Check engine light

Whelp, I may have found the source of our awful fuel economy (averaging about 12mpg with SO Hurricane). Check engine light came on today and it threw about 16 codes all related to misfiring cylinders. After break-in I also noticed a full second delay between hitting full throttle and the engine responding. I thought that may just be turbo lag but have never experienced a delay like that before in any vehicle.

Hoping to get it checked out soon, but my local dealer currently has no service appointments available. Is this something Wagoneer client services is supposed to help with?

We are only at 1200 miles. Might legitimately have a lemon on our hands. Stay tuned...

Any update on this, @Meeno? I’m pullin’ for ya!

P.s. Disregard. Just saw your update on another thread. Enjoy the TRX and hope the Wagoneer stays trouble-free!

This exact same thing happened to me today. 2023 series II with 1600 miles on it. In contact with service department now.
Service assured me it wasn't actually misfiring, and that if it was you would feel and hear it. Code hasn't come back, but I did figure out the fuel economy issue is the computer is low by a good 40%.
