2021 gladiator pentastar 3.6L engine light

[Justinmocek]

Hey everyone I’m having some serious issues with my gladiator which only has 4589 miles in it. These are the codes. It has already gone to the deal once for this issue and they replaced bank 1 o2 sensor and now it’s happening again but only worse.

Why don’t you take it in for the dealer to fix and document in case it turns out to be a lemon?

It’s at the dealership now. I have called jeep customer care and roadside assistance 20 times in two days to try and get it towed and no one ever showed up. It has been a very frustrating experience with Chrysler.

Sucks to hear. They should at least repair it once and for all or replace it for you. I would ask o speak to the manager or owner of the dealer.

Have you done any mods? Like a cold air intake, K/N filter or something?

Some of the codes are pointing to a vacuum leak at the intake manifold. The O2 sensor was probably cheap and easy to replace, but it's rarely the issue - especially at <5K miles.

Ugggh, they have completely changed the airflow model, and it definitely shows in some trucks

I have no mods done. The only I have done is a lift kit and tires

I agree. I plan on going up there Monday to talk to someone. I know this is a reliable engine and I guess that’s why I’m sitting here scratching my head trying to figure out what’s going on. It seems to be a common thing for the gladiator from what I’m seeing.

And all the issues started after the deal changed my oil.

This is possibly an important piece of information. With that being said I would carefully check you air intake tube joints for leaks. They may of loosened something up on accident checking the airfilter. If the air intake temp is off it could throw those codes.

Thank you DAVECS1. I will check that on Monday as well.

Jeep assistance??? it will cost you to tow to the nearest dealer! (not who I purchased from)
Dealer was like "oh well, what do you want me to do"
2037 miles? really... This is my 4th jeep
Those who say pentastar, this is my 3rd and second with issues... Junk motor in my opinion!
Once fixed the gladiator will be replaced, diesel or 2.0

I have been in contact with jeep assistance and have expedited the process. I got my jeep back last week after 2 weeks of being at the dealer. I drove it one day and then left for vacation. Hopefully it’s fixed. If not they said they are going to buy it back.

So what did the repair order say they did to fix it?

Too much to type so here is the work order.
