A few questions for you. Year, and is this still under warranty? And the Dealer says...? Has it been running really rough? I'm not a mechanic, just a concerned party

It's a 2012.. pristine condition, all maintenance done at Porsche according to their guideline. No symptoms at all.

Porsche reps heading to the dealership to figure out what happen.

With all those reords for them to gander at, the dealership should make it right. I'm a little curious as to what the service dept has to say...or if they find the same things. Let us know what they find out.

A new engine is needed/replaced. Porsche is stepping up to the plate and will be replacing the engine 36k USD.

D'oh! That's good that the are stepping up. Although, I am a little bit confused as to why you had this (major) problem in the first place.

I keep asking that question and it seems like the best kept secret. I am pushing for the answer.
