Wagoneer Series III Shuddering

[MetilHed]

So my dad just got his 2023 Wagoneer Series III with that Hurricane engine last month, and we took it for a spin on a family road trip last weekend. It’s been kinda shuddering when we’re going uphill or trying to pass other cars. We took it to the dealer, but they couldn’t find anything wrong. Anyone else run into this problem or got any clue what’s up? It’s seriously bugging us - like, for a luxury ride, this shouldn’t be happening!

I had similar issues with my 2023 WL S3 that were getting progressively worse. Look into TSB 09-010-23. They just took care of it, and it seems like everything’s back to normal now!

Got it, I’ll look into that. Thanks a bunch!

I had the same issue with my 2023 Wagoneer, and once they updated, everything went back to normal. Hopefully, that will fix it for you too. If it doesn't, maybe ask them to check the transmission or the torque converter.
