i got a use 04 about 2 month ago, and the rear bumber startet to crak on the passinger side, right under the tail light cuoner. has any body had this problem, will warranty cover it and no i have not hit something, and i have not been hit by anything, i park in reves, leving the front end facing out all the time.

 

Sounds like the previous owner had a rear end boo-boo.
If the bumper gets damaged, Mazda insists that the bumper cover (which includes the bottom center insert) is irreparable needs to be replaced. Costs about 750.00.

 

no, i use the nav sistem to visit the previous owner, to see why she did not want the car anymore, and she toll me that she love the car but, she needs more room, so she tried it in for a infinity suv, so no rear end boo boo, and the rear end is perfect, the paint, the alement, the lines, not one screach of bein hit from the back, but the day that i saw it some one thuoght food on the hood, so am thinking that some one that lives here, kick my bumber and thuoght the food on the hood, basters.

 

In that case, I agree with you.
Someone may have bumped or kicked it.
There have been some hateful attacks on our cars...
