I've had my share of experiences with Jeep dealers! The one that pissed me off the most was an extreme underfill on my transmission. I don't believe the newer Jeeps have a way to check this any longer.
But this is precisely why I stopped taking my Jeeps into the dealer for oil changes. Brakes, 30/60/90 service intervals, the dealer service center makes sense.
I don't believe you have to have the dealer change your oil to keep the warranty. That was another myth I had to overcome. But doing your own oil changes might save you some headache and give you satisfaction of a job done right. It also doesn't take very long once you get it all dialed in.... Although the SRT might require some ramps to get underneath. My WK is high enough stock that I can slide underneath and pull the plug.
Anyway, just a suggestion.
Nice looking ride!
