2020 3.0 duramax in the shop with 140 miles and a bad dpf already


Recommended Posts

I picked up a 2020 Denali 1500 duramax on Wednesday and here it is Friday and it’s in the shop for the next 2 weeks.

p2463 code and they are thinking it’s a failed dpf.

they gave me another Denali to drive for now but only after I threatened to take my 4Runner back.
