Thanks. An eye-opener for me, as well. I sent Nikon USA my well-cared for lens with noisy AF (?possible early AF motor failure) and authorized payment of $800+ for repair. More than 2 months later, I discovered secondhand (notified of billing through my credit card company) that my service order status was updated from "Parts hold" to "Product replaced". I contacted Nikon Support who initially told me the lens was "beyond repair" and that they were shipping me a refurbished lens (confirming that "Product replaced" status means swapping original for a refurbished lens, not replacement of AF motor or other part for repair).Question from someone who doesn’t understand: you sent Nikon your property and they kept it? Where I come from that’s theft.
I contacted Nikon Support again and pressed them for more details. They confirmed that, actually, this was a supply chain issue and that they could not allocate the new part for repair in a certain (i.e., *their*) timeframe, so they would be swapping out my original lens (with original like-new trunk) for a refurbished lens (and a broken, heavily used trunk, as it turns out). Nikon Support presented this as their sole remedy and never offered other options, either proactively or in our back and forth emails.
In hindsight, I should have been more hard-nosed about the situation, although by that point my credit card had already been billed. Another lesson learned. Dealing with the aftermath now after checking in with Steve and the BCG Forums community. Still waiting to hear back from Nikon Support. I do think big corporations need to be held more accountable for shabby practices (just as they should be richly rewarded for excellent products and services they do provide), and I am hopeful Nikon will eventually make this right. I greatly appreciate the supportive comments and advice here, and I hope sharing my story might be helpful to others.
