Misfiring after 475 miles

[frogjbm]

I cannot seem to find it now. But someone posted there is a wiring harness on the back of the motor that can be installed incorrectly and wear through and cause it to short. ?

Yea to me this seems more plausible, because it’s only effecting a small percentage of RHO’s, whereas software would effect everyone.

Sounds like something the manufacturer would/should push out to delivery dealers to correct during PDI.

Ya I remember that from a long time ago, would be great to figure that out so we can check it when our trucks show up

Exactly

Generally speaking, I would agree with you. However, there’s always the chance that software or firmware could affect trucks differently. This has certainly been the case in the past few years with Uconnect5 updates. Some trucks had massive problems with a certain version, others didn’t. I remember reading that the difference might have been due to minor nuances between different suppliers of the same part.
Not suggesting that the misfires have anything to do with this, though. I tend to agree that there’s a physical problem (like a melted wiring harness).

My wife had 2010 Honda Crosstour. Started missing and going through plugs. At 56K they replaced the engine. It was a mass recall for a bad wiring harness.

Yea that makes sense, but at this point one would think a sw issue would have been identified already. This will get figured out, but holy cow what a major cluster fuck this has been for people.

@Raddonkey posted this... There is an engineering case for the wire harness creating theses misfires. The injector command from the pcm is on the ground side. SO if this is the case if the injector harness shorted t ground it would explain the injector wide open and creating this hydrolock concern and the melted cats that others have seen. I sure hope that dealer just rolls you out of the truck or Stellantis makes it right with a buy back/replacement or expedites the engine and repair. The wire repair has been successful on several misfire concerns I have seen. I cant say for sure in your case, but most likely the culprit.

Send me a PM if I can help in anyway.

I don’t think I’d want a repair. I’d want new.

How close are you to lemon law and the vehicle being down more than “X” amount of days for your state?

Not sure if your are asking me but in AZ from what I’ve read it’s 3-4 times in for same concern without being fixed or 30 days out of service mines now been there for 30 days without repair and one of the cats now went from an eta of today 1/6 to no eta so who knows how long… but it’s ordered as VOR which is highest priority a dealer can order. We have reached out to lemon law lawyer. This afternoon my husband got a call from the case manager saying they denied the buy back.

Well….RAM just fucked up didn’t they?!

That is NOT going to be a very good look for Ram or your dealer. Please be sure to spread your case information online both far and wide - maybe one or both will reconsider.

I actually pulled this up while I was there. The tech said that wouldn’t impact the injectors the way that the current issues are happening ie each off by exact certain % in matching cylinders but rather impact all cylinders with random / severe outputs and would be inoperable vs mine that was driving “normal”. Just his thoughts.

As a reference point. 90+% of RHOs sold at my dealer are already back in the shop… I think this misfire issue is systemic and will depend on how/what/timing of drive modes used etc. Or it’s that the cats were manufactured defective. That will be ruled of when mine are replaced and if it does or does not resolve.

He did see the melted cat issued on the grand wagoner but there has not been a solution or cause found atm..

90+% back in shop for misfires??? Holy Shit!!!

Seems excessive.. that's quite an anecdote.

 

[RamFan]

To expound. The vehicles back in are not all for the same reason. Some are electric/ sensor issues some are active misfires but no melted cats. Mine is the only one with melted cats. Again just data point and a lot of ways to cut it. My original order just arrived so obviously hoping for the best..

How many trucks have they sold?

Chris

And up to 475 miles you had zero issues?

I wonder if taking delivery in a different state with different lemon law rules is a factor?

If this were true, it wouldn't be unique to any specific dealer and RAM would have suspended shipping any more trucks.

I'd agree

Every state has different lemon laws, unfortunately it will probably take a letter to the legal department as I don't think the case manager has any authority to approve a buy back.
