Survey- For those with misfire issues

[JeepCares]

I also have the same issue. In shop now and they wanted to replace engine. Jeep rep said no fix for now because engineers are working on a permanent fix. @JeepCares what is the permanent fix that they are talking about? Right now they were going to rebuild one side of the engine and they put it on hold for a permanent fix.

My Flawdiator has 1056 miles. Been in the shop twice, total of 8 days so far, for the code 0300 misfire CEL. Just came on again for the third time. Taking it to a different dealer tomorrow, maybe better techs. Also looking at FCA buying it back. I used to love this vehicle. Now I don’t trust it, which makes me despise it. @JeepCares

Update: the saga continues......with less than 600 miles, my Gladiator is still in the shop. This makes the 3rd time in a month of ownership for a total of 18 days and counting. CEL & ESS light. Dealership is now requesting a field engineer as no one, including FCA, have a fix. I’ve had a case open since my first incident, but FCA reluctant to make this right for the consumer. Will continue to update and unfortunately if I can’t remedy this on my own, I likely need to get legal representation as I’m getting nowhere with FCA & Dealership. @JeepCares

I also have the same issue. Traded my jeep gladiator sport for a Rubicon and by the first week of ownership i got the auto start/stop light and check engine light on. 1st time in the dealership and they claimed it was the fuel quality affecting the engine due to ethanol content. Got it back and a few days later same thing happened. Its a the dealership for the second time now within 3 weeks of ownership. They had the jeep for a week now and said they are talking to a jeep engineer to fix the problem but have not been able to find the problem. Went to try and get a rental from them and they claim that jeep did not want to approve a rental because they are unsure or what is wrong with the vehicle. Here is a copy of the first visit. Any suggestions on what to do?

Yes, disappointing to say the least and I’m sure the number of affected vehicles goes well beyond those of us on the forum. Tuesday will be four weeks they have had mine on trip #2 to the repair shop. Dealership is waiting on direction from corporate. Obviously no one knows what is wrong, much less how to fix the problem. Or, alternatively, corporate is hiding the ball and is afraid to acknowledge the problem.

Certainly makes you wonder because corporate is apparently not sharing any relevant information with their dealer network. They have had plenty of time to sort this out and to be more transparent about what is going on.

I am beginning to wonder if there is a way for us, as affected owners, to lodge an official complaint as a group with corporate.

@JeepCares — is anyone listening?

Make me #31, Mine started with the auto start stop service light. That was around 400 miles. Now I am at 4,000 and ther CEL has come on 3 times some flashing too. The work that has been done is
replaced secondary battery, charged both batters due to being quite dead but still derivable. replaced spark pugs and wires, updated the computer to the new software (in march). I called last week about the auto start stop system error again. told to drive it until the light comes on and bring it to the dealer. This past weekend the CEL flashed a few times and now has the P300 error code again. Off to put more miles on it so that they can have there error light. At this point this was not the "Jeep Experience" I was looking for. My old YJ that I was rock crawling was more reliable. Thanks to all that have posted. I hope one of us here can get this figured out.

Count me in if we want to go in together to file an official complaint with FCA. I also am seriously considering pursuing them buying it back, assuming all the dealer installed mods would also be reimbursed. Jealous of all the other owners who have had no problems.

Count me in as well. Pushing for buy back/replacement.

I wish they would tell us more about what they know about the problem and the fix they are working on. Even if there are no current fixes by now surely they have a pattern of the problem and something that can be isolated so all of these dealers aren’t just working blind. I believe my dealer has been working hard to find the problem. It seems so many different “fixes” are being applied and none are permanent fixing the problem. BTW I have not heard back yet about whether replacing the PCM was the problem with mine.

Heard from the dealership this evening. They say they have fixed the issue by replacing the PCM. They are supposed to deliver my Gladiator in the morning.

Hi, thanks for the update. I certainly hope this works as I remember this was done on a couple of others in this thread without success. Did they say if this was a “let’s see if this works” attempt or a STAR technician bonafide solution to this issue? It would be awesome if this actually works!

This was a “This should fix your problem” kinda solution. I can’t believe that If it really is the solution FCA wouldn’t come right out and just release a TSB about it. But this is fix repair attempt #3 on day 14 out of service. I’m ready to drive it, get my 4th CEL so we can settle this thing however that works out. Would be great if they can fix it but we know they can’t.

Is anyone getting surging or exhaust noise? I am just wondering if it is actually a misfire, or a harmonic that sounds like a misfire to the ECM. I believe the knock sensors, are under the oil cooler. The gladiator has unique heads, starter, and alternator. The misfire seems to be cylinder 2 most often. A guess I have is, one of these new components causes a harmonic in the block that sounds like a misfire, but isn`t. Be interesting to see if the jeeps with the Hamburg supercharger have this problem. It relocates the alternator. Another thought is, does disabling the ESS help the issue. Maybe the starter rattles the engine just right.

I have been running with my ESS disabled from the second day of ownership, and have not seen this issue yet. I also have been running the Magnuson supercharger kit, which changes the mounts to the alternator.

My Gladiators fix has now been escalated to field engineers as all are at a loss to remedy. I'm hopeful your fix does the trick. As stated earlier, mine is still with the dealer for the 3rd time for ESS/CEL issues. Day 20 and counting. Similar to you, I just want the truck back fixed, with concessions of course or let me get my 4th ESS/CEL so we can settle as well. Good luck all!

It’s interesting to me that I have not heard from the dealership today. How many days before you can file a lemon law claim in your state?

30 business days in MN or 4 times for the same occurrence.

I bought an overland Gladiator in November, before it had 400 miles I had my first misfire. Brought it to the dealership they kept it for three days just to clear the code. Have had 3 misfires since. Went to pick it up today after the dealership having it since June 4th (20Days). They changed a cylinder head,TIPM and ECM. When I started the Jeep it already had a new CEL for a misfire. Si at the dealership it remains. I am a lifelong Jeep owner and this is the biggest disappointment ever. This is the very definition of a Lemon and it does not appear Jeep is ready to do right by it. I guess thats why God made lawyers.

Hey everyone,

So I picked up my Gladiator today. They replaced the PCM. I asked a bunch of questions to try and get some information. There is some internal information on the jeep service network about this issue. I will report back in a few days if everything is still good. There was information about engine replacement and other internal work. Reported as electrical problem not as a mechanical problem. Replace PCM was the recommendation on jeeps service network.

It makes sense to me. I kinda though it was that from the beginning.

Steps that have been done to my Jeep.:
1: no codes just auto stop /start system service error
2: Misfire check engine light, cleared codes at dealer
3: misfire codes again 1 month later, Charged both Main and Aux batter, Codes cleared at dealer
4: Asked to come back when codes are active, Don't shut off the vehicle
5: Misfire code again, drove to dealer with auto start stop service error, misfire code, Active code P0607. This was only found with the jeep running, after the check engine light comes on and Auto start / stop service error.
6: PCM replaced at dealer.


I hope that this information helps others. I wish you all luck!

Spoke with service person at my dealership this afternoon. He said they replaced the PCM and have driven my Gladiator 2 to 300 miles with no CEL coming on. They think the PCM is the problem. They are supposed to bring the vehicle to my home tomorrow. If that happens I’m planning a beach trip this weekend. We’ll see if I make it there and back.
