At about 24,000 miles I began to hear this same rattling noise everyone here is describing at the drivers side rear of the car and although I continually asked the dealership to check the car to find the problem, a problem was never found. I thought it might have been the exhaust bouncing around after being told there was no problem because the car still rode well. 4 years of this noise and 4 years of complaining about this noise and the dealership has finally, finally found that the coil spring on the drivers side rear is broken! I have been driving around like this for 4 years! Even the service manager said a broken coil spring is rare on a car - they better do this work under the warranty, even though it's now expired!
Great car other than this persistent rattle from the passenger side rear of car on bumpy roads. On the highway there is no problem. This web site is very helpful.

I've had my car in to the dealer three times and they still cannot diagnose the problem. I've replaced undercarriage cowlings (front and sides) and front struts but the binding, rattling sound is still there. Listened to Car Talk and when a listener described their problem, it was diagnosed as stabilizer links - which very accurately describes my problem. Why is it so hard for the dealer to find?

Clunking noise coming from passenger side rear. Usually occurs when I am on a bumpy road or going over railroad tracks. Husband looked under car and the swaybar link is bent and nut is rusted so you cannot tighten it. Going to dealership to have it looked at this weekend. This really should be a recall item!!!

My wife noticed a rattling noise from the rear of the car. The noise was more evident as we drove on rough roads and hit pot holes. It sounded as if something was rolling around in the trunk. I looked at the shocks and saw nothing wrong. The trunk was empty and no parts were visibly loose. We took it to the Dealership very frustrated since we have had no issues with this car since bought new in 2007. The Dealership told us it was a stabilizer bar link. I had never heard of or seen such a part. They replaced it. Here we are 2 yrs later now with 73,000 miles and the stablilizer bar link is broken again. This is very frustrating. What can we do to not have this problem continuously, other than sell our car?
Sounds like the front and rear to on my Mazda 3!

I'm also noticing a rattle noise from the rear of my car when doing lower speeds or going over speed bumps.
