NHTSA Complaint #11637626 — 2023 GMC YUKON

The complete engine on this vehicle was replaced by GM on 04/05/2024 at 24,069 miles. This was due to the known engine failures GM is having with the 6.2L engine. This is a well known and documented safety issue that GM is refusing to properly address. Vehicles with the 6.2L L87 engine are having complete engine failures while driving at highway speeds, which is a huge safety issue. I live in north Georgia where the roads are steep with sharp blind curves. I frequently cross steep mountains with high elevations that require frequent brake usage and constant steering through the sharp curves. I also drive on the interstate in Atlanta, GA where the posted speed limit is 70MPH. An engine failure in any of my driving circumstances is life threatening. As you know, when the engine fails you're braking and steering capabilities are greatly reduced. For example, if I was to experience an engine failure while driving across the mountain I would be unable to stop or get the vehicle off the road. Without being able to move, I could be stranded in a blind curve where I could be struck by another vehicle. I do not feel safe driving this vehicle and I'm in constant fear that it will have another engine failure like so many other 6.2L owners are experiencing. I'm morally unable to sell this vehicle to someone else due to the known engine failures. GM will not take responsibility and fix the issue or buy it back. So, I'm stuck with a $90,000 SUV that is unsafe to drive. Please continue to investigate this safety issue! You are saving lives by doing so. Thank you for everything you have done and are continuing to do. Please let me know if you need additional information or I can be of assistance.
