I have had the transfer case replaced in this vehicle twice in the last 25k miles. At 65k miles the car is doing the familiar grinding and surging again, evident it will need a third $5-6000 transfer case. The dealer has never been able to explain or repair the issue effectively. The manufacturer does not reply to inquiries, it is my request that they be forced to provide a permanent, reliable fix for this issue. I'm worried this could cause a safety issue under the right circumstance since it happens while the car is in motion. The mechanics at the various dealers have told me its a well known issue spanning Porsche suvs from 2008 through the present. Gotta wonder what this manufacturer is thinking here and why they are hiding the details.
