| Vehicle Speed Control problems |
Purchased a 2013 Cayenne Porsche gts with 67k miles on it. Noticed a kind of thumping sound when accelerating, usually appearing at 3k rpms. Vehicle shudders and almost feels like the transmission is slipping. Took the vehicle to a mechanic to diagnose the fault and they immediately knew what it was, engine transfer case failure. This is due to a design flaw allowing water into the transfer case that Porsche is aware of and yet to address. On some occasions Porsche will pay for the $5k repair but the part is still replaced with a transfer case with the same flaw. Transfer case failure can lead to a sudden lose of power and potentially cause death or serious injury if someone is traveling at highway speeds. Highly recommend addressing this with a recall for 2013 and 2014 Cayennes. I have experienced sudden lose of power due to transfer case failure, neatly resulting in a highway collision.
