I figured I would update this. Long story short I still do not have the car yet.
Shortly after I was able to track my car to the Charlotte rail yard in my last post above, I saw on 6/6 that it had moved here:
Being new to this experience I thought “cool, it’s in a new spot. That must mean it’s on its way”. I quickly had my bubble burst when Laborsmith replied in the
tracking with OnStar thread “Interesting. You have returned to the assembly plant.”
It was back at the assembly plant for quality inspection. Laborsmith said
here Chevy does not admit to a specific issue that is the reason for a quality hold, ever. My Salesman was able to do some digging around and heard that GM received 18 to 20 torque converters that may not have been machined properly during my built week. They likely recalled my car from the rail yard to check it over and make sure it had the correct parts. While I appreciate they wanted to send the car out right it’s added some frustration.
On 6/13 the car moved slightly over to this holding area adjacent to the plant:
On 6/16 they moved it back to the Charlotte rail yard:
On 6/17 they staged it to be loaded on a train:
And that's where my car is still sitting as of right now

. Saturday morning I go on vacation for a week out of state. I was hoping I would get the car before I left but it looks pretty unlikely it will make it to CA by Friday (which is 1 month from the build date exactly). Now I have to face the prospect that it may arrive while I'm gone but Vince my Salesman seems pretty on top of stuff so I'm sure it'll be safe there if it does. I may have to ask him to go home with both sets of keys every night though!
Thanks for sticking around for the read. Does anyone in Southern CA know once it's underway how long it takes for the rail portion of the trip and trucking to the dealer lately?
