Car rattles and shakes significantly (especially the rear wheels) during acceleration. Took the car to dealer informed me that it is the 'transfer box' that has failed and it is a known problem with this car. The issue is so common that Porsche does not have parts available and they are on back order. The wait for the parts to arrive could be in months. This should be a recall.
