ENGINE
Potential Consequences:
At approximately 500 miles, the vehicle started to shutter and misfire at highway speeds (60-70 mph). The check-engine -light began to flash at the same time. We have a video and this happened 3 times before taking it to the dealer. This is a safety concern because it began to lose power on the highway. The issue was confirmed by the dealer and found to be damaged connecting rod bearings.Gm engineers are aware of the vehicle and would not approve the ordering of a new engine by the dealer until the engine was completely torn down to the point of failure.

POWER TRAIN
Potential Consequences:
I would like to express my frustration and concern regarding a serious issue with our brand-new 2025 Yukon Denali truck. The vehicle, which has only 934 miles, has experienced a transmission failure. We picked the vehicle up on [XXX] and since February 27th, it has been at the dealership for repairs—now more than a full month. Initially, the torque converter was replaced, but that did not resolve the issue. After only a mile or two of driving, we returned the truck back to the dealer for further evaluation. Subsequently, after consulting with technical assistance, the dealership confirmed that the valve body needs replacement. As I'm sure you're well aware, this part is backordered nationwide, adding significant delays to an already troubling situation. It is hard to comprehend how a brand-new truck can fail virtually right off the assembly line. I am disappointed that we have had to deal with such a significant defect and even more disheartened by the extensive wait for repairs. This experience has left us questioning the safety and reliability of our vehicle. Given the circumstances, I believe more should be done to resolve this matter quickly and effectively for us. GM has been well aware of this transmission for years. The most recent recall dated December 13, 2024 for the same issue on the 2021 – 2022 model years of most of GM’s product line suggest this problem has not only been a known issue for many years but with the failure of my new vehicle for the same issue proves that they have not done anything about it. This leads me to believe that my safety is just as at risk as anybody else in the earlier named recall and therefore this recall should be extended to include all current models. GM should be forced to resolve this issue for existing vehicles before they build any new defective vehicles and sell them to unsuspecting customers like myself. Thank you for hearing me out, I look forward to your guidance. Jason FYI there is an interesting article o INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORM

Defect Description:
ELECTRICAL SYSTEM
Potential Consequences:
The digital instrument cluster blacks out randomly at times going down the highway. This is a safety concern because you can't see how fast you are going. The problem has been inspected by and confirmed by a dealer service center. The failure began without warning and seemed to occur after the car went through a GM software update. The service manager for the GMC dealership said this is likely a bug that GM will have to solve through future updates. The car's electronic system was reset but the problem persists.
