Hi all, I purchased a new 14 MKZ 2.0 ecoboost last week and have put about 900 miles on to this point. I just returned from a long trip that was mostly highway.
TBH, the car does feel like it is "breaking in" a bit as it seemed a bit bouncy and tight the first week. Also, my first two tanks where around 22-23mpg (with lots of highway driving) and now my current tank seems to be getting 31/32 highway (again? breaking in?)
Anywho, the reason im here is: I noticed at almost exactly 80mph there seems to be a rattle/vibration from (what sounds like) the front or rear passenger side door (perhaps near the top of the windows).
With any vibration/rattle it is hard to narrow down, especially at speed. This happened enough for me to notice both going and coming on this trip. It seems be be almost exactly at 80mph and feel like it happens right after i stop accelerating. So perhaps im going 81/82 and coasting a bit lower when it happen. It doesnt seem to happen during acceleration which would seem to make more sense.
Car does have a moon roof (non-panoramic) but doesnt seem like the rattle is coming from that.
I have some VM from my dealer checking in on me and ill be sure to mention/ask when i talk to him, but wanted to see if anyone else had anything similar???
Something like this will be tough if not impossible for a dealer to troubleshoot as it would even be hard to replicate cruising @ ~80 anywhere near the dealer.
Thoughts? Thanks
