I think my front pads are already worn at 24K miles. The low pad sensor scraping just started making noise last night. I called the dealership and ask them why the pads are already worn at 24K and they said it's my driving style. I think it's BS...I've owned 3 other Toyotas and this is the quickest pad wear I have ever had. All the other cars pad wear was around 45-50K miles.
