i had a fuel injector #3 crap out recently at 64k. skip was barely noticable. eventually the eng lite came on.changed plugs while we were in there. even compression on all cylinders and no metal in oil filter luckily. unfortunatly theres some random 3.6 that do have premature lifter and follower wear and entire cyl head assy needs too be changed. if your car is a 2015 it has the 5yr/100000mi powertrain warranty and should be covered.Was problem resolved? Really appreciate a response. Dealer has put us through the same process and now saying oil soinoild need to be changed...even though no codes thrown for it....and not cheap to have done.....and 6 hours of diagnosis.....
