Just read that you were thinking of purchasing a Durango. My experience as a Durango owner was not a good one.I had a 2011 Citadel purchased new:

Engine failed outside of warranty -camshaft lobe went flat, likely from a failed lifter
Left wife left stranded a couple of times with small children due to an issue with the 4X4 Hi/Low switch on console. The switch was eventually re-engineered and the issue was resolved.
HVAC blew hot air on passenger side in the summer and cold in the winter
Sunroof replaced 3 times under warranty but never stopped leaking.
Rear hatch seal replaced twice under warranty but never stopped leaking.
Early corrosion around front door handles not covered by warranty.
To replace Hi-beam bulbs front bumper has to come off.
To replace battery front passenger seat has to come out
The rear hatch safety system to prevent the door from closing against an object failed so the door would close fine but then pop back open while driving down the road. Replaced every component in the system but the problem still existed so had to secure the door with a bungee from the hatch to one of the child restraint mounting points on a rear seat.

Build quality on these vehicle was extremely poor. I would not recommend this vehicle for your next purchase.

Worst vehicle I’ve owned and I have had a few lemons in my day.
