Rear differential

Yes! Twice now - but they cannot determine "root cause" despite finding discoloration in the fluid and metallic debris! UGH!

Has anyone else had their rear differential go out? Mine did today at 800 miles. Being replaced.
Mine hasn’t completely gone out but it seems like the differential is becoming a common issue, among other things. 😡 Mine was making a moaning/binding noise that went away when dealer service cleared and reset the computer. It is now back, and I have an appointment next week. On the WagoneerFans site, a member said this in a known issue now, and he has an open STAR case with MOPAR regarding the problem. STAR case S2121000019. I’m going to assume it’s related, and it might be worth mentioning to dealer service so they can look into it. The growing list of issues is making the purchase very regrettable…

Update: Engineering came to my dealer to push out a "test" of a differential software patch (made it sound like this is the one in development for push this quarter). I haven't got vehicle back yet - but they are reporting "good" results. Will advise and post tech notes when I have them for others.

My GWS3 went in Monday to get a software patch to fix the intermittent "service 4WD" error I was receiving. Engineer came up from Jeep to apply the patch - completely fried the drivetrain module. Apparently, this has only happened in 2 other cases of applying the update. No replacement modules in stock, waiting for assembly plant to get one to the dealer. Only issue I have had so far, but it is a little concerning that it happened. 2 of the first 5 GW's my dealer has sold has had the Service 4WD/differential issues.

WOW! disconcerting for sure. Now I'm paranoid. I'm hoping to get my unit back today - following the engineer who came and "pushed" the software patch! Keep us advised @mgrossi31

How much is Stellantis paying all of us first year buyers to "test" their new vehicle. Glad it's getting fixed Skip but this is ridiculous.
Side note - if you haven't joined the Wagoneer or Grand Wagoneer Facecrook groups you may want to. Lots of good info. Only downside is a lot of spam from dealers.

I agree Stellantis should take care of we first year customers essentially testing their product. Take Infiniti when they decided to break into the Large Lux SUV market in 2004.

I traded in two Durangos when I purchased the first year Infiniti QX56 (now badged QX80). They had one item, ONE item as a problem. The brakes wore out faster than they predicted. The first thing they did of course was recall all of them and replace the brakes with stronger roters. Then when ANY of the first year owners traded in for the next QX they GAVE the owners 10K from Infiniti, not the dealer. I was the first at my dealer, shocked him as I'd already negotiated my trade in plus the new vehicle price. He came out, showed me the credit Infiniti had on the books and said, deal is a deal, take it plus the 10k. He had what he negotiated for profit, I had a great deal. It basically saved the depreciation that happens when you drive off the lot, and that equity rolled into the next and the next. I've owned QX56/QX80's ever since. Even got a Mini-Me for my wife (QX60). :LOL:

Stellantis should learn a very valuable way to generate repeat business from Infiniti's approach when they broke into the Market. They could even make an advertizing campaign about it when they roll out next year's version, brag about what WCS means at Stellantis, what they did for all the first year customers who 'believed in the Stellantis brand', etc. Heck I could write that campaign and I'm not in marketing!

Same boat. Been to service 5 times in 3 months. Towed twice.
