I just checked on Jeep Grand Cherokee WK2 - 2011-2016 Grand Cherokee Service Bulletins and Recalls
and there is a new TSB posted as of last Friday 7/11.
I had not had any updates done since the beginning of the year and decided to stop by the local dealer.
They applied 2 update:
TSB# 18-018-14c (RRT# 14-028)
TSB# 08-053-14a (RRT#14-050)
I was having issues with the oil life gauge properly calibrating. Hopefully this is resolved via one of these updates.
