NHTSA Complaint #11639086 — 2024 GMC YUKON XL

I was driving on the highway and my car signaled a "Low Oil Pressure". I pulled over and checked the oil level which confirmed I had the proper amount of oil in the engine. I turned on engine and began to drive again. Five minutes later I got a warning saying "No Oil. Turn Engine Off" and pulled over immediately. Had the car towed to GMC Beck and Masten Dealership the same day. Next day GMC Beck and Masten dealership ran diagnostics and didn't find any issues other than confirming the computer showed some "communication issues". They reset the computer system and called me and said I was good to go. I picked up my SUV and a mile away from home I notice the oil gauge was almost at zero. As I turned slowly to my street the SUV just stopped moving in the middle of a road while an 18 wheeler was behind me in a construction zone. 18 wheeler had to swerve to the right to prevent hitting me. I had the car towed again. The week after dealership called and said "you will stay in your rental and we are ordering an engine" casually. I called to understand what was going on but had to look in car forums to realize this was bigger than just a glitch in one car.
