NHTSA Complaint #11697262 — 2025 GMC YUKON

My vehicle, with only 2,400 miles on the odometer, has been diagnosed as requiring a full engine replacement. While driving on the interstate, a warning message appeared indicating reduced acceleration. I was able to exit the freeway safely, but the vehicle could no longer maintain adequate speed to match traffic flow. Prior to this, the check engine light came on, but no issues were reported in the vehicle’s status system. I contacted OnStar, and they advised me to take the vehicle to a dealership within seven business days. It has since been at the dealership awaiting parts. Upon further research, I discovered that this issue appears to be widespread. General Motors has issued a technical bulletin addressing the problem, which involves complete engine replacement. Additionally, the audio system intermittently emits a loud crashing noise that is startling and potentially dangerous—it has caused me to veer off the road due to its intensity. This issue also seems to affect other 2025–2026 Yukon and Tahoe models.
