On XXX, while driving at highway speeds, the truck unexpectedly shifted into neutral, causing an immediate loss of propulsion. During this event, the electrical system was also affected. The battery power dropped, power steering assistance was lost, and due to the electronic push-button start system, the vehicle could not be restarted while in this condition. This placed me and surrounding motorists at significant risk of a crash.  I initially brought the vehicle to Point GMC, where I was advised no issue was found. After the problem continued, I returned on XXX and a dealership technician rode with me. During the test drive on [XXX], the truck again shifted into neutral, confirming the defect. The vehicle was then towed to the dealership, where diagnostics revealed DTC P0016. I was informed the engine had seized and required a complete engine replacement.  The engine was replaced by an authorized GMC dealership in New Jersey. After only about 2,000 miles, the check engine light returned and the vehicle began experiencing additional electrical issues. This is a Denali Ultimate, the highest trim level, with advanced electronic systems, making these recurring failures especially concerning.  To date, the vehicle has been inspected by three authorized GMC dealerships, and I have opened multiple cases with GMC Corporate. Despite repeated repair attempts, the manufacturer has not provided a permanent resolution. I continue to experience recurring engine and electrical issues and no longer have confidence in the safety or reliability of this vehicle. Given the repeated failures, loss of propulsion, loss of steering assistance, inability to restart the vehicle, and lack of resolution after multiple dealership visits and an engine replacement, I believe this matter warrants investigation by NHTSA.
