Recently purchased a brand new Edge Sport. Got it home and over the course of a week, I was noticing red transmission fluid on my garage floor. Took it in last Friday and they confirmed that it was a bad PTU leaking. It only has 400 miles on it and I'm fairly upset that PTU failures are still an issue. What is the longevity of these PTU's after they have been replaced? Is this going to be an ongoing thing?
