Just bought a brand new 2022 DT Ram 1500 Rebel on Friday. It had 58 kms on it. Side note: I actually work in the parts dept at my local CDJR. Tech brought it in for diag today and I had 2 stored codes for the rear axle. He clears codes and kicks it out. Leaving work today, I start my truck and it’s back on. Has anyone had any successful fixes done on this issue? There’s no service bulletins or anything. I’m starting to think I shouldn’t have traded my Chev

A brand new truck? Assume this tech verified there’s diff fluid in it? Buddy of mine fried a diff with no fluid in it on a test drive with the salesman in the car in a hand built car. It did a nice little spin into the oncoming lane and ditch when the diff seized. Needless to say he didn’t buy it!

ok did they check why you had 2 codes or just reset it??? if thats the case go somewhere else, and having one problem and saying you shouldnt have traded in your chevy is well not thinking things out .problems will occur in new vehicles chevy included get the problem resolved and you may have many happy miles with your new purchase .

FCA/Stellentis has a rep of shipping them low on diff fluid,it's very common in the Challengers and Chargers,so that should be your first check

Our best tech verified there were no issues with the connector. There’s an actuator inside the diff that’s part of the case and cannot be serviced separately. We ordered a rear case and he found the problem instantly. Chafed wire for the win. Since changing the case, it’s been working great.

My 22 Laramie with off road package and only 3700 miles is doing this too. This needs to be fixed. It happens at least 1 time every trip now. However, I bet the dealer will say they cannot duplicate it.

Had this problem too, it’s the fuse. Buy a new 15a fuse and you should be good! The service 4x4 will clear and your axle lock will work again.

First question i have ,is why did the fuse blow,was it because of a wiring issue,high amp draw etc. There's always a reason why a fuse blows
