    I haven't seen that one.

    Anyone still use magnetic oil drain plugs?

    Not a gimmick, but I'm not sure how useful they are. The mag plug does capture iron & steel particles too fine to be caught in the oil filter. I just changed the oil in our Prius Prime, and I wiped an expected small smudge of gray particles off the magnet, and I've seen the same thing on other...

    Shopping for a CX-9, should I avoid 2020 and earlier?

    And read the fine print before you buy the car and get the warranty. If the warranty says something like, "all oil lubricated parts," drop it. The cracked cylinder head isn't covered in this case.

    2007~2015 Mazda CX-9 water pump replacement/service expected costs?

    Yep, the cost for a reliable used car has gone through the roof. Add high financing interest rates and.... What other necessary work can be done while the engine is out of the car and that work is easy to get to? I'm not familiar with the Ford engine in your car, just what I've read here. If...

    CX-9 Engine overheated

    The worry with our engines is if the cylinder head cracks where it carries the weight of the exhaust manifold and the turbocharger. Coolant leaks out, the engine overheats, parts expand unevenly, the head gasket doesn't seal, coolant gets into the oil, the engine is damaged, and you now need a...

    The Car Care Thread

    I've been very pleased with 303 Nano Graphene Spray Coating. They say that it uses graphene oxide to increase adherence to the paint. The surface needs to be in good condition...clay bar or buff with a suitable polish or cleaner as needed...then just wipe on (section at a time), let dry (not...

    2016~2023 CX-9 Radiator fan issues

    1) The ground wire connections need to be clean and tight. 2) The overheating could be caused by the wiring to the fan motor, the fan motor, the fan motor thermostatic switch, the grille louvers, the coolant thermostat, or a coolant leak (hopefully not, that would probably be a cracked cylinder...

    Parasitic battery drain (2016 CX-9)

    So the incompetent "technicians" at the dealership failed to fix the problem and charged you $1,100. The problem was the water leak; the symptom was the wet & grounded buzzer. What else have they overcharged you for? I haven't heard of any problems in the Gen 2 PTU...do these cars have a...

    CX-9 Engine overheated

    The charge air cooler (intercooler) is air cooled; no coolant involved. It is located below and behind the front license plate. Do you have dried green coolant residue on the back side of the engine? Is the engine oil milky appearing? Even if not obviously milky, send an engine oil sample to...

    Towing with your CX-9

    Not exactly. Think of putting a pair of wheelbarrow handles into the car's rear bumper somehow and lifting up on them until the tow vehicle is now level. Chain the handles to the trailer tongue, and you've got weight distribution. Change the wheelbarrow handles for spring steel bars, and...

    Nitrogen Inflation?

    The only real advantage of using nitrogen is that it is very dry. Moisture in the air in the tire can rust steel wheels. Compressed air can be run through dryers to get equally dry, but few shops spend any money for these air dryers. The shop buys or leases a nitrogen inflation generator...

    2016~2023 CX-9 41K spark plug change, found NGK plugs in the wild

    Working vs. working optimally. That can be a difference. At 40k miles new plugs gave the car a bit more giddy-up. The old plugs were working smoothly. The new plugs just worked better...more optimally.

    Purchasing Used 2021 CX-9 GT, add warranty?

    Tchman makes a very good point. If one decides to get an extended repair plan, shop around. These things are great for the dealership. Zero inventory cost. Whatever they make on it is pure profit. The same item from different dealers may have different cost but exactly the same coverage...

    2016~2023 Anyone have CX-9 parking brake actuator problems?

    It sounds like the calipers might be the cause. The cost of new calipers will be offset quickly if you can forego another early brake job.

    2016~2023 Anyone have CX-9 parking brake actuator problems?

    I think I found the source of my problem. It's different than what mcd found. There is a Technical Service Bulletin 04-001/18 that describes rear calipers that don't release fully when the parking brake is released. This is only on early 2016 CX-9s (mine) and early CX-5s. 2016 CX-5 vehicles...
