Look at the thread title. FF issues aren't the only concern with these engines when the warranty expires, and we have no data on how frequently these engines are having failures in modes unrelated to the FF.
I traded in my 991.1 GT3 because I had generally lost confidence in the G6 engine. I wasn't going to assume that non-FF failures are rare with the G6 after I had experienced such a failure at low miles in my own car. Lack of reported failures in this thread could be due to this thread having too small a sample of owners to capture what's happening in the population of these cars, or cars with the G6 engines are hardly being driven, etc.

I understand your logic, but you're not seeing my logic.

Sharing incomplete information may as well be sharing bad information.
All it takes is one casual browser to spread that G6's suffer the same fate because they read about it on Rennlist and are now spewing it on FB groups, youtube or something similar. And now you're effectively messing with people's wallets.

Looks like my car was not alone:

The other thing is the failure happened early in the car's life, which the industry term for that is called infant mortality. The statistical failure rate for any system tends to follow a curve on a graph that looks like a smile. The likelihood of a failure is highest at the beginning of life, then statistically drops rather soon. As the system approaches its end of its design life the probability of a failure increases again.
This is why we have warranties. I would venture that your case was simply an outlier due to a non-conforming part since it happened early in the car's life and to the best of our knowledge no one else has reported this failure before (or at least very few have). I understand your frustration, but I wouldn't let that incident dent your confidence.

Well, as you said, you don't know how many G6 engines have failed in other ways. So, I would challenge your logic because you can't really say much about any possible trend with a sample size of only one datapoint.

Many people won't get to 5-15k miles even within the 4-year warranty period. Only a minority of owners drive the cars enough, and hard enough, to really test their reliability and durability within the warranty period. Porsche knows that, and it surely went into their calculations when offering the 10-year engine warranty. But the replacement engines don't carry a long warranty - I believe it's only 2 years - even if the replacement wasn't done under warranty. I believe that owning a G6 engine out of warranty is a risky proposition, and I chose not to do it. PDK failing at about 42k miles, and needing complete replacement for $19k out of warranty, helped me make that decision.
For that very reason I purchased the VSP Platinum extended warranty; however, looking at how long it took for my E-series motor to eat itself (6yrs) I doubt (even with very heavy use) the G6 will let go in same amount (or less) of time especially with improved oiling, etc.
If the PDK lets go it's covered under warranty, but after recently hearing a close friend's third party Porsche VSP warranty experience, I am hard pressed to think things will really be as simple to implement warranty coverage.
He was denied a front alignment and a $28 tube of some grease after C4S front CV boot replacement ($3.5k) under the VSP third-party claim. Yes, that's chump change in the Porsche repair world, but to nit-pick over such incidentals is ridiculous IMO.

I loved the car, and traded it in only because of the warranty expiring. If there was a reliable fix or good extended warranty for the engine (and transmission) concerns, I would consider buying another 991.1 GT3. With a good alignment, the car wasn't much slower on track than my 992 GT3, which costs twice as much.
