In September I did a trip from KC out to the west coast and back through Salt Lake and Yellow Stone. Left on a Tuesday night and arrived home about 11.5 days later. Longest leg was the last one from Yellow Stone back home, about 1142 miles. Put a total of 4932 miles on the JT and 93.5 house...

Have over 5000 miles on the Gladiator since the TSB was applied. Drove from KC to Pasadena up PCH1 to San Francisco to Salt Lake to YellowStone and back to KC 93.5 hours driving in 11.5 days. No CEL and for the first time since I have had it, no random ESS light. So knock on wood, the TSB...

Just got the TSB 18-224-021 Update PCM software and replace Camshaft. This might be TL;TR and some of it is just a copy and paste of some old notes, so forgive any spelling or grammar issues. A little history as I have not posted to this thread for over a year, but have been actively watching...

Another update. Recap, It’s been nearly 3 weeks since I was told to drive my Gladiator until they have the software fix. It had a multi-cylinder misfire in cylinders 2, 4.6 and they were able to duplicate it a few times on a cold start. Since then I have put over 1000 miles on it with...

Agree, the temperature theory does not really pass the smell test for me. Why would I just start seeing the problem after 1,600 miles. Why would this not be wider spread since the Gladiator has been out long enough to be exposed to many temperature conditions. I've been a software engineer...

Service Department called back after about a week in the shop. Turns out they decided not to replace the engine, and the metal they found was actually in the oil filter, and FCA confirmed it was not the issue, and not uncommon. I believe others have posted in the forums they have seen metal...

There are a number of us who have this problem. Check out this thread and others. https://www.jeepgladiatorforum.com/forum/threads/survey-for-those-with-misfire-issues.24853/ They are replacing the engine on mine.

Update: Got a call from the dealership on Monday. FCA gave them approval to take apart the engine. They found a piece of metal which was disrupting the timing and something else, but I was so swamped at work I didn't catch all the details. He said they have a list of VINs and build dates...

The dealership acknowledged they were aware of others having the issue, they said they hadn't seen one in their shop until this last week. He never said it just started happening, just that they hadn't had any in their shop until this last week. He very well may be trying to just pacify me...

A quick update on mine. Later in the afternoon on the the 5/27 after I dropped it off at the dealership, I went to pick up a loaner and the dealership told me I had a multi cylinder misfire on cylinders 2,4 and 6 on a cold start. He said that tells him that it was not fuel related and "HE" had...

I ran my estimated range down to 5 miles on purpose a few weeks ago, and I didn't have a problem. Not disputing what they told you as I am no mechanic, but it seem strange. I have read people have had misfires in other vehicles when they let the gas run low. Sometimes due to low fuel...

I will add to the thread. Build date: Year 2020 (Based on VIN), Forgot to look at door sticker before I took it to the shop How many times has it occurred: 1 What exact codes: Don’t know, but technician said it was misfiring on a cold start consistently. Is the issue on going? Y Milage...

I tried putting it in Park also, I was probably too impatient, and didn't wait long enough the first time. At lunch I had to go and try to reproduce it without leaving the driveway. Had to have the door open to do so. My neighbor probably thinks I bought a POS since the 2nd day I had it I...

I know this thread is 6 months old, but had to post. First, thanks for everyone that posted their descriptions here. I am a new Jeep owner, just purchased an Overland 3 day's ago. So far I love it. Yesterday it spend the entire day in the shop because the Auto Start/Stop system maintenance...
