I'm getting a little mad reading all this negative BS; it's my 4th porsche (965/993/996/997S) and ihad respectively 90k/93k/99k and now 18k on the teller and did never had a problem (except RMS on the 996). I'm a very "enthusiast" driver (cfr 997S uses 15.9 liter /100km)though.
I'm sure i can break a p engine in no time by driving to the red-zone with a cold engine...but drive the car softly 3500rev when cold for app 9km (6miles) and i thinck you're on the way for a troublefree engine then.
Same story for my early alfaromeo's, they also had lots of oil to warm up... but once good heated you could go as far and as long as you would...
I find it kind of amusing that you think one RMS failure is acceptable. A Porsche is supposed be able to take a beating. Yes, you should warm it up, but a modern car should not fail.
I also find it amusing that lots of people here think its a minimal problem, does not happen much, etc, etc, so how does this work, you pay 100K, and its a roll of the dice if your engine will fail after some unknown number of miles. Sure makes for enjoyable ownership, wondering when and if the motor will fail. This is not negative or internet gossip, its a fact, my C2S has had no issues yet,
but will the motor fail
I think everyone needs to put the engine failure problems into perspective.
I don't have data for the 2006 calendar year, but for 2005, Porsche sold approximately 18,000 911's and Boxsters in the United States, which may have accounted for at least 1/3 of their total sales, more likely about 35%. Porsche - based upon the 2004/2005 annual report, which doesn't cover the start of the 2006 model year production - produced about 48,000 911's and Boxsters in that model year. Because of the success of the 911, bump that up to about 50,000 total for the full 2005 calendar year.
Perfect quality in manufacturing is usually denoted as six sigma quality by managers and engineers, which means about 3.4 defects per million units (any engineer or production type managers please correct me if I'm wrong). That kind of quality is achievable for extremely large production volumes, not for a small volume producer like Porsche.
But suppose that even 5% of the boxer-engined cars have bad engines. That would mean, in each model year, that 2,500 cars would have bad engines. That's an extremely high number. If, as some have said, that a replacement engine goes for about $12,000 (which I doubt - I had a 1992 Ford Taurus SHO with the Yamaha double-overhead cam V-6, and that cost $14,000 for a replacement in the 1990's). What we are talking about is U.S. dollars 30 million per year in replacement costs. This level of defects would take a real chunk out of Porsche's profits, and it would pay them to improve quality rather quickly. To me, such a high rate of estimate defects is just not believable. Even a 2% defect rate on the engines (1,000 failures per year on that specific model year would cost them $12 million a year, just for those new models. If you add in the warranty costs for previous years (in the U.S., the warranty is for four years), Porsche would have astronomical engine warranty costs.
My point in all this is that the economics of engine failures dictate that Porsche reduce the failure rate drastically, and I believe they have done just that, if they have needed to. Otherwise, they'd be facing bankruptcy instead of making record profits and getting the number one quality award for initial owner satisfaction (the first 90 days of ownership) from J.D. Power in the U.S.
Yes, there are some engine failures, as with any car manufacturer. And for those Rennteamers who have had problems, I can sympathize with you.
But Porsche's actual numbers have to be quite low. Complaints on web sites seem to get magnified into catastrophically large numbers, when in fact they are relatively small. Making a swag (scientific, wild-*ssed guess), I would venture that at most only 0.2 - 0.4 percent of the engines have problems (namely 100 - 200 engines per year, at most). Frankly, that's darned outstanding quality for such a small producer, and its more believeable than some of the wild claims made by some others.
