Mazda CX-9 Maintenance and Repair



  • ewsncewsnc Posts: 14
    call your insurance company to see if it's covered under comprehensive. Years ago a squirrel got in the engine compartment of my 1-year old Accord and did quite a damage to the wires. The insurance picked up most of the repair cost.

    GOOD NEWS! The insurance IS going to cover the damage. Not only that but I kept my ZERO deductible on comprehensive coverage so it should cost me nothing. The car is at the dealer now and I should have the estimate tomorrow...

    I'm expecting that TSB 02-003/07 may apply to our CX9. In less thatn 25k miles the front tires are shot. Left front worst of all. I'm interested to learn what others have experienced regarding tire wear. We are in southern california so pot holes and other rough road conditions basically don't exist... meanwhile my other car has about the same number of miles and almost no tire wear at all.

    Just returned from a Niagara trip and it was a pain in the bu%% to remove all the dead bugs from the front of the car as well as from the side mirrors. Besides I was always worried about paint scratching.

    I'm contemplating getting the bug mask but wanted to hear from current owners.
    Those of you who have purchased the bug mask and/or the deflector can you please share your experiences with it ? Does it keep out all the bugs ? Is it easy to install and uninstall. Does the area under the mask get dirty ?

  • vinnynyvinnyny Posts: 774
    I'm in Florida where the bugs get really bad. I keep the front end and mirror housings waxed and spray a little Pam on the nose prior to longer trips. A little Simple Green and a bug removal spunge are all it takes to get those monsters off.

    I have a 2007 CX-9 and just replaced the brake rotors for the 3rd time....Rosenthal said they would cover it even though it has been a year since they replaced the second set.

    Has anyone else had the same problem? With only 37,000 miles on the car I'm considering not purchasing it at the end of the lease! :(

    This is common well-known problem for cx-9. The original rotors are too weak for a such heavy vehicle. The fix is trivial - install better rotors like slotted rotors.
    For instance:

    All cars have flaws and the rotor issue is not a big deal.

    Overall cx-9 is very nice and reliable automobile.

    I really love the car. We traded in an Isuzu Trooper for it. This is actually the 4th set of rotors.....the real frustration is having the service guy say it really was out of warranty when he knows I'm there for my 4th set of rotors!

    Thanks for the advice!

    Mine has 30K on it. Still on my OE set of rotors.

    Does the 2009 CX9 have a "newer" oil filter that would necessitate an extra $5 charge during an oil change? I was hit with this at a newer mechanic I went to for my last oil change and it sounded odd to me.
  • dmj155dmj155 Posts: 2
    Highly doubtful. Sounds like a scam to me. To my knowledge the powertrain is unchanged since prior years and the engine is designed/built by Ford Motor company in high volume, so there shouldn't be an "extra charge"...
  • That's what I figured. Thanks.
  • I called the mechanic again to clarify and they're now saying the mechanic was most likely referring to a "canister type filter" which they charge more for. Any thoughts?
  • davichodavicho Posts: 190
    I'd like to give "the mechanic" the benefit of the doubt, that he/she truly made an honest mistake because some Mazda vehicles (i.e Mazda5) do take a canister element replcement, but who knows. I would be the wrong guy to ask because I do my own maintenence and repairs (if it is within my abilities) because I don't trust just any "mechanic".
  • My husband and I purchased our 2010 cx-9 in July of last year. About a month ago when the weather in PA turned cold I began noticing a noise at start up. It sounds like a grinding sound. It only lasts for a few minutes when the brakes are applied and then it stops. However, the noise is getting louder and worse. I have also noticed a rattling sound at start up now as well. The car only has 7,000 miles on it. I'm going to take it to the dealership but wondered if anyone had any thoughts. Is anyone else having the same issue?? Could it be related to the cold weather??
  • I slid my 2007 Mazda CX-9 into a curb with the rear drivers side tire. It bent the arm that the lower end of the shock mounts to. Any idea on what the part for that arm is?

    Thank You!

    Here you go this should hekp you...Suspension diagram
  • My evaporator drain line is clogged. Any input as to how to clear (including how to find the line) will be greatly appreciated.

    You can hear the sound of water hitting the fan as you turn left.
  • My local mechanic has just had two CX-9s in the past three months with oil gelling problems. Have others had this problem? He recommended synthetic oil changes every 4 months instead of 6 to protect the engine- a costly expense but better than losing an engine. We drive many short trips and fewer total miles than most, so use synthetic. (Oil gelling in our Sienna, and the cost of the recommended additive led our shift to using synthetic oil.)
  • vinnynyvinnyny Posts: 774
    I recently went back to the dealer who sold us our 09 CX-9 to help my daughter buy a 11 CX-7. Dealer told us Mazda now specifies synthetic oil for all its SUVs. So, maybe that gelling issue is a trend and a problem worth addressing with the more expensive oil.
  • I need new tires as well for our CX-9 (FWD). Live in Minnesota and the last 2 years have been terrible driving with our original factory tires (67,000 miles and going). We obviously have lasted longer than some of the other posts. My question is has anyone purchased Falken Ziek 912s? Lots of posts for Yoko Parade Specs. Just wondering if the Falkens are good tire for winter driving.
  • we have a 2008 mazda cx9 , been smelling a gas inside the car, took to a mechanic yesterday , they lifted and saw a leak , they believe its coming from the housing? not sure how much this will cost our warranty was up at 60K we have 70K any suggestions.

    Hi. Am trying unsuccesfully to buy online a replacement for the passenger tail light of my Mazda CX9 2010. Any suggestions of online retailers with a good supply of autoparts for the Mazda CX9?

    I see six or eight brands of tail light assemblies at for ~$100 to $200+. Some right, some left. With that many choices there must be other outfits selling similar items online.
  • Thanks so much, I did find it! Beleive it or not I had tried at least ten online auto part sites and most did not have the exact part, and a couple had priced it at US$600+!. I will always use them from now on, first. Thanks!
  • steverstever Posts: 52,683
    Check for coupons. There's usually a 5% off one floating around for RockAuto.
  • I have a cx-9 grand touring. Two questions. I have been hearing this kind of stretching noise coming from outside when I turn my wheels, it doesn't happen that often but when I'm doing a slow turn it sound like rubber stretching. It's not a boot or leak anywhere or the tires, not sure what it is. Under the car looks great. Question 2, I've started to notice in the morning it takes the car maybe an extra turn or two to turn over and start after it's been sitting all night. It's kept in a garage where it's about 60 degrees, so no issues with sitting outside. I think it might have something to do with the fuel pressure regulator. I think the battery, alternator, etc are fine. Last night, I went out after it sat for about 5 hrs and started it, and it started like normal. Then this morning I started it again, no problem and was very quick. However if I don't start it in the middle of the night, it takes the extra couple of turns to turn over. I don't think fuel pressure is staying in the line like it should after the car has sat for an extended period of time. I also have bumper to bumper warranty until 88k, and I’m approaching 85. I want to take it in and have the issues looked at and also a good inspection. Anything I should ask them to look for that can be replaced through warranty so I don't have to be out of pocket down the road.
