Survey- For those with misfire issues

[1JeepFamily]

Noticed pinging coming from my gladiator as well.. I really wonder how many of us gladiator owners have this problem & don’t even know it, I probably would of never have known if I didn’t take my doors off & heard it myself

Do you hear that "pinging" from inside the cabin, or only when you pop the hood? And can you describe the sound a little more?

Why do you still have it? It seems like you’d be better served requesting a new one at this point, no?

Im in the middle of all of that now. FCA said then that my vehicle didn’t qualify for a replacement. LOL

For my gladiator which had the misfire issues, the dealer was awesome and let me switch to another gladiator coming in the next month. Currently driving a ram 1500 loaner.

As i read this thread more and more, I am concerned the next one coming in will have the same problem.

Does anyone have any ideas on whether we can do a poll for all the gladiator owners and see if there is a correlation with build date and factory?

So maybe not this thread, but have one that takes into account people that have gladiators that are not experiencing misfire issues? Hopefully this would give us a better idea of where the problem started.

Welcome to our group of misfires. What is your build date?

I've been here for a while. Not sure of my build date bit even if they "fix" it I'm going back to a jk. I cant own a vehicle that wont throw codes when it's so obvious that it isnt running right.

build date inside the driver door on a label.

I suggest a poll that EVERYONE here please participate in.
Ask in the poll questions such as "does your JT have misfire issues"
And ask people to contribute their build date - EITHER WAY. May help determine if it's random or a pattern.
For example, I have NO codes, no misfires, engine runs smooth (a tad rough at idle with AC on on a very hot day but geesh, it's only a 3.6 pulling that AC compressor at IDLE)

So mine is an Overland, NO misfire, no codes, build the week before November 15,2019.
I picked it up on Nov 15th, it was shipped out the Sunday before, I ordered it October 17th, 2019.

You can learn a whole lot if you plug this into a spreadsheet and chart it. Look for trends, times when these were built and NO one has a misfire, perhaps see the misfire issue growing in numbers as build dates approach a certain point, etc.
Armed with this info - you may have a better "case" if you need to go as far as the lemon law bit.
Go in factually, not in anger with hackles up and fangs showing. Be armed with facts, information and be very matter-of-fact no matter how pissed you are and how many FCA employees you wish to strangle.
Any arbitrator will read you like a book and no matter the laws and rules, they'll pay close attention to you if you go in like a pro. Honest, I've been there. The last administrative law judge I worked with said if every attorney that appeared before him wrote their papers and did the research as I did, he'd be a lot happier and his days would go a lot more smoothly.

Like the steering issue - just because I don't have this issue doesn't mean I won't be willing to follow and add support as possible IF possible.
These are different animals for sure - but I am trained in engines and troubleshooting.
The most common issues with any misfire are:
FUEL - especially with injected engines
Ignition - not happening or too weak to matter (timing - meh, not really a misfire, but a weak fire)
Physical - valving issues, especially with modern "lifters" and oiling methods.
Just like a shot lifter or toasted cam lobe can cause a cylinder to not fire or not fire well in a legacy engine, valve issues can cause misfires today - lifter collapsing, etc. - misfire.
Injector sticking - misfire.

It's been at the dealer any time I've thought to check.

I started a spreadsheet and quit at 30. Since then there have been quite a few more. The latest build date I have seen was 2/2020, only one. Heaviest concentration summer and fall of 2019. I will add to the spread sheet and see if everyone can see it. Also I had one built 8/2019 with the problems and serious engine damage, broken cam. I now have another one w/ build date 3/2020 and so far no problems at 5,000 miles. Love it but don't trust it.

This is exactly why once this is "fixed" or bought back I'm going back to a jk. Mine has a bad misfire on cold start and doesnt throw codes. Dealership ran a monitor on it and had over 30 misfires on cylinder 6 in under 2 minutes. Still no code.

I love mine too but I’m just waiting for #2 to throw the code.

I'd love to throw an old-fashioned scope on such a thing......... you can tell a hell of a lot from a scope watching the plugs fire. You can tell lean, rich, ignition issues, and more.

I grew up using an EPA75 and “sun machine”. They can indeed tell a lot about what’s going on. The problem is that with the current technology of engines and ECMs, everything happens very quickly. So fast you literally can’t see it on a scope. We can also thank the EPA for the fault codes.

With VVT and everything else going on very quickly, it has made things more complicated than the typical owner (like me) can diagnose effectively.

The basics still apply. Yes, there is still compression, cylinder leakage, ignition timing and valve timing. The sad fact is that we as owners don’t have access to most of the specialized diagnostic tools that manufacturers provide to dealers.

But, there is hope. We have warranties and legal options that were nonexistent back in the 70s. Keep detailed records, keep your cool, work with the dealer and hopefully, everything will work out.

I still love my Jeep Gladiator.

I tried to contact the admin and get an excel spreadsheet started. That was a week ago with no response.

The old tools will still work you just need to be aware of the additional controls in the background. I completely believe people may be having mechanical issues, but to boot I have seen some substandard calibrations for timing and airflow. My guess is they leveraged or outsourced this development and now it was a biting them in the ass. Never pays to phone it in, for the product anyways

Should still be able to watch, for example, #6 pattern for differences. The ignition cycle is still going to happen at the exact same rate - 1 spark for every 2 revolutions of the crank and idle speed is pretty much the same as anything from the 60s or 70s so you can watch the spark pattern. The kicker is that there's no "central coil" to collect the signal from like the old days so you can really only check one at a time. You'd have to treat it as a single cylinder engine, one at a time.
I should hook my little scope up to my JT and see if I can figure things out. No misfire, but see if I can pull the signal very easily. Heck, I even scope alternator patterns to help diagnose issues there, too.
(well, until the power supply fried, I'm working on fixing that now along with a bazillion other things)
