That being said, Tesla went back to early Ford for the full top-down flow system - and it's working for them. So while I love the TPS system and use it in my company, I'm willing to keep on learning.
Reliability was always a selling point for Porsches relative to their competitor. You could buy a 308 and be constantly fixing it, or a 911 and (so long as you didn't put it in a ditch) you'd have an everyday driver.
The fact that it's dropping suggests that they're feeling the effects of VW's ownership, crapping their designs up.
There's a lot of weaknesses that show up a lot quicker when you're holding an engine at redline.
They share some functions like brake SW or ACC, but they do their own engine and chassis.
Otherwise they source their stuff alone, and due to the low sales number they struggle to find willing suppliers.

As a personal anecdote: my 2003 VW (1.8T GTI) had 330,000km when I sold it to a friend (it continues to run strong, but not sure the KMs). I did all the work myself and I did it on time. Biggest repair was AC Compressor, the rest was just routine maintenance and a couple $50 sensors. If a CEL came on I addressed it as soon as possible. At the same time, I had a friend with a similar year Jetta TDI which lit on fire around the 290k mark. Every time I was in her car the CEL was on, and I remember driving it home on a road trip once where you'd hold the pedal to the floor the whole way just to keep it at the highway speed limit.
Down to 9/26 from last years 4/26. Compared to VW's 24/26 that's quite a large delta.
TBH some of ranking on the list makes anecdotal sense (Toyota is #2). Others do not (Mazda as #1?!).
I'm questioning Consumer Reports methodology, how far back do they look? If it's only a sliding window of <3yrs I do not believe thats enough data.
I always chalked up reliability as a function of new tech introduction + focus on reliability. I figured Porsche gets decent numbers because of how relatively low-tech they are and the ridiculous prices they charge for optioning-in that tech (basic things like ACC or memory seats).
Is there something else organizationally, process or product wise that Porsche does differently than the VW group? I do know that they have a separate factory w/ seperate engineering departments (:cough VW engineers design Lamborghini's).
