3.0 Diesel Emission Issue

[redwngr]

 

 

[22sierra3.0Elevation]

2022 GMC sierra elevation with 3.0l diesel.  picked up  April 2022

 

1000 miles, emissions code appeared.  Took it to the shop and they said software update.  Code went away.

 

2500 miles code reappears and took it in again where they adjusted "software" again.  

 

Following week, code appeared again and they have had my truck since.   going on 5 weeks

 

Replaced, DEF filters, sensors and now they are working on catalytic converter.

 

GM engineer is using my truck as R&D at this point and getting a bit frustrated but at least they are making my payments and have given me a loaner.  

 

Was getting 30+ plus mpg on freeway unloaded, 25 when loaded up, gear and passengers

 

Ill keep updating but hoping this is the last addition before my truck comes back,
