I have a 2016 Lincoln AWD 3.7L V6 I took my car in for preventative maintenance of the PTU. Normally it should be changed at 30k miles. Let's first back up to jul y 2019 when they replace the shaft seal then fast forward to July 2020 and only drove the car 1600 miles in 1 year. 31,159 miles and the PTU IS JUNK recommended NOT TO DRIVE it until the part came in and coukd be replaced. Mind you this car had 25k miles on it when I bought it. It's a CERTIFIED PRE-OWNED LINCOLN it came with a drive train warranty ending in January 2022 or get this originally 100,000 miles they decreased the miles by 30k now 70k miles. I know I'd never hit the miles but come on man. Changing the miles after I bought it? I have no idea if I can extend the power train past 2022 until they decide to send a letter IF AND ONLY IF THEY STILL OFFER IT. What a crock!!! Ive been changing my engine oil once it hits 50% just in case it will save that water pump. They claim the water pump was fixed for my model year but how can i believe them when the PTU fails at 31k miles I hope the new one comes with a drain plug the factory one did not because in 2016 it was still a lifetime oil
