2023 3.0 LZO trailboss diesel

[BigJake]

Just curious if anyone is having any problems with the 2023 diesel (LZO)the only thing I have noticed on mine does not like to be plugged in above zero degrees or the cooling fans come on high speed, the only fix is a 6-hour cold soak or disconnecting the battery, this is a fairly common known issue, with hopefully an update in the works.

I think this is what you are talking about. I don't have a Diesel, but watched this video.
