Mazda Canada said I can try dealership and plead case. Dealership is sympathetic, and tried to qualify for goodwill, but no luck. I guess my last play is to plead my case one last time with Mazda, and if they tell me to F off, then I blast it on social media, JD Power surveys I still have to do, reconsider new car purchases, etc.
Part number for cluster is TD7H-55-430. $$3483.32 at dealership, haha, oof. There seems to be lots of eBay units kicking around, but not sure what would happen if you swapped. Is the odometer tied to the cluster anymore? Or is it fed from the ECU? I wonder if the cluster could be disassembled and the LCD replaced?
Likely just have to get used to looking at it. Unfortunate, but doesn't really affect anything. It's just such a visable defect. Every single time you start the car, you see it. Kick in the pants when it's just barely out of warranty.
