Denali Reserve package "downgrade" between MY2024 and MY2025 Yukon?

[WalleyeMikeIII]

The more that I play around with GMC Yukon XL configurator, the more I believe it might be subtly broken for MY2025 Duramax builds.

For example, according to GMC Fleet Guide, one should be able to configure MY2025 AT4 with LZO (Duramax) and PEH (AT4 Premium Plus).

However, when I try to do so online, the addition of PEH automatically removes LZO. Anyone else see the same?

So, now I see problems above with both PCN/Z6E on Denali Duramax, and PEH on AT4 Duramax...

Is it possible that MY2025 Yukon XL Duramax configurator is not working properly, given that GMC is only just starting to accept those orders. Would love others to weigh in here, especially with comparison between online configurator and GMC Fleet Guide (linked above).

Thanks!

I’d say just ask your dealer. It is possible it is broken.

Thanks, but I don't have a dealer, yet. I never talk to dealers until I'm ready to negotiate for exact car I want to buy. I find I do much better on discount to MSRP through that process... (Usually close within 4-8 hours of first contact as there's no wasted back and forth.)

Welcome any other ideas.
