Mazda Mazda3 Problem Report
Mazda Mazda3 Rattle From Rear Suspension Due to Loose Stabilizer Bar Links
A Loose rear stabilizer bar link can cause a rattling noise from the rear suspension while driving on rough roads. Our technicians tell us if the rear stabilizer bar and links are not found to be loose, there are updated sway bar bushings available which should correct this problem.
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! - Visitor
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? - Visitor
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? - Visitor
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. - hondoman45
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!!! - Visitor

I've just heard this rattling noise at first I thought it was my spare tire. Ouncing around but I checked and nothing in the trunk was loose so I told my fiancé we are going to have to get it checked I just haven't had the time to yet - Visitor
I have rattling sounds coming from the rear of my 2005 Mazda 3 also. At first I thought it was the tag and tag holder, but after replacing the tag holder with a rubber cover made to prevent noise, it still made noise! It does get louder on bumpy roads and such, but mine makes the noise all the time and I hate it. - Visitor
Rattling in the rear on the driver side everytime I go over a bump. I had some one else drive it and I drove behind to take a look and the wheel bounces on the road everytime it hits a bump. I brought it in and the mechanic said it's the shocks but now I think it's the stabilizer link. - Visitor

I have had this issue for over a year.I brought it to the mechanic when I first hears it and they couldn't find anything. The noise is getting worse so Ibbrought it again and they are telling me it could be the transmission and the front axle? I thought for sure I kept hearing it from the back. Any recalls on this issue? - Visitor
I started hearing a rattling noise coming from the right rear of the car. I did some searching online and think that it is the right rear sway bar link, which I plan on replacing. Hopefully this will fix the problem. - Visitor
