Last week got the PTU issue fixed
went in at 8:30 and they had 2014 MKZ loaner car ready for me. Got a call at 4:30 saying my car was ready.
I asked what they just replaced the seal and they said they replaced the whole PTU unit. Hopefully this means even better reliability
When I first drove the car it felt a bit rough, but maybe that's because the whole day I was driving the 2014 2.0 AWD which is ultra smooth and just as good as the 2010-2012 3.6 V6 with power and acceleration.
Overall I hope this fixes the problem. I have had the car for about a week and no leaks or smells yet.
