Been driving it today, running great. I'll be taking it to FL on Sunday, 600 miles down, 600 back.

Got the truck back. It actually felt and sounded like it was running smoother and quieter. Maybe I'm imagining it. Anyway, it's good to have it back with no CEL. Im posting 2 images of the the work they did.

Im a bit nervous though. Other than the 3 CEL's, it has never run bad at all, not once. 20 mpg on the highway, 16 around town.

When I dropped it off he brought up the star report on his computer, they already had another Gladiator in there last week with the same exact issue. Did you say that you noticed a difference in the way yours ran afterwards?

The Check engine light was a flash update. They're now checking on my flashing rear differential lock light.

Well, day 2 at the dealership. No word yet.

Thanks! I'll report back on their findings and solution.

I read the hot restart misfire pdf, I’m not a mechanic, so what did they do? Is it a software update? I’m asking because I’m printing out that pdf to show the dealer tomorrow. your situation is exactly like mine.

Correction, the Jeep only sat around 10 minutes, not 20, before she took it to run errands. CEL came on at that time.

Okay, CEL came on today (not flashing) exact same scenario as the 3 previous times. Vehicle was driven and completely warmed up when we came home. 20 minutes later the wife takes it to run an errand and the light comes on. She brings it home and I take it out to see how it’s running (CEL is...

What did they do?

My first occurrence was on a trip to Florida towing a boat.

you and I have had this discussion last time, our situations are almost identical. Im driving it today, and I'll schedule a service this week. There's no CEL right now so there might not be a stored code from yesterdays incident.

Yes, that's what happens with mine. Did yours run rough when the CEL was flashing?

Well, it finally happened again, almost a year since the second flashing CEL. (P0300) This time it came at 18000 miles, same exact scenario as the other two. Had driven the truck in the morning, came home and parked it for approx 20 minutes, left again and the CEL began to flash as I was driving...

Im glad you got your P0300 fixed. When mine happened the second time this past Summer, Jeep engineering did not have a fix yet, so they cleared the code sent me on my way. My vehicle never ran bad and has been great even withe the 2 CEL's that I had. It will happen again when the weather gets...

Great idea!

Thank you. Yes, my 2 instances were in 80+ weather. Wife just drove it to Birmingham last week from the Atlanta area and back with no issues. If and when this happens again in the Summer, I'll take it in for the fix. Not going to mess with it until then. I love this vehicle, my wife has had to...

You and I have discussed this earlier in this thread, my issue is identical you yours. Mine has been running fine since my last Flashing CEL (P0300) in August. At that time the dealer said Engineering had no fix. I haven't taken it back for this latest update that everyone is talking about. Ive...

Mojave is best Jave.
