Mazda CX-9 Problems



  • Same problem with what feels like shuddering at between 30-40mph. Wife found that ifs she uses manual mode it does not happen. Seems to be in Auto mode only so could be software issue. Tranny fluid looks good. Fuse was good as well. WE ARE LISTENING.

    If it's only happening in automode, that might suggest you have the bad transfer case issue...but I'm not sure.
  • Same issue on mine 2011 Mazda Cx-9 some sort of gas smell .. pretty much same answer from Mazda dealer ..
  • I've same issue 2011 Mazda CX-9 GT .. Same issue when in reverse, drop it @ Mazda dealer , they have order parts will be given me in few days, they say it's not derivable condition it may damage more so we can't give you back, as I didn't have any other car, and strange they don't give loaner or anything on their problem luckily few thousand left on warranty ! .. that's crazy.. car runs gr8 but what's the point if these kind of issue!
  • I have the same problem. Can anyone help with this one
  • Same EXACT issue with my wife's 2008 CX9. I can root this back to around the same time we had the tranny fluid changed by a non-dealer location i think. My regular mechanic said that they know the CX-9 is picky on the type of fluid used. I have not had time to take it in yet to check it out at the dealer or go back to the place that did the work. Any updates from you on your situation? Please email me if you can.
  • The update for me is that Mazda (USA and two local dealers) have acknowledged they have problems with the drive shaft, transfer case and brake bearing but as my car is outside of their 60k mile warranty, I'm out of luck and out of $4,200. I had to fix it just to get it to the point so I could trade it. No more Mazda's for me. These are clearly safety issues and everyone I talk to locally with the CX-9 have similar issues. I've talked to may 25 people in the last 60 days and all are various stages of exactly the same problem. Sorry, wish I could offer you better news.
  • I have a 2010 CX-9 and the whine in 6th gear began at about 30,000 miles. Like everyone else posting here, it starts at 42 mph. I clearly is not a wind or speed issue because if you downshift while going 42 mph from 6th to 5th, the noise goes away. The dealer went for a test drive with me and says he is going to contact Mazda but it's been a month now and nothing has happened. Can anyone please give me an update on this issue? Has anyone received satisfaction?
  • Mazda CX9 vibration (when shifting into 4th gear) finally fixed no thanks to Mazda techs who were just guessing all the time. They replaced the ABS and then the rear drive shaft, vibration was still there, got all my money back.
    Finally went to independent garage who agreed it is a transmission problem, and asked if I have had my transmission serviced recently. Told I had a few months ago "at Mazda", he asked how much I paid, told him it was $180., he said that was pretty cheap and suspected they put in the wrong transmission fluid. Couldn't prove it, but he said Mazda CX9 auto transmissions are "high end units" (like BMW. Mercedes etc) and require high end fluid. Cost should be in the $250. range. He recommended putting the correct fluid in, I agreed. The vibration has disappeared and it shifts gears perfectly. Told Mazda, haven't had a reply yet!

    I think this is a new one. While backing up, it just went dead. Nothing obvious. No unusual warning lights. Restarted on first try. And has run okay since. But very strange - any ideas??

    I have a 2010 CX-9 and experienced a vibration this weekend while driving at about 40 miles/hr. It seemed like the car was struggling tto get to speed 6 from 5. When I shifted to manual the problem was not as apparent. The check engine light flashed on/off. Car has 60K on it. Just had it serviced last week!! Took it to the dealer and waiting for the phone call. Luckily I purchased extended warranty on this car (valid upto 100K miles) since this is my first Mazda. Wondering about the quality now if this is the situation at 60K.

    @charron6 - I just posted about my experience with a 2010 CX-9. I think I may have a transmission or transfer case issue too. Will let you know what I find out from the shop.
