XC 90 rear wheel blocked to the right

Hello, this week, after only 74,000 kilometers and just under four years now also with my XC90, the “hand brake coating waste problem” probably built in by the manufacturer came to bear. Wheel blocks at low speed – fortunately for me. So off to the friendly one. At the back right both coverings replaced – left side also a covering fell off or lay loose in the brake drum. This is not normal. And with the much-acclaimed safety of Volvo cars this has nothing to do with. With wear this is also not greenable for me. So slowly I really doubt about the quality of Volvo. Now I have almost all the errors already installed by the factory about me – wheel bearing 2x/angle gear 2x and many other small things. Since now this year would be due again a new car, I am really hard to think about, with the required quality and reliability of my current Volvo, whether it should become another vehicle of this manufacturer. I first wrote Volvo.
