I just got a text to set up a new pick up time for my car, so I'm not as salty as I was when I first set out to make this post. Still, I think it might be some good information to arm yourself with if you ever find yourself in the "in spec" predicament.
I keep reading about some of your experiences with the SC telling you a misaligned light strip, or any other messed up cosmetic item is "in spec" and it really gets in my craw. For context, I'm a Manufacturing Engineer for a very large production company, so I speak Engineering-ese, and I'm here to tell you that's as BS an answer as can be.
Before I get into this, let me just clarify that I don't know any of Tesla's specific policies, so what I am going to say is in the context of general manufacturing and engineering processes for a consumer-level product.
The term "In spec" likely refers to the margin of error that exists in the engineering specifications. Generally, for a product to be acceptable, it has to match the 3 F's-- Fit, Form, and Function. It should fit correctly in the configuration that it is installed, the form should follow whatever engineering guidelines are established, and of course it needs to work, or function. For structural components, there can be some variance in the first two, Fit & form, as long as it functions within engineering design specifications. However, when you're talking about a cosmetic item like the light strip, all three F's have equal weight. If it doesn't fit and follow the form of it's installation position, it falls short of the aesthetic expectations a customer will have, regardless of whether or not it actually functions.
So when you tell the SC that your light strip is misaligned and they say it is "in spec", your reply should be that it does not meet your expectations for cosmetic appearance and aesthetics and as such is defective. Stand your ground and be the ultimate Manager-contacting Karen if you have to. It doesn't matter if it meets engineering specs. If it's a cosmetic item and it's ugly, it's unacceptable. Period.
