2025 Yukon Denali Ultimate

[littlerich326]

Hello all,

So I am new to the forum. I was wondering if anyone would know if the new GMC Yukon trucks are still coming out with the same engine specs or has GM provided a deactivation of the cylinder issues being starved of oil ????

To my knowledge, the 2025 Denali has the 6.2L motor with the fuel management system (deactivation of cylinders) still installed and active.

Thanks for the reply . So looks like nothing was addressed on the engine from GM

That's why you order a Dmax and wait...

Call a dealer, why are you asking strangers on the internet advice before buying a $60k+ truck?
