I'm getting the creaking/popping noise while turning into my driveway, or backing out from it. It has a very slight lip, compared to the street. I always back-out/enter very slowly, but the creak/pop persists, since new. Now has 5K miles, problem not getting any better.
It also creaks/pops while turning from stops, either left or right turns, slightly bumpy road surface.
I also have two internal (cabin) issues that are really pissing me off; something is resonating under the dash at exactly 1500 RPM, on cold start. It disappears when the engine has warmed-up. The other issue is the passenger side upper seat belt pillar mount (which is vertically adjustable) rattling intermittently.
I bought a new Focus SE in '09, which I turned-in at a loss, because of major drivetrain/brake issues, and now my new '10 is having issues albeit different than the '09.
I'm done with with U.S. Focus. No more for me. YMMV. Good luck.
2012 Focus; Maybe 3rd Time's the Charm?
