The bigger issue is the water pump. No way of knowing if the internal gaskets have failed until your engine fails, since the timing chain runs the water pump and when it goes, the coolant ends up mixing with the engine oil. If it is caught it’s the entire front subframe and engine out job just to replace the water pump. Four figure bill.
Common problems Brake booster Window motors Water pump failure (loss of coolant) Ignition coils Transfer case failure Cooling fans stay on cause of blower relay Front wheel bearings Torque converter shuddering in and out of lockup on the highway Drive shaft bushing wear causing vibration Have also had a few where the pcm randomly fails and causes a crank no start
Fortunately, I have a 2014 CX-9 and haven’t had any of those issues. The reoccurring issue has been the window regulators stripping and the automatic windows stop working. I’ve replaced four of those so far. After 8 years of ownership and 160k miles later my CX-9 has mostly trouble free. Hopefully by 2014 Mazda has worked out most of the issues of this generation.
Everything in this video is great except for the transmission part. I have a 2011 CX-9 and the TRANSMISSION IS NOT A SEALED UNIT AND IT IS SUPER EASY TO CHANGE THE FLUID EVEN THOUGH THERE'S NO DIPSTICK UNDER THE HOOD, I change my fluid every 15K miles using only the EXACT CORRECT FLUID AND NOT SOME ONE FLUID WORKS IN EVERYTHING. I have close to 200K on mine and the transmission shifts flawlessly. There was a TSB on the transmission rough shift and that was covered under the warranty when these cars were new and it was a simple reprogramming of the TCM Transmission Control Module.
Absolutely. I use only the exact OEM ATF marketed by the transmission manufacturer, AISIN, less than half the price of the same thing rebranded Mazda. There's no filter to change and no pan to drop, couldn't be easier, plus I installed the manufacturer deleted under hood ATF dip stick and tubing.
I own this model cx9. Surprise the brake booster didn't make the list. My was fairly low mileage, 2011 currently at 70k miles. Boost went bad around the 50k mark. Other issue was the cam solenoid. Other than that, cars been reliable
Tengo una 2010 desde nueva, me encanta, su motor es muy potente, 0 a 100 como un deportivo, su comodidad es increíble, no la vendo porque me dan muy poco la verdad, el único dolor de cabeza es la transmisión, es delicada, ocupa sus cambios de aceite frecuntemente y aún así, se patina a veces y entran de golpe los cambios, todo eso cuando se calienta mucho, en climas fríos funciona perfectamente.
Mazda is very reliable imo. Almost every car has their problems. As a consumer I’m still surprised no manufacturer can build a vehicle that doesn’t end up with recalls. As long as they been making cars it’s unreal. But I guess mechanics would be out of business if they did.
Thanks I had that squeaky noise and they changed the strut but it still made the noise. They had to grease up a few things so tomorrow I'm going to find out exactly how they fixed it. Kinda of regret buying a Mazda from a Toyota dealership. I'll keep you guys posted.
My 2012 has a transfer box that gets too hot and burns the lubricant (if that’s the right term) and required a 4k fix. I’ve also had misfires on two different cylinders.
I have a 2010 CX-9 FWD Touring with 161K miles. I live in the lake effect snow area with lots of road salt, and its been pretty reliable. Exceptions are window motors, I'm on second driver door handle, and I had to replace liftgate handle because the mechanism was completed rusted. My SiriusXM satellite antenna on the roof no longer works, I didn't want to replace since it means removing the headliner. I can only pickup SiriusXM from local terrestrial repeaters so limited usefulness. The bluetooth on the factory head unit (mine is the upgraded model with small screen for backup camera) is no longer compatible with modern iPhones - so I've had to start using 3.5mm aux jack. It still works with ancient iPhones, so seems to be a protocol compatibility issue. I recently had an exhaust leak patched due to rusted exhaust pipes, but original muffers and original resonator look great despite all the years of road salt.
210 on my 09 CX-9 only issues are owner errors. i had to replace my alternator because i spilled oil on it, ultimately had to replace the radiator too because one of the connection snapped right off . only major issue I've been having lately is my transmission starting in fifth gear. could be the reprogramming you spoke of. other wise aside from the diy because ford designed the car mines was built in japan so i contribute that to its lasting.
So after a 2-3 hrs driving in this summer awhile driving all the lights came on then as we got closer to home the LCD died and just about 5 blocks away the AC stopped working my amp meter showed from 14amp - 8.4 amps after all that we made it home safe and I charged the car battery backed up to 14.00 amps the next day we drove about 1-2 hrs AC on and everything the same day amp dropped to 12 amps the battery light came on that same day I’ve placed ordered for alternator before I even plan to change it out thought I take it back and get the car battery and alternator checked while I’m on the road haven’t made and changes yet. Orielly did the test while the car was on and their test machine said the battery and alternator was good? What can the problem be?
I have been having some strange noise from the engine on my cx-9 mazda 2008. However, my car just went off yesterday and once I start d car and I engage the gear and put on the ac the vibration is so high and makes serious noise from the engine. Kindly advise
Thinking about buying a 2008 Mazda CX 9 but the seller says it idles rough. About how much should I expect to pay a mechanic to replace the ignition coils?
My transmission slams into Drive abd Reverse. A huge boom when it shifts. Any idea what it could be? I looked at the transmission torque dogbone but it looks to be in good shape. Bushings not cracked.
+willmann30 We wouldn't be able to diagnose an issue like that here, you may want to have a local mechanic take a look at it. Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
I have this model CX-9 2015. I had the last issue and replaced all my plugs and coils. The light still is on and it still shakes at stops and I’m park. New code is p302. What is your suggestion?
Also watch out for the transfer case very hard to change the oil in here. No drain plug. It has to be sucked out if it's not too late and it's already turned a lard
Actually I need your help in something I have struggled with for the past 4 months I have the gas line it's not coming down only coming up I have to fill up the car every time I go because I don't know the gas when we'll be empty because it's stuck and not working and I want know what's the main problem???

I have actually changed my transmission fluid and filter in mine. Solved the hard shifting.
The transmission fluid absolutely is replaceable. The fill plug is located under the air box.

These older CX-9's are fairly reliable crossovers.

Add these too..
Tie rods, window motors, A/C drain blockage..
+Chris Munroe Thanks for the feedback!
I sold my 2011 XC9 today and I already miss it 😢
Good feedback except on transmission issue they are definitely serviceable and despite what Factory states you should do it every 30-40 thousand miles
Thank you for this video. It helped a lot. I watched in the middle of the road with a flat tire
Tengo una 2010 desde nueva, me encanta, su motor es muy potente, 0 a 100 como un deportivo, su comodidad es increíble, no la vendo porque me dan muy poco la verdad, el único dolor de cabeza es la transmisión, es delicada, ocupa sus cambios de aceite frecuntemente y aún así, se patina a veces y entran de golpe los cambios, todo eso cuando se calienta mucho, en climas fríos funciona perfectamente.
There are several of the cx9 on sale online that have well into the 200k miles on them still selling for 5or 6k

What if your AC is draining water into your passenger floorboard

No. 1 should be the transfer case.
Transmission fluid can be changed and should be changed

You forgot the Radiator. They all leak...card board fittings. Absolutely a transmission change is required.
Thinking about buying a 2008 Mazda CX 9 but the seller says it idles rough. About how much should I expect to pay a mechanic to replace the ignition coils?
Fob key is broken but the actual key doesn’t want to turn on. What could possible be the problem?

Excent tips My friend....✓
Most definitely brake booster
How reliable is suv
137,000 no problems at all.
No such thing as a sealed transmission that's a piss poor excuse to make money off of people that don't know much about cars
Unos de los vehículos más malos que ya fabricado una marca , mi tío tiene una y eso vive en el taller. Dan muchos problemas de transmisión y motor.
