Mazda CX-9 2WD

Hi All, Joined the club September 2025 when I found a sweet deal on this 2022 CX-9 Touring Plus. It required a trip out to California from Utah but was worth it! Was able to drive her back the same day. There was a crazy storm on the way back and lots of opportunities to get acquainted with the car. Dealers here in Utah are crooks and I saved around $5k buying out of state. Was a scary process as was my first time buying out of state but I had Skymiles to burn and the dealership I purchased...

Hey. I got this used with the OEM 18 inch wheels. Got used 20s and put all seasons on them and kept the 18s for winter tires. For winter 2021-22 I bought used Hankook i-Pike winter tires from someone with excellent tread but the DOT on them is 2016 year. Still plenty of tread but the rubber is 10 years old so I figure I'll replace. What I had was 235/65/18, which at the time before buying the used tires, my dealer said yes, that size is fine. They have served me well the past few years so... Read more

Need a car that I will drive roughly 6000-8000 miles /10,000 - 12,000 km an year on the highway (Europe) at 80 mph for 3.5-4 hours at a time. When I need to drive in the city I prefer to rent small EV cars, so I get cheaper parking. For 25,000 euros I can get a 2016 CX-9 at 60,000 - 80,000 miles /100,000 km - 120,000 km or a 2019 CX-5 at 50,000 miles - 60,000 miles / 80,000 km - 100,000 km. Prefer to get petrol as they seem more reliable and there will be 2-3 weeks at a time that I won't... Read more

Hi everyone, I'm a CX9 owner from Australia, and I'm currently working on upgrading the FSC on my 2016 CX-9 (TC). My original FSC is TK56-67XCX (Strategy: TK56-67XK2-B) and I want to upgrade to GSH7-67XCX-T (Strategy: GSH7-67XK2-S). My radar is TK80-67XA1. I've replaced the Gen 1 TK56 FSC with a newer Gen 2 GSH7 unit. FORScan successfully recognises the new camera, and I've performed as-built programming and module initialisation. However, I'm still getting the following DTCs: FSC... Read more

Hi all! This seems to be a pretty common thread topic on some of the other boards I visit. I did a search and couldn't find anything posted for the CX-9, so I figured I'd create one. Mods, if there is already a similar thread, please feel free to close this one! Did you just carve out a few corners on the mountain roads or take the CX-9 for a road trip? Install a new cosmetic piece? DIY'd a cabin filter install? Swapped your winter wheels out for your summer set (or vice versa)? Show off... Read more

Hi everyone, first time poster here hoping to get suggestions on what to check/replace or solutions. I have a 2017 Mazda CX9 GT AWD with 320,000KMS, this year it's developed a rocking (back and fourth) on steady acceleration from full stops. The rocking will go away if I remove my foot and then accelerate slower or faster. I've tried it in Manual mode and appears to mostly happen in second gear. It rocks me in my seat back and forth as I accelerate unless I stop accelerating and slow do or... Read more

Hello all - need your thoughts. After a check-engine light, I'm told my 2019 CX-9 with 112,000 miles needs a new cat and both O2 sensors. Big bucks. Independent mechanic who services my car (very reputable) says new cats can fail at 100-125k. All that said - I had the cylinder head replaced back in 2021 at 35,000 miles due to the famous problem. I've had no issues regarding that repair that I know of. Now however, I'm wondering. To me 112,000 miles is too early for a cat to fail. I'd had... Read more

I did something I wouldn't typically do yesterday. I took a 230,000 mile car to the dealer for service. We bought the 2016 CX9 with 200k miles (highway miles, he was a traveling salesman) in 2021, and have only done oil changes since. Due to my deferring maintenance the front rotors were heavily grooved. Our local Mazda dealer's service department is not crazy expensive (we bought our 2021 CX5 new from them so I am familiar with the service dept) so I took the CX9 in for front rotors... Read more

Hello, I took all the parts off to get too spark plugs now engine wont start. It turns over and for a brief sec it wants to start but won’t. Does the computer need to be reprogrammed and does anyone know the procedure? Thank you, Alex

Has anyone run into a similar problem on their 2nd gen CX-9's screen micro-cracking? It seems like this is a known issue on other Mazda models and appears to be exacerbated by temperature swings. Unfortunately, I am just out of the warranty period, so I am wondering if it's even something that Mazda would cover

Moderator edit : This is a copy of a post originally made in another thread. This thread was created for easier reference. Mazda recently put out this TSB for coolant leak because of cracks in the cylinder head. As reported by many here it seems to affect the 2.5T 2016-2020 CX-9 as well as 2019-2020 CX-5 and 2018-2020 Mazda6

Have a 2018 CX-9 GT AWD with about 38.3K miles, noticed air from heater wasn't blowing as hot & slowly over the past couple weeks that air wasn't getting hot at all. Last Sat while out, had msg on dash/Hud show to pull over immediately. Took to dealer & was told that I have a cracked cylinder head in the rear by the turbo (dealer sends video with a walkthrough done by the tech/mechanic). Thankful it's covered under powertrain warranty, but being told part is on back order & may not be fixed... Read more

**Moderator Edit** ​ Please review the Mazda Dealer communication below. Mazda has issued a Customer Service Program (CSP11) to extend the limited powertrain warranty to 10 years/120k mi for any owners experiencing the coolant leak. Further, any owners who have paid out of pocket for these repairs may be eligible to receive reimbursement for costs incurred. This CSP11 is applicable to the following models (if equipped with the 2.5T): 2016-2020 CX-9 2019-2020 CX-5... Read more

Hi guys. I have a 2019 CX-9 whose front grille molding got a minor crack. The crack is only in one piece, but to replace it, I think the whole front grille and cover needs to be taken out to access the piece that needs replacement. Then the whole thing will be put back in. I got a quote from a local body shop on the replacement of that one piece, and they're charging $300 to re-calibrate the front sensor that's behind the Mazda emblem in the front grille. They say that this calibration is... Read more

All 2016-2019 CX-9 owners should be aware the front bumper likely will crack due to a design defect. Mazda is well aware and issued TSB #09-022-20-3720 . Hope yours cracks while still under warranty. If not, Mazda may "assist" you, but they will not pay the full cost of the repair. I noticed mine while washing at 38,000 miles, just out of warranty. I took it to the dealer, whom said they'd had a few cases and they had to submit a case to Mazda and not to worry. To my surprise... Read more

2013 CX-9, 132,000 miles Just bought this car, unknown history. Tires have most of their tread and no apparent defects. The right-front corner emits a low growl roar starting at 20 mph and increasing pitch with speed. Steer left and it increases volume; steer right and it goes silent. I pulled each wheel and found the CVJ boots intact, no slack in the CVJs. No movement from shaking the wheels any direction. Of course I couldn't spin the wheels fast enough replicate the sound. Have you... Read more

After trading down from a leased 2021 CX-9 to a financed CX-50, we opted to upgrade, again, to a CX-70! We missed the trunk space and comfort from the larger SUV! Turbo S premium, think we got a good deal on it at $50,500 after the $500 loyalty rebate.

This is the first video in a technical series I'm putting together on the Skyactiv Drive transmissions. The transmission in the video is from a FWD CX-9 and is the one used in all the factory turbo cars and 2.2 diesels. Mazda calls it a GW6A-EL and the CX-5, 9 and Mazda 6 Turbo use this specific version. The Turbo 3, CX-30 and CX-50 use a slightly different version that has a case shape in the rear to allow it to fit in the smaller chassis. The important parts are all the same. This video is...
