Just one example. If you google gt86 engine failure you will see how bad it is. Its the only reason i didnt get the gt86.
Toyota screwed up with a subaru engine. Shame really gt86 was ideal car for them to have dropped in a 4age revving to 11k. Lol
I just tried googling that, and came up with a few examples, but not an extraordinary amount.
Now try Googling "golf gti engine failure". I don't have the time to scrutinise every result, but a quick scan seems to show just as many results for that, as for GT86 engine failures. In my experience, the amount of owners with no problems far outstrips the amount of failures - which is what I'd expect with any mainstream car, really.
I've also talked about the engine with the guy who I use to service/tune mine, when the discussion turned to power, and he was of the opinion that despite the criticisms about it's output, the engine was a solid and reliable unit - and given his experience with them (which is extensive, including FI modification and tuning), I'd trust his opinion.
I don't doubt that there have been some engine issues, but to seize on that and claim that there's some sort of inherent reliability issue seems a bit of an exaggeration, especially given the overwhelming majority of owners who haven't reported problems. I've certainly never been aware of any widespread concerns, despite being active in 2 prominent communities (precisely so I can stay abreast of any problems to look out for). I would suggest that if you actively go and search for reports of engine failures on
any car, you would probably come up with multiple results, but to use that as a reason to write the car off entirely seems a bit overcautious.
