CX-9 transfer case failure

I have been told my 2009 Mazda CX-9 Luxury needs a transfer case and now a new transmission. The transfer case is going to cost $3500, but out of "good will" Mazda will pay for the transmission, but I still have to pay $500 for the installation. The way this issue has been presented to me, and the reading I have done, it sounds like this is not the first time this has occurred. Have you heard of this?

There have been reports of transfer case failure in the CX-9, due to poor lubrication as a result of the oil deteriorating over time. In the USA Mazda increased the warranty to cover the cost of repairs to the transfer case for vehicles produced between 2009 and 2013. The company said it was a result of driving under high load, like towing, or on low-grip surfaces, which caused increased oil temperature. The warranty coverage was increased to nine years. The deal you have been offered isn't a bad one, for $500 you're getting a new transmission, but if you want to take it further you'll need to negotiate with Mazda directly.
