What kind of powertrain issues are people seeing after 50k miles with the V6? I bought my 2013 Crew V6 brand new in June 2013 and have put 25k miles on it. I assume I'll hit 100k after 4.5yrs or so of ownership. At that point, I'll get rid of it, but wanted to know what issues to watch for between 50k and 100k miles. So far, I've had a couple issues with the transmission: software update for reluctant upshifts and most recently a "clunk" on throttle reapplication after coasting which was allegedly fixed by replacing the driveshaft last week (the clunk remains). What else should I keep an eye out for? Thanks.
