2004 Subaru Forester XT with a bad turbo?

I have a Subaru Forester 2004 with a turbo. The turbo has blown three times. First time was around 50k miles, second one at 51k miles and now the third at 54k miles. Have done oil changes every 3k miles with documentation. First time Subaru paid only because we had our oil change docs which is what they immediately blame it on. Second time they paid half saying that they couldn’t verify that Jiffy Lube used the right oil if you can believe it and the third time well they are thinking about it. The car has serious design issues. Subaru can’t fix it (they’ve replaced each turbo and have done a complete tear down to try and locate the problem) and they know it but they will not admit it and keep fighting us all the way. Time to trade it in after it’s fixed. Will it be another Subaru? No way. I have a Tribeca that has had no major problems but that’s going to go as well in time for another brand.
