Mokka, power steering total failure while driving, rear window suddenly bursts with loud bang

New Opel Mokka 1.4 eco flexNUR PROBLEME New purchase in July 2015 a.) already in January 2016 Total failure of the power steering during the ride, is probably “only” a software error/problem, but you have to experience during the full ride, how nice this software problem then feels, especially in the corner area, especially in a curve b.) now we sit yesterday afternoon on the terrace, vehicle parked opposite on the road (village, 30 zone, no human far and wide, gess We don’t think it’s going to happen either), suddenly there’s a loud bang and the rear window is bursting and torn into a thousand pieces. After opening the rear door, it’s decaying into countless parts. (Luckily, I documented this immediately in my mind before touching anything) (see pictures as an installation). Who in the forum has had similar experiences and can report about it? Let’s wait and see what answers Opel has here with a 9-month-old vehicle and what argument e presented here. I have now completely full the nose of Opel-Mokka, my previous Mazda has served me 17 years without any problems. I am grateful for information, what others have already been able to experience here – and if necessary technical information, how anything is possible ! Thank you very much lpa209
