Just a head's up for y'all.
I brought my D in for regular maintenance over this past weekend, and they informed me that "RRT 14-050" needed to be performed. (This is also listed as TSB 08-053-14a). Applies to all '14 Durangos / Grand Cherokees built before May 6, 2014.
Normally, TSBs are not performed unless a customer comes in with symptoms that fit. However, my understanding is that any TSB that as an RRT ("Rapid Response Transmittal") must be performed, similar to a recall.
The only symptom I recall that I may have witnessed myself is the "significant delay to update the ambient air temperature display."
I have noticed in the few days since the update that my auto climate control seems to work much more reliably than it had in the past. Up until now it seemed like there were times when I would have to move the temperature up or down much more than I would expect to get the desired effect. For example, if it was 65 degrees ambient and my temp control was set at 74, it would often blow colder air than I would expect. I would have to nudge the temp up to 80 in order to get the colder air to stop.
If it is either very hot or very cold outside it didn't seem to be an issue...but if the ambient temperature was "average" is when I would notice this most.
Anyway, now the HVAC auto temp control seems to work much better. Just change the temp a degree or two and the temperature and fan act as I would expect.
So if your HVAC auto temp control just doesn't seem 'right' to you, make sure you get this TSB / RRT performed.
Just a couple notes: On the trip home from the dealer, my HVAC was acting strange and blowing hot air continuously when in auto mode. This corrected itself after one or two engine restarts.
Also, check your system settings. After the update, some of my settings for locks, horn, and lights changed, so I had to change them back.
