Side/window Air Bag problems of the 2015 Mercedes Benz GLK350

I recently purchased my 2015 Glk350. When I purchased it there was an open recall for the passenger side airbag. I contacted the local mercedes dealer to have the airbag replaced and they say there is no solution for the issue. So I am driving around with the airbag turned off(by the dealer) and the dealer can't tell me when or if this will be replaced.

Front driver side airbag malfunction.

Takata recall - mercedes I've just received a letter stating my 2015 mercedes glk 350 has or may have a faulty passenger side airbag or inflater related to takata's poor quality standard. I checked with mercedes and they don't foresee replacement parts being available until may 2020, which is wholly unacceptable in scope. I understand this recall has been initiated voluntarily due to takata's history and there have not been any mercedes incidents, however if the part is concerning enough for a recall I am extremely dissatisfied that it could take over a year to remedy it and I could be potentially putting myself or family at risk. I understand the scope of this issue is global and of a new scale, but that does not absolve mbusa of providing an expedient solution; also it seems all manufacturers have been affected by this over multiple years-- why has there been such poor supply chain accountability and why have all brands been using only the same manufacturer for critical life safety? there needs to be more stringent observation of this in the future. Furthermore, this is a 2015 vehicle, and mercedes informed me via the phone that an investigation was instituted in 2016 but nothing was borne of it; I am confused about how now in 2019 we are reaching the point of recall without an incident, and also since I have purchased the vehicle after 2016 why there was no mention at all of this being a possible issue. Unacceptable that manufacturers have been able to skate on this issue.
