There have been a few occasions where I have gone to precondition the battery and had some extremely interesting behavior happen on both of my 4xes. I was finally able to capture and log what was going on. When I precondition I do the following. Vehicle plugged in to L1 (or L2) EVSE. Turn on...

The oil life monitor in modern Stellantis vehicles is the “Enhanced Automatic Oil Change Information” System(EAOCI) All we see is the oil life % but there are 100’s of other values the system takes in to account when calculating the oil life %. I’ve been logging oil life parameters for quite a...

There has been lots of talk and debate about what temperature the 4xe will no longer operate in electric mode. The general consensus and through testing is that -12c or 10f is the threshold for the vehicle to operate in electric mode from an Ambient temperature threshold (providing other...

Hi all. Today is the day. I finally got my appointment at my dealership to have my steering damper (what my dealer tells me causes the death wobble) replaced. In addition, like many of you, the cold weather has thrown the hybrid mode out of whack so now when the vehicle enters FORM, it never...

So, I know there is a TON out there on FORM and how to get out of it. But, here’s a new thing that I can’t find anything on: As I was highway driving to get out of FORM i was going 65ish and I just toggled from hybrid to e-save. Pointless, formwise, I know, but just testing everything...

I have a Rubicon currently not in FORM and a Sahara Currently in Step 2 of FORM. I’ve logged PID parameters for months now trying to find out where the triggers are for FORM. My initial monitoring parameters seemed to not be the proper ones. Once my Sahara first went in to FORM a few weeks...

I made it to FORM! While I’m happy about that I’m less happy that I don’t think I’m any closer to figuring out what parameters are being used to trigger FORM to work. The last week I figured out my 2021 Sahara has done 18 starts or trips where the engine oil did not get warm enough. Today, It...

Well here’s an interesting update that I was hoping I was not going to have to make. Ambient temp is -8c At the time my temperature sensor was reading reading -6c. Oil temp was 0c and coolant temp was 0c as well. I had just driven in electric mode, parked at a store and went in for...

Winter Cover testing without the winter part! I previously did the same drive with my winter cover on testing out different methods of getting the oil up to temps that should clear FORM. The instructions for the Winter Cover state not to use it in temps above 40f (4c) I decided to ignore that...

If you were thinking about getting the Mopar Winter Front Cover for your 4xe it might be worth it. Here are some initial tests with in, keep in mind your results might not be the same as mine. Ambient temp was 8C and there was a crazy tail wind 70-80kms/h pushing me down the highway. Speed...

It's pretty much summer temps now in western Pennsylvania. Weather in 60-80F range. Driving history for first 2600 miles has been primarily electric with a few longer trips thrown in. Just yesterday I put added a half tank of gas for the first time in 60 days (had run down to 1/8 full)...

This beauty has been the most fun, enjoyable vehicle I’ve ever owned. It has been perfect in every way except for one annoying problem that I’m looking for advice on. My dealership couldn’t help, so now I’m reaching out to the community. The Jeep enters Step 1 of FORM every ~3 weeks. It goes...

I THINK I FOUND A FIX!! HIT THE ELECTRIC BUTTON IMMEDIATELY AFTER YOU HIT THE START BUTTON WHEN STARTING AS NORMAL WITH YOUR FOOT ON THE BREAK.

So let me preface this by saying I do live in Wisconsin and yeah it's cold, -5 fahrenheit today. Anyways, I know FORM and ICE are issues with hybrids but I didn't know it'd be this bad. I've tried all the tricks. Got my oil temp to about 205 for around 20 mins and it never kicked off. The...

So I’ve been a little frustrated by the FORM issues, and with the winter here in the northeast, I can’t consistently get my engine oil temp high enough - for long enough - for the electric to kick in. I only commute 8-10 miles to work each way, so it’s not gonna happen. I loved my 4xe in the...
