If you own a 2009 Mazda3 with stability control, you may need to schedule some time at the local Mazda store for repairs. Mazda is recalling 7,100 2009 models for a problem with its Dynamic Stability Control system that the National Highway Traffic Safety Administration says is not in compliance with federal motor safety standards. NHTSA says the issue is that "the yaw rate measured after completion of the sine with dwell steering input exceeded the test standards." Sounds complicated.

Mazda hasn't yet given a timetable for owner notification, but 2009 Mazda3 owners can call 1-800-222-5500 to see if their vehicle is affected by the recall. Any Mazda dealership will be able to inspect and replace the stability control system free of charge. Hit the jump to read the official NHTSA press release.

      I love it when the ford recycle bin has problems. ESC is a very important safety device. What else is wrong with the car? Sear belts down work in emergency situtations? The brakes dont work? Tires blow out at 5k? LMFAO @ Mazda...oh yah and that whole ZoomZoom crap got old about 5 yrs ago

      You can check out the proposed standard: http://www.nhtsa.dot.gov/staticfiles/DOT/NHTSA/Rulemaking/Rules/Associated%20Files/ESC_PRIA.pdf

      I assume the final standard resembles it. Might find it interesting if you're into stability and controls. The "Sine with Dwell maneuver," appears to be pretty much jacking the wheel one way, then the other in a sine wave, hanging on at the bottom-most part of the wave for a little while (dwell) before neutralizing the steering. Not a professional driver, but looks like the Scandinavian flick to me.

      I haven't read into it a lot, but I'd gather the control system is designed to damp out the yaw rate within a certain amount of time, and this one didn't.

      i own a 2009 mazdaspeed, is that part of the recall?

      Still looks more "stable" than the 2010 model...

      I hope it's to install a bigger off button.

      The sine & dwell test is a Finnish Flick. So the fact that it failed this test means you can flick the car sideways even with the active nannies turned on. For your *average* driver, this is not a good thing.
        • 5 Years Ago
        Why? The average driver wouldn't push a car to the limits of traction.

      The complicated wording probably just means "you can hang it loose longer than we'd like it to before it kicks in" but they didn't write that because then nobody would bring their 3's in.

        And you know I'm right, I know you Mazda types. ;)

      I have a Mazda3 2008 and recently the power steering shut down on me in mid parking maneuver. I consulted the manual and it says holding the wheel at the limits of the turning radius for more than 5 seconds can result in damage to the power steering system. I've never heard of this. Evidently, the system shuts down for a period in such a situation. "Park the car in a safe place and let it rest for a while". Could this also be related to the 2009 recall issue, and should I contact the dealer about it?

      "the yaw rate measured after completion of the sine with dwell steering input exceeded the test standards."

      And they ONLY just noticed that? What dorks.

      I can say i did experience this problem while on 2 highway LA Crest. In a corner the DSC came in too abruptly and almost spin me out... I do think it kicks in too late and needs a firm hold of the wheel. I do not have my 09 anymore since was killing me on gas 17/21 on premium? no thanks
      • 5 Years Ago
      Sounds like it kicks in too late or not effectively enough.

      Now cue the 5000 comments about how stability control is stupid. Which is what people said about airbags in the 80s.

        Airbags rarely interfere with my driving :)
