First of all, Hello to everyone here. Got my new 2014 FX4 supercrew about a month ago. I have to say that I really like the truck and so far have little to complain about even with the poor gas mileage. I was wondering if anybody has experienced a low growling noise that almost sounds like the rear tires are spinning under light acceleration from a rolling start. I know it's not the tires because I've spun them a few times since new just for the hell of it. It sounds like it's coming from engine bay and only intermittently. I was wondering is these motors make some different noises that I'm not familiar with or if something's wrong. Second, anyone have a little rattle coming from the drivers b pillar? Almost sounds like the weather strip is still pretty tacky and is making noise. Was wondering if the door latch can be a adjusted a hair to shut it up. Thanks for any help. Great site, lots of good information.
