2006 Porsche Boxster S Question: Tiptronic will not downshift and car jerks.



Visitor, Anchorage, AK, June 25, 2011, 13:55

When trying to pass at 65 Mph, the car would not downshift or accelrate. It operates fine with slow acceleration. Also, the left window will not return to up position after top is raised.
