08-12 escape transmission reliability? Is it really?

So I hear everyone say the 08-12 escapes are super reliable but I hear the 6F35 trans is not. I’d love to get a used escape but the complaints about the 6F35 have me concerned. Are these complaints for 2013+ escapes? What year escapes should I be looking for if I want the most reliability? Is the 3.0 motor more reliable?
