In July 2017 I had a transfer case failure at 11,000mi. BMW replaced it under warranty.
A few weeks ago at 18,000mi I started to get similar symptoms (low speed driveline shudder) similar to my original problems. It was diagnosed as transfer case failure. Long story short the factory rep.came in and it was good willed under warranty. My previous Infiniti went 10 years without a problem.
I am concerned for the future of this transfer case.
