Toyota's So-Called Warranty: A Costly Surprise for My 2017 Corolla

I'm the proud owner of a 2017 Corolla, and I've always diligently maintained and replaced parts, such as brake pads and wipers, through authorized services. My Corolla is still covered by Toyota's 10-year warranty, but the tire pressure sensor recently failed. When I took it to the service center, they informed me that the sensor was not covered by the warranty and that I would have to pay a whopping 2700 TL for a replacement. How is it possible that an electronic sensor is not covered by warranty? This is not the dependability I expected from Toyota. I'm hoping to resolve this complaint and figure out why an important part like the tire pressure sensor isn't covered by the warranty.
