Starter problems of the 2008 Volvo XC90

2008 Volvo Xc90 v8 has been towed 3x in the past month. The battery has completely and inconsistently drained. They checked relay switches, fuses, alternator, starter, battery connections, etc. 3x in the shop! so fed up. Car is now in shop and I've read that Volvo is in a class action lawsuit for battery drain from sirius radio even if you do not have the subscription. They are charging me $135 to diagnose at Volvo right now. It hasn't been diagnosed as that is the problem yet, but the service manager is inclined to think that's what it is. Clearly they are aware of the problem. Also got stuck completely in drivers side seat belt and then it wouldn't work at all. Having door opening problems on driver side door and I'm just super frustrated. This has affected my business and seeing customers, etc.

10/30/2013. . . Failed ignition lock switch at 31769 miles, in garage, no warning resulting in having to have vehicle towed to dealership, part investigated ordered and ultimately replaced at a cost of over 600$ as well as the cost of a rental vehicle for a week because part needed to be ordered and shipped to dealer. Additional rental cost at just over 200$. Followed by starter switch behind the ignition lock switch failing on 4/08/2014 diagnosed at dealership, part needing to be ordered and then installed 4/22/2014. A cost of 165$, mileage at this replacement was 34332. After which I contacted the Volvo customer care department and sent all required information to see if there had been any recalls on this vehicle/ part. I was informed it was not a recall item. They also said that on a vehicle that age an mileage I should expect some maintenance issues. I keep my vehicle maintained and checked on a regular basis. Having spoken to the tow truck driver and an vehicle mechanic that has 2 Volvos they both said they have personally had this same issue with the ignition lock switch, once when driving. Volvo offered to reimburse me up to 30% of cost of part/s up to 200$. I needed to send in documentation and copies of work completed. My concern is that in light of the ignition issues with gm that have been ongoing for 5 years. . . Is this the same thing just not identified as of yet and if the Volvo corporation does reimburse a portion of my output to fix the ignition create the environment that will lead them to not allow any rights to owners if this becomes a recall/ legal issue?.
