Deciding to give up on Jeep

[ChrisNLA]

Anyone trying to compare Toyota reliability versus Jeep is delusional.
Any modern Jeep versus any Toyota of any year.
And well, bye. Jeep drivers and Harley clowns. One in the same.

Enjoy the new whip.

If it's spark plugs causing the misfires, warranty doesn't cover it; they're wear & tear items. Coil packs are covered.

Since you have to remove the coil packs to put new plugs in, 2 birds, one stone. However, yes, you don't know which one solved the problem (if it gets solved).

What I suggested you do with your JT - go drive it and get it to go above 5,000 RPMs and see if it induces misfires - is the diagnostic that is the most important one for this f**king engine.

If the misfires start tallying up in the hundreds, it means your valvetrain is taking a s**t and since you have a warranty, Jeep will take care of it. Then you can take it the dealership with an explicit scenario to replicate.

I can go drive around right now with my JT for a couple hours and I'll have a couple dozen misfires. This is SOP in modern engines. This is known. You can search Ford forums, Volkswagen forums, Hyundai forums, etc. You find the same complaints about misfires and people freaking out over them because they have a device that counts every misfire.

Jeep already issued a TSB on earlier JTs because of an incorrect misfire logic calculation would trigger the CEL. Jeep knows and acknowledges misfires occur in the engines. The TSB fix was to raise the threshold before the light was triggered. They didn't eliminate misfires because it's f**king impossible to do in today's engines.

THIS! EVERY ICE engine that uses EFI for a reason: to watch for misfire events and pull timing thus reducing power. Those same systems can tell you what issues you may have, but you have to be willing to test them and do some work (I hate this "consumer" mindset people have).

Congrats on the new Taco! Enjoy the annoying autobraking you can't fully turn off lol.

Now to add fuel to the fire...

I've owned old (90s) and newer (early 2000s) Toyota products, and worked as a master tech for Toyota. I left the service side for many reason: shitty quality on MY2015+, warranty claims being denied when they shouldn't (sound like FCA? well Toyota does this too).

I've always wanted a YJ wrangler, but knew how many issues they usually have when they became affordable to a young adult, and they were usually beaten on where I grew up. But THAT was the era YOU are referring to when Toyota was reliable. THAT was 20 years ago. The new 3.4TT and 2.4T engines are designed to pass emissions, and emissions RARELY allows engines to be reliable (learn the engineering behind it and you'll agree) BY DESIGN. Actually they run them on the ragged edge just to pass emissions.

And I fixed your last statement. I've met Jeep owners that can at least admit they know it's got some drawbacks and quirks...Ford owners on the other hand are consistently more ignorant, reckless, and hot headed than Jeep owners and swear their trucks are "ThE bEsT!" yet need a diesel just to pull slightly more than a 5.7 Tundra (14k vs 10.5k tow capacity).

Also you're comparing brands that only care about their bottom dollar and to this day rely on their PAST reputation to get TODAYS sales. HD hasn't changed their base tech since the 80s, and just like Jeep (Stellantis) they pay other people to design their engines and products when they DO have changes (Porche designed engines, Zongshen for their Asian market, and Kymco for their EV "Livewire"...which they sold off all the rights/etc to ANOTHER company because "it didn't align with our beliefs and values". This is coming from someone (me) who worked for HD more than once in multiple states.

Sounds like the OP has bigger issues than which vehicle is more reliable. They'll probably join the Taco forums and see how many others are complaining about their new truck there too. Not our problem, the people here have made plenty of helpful suggestions and the OP didn't care to listen/try. You can lead a horse to water, but you can't make it drink.

Good morning all! I am on the fence about giving up and selling my Gladiator.
66k miles and I've had the 'misfire' issue for months now. Four trips to the dealership. Did the reflash, serviced the transmission, transfer case, and axles.
The attached photos are where we ended up. None of my trips are over an hour long. The mechanic lied about these long trips and different surfaces. This 'misfire' issue makes no sense to a former merchant marine chief engineer. That would be me.....
The first fault almost got me killed as the Jeep wouldn't take any throttle input crossing a highway. I almost got t-boned.
Is she worth keeping? Or should I do what I had to do with my 2013 Wrangler Sport and sell it? That 3.6 needed a whole new cylinder head at 13k miles. My dealership has gone through at least four general managers and six service managers in less than two years.
What would y'all do?

No 'misfires' are NOT normal. Thanks in advance.

First thing I would do Chief is find a new dealer, before I would give up. Then if the lack of security persists? Then I would consider trading in for a new Jeep, or whatever you prefer. Maybe even go vintage and simple? Whatever you choose good luck.

 

[JonMN]

thinking of trading too. That dam turn signal is just too loud.

Off to replace my transfer case and axles to resolve a misfire thanks to the tips in this thread!

One of the first things you do is an ecu scan a fluid service on anything to try and correct a problem. Lifetime fluids and all that stuff.
This was not an overnight problem. I have been dealing with it for months amd over 20k miles. And yes, I went to other dealerships.
Some of these so-called experts may know what to do when they see a problem. I'm not going to throw parts at an engine to see what works.
Knowing why something is a problem is pretty important.
Excessive misfires on cylinder 3? Cam related issues in the future. Sorry, not worth the risk to me.
I loved my Gladiator. Just not worth the hassle. I came on here as a last ditch effort to try and talk myself into keeping her. The lack of definitive causes to her poor running, by the dealerships and this online forum, was very telling.
Still love it but.....

But again, what you're dealing with is a specific case (and a very solvable one at that). To go from that to saying every single vehicle with this engine across the entire brand is trash just doesn't track. The PUG is statistically one of the most reliable engines out there. I would suggest you look at the Tacoma drivetrain failure rates and what it takes to fix them if you really want some applicable context. Nobody makes a mass-produced product exactly perfect 100% of the time. They all have risk and if it were me, I'd take a low-chance risk of misfires over an entire engine failure any day.

If you really wanted to switch to another truck I am never going to try to talk you out of it. I think you were looking for a reason, found one, and then came here hoping to get some sympathy and start a dogpile. Sorry it didn't work out that way.

Jeebus! What a bunch of butthurt jerks. It seems like the Jeep 'experts' won't except facts. These things are garbage. If you buy a new vehicle still under warranty it should be taken care of.
But, Jeep is owned by FIAT. Fix It Again Tony!!!!!

Well, I traded it in today. Y'all take care.

What do you consider excessive? This is not a case where we're saying 2+2=5. 1200 misfires in Cyl 1 in less than 10 seconds is excessive. 20 misfires in 30 minutes isn't.

If it doesn't throw a code, no one can help you at the dealership, basically.

There are many things that can cause misfires, ranging from bad gas to valvetrain failure. People here told you which solutions to go through systematically. I gave you a very easy diagnostic test to perform that would ID if the issue was "the big one" for the 3.6L and you've ignored it.

You're not interested in solving anything.

Good luck with the Tacoma. I hear they're completely error free.

I asked CoPilot to create an image of a Toyota Tacoma with no doors and roof and a driver. This is what I got (not a joke).

if you're buying a Jeep and expecting Toyota quality you're doing it wrong.

 

[guardrail]

The problem with different dealers is they all immediately go to their service and warranty computer system and conclude you are hallucinating.

my son had a grinding noise in the from end of his 4wd F150 for over a year. I finally got into the Ford system thru owner portal and checked for technical service bulletins. Bingo. The exact system in an 18 month old TSB. Printed it and took it to local dealer where we live and told them to perform the diagnosis because driving to it experience the problem never worked. Hallelujah. Replaced one hub actuator and vacuum check valve (it’s a crap design).

What octane gasoline are you running? Have you tried a couple of tanks of premium or adding an octane booster? Could there be water in the tank?

 

[smlobx]

So after reading all nine pages I’m left wondering when should you, as a matter of good routine maintenance, change the spark plugs and coils?

And as for the guy who was hating on Penske they just won the 24 Hours of Daytona in a Porsche!,
