2010 Mazda CX-9 – Click above for high-res image gallery

We here at Autoblog love seat warmers, and we're glad to see that more and more automakers are fitting this lovely amenity as either standard or optional equipment across their full range of vehicles. However, like all electrical gadgets, occasional glitches are known to pop up every so often, and Mazda is now recalling many of its 2010 model year CX-9 crossovers due to faulty seat heater units.

According to NHTSA, the front seat heater units in the CX-9 can overheat in extremely cold conditions due to insufficient electrical grounding, which can cause the seat cushions to burn or even catch fire. (Yikes!) To fix this potential hazard, dealers will install additional ground harnesses to the heater control system, and may even replace the seat heater control unit, if necessary.

Owners can contact Mazda at 1-800-222-5500 for more information. The official safety recall will begin around March 9, 2010. Follow the jump to read the full details in NHTSA's press release.

      Somewhat off subject here, but I imagine it won't be long until the CX-9 gets the new smiley face, right?

      I bought a 2010 CX9 from a Mazda Dealer in Shrewsbury MA. The dealer has been diligent in NOT TAKING CARE of customers once sales are complete and simply focusing on new sales. I am sure this recall will be another example of the dealer forgetting the customer after the sale...we will see...but beware Mazda dealers are not all the same. And recalls are the job of Mazda dealers to implement. So far all questions and issues with my Mazda have been improperly handled. I even had a windshield that cracked on two sides at the same time while driving! The crack met in the middle of the windshield. Beware of this dealer. Beware.

      Customer of mine about five years ago had this happen on an older Discovery. One of the heating elements shorted out and got so hot it burned right through the leather and his pants. It only took a few seconds so he didn't really have a chance to shut it off before it had burned through.

      Even after shutting it off the seat was still very hot and so very difficult to drive. Could be a safety hazard in bad traffic.

        Find me the original song remastered on CD or MP3 and you've got $20. Remakes won't do.

      Reading this bleary-eyed, I saw: "...which can cause the seat cushions to burn or even catch fire. (Yikes!) To fix this potential hazard, dealers will install additional seat cushions to burn or even catch fire."

      Reading in a straight line is hard when skipping up and down also makes sense.

        "According to NHTSA, the front seat heater units in the CX-9 can overheat in extremely cold conditions due to insufficient electrical grounding, which can cause the seat cushions to burn or even catch fire. (Yikes!)"

        And if someone farted on it...

        CONFLAGRATION!!!

      I've never seen that Mazda V70 clone before.
      • 4 Years Ago
      Actually the major issue isn't roasted buns (nuts?) its drained batteries.

      Oh, and I sent in this tip last week, thought you'd wait until it was official AB.

      As the seat began to scorch my ass I assume I would have the cognitive ability to switch off the seat.

      I dont see how much of a safety hazard this is but it is good to see that Mazda is sacking up and fixing this defect.

      My old Volvo 850 had seats heaters that outrageously hot, (not ass burning) and often I would have to switch them off because it got too uncomfortable.

      Seems like this is a familiar recall, has this same thing been a problem for other manufactures? I faintly remember making jokes about this before.
