So my 2017 F-150 appears to have the wonderful cold start rattle. I been reading as much as I can on the forum, but have a quick question for all the experts out there. We are leaving on a two week, 2500 mile trip in less than two weeks towing our travel trailer. I don’t want to be left stranded with the family! I had it at the dealer two days ago for the 25k service. I showed the service writer (who says he used to work in the shop) the video and he agreed the noise was not normal and needs to be addressed. He told me not to worry about it and bring it in after our trip as they are booked out at least two weeks for this type of service. The noise goes away and all seems well once the truck is running. Thoughts? Not sure if my video attachment worked or not...

 

Ouch! Which engine ?

 

3.5 Eco. Doesn’t sound that bad every cold start but happened to capture that one. Just did it this morning and it was barely noticeable.
