Side/window Air Bag problems of the 2010 Lexus IS350

Takata recall passenger side airbag was recalled July 2016. We were told it would be repaired no later than Feb 2017. Now we are being told June or July 2017. I have a loaner however I have been making a car payment for a Lexus and I have a chevy impala loaner. I can't sell the Lexus I am stuck and furious. What recourse do I have? I paid for extended warranty when I purchased and car isn't even being driven. At what point does Lexus have to compensate me for my out of pocket? at what point do they have to buy the car I can't drive?.
