Yes, enough problems on ours that Porsche finally bought it back. Everything that could go wrong did ... electronics; top replaced; peeling paint; lug nuts; new engine etc etc etc... at one point it sat at the dealership for almost 6 weeks.
But Porsche was fair, they supplied loaner car (not a Porsche), valeted car back and forth etc. The beastie was just a Lemon ... those things happen. Would we buy from Porsche again ... yes.... just not a first year model.
