    2015 CX-9 Rear hatch issue

    It won't be a fuse. If a fuse fails the operation won't be intermittent. The fuse protects the wiring. If it fails there is an electrical fault that must be repaired. Just replacing a blown fuse simply yields a new blown fuse. How many switches are there to open the liftgate? (My 2016 has...

    2013 CX-9 Grand Touring - P0016 — Timing Chain

    Just a note...jal, roller chains don't stretch.* The pins & bushings wear resulting in looseness, loss of strength, and, yes, lengthening due to the larger diameter holes in the bushings and smaller diameter pins. *And, an under-spec, overloaded roller chain can have some stretch in the plates...

    Pretty bad case of vibration and humming noise

    Was it balance or something else that caused the tire vibration? Did the guy have to reposition the tire on the wheel? Good luck. Let us know what finally works.

    2016 CX-9 2.5T Cylinder Head Replacement

    It is very disappointing that Mazda won't stand behind their mistake with these heads regardless of the mileage or warranty status. This is neither wear nor abuse, it is simply Mazda's error in manufacturing or designing the heads.

    2016~2023 CX-9 AWD - rear clunking noise

    The rebound dampers, the struts & shocks, are hydraulic units. If the seal lets hydraulic oil seep out, it's time for new ones. You'll see or feel the oil, it's not just "wet."

    2016 CX-9 Sport - Tires/Vibrations

    Always be sure the service writer puts down on the work order what the problem is, not just his guess on what is to be done. If the problem is written on the work order, and it's not fixed, don't pay. You didn't ask for a certain procedure, you asked for your problem to be fixed. No fix, no pay.

    2016 CX-9 Sport - Tires/Vibrations

    About alignment...look at the wear on the tire tread. There are lots of guides on the internet. If the fronts are worn more on the inside edge, or the outside edge, alignment is needed. Or uneven wear on the rears. Or the car pulls to one side on a flat level road. Otherwise alignment is...

    Greetings from Michigan

    The head gasket is not the problem. On earlier years the cylinder head wall cracked from the weight of the turbocharger. After the coolant was lost through the cracks, if the car wasn't stopped & parked in time, the engine overheated, parts warped, the gasket gave way, coolant entered the oil...

    Review of K&N Air Filter for Mazda 2.5T engine

    And not just K&N. The same applies for every "performance" filter. The choice is yours. A $38 Mazda air filter, or a $32 WIX or equal top after market brand, or a $65 K&N with questionable filtration. (I'm not sure I'd get the $15 Fram. I don't think so.)

    Steering making noise (2019 CX-9). Any ideas?

    One needs to read the fine print on the last page of a TSB to see if Mazda is paying for the fix for cars out of warranty or not. Safety recalls get every car fixed at Mazda's expense. TSBs...maybe, often not--like the cracked cylinder heads.

    CX-9 Wandering on highway

    So you've had multiple alignments and the problem didn't change? And new tires and the problem didn't change? The hardware is about all that is left. Schedule with a sit-down with the service manager, not just a service writer. Get his ideas on how to fix it. He has resources at Mazda USA...

    Mazda extended warranty for CX-90

    Keep in mind that these products are neither a warranty nor extend anything.* They are prepaid repair contracts. Contract law is not as beneficial to the consumer as warranty law. As a contract they cover exactly what the fine print in the contract says IF you follow all the requirements they...

    2021 CX-9 Burning oil

    There is no need to change good oil, and the testing lab documentation tells if the oil "remains suitable for continued service."

    2016 CX-9 2.5T Cylinder Head Replacement

    Send an oil sample to a testing lab. If there are excessive wear particles (metal) or coolant in the oil you may need a new engine. Here is one lab, the test costs $35: https://www.blackstone-labs.com/engine-types/gasoline/

    2021 CX-9 Windshield Wiper Setting question

    I found the Mazda auto mode less effective that the Toyota auto mode. I prefer my CX-9 wipers in non-auto intermittent mode as Michal describes.

    Towing with your CX-9

    Lubricants are damaged by high temperatures, more accurately time at temperature. A brief spike at a high temperature is less damaging to the lubricant than longer time at a high temp. ATF is a lubricant as well as a hydraulic fluid. If run hot for long an early change of the lubricant is...

    Poll 2.5T Coolant Leak/Engine Replacement

    I disagree. Was the testing extensive enough? Did Mazda run round-the-clock driving on a simulated street track with pro drivers for a few hundred thousand miles? This probably would have shown up. Or were the heads cast under-spec? And was adequate quality control testing done? As well as...

    2016~2023 CX-9 Brake Life

    The Mazda pads do not have squealers built in to warn when the friction material is getting very thin. All 8 pads need to be visually inspected for thickness at each tire rotation. Ask for the actual thickness in millimeters, not just a guess at the percentage remaining. 2 or 3 mm is a good...

    2007~2015 Changing CX-9 transfer case gear oil (photos)

    This thread is for the generation 1 CX-9 with Ford engine and driveline components. The gen 2 CX-9, 2016 to 2023, has different components, not Ford. Evidently the new CX-90 has even different components. I would not follow any gen.1 recommendations in the CX-90. With any gearbox oil change...
