charging electronics, these rolling PC's are bad enough without adding that stuff.

NOW they have totally changed the electrical architecture for 2025. Oh baby, am I staying pat. BOIRD skeered, lol.

ALL above IMHO only.
