Another N23 victim

The dealer performed the N23 recall 2 months ago when it was in for an oil change. Of course I get a foot of snow dumped on me last week....and I get the '4WD service needed ' message when I tried to get into 4LO. Check out the problem on line, find out I'm not the only one. Called the dealer and I get the "Never heard of that happening" reply. I know it worked before, I put it into 4LO about once a month to make sure everything still works. So here I sit at the dealer, wish me luck.

You need to print out the threads on forums everywhere about this problem, then drop the resulting ream of paper on the dealer's desk next time in. Maybe the 5 lbs. of paper whamming down on the desk will wake them up!!

I love the way that works. Even in the radio business, it's the same crap. I won't mention any names here, but an Indian casino who uses HUNDREDS of 2-way radios in their system, from security guards to maintenance men, bought about 50 new radios. They're a new model, and suddenly we're getting dozens back with cracked cases. I won't mention the brand.

Call the manufacturer, they deny-deny-deny there's a problem, and we're the ONLY dealer who's EVER had that happen to. When we try to order new case assemblies, they're back ordered for months. Maybe, just MAYBE because there are dealers all over the USA with the same problem ordering new case assemblies?!? Say it ain't so.

Chrysler execs will deny to their graves there's anything remotely related to sudden $800 controller failures right after the update, despite Jeep owners everywhere having problems within like 5 minutes of said updates.

When I went in and told the service writer what was wrong, I kinda got that 'whatever nutcase' smirk. Two hours later I'm told this was a problem that she didn't know about, it'll be covered, but there are no parts available to fix it. They'll call when the parts come in. If I'd known it was going to take two hours, I would of gotten my oil changed while I was there! So good news, to bad it took all morning.

Two months later, the new motor finally arrives. It was put in today, and everything seems to be back to normal. What a pain in the butt!

service 4WD fix

Need to try this It works
This is what worked for me after getting the n23 recall and getting the dreaded service 4wd system error when I try put it in low.

1. Turned my car on (engine running) checked that the 4wd service message was still occurring when I activated the low 4wd)

2. turned my car off keys out. opened the bonnet.

3. Went to the fuse box under the bonnet took fuse labelled fdcm/ediff

4.Shut bonnet, got in my car, started it with the fuse out put it in drive, drove 2 meters forward then put it in reverse drove 2 meters backwards. (Be aware you will get the service 4wd light without pulling up the lever as you are driving)

5. Turned my car off keys out went to the bonnet put fuse back in shut bonnet

6. Started my car put it in drive got the car rolling just below 5 mph (as this makes it easier to slip into low 4wd read manual) placed it into neutral while rolling activated the low 4wd switch and it worked!

You will have to put your Commander back to stock tune before you have the recall done. Then put your custom tune back after the recall.

Thanks for the advice!! But in your opinion is really necessary for me to do the recall N23 ?
I ask you that cause the place where i did the module tuning is far from where i live and ll be complicated....

Thanks

I have not had the recall done on my Commander because of the problems it has been causing everyone that has had it done.

I have not had it done to mine nor will I go to the dealer unless I know that the problem is fixed, but I do not have remote start.
