NHTSA Complaint #11691941 — 2018 CHEVROLET CAMARO

I lose power steering randomly. When this occurs I get a service rear diff message on my dash, the fan motor cuts out, and gauges like the speedometer and tachometer go to zero. I took it to a dealer because I saw there was a recall for the exact problem I'm having with power steering, but I guess it's VIN specific and my car is not included in the recall. They also told me they couldn't get it to reproduce the symptoms I was talking about but after I left 10 minutes later it did it in a Walmart parking lot. I got it on video. This has caused one almost serious accident and multiple minor ones, and I can't afford the expensive dealer diagnostic fee and repair. I don't feel safe driving with it. I'm confused why I have the same make model and year of the recall but mine's not included. I called GM and the lady I talked to just kept repeating how my van wasn't included in the VIN specific group, and offered no help other than to go to a dealer and pay them to fix the same problem that is covered by other cars of the same year, make, and model. I asked her if it was possible that maybe their VIN groups should be expanded, especially because it's an 8 year old car and the recall just happened like 6 months ago, so maybe they didnt have all the data or info when they made the group of effected vehicles, and she hung up on me. Please help.
