Kept hearing a rattling noise coming from rear driver's side, took the car in two times B/C of this. Turned out to be a problem with the rear seat rubber bushing which is requiring the dealer to grind the arch weld on the spring coil. There is a service bulletin about this very problem, which indicated that they have redesigned the parts in newer models so this does not happen. I feel that this is a design problem for which I have to pay for the repair and that it is not due to normal wear and tear on the car. It seems to me that they should fix the parts due to their faulty manufacturing/design?

Loud clunking noise in left/front over uneven surface. Worse during cold weather. Checked by independent dealer then by Mazda dealership. Told sway bar bushings were the problem. Car was under warranty at time of initial complaint, but technician was unable to hear it. [bushing warm by the time I got to dealer]. claim made to Mazda to repair under warranty but was declined. Internet search shows this to be a known problem on this model.

I purchased a used 2009 Mazda5 knowing that it needed tires. After buying new tires I had the car aligned. I was told the alignment was "within spec" despite the fact that the rear camber was set in such a manner that the tires shop said I'd be lucky to get 15,000 miles out of my new tires. I was also informed that there was no adjustment for rear camber without buying a $600 camber kit. I took it to the dealer, assuming they had more experience with the car, but was told the same thing. In order to properly align the car I would have to buy an aftermarket kit. I believe this is a safety issue because with the extreme and unadjustable negative camber tires can wear down to the cord on the inside edge while looking nearly new on the outer edge. All this happens rather quickly while the car is technically within the rather wide specification set by Mazda. Mazda customer service denies any knowledge about this problem despite hundreds, if not thousands of people claiming to have brought it to their attention. Mazda knows this is a dangerous problem, but ignores the issue.

Left rear shock failed at 21222 miles on March 23, 2012, covered by warranty. Right rear shocked failed at 28073 miles on October 20, 2012. Mazda refused to replace right rear shock on March 23, 2012 due to no visible failure at this time. Mazda would not replace right rear shock unless I paid for it on September 20, 2012 due to lapse of warranty. These shocks have shown a history of failure at low mileage and Mazda should be forced to recall these shocks due to their potential to cause loss of vehicle control.

Rear shocks fail at 40K miles. Have the shocks replaced at the dealer, making the same noise at 50K miles. I think the quality of shocks and suspension for this car is poor.

Auto has had to have complete set of tires because of premature wearing on outer edge of tires after only 32,000 miles. New tires are already showing signs of premature wearing even though they are being aligned and rotated regularly at only 52,000 miles.

This van has 67,000 miles on it and I've had to replace the tires two times. I have flats going down the road. The inside of the tire is eat away. We have had the tires balanced and aligned to no avail and complained to Mazda. Looking at forums on the web, there seems to be many issues with this happening.

Intermittent car shaking. After driving for a while, at speeds of around 60 or above, the car violently shakes, especially on bumpy roads. This is an intermittent problem. The dealer (faulkner - philadelphia, pa) - recently did an alignment and fixed a tire rim. The issue went away for a while, but occurs once in a while now. I am not sure exactly what part it is. Note: About a year ago, I hit a curb which had debris on it which ruined two tires. All 4 tires did end up on the curb, and I did replace one of the tires and had the other one plugged and got an alignment.
