Started to hear the rattle around 1800 miles. When I would drive over roads coasting, something in the front left of the car would rattle. I took the car down to Mazda to figure out what it was. I dropped the car off. They called me the next day and said they couldn't hear anything. The asked me to come down because I insisted the noise was there. I drove along with a tech and sure enough it took a few miles but this it was very apparent and you could actually feel the vibrations in your feet.

So on the 3rd day, they said it was a strut top. It was going to take 10 days to ship but that happen to find one at another dealership.

I made a mistake buying another Mazda. My 2010 Mazda had little and bigger issues that had be in and out of Mazda constantly. We all know how much of a hassle it is to take time out of your day to have a defective car fixed. (if you own a Mazda)

Update from Sep 4, 2015: I was in a hurry when I typed out the last details. Apologies for the broken English. So, long story short:

1. Noise in suspension 2. Techs could not hear/find an issue 3. I make another trip to point it out. 4. Rattle/Noise confirmed 5. Mazda replaced suspension mount. 6. Send me home with car. 7. Noise still exists/nothing has changed 8. They stated they FOUND a problem and fixed it. Seems like they found a SEPARATE problem unrelated to the rattle/noise 9. Brought the car back 10. Replaced ENTIRE drivers side front strut. 11. Serveral visits/Hours in line/several rentals later. 12. Problem is fixed.
