NewDude, thank you for the suggestions! I did follow up and the dealer indicates he has an open CX case and is working with DPAC (Dealer Parts Assistance Center). Per the dealer, GM has had a quality spill and is not providing an update for when a replacement engine will be available.

I have a 2025 GMC Canyon Denali. On a trip recently the engine failed. The dealership diagnosed a bent valve and says there is a service bulletin that indicates to 'relace the engine'. The truck only has about 14K miles and is under warranty. The failure occurred 5/11/2026. So far I have worked with GM Customer Assistance and Roadside Assistance. Evidently no engines are available and nobody will offer a date when a new one will be. Coming up on two months with no repair or timeline and no loaner from the dealership. GMC Customer Assistance is 'ghosting' me and keeps closing the cases I've opened with no resolution. Hoping someone can help me on how to escalate this issue.
