| Description of the problem | I was pulling forward on a level city street and turning left from a stop sign. There was a significant amount of shuddering and feeling of a loss of power. This was a significant safety issue due to oncoming traffic. Over a period of several months this had been increasing in severity but the dealer could not identify the problem. I took it to the dealer and was able to repeat the problem for them. They identified the transfer case as the issue. It was replaced. I also had to replace the tires due to the dealers identification that the transfer case had caused differential tread wear damage to a rear tire. As a former military aviator, there is no doubt in my mind that this is a safety issue. Porsche needs to identify what the issues are (design, manufacturing, servicing, etc) and remedy them. Surprisingly, this is a known problem because the service adviser informed me that they keep transfer cases in stock. They retail for $3944, plus the new vent kit (mine does not have it) and then add labor, and tires if they have been damaged. That is a lot of expensive inventory to have on hand if porsche wants to claim there is not a problem. |
