Again based on what I have read, yes, they are that bad. Many are on their third transmissions. Apparently even Volvo themselves will not CPO a T6. That should tell you something.
I have not once read someone recommend buying a used T6 XC90, and this is on any of the 4-5 Volvo forums I used for research.
