I'm posting again about my 2019 GMC 2500HD Denali Duramax with excessive DEF usage. I have just over 57K miles on it now and just returned from a trip--NOT towing. After GM replacing DEF injector nozzle and updating software and me paying to have NoX sensors replaced, I traveled 3614 miles, used 199.79 gallons of fuel and used 6 1/2 gallons of DEF. Has anyone heard of any recalls, updates, TSB's or anything that can help me reduce my DEF usage. I'm purchasing bulk DEF now so not so expensive but I still have to think so much DEF going into the system can't be good.

Thanks, I started out in the 2500HD forum, I don't know how it went to the 1500 forum.

Yes, In the grill. I really like how it mounted in and the view it gives me.

I have the camera system in my 2019 GMC 2500HD Denali duramax, the trailer has to be connected and the lights have to be on for my trailer camera to work. The trailer camera has to have constant 12v power to work and mine is supplied through the light circuit. I later added the front camera, you only need the add-on camera ($200) if you have the camera system installed, not the expensive ($580) complete front camera system.
