I've never heard of one clogging with regular use and regen cycles. Maybe early in a model cycle, GM has adjusted the regen frequency but that was a long time ago.

The DPF is post-manifold as is "DEF". The additional equipment for the engine is the addition of an EGR, similar to how gas engines have had EGR for a long time.

In the last 10 years I've had a GM 2.8 LWN diesel and a 2021+ Cummins B9. Also a 6.6 2006+ LLY Duramax with DPF, but that was pre-SCR.
This is just one diesel mechanic I’ve been following, but they all are saying pretty much the same thing:

You might be having good luck or the way you drive and maintain your vehicles is excellent. Not doubting that. But in general, for the mass market and commercial, diesel has become untenable. Especially for a business.
