Gear damage Verso D Cat

Hello together, must admit, I’m a little disappointed. Buy me a Toyota because this should be very reliable. just after an odysse with Opel not a bad consideration. But after 20,000 !!! km a transmission damage was diagnosed. Ok can come to every car brand, will certainly not change the brand, because I am in total very satisfied with my dare. But that can not be normal. Have you had similar experiences? Everything started with a sc Hinting noise, which disappeared with the clutch, and increased with a clear bearing noise in idle.
