I had the Commander (4.7L, QTII) in for the recall less than two weeks ago, dealer performed the "reprogram final drive controller" reflash.

This morning I went to use 4wd low (first time since reflash), and immediately got the "Service 4wd System" light. It did not engage 4-low.

Light disappears once vehicle is restarted but comes back immediately if I attempt to go to 4-low, and stays on until I turn it off and restart.

Has anyone else who has had the recall performed experienced this?

If you've had it done, you may want to check.

I have an appointment to have it looked at so we wll see what happens, and I will update as I learn more.

Check your 4-low before signing off on the repair/recall.

Thank you so much for posting this! I never thought of checking this but sure enough, I get the same message.

Well that sucks.

Aww crap! Mine's at the dealership getting both the recall fixed AND a 4wd light issue fixed. Guess I'll have to call them tomorrow and make sure it works prior to them returning it. Thanks for the heads up!

I bet a lot of Jeeps will be going back, they're fixing it in summer so i'm assuming most Jeeps haven't even been put in 4LO yet (if ever).

I am glad I read this.They are doing a software work around for a cracked PC board that controls the transfer case.The only way I will let them touch mine is when they agree to replace the module that controls the transfer case.This came up in a conversation I was having with an automotive tech I know.We had a good laugh about the software re-write to fix a cracked PC board.He worked for Chrysler for years and we had lots of laughs at the the way they did some recalls.We talked about how it could screw up the way the transfer case would work after the up date.I see from your posts that it did screw things up.

So Freddy, you aren't taking it in for the update? I was thinking about doing the same since they aren't even replacing the board

mine works fine?

I received the letter in the mail and i thought i would go on the forum before i brought my jeep in for update. Looks like i will be opting not to get "software Update"

Regardless if your 4WD is still functioning, (mine still works flawlessly) it's a safety concern. Lets say your jeep is sitting in your driveway and the T-case decides to shift into neutral, and your jeep rolls over your child! Will you then wish you had the recall performed?

How many times has this actually happened to someone that caused the recall?

the recall was performed on ours just before we got it.. and it works fine.. put it in 4lo the other day to load it on the rollback to go get windows tinted.. it was raining on the aluminum bed and all it wanted to do was spin.. so i locked it in 4lo and it climbed right up not a problem

So should I get it done or not?

Mines goin in Fri morning... I'm gearing up for a fight.

Had the recall update done today. Tested 4Lo before and after. No issues so far. I'll be sure to keep an eye on it.
