I have been following this thread, even though I am not impacted in the slightest, as the issue is really strange to me. The label of a product by the manufacturer of said product is supposed to be something that can be relied upon being accurate at least to the part number of said product.
Its one thing if the label fell off or isnt present, thats a different discussion that the label being flat out "wrong item" on it. If I was in OPs shoes, I think I would be very upset and frustrated. This seems very cut and dried to me from the information presented. "Paid for part number X, Part installed has label for part Y on it".
At a very minimum I would want the label for part Y removed by tesla and the proper label for the item I paid for placed on the product, by Tesla, this was something I was dealing with myself. I dont even know if I would be happy with that (I actually probably wouldnt be happy with that) but at a MINIMUM that would be my expectation, because anything else would absolutely impact my ability to sell the vehicle later. Any savvy buyer is going to want to look at simple things like labels on battery matching whats depicted, to make "purchase or not purchase" decisions.
Whether the capacity matches previous or not is a bit immaterial to me to the root issue here of the part that was paid for not being the labeled part that was installed.
What the capacity is, etc is sort of a red herring to me on this, as all that can be debated but the part on the car does not match the part on the invoice... that seems to be very "open and shut" to me.
@tjv85 You asked for feedback and mine is that this seems very clear to me that Tesla did not meet their obligation to install what the invoice says they installed, and at a minimum the label needs to be corrected, by them, and they need to give you something in writing stating that the battery that is on the car is the part number you paid for (perhaps some technical printout from their systems showing the reported information from the vehicle from their system.
Failing that, I would (politely but firmly) state that the labeled part number is not the one that is installed, and how can I get this corrected?
I am not a lawyer though, so I dont know where you can go with it, but I am wishing you the best in getting this resolved appropriately.
