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.
Tl* the contact owns a 2011 porsche cayenne. while driving various speeds, the contact depressed the accelerator pedal and the vehicle started to jerk. there were no warning indicators illuminated. the vehicle was not taken to a dealer to be diagnosed or repaired. the manufacturer was not notified of the failure. the failure mileage was approximately 80,000.
The transfer case in this car is failing at 50,000 miles leading to potential lock up of wheels, axles, or total breakdown/shutdown at highway speed if not corrected. there are numerous known owners experiencing the same issue.
Transfer case went bad at 64k miles. three tsb's on transfer case problems including the very issue my car has.
The transfer case clunks and grinds when driving turning and in reverse with only 60,000 miles on the car and the dealer said it needs to be replaced, from what i have read this is a wide spread problem
