I used to own a 2007 Mazda5. Sold it 2 years ago and now thinking of getting a new 2012. The only complain that I had is the loud noise from the rear wheels when I backed up the car from my driveway in the morning. It only happened in the winter (I live in Canada) and always went away after the car is warmed up. Some lubing helped but it always came back after a few weeks. My question is - is it still a problem for newer model years?
