2001 Subaru Outback Limited AWD 4dr Sedan (2.5L 4cyl 4A)
I was totally "snowed" by Subaru and others who have owned Subaru's. "Oh, they're so reliable I have 2 of them". "They're bullet-proof". So I bought a new 2001 Outback sedan for the "reliability" and the AWD for snowy weather. At just over 50,000 miles, one head gasket blew and while testing the system, they found the second one ready to go and had to replace it too. The repairman told me I wouldn't have the problem again when I told him I would not buy another if this was going to be a problem every 50,000 miles. Now at 120,000 miles, the head gaskets have once again gone out. This will be the third set of gaskets for something "bullet-proof" and "extremely reliable".
Go back to the drawing board AFTER you look up the true meanings of "bullet-proof" and "reliable". Apparently you've changed something or forgotten something vital risking the loss of customers...me for one.
