Welcome to NICOclub! I hope you enjoy the Armada/QX56 Forum.Hmmmm, all I can say is that if buy the Armada with the Tow Pkg. from Nissan, it incudes the following:
- Tow receiver hitch
- Lower final gear ratio
- 7-pin wiring harness
- Trailer brake pre-wiring
- Transmission temperature gauge
- Heavy-duty battery
- Auto-leveling rear suspension
I don't know if any of those features have anything to do with the issue you are running into. If I were you I would call a Nissan dealer and see what they have to say about your problem, I know you were looking to us for advice, but I can't think of anything else. Good luck and let us know how things turn out!
