...That is an assembly line where specialized techs focus on their respective tasks (thank you Henry Ford). The disassemble and replacement of my battery will not look like that. This will be done by one or 2 dealer techs who may or may not have been trained and are now doing their first Bolt battery replacement. If the dealer or GM want to prove to me that experienced techs will do the work then that would be great. But it doesn't change the fact, Chevy gave me a defective car right out of the gate. There is a simple way to set this right. If they want the car to study and make sure it doesnt happen to anybody else then have at it...I simply want what was promised.
Frankly I think replacing the entire battery pack is a good deal for you compared with what might have happened. They could have instructed the dealer to troubleshoot individual components inside the pack for service, for instance.
As far as "diagnosing" car problems these days most technicians' skillset consists of pulling a code, looking the code up, and doing what the service manual says to do. The actual code (or combination of codes) tend to be the extent of what can be determined short of some major component failure where the magic smoke gets let out. The systems involved are simply too complicated, even if you get the rare tech with "calibrated eyeballs"...
Mind you, I'm sure that battery will go back to Michigan for a complete tear-down and failure analysis.
Replacing parts (even major ones) is well within what the systems and processes in a manufacturer are capable of. Replacing entire units with serial numbers or VINs is a major exception in the process, and would probably take you longer than getting your current car fixed would. Basically, GM would have to buy your car from you (you bought it from the dealer, not from GM), then pay the dealer to sell you a new one. All your financing would have to be re-done (it all has the old vehicle's VIN on it) as well as insurance, title, license, etc. If you're in CA, I'm guessing you get to pay tax and registration again, too!
I know of very few cases where a manufacturer has come out and replaced a vehicle wholesale. One instance I can think of is some of the early Tennessee manufactured LEAFs had a mis-welded front suspension member that would have been so difficult to repair they simply replaced the cars. In this case, it was a major safety issue (the front end could have detached from the rest of the car!) and a federally mandated recall would have happened in any case. In your car's case, the battery is a component that was designed to be replaced as a service item.
