Another Coolant Low Service Bulletin 18-NA-006
So I have been having the loww coolant warning for the past week. I have put almost a half gallon of antifreeze in it in the past two days. Took it top the Dealer this morning, and they just called to say that they can't find a leak, and infomred me of the fill issue at the factory bulletin. I explained that I feel this should have been recitfied in the 42K miles that the truck has on it. The lady advisor stated that this just came out in July'18.
So I am confused as to why this is just now happening, and also I have noticed that the RPM's have been elevated like it is constantly in Regen mode. She stated this morning that only they can make the truck go into Regen. I guess, I'm not aware of this fact. Anyone know of this fact?
Anyway, if anyone has any info on this TSB, please let me know. I haven't found anything on it yet.
