Yes it is. They have told all the dealers that they should replace them right away if someone report any kind of problem, specialy with batteries. This is third one I got from local dealer and it turn it self off completely when working on battery. Some of them after few hours but first one I had started that issue after two months! There is also two types of them on the market. First series had on the inside of the back door manual with lot of iphone setting pictures. That one is rly good. But the second one and the curent you will recognize with only four pictures on inner side of doors. Also no little hole for cable. It's bit lighter, cheeper plastic and sound is so plastic like theres no LBA at all. Simply not Bang.
I know there is ppl with working beolits but generaly its cheep problem. No time for extreme testings like before? In China? This problem is widely reported in four countryes atm. God damn it.
