    2007~2015: CX-9 Factory Stereo (Bose Amplified) Replacement Problem!

    Is a return possible and get one from a place that does provide a harness, or has that ship sailed? At the very least they should be able to give you steps to hard-wire the unit. Very poor customer support in my opinion.

    2007~2015: CX-9 Factory Stereo (Bose Amplified) Replacement Problem!

    What kind of new stereo are you installing and where did you purchase it? I am asking because I installed a BOSS Carplay capable new unit and I purchased it from Crutchfield. They provided the custom harness I needed and it was plug and play for me. Perhaps you can reach out to them regarding...

    Good replacement battery for the 2021 CX-9?

    If you are a member at Sams Club they have good deals on batteries and an AGM battery may hold up better than regular flooded lead acid in your case.

    2017 CX-9 went into limp mode while merging. No issues after restart

    An OBD reader will now show 'module' errors, if any did occur. You need a scanner that speaks to each module and retrieves the manufacturer codes. There are Launch scanners on Amazon that perform this function and if you plan on keeping the car for some time and are somewhat DIY it may be worth...

    Frozen winshield wiper fluid

    For the price of some decent washer fluid I'd say you'd be better off buying your own and topping it off vs. whatever the dealer is using.

    2010 CX-9 Oil leak from a pinhole - Need help to identify

    Are you sure that the oil is not coming from higher up on the engine? The reason I ask is that is the cylinder head you are looking at and the likely hood it developed a pin hole is pretty remote but it is possible. Higher up on the engine you will have the valve cover for that head and they can...

    Cruise control isn’t working…Any ideas? 2010 CX-9

    They do but a local shop may be more more cost effective. It's really a 10 minute job with the proper scan tool.

    2010 CX-9 Sport AWD Head Unit Upgrade Issue with 3 Button Steering Wheel

    I installed a BOSS unit in my 2012 GT and it looks almost identical to the Bronco Boy install. It does differ in that the mic is under the steering wheel and it works well there. I also ran the USB connector over by the drivers side. I purchased my setup from Crutchfield some time ago but it...

    Cruise control isn’t working…Any ideas? 2010 CX-9

    You need a professional scanner, not just an simple OBD scanner that reads the generic codes common to all vehicles. It reads all the 'modules' (computers) in the vehicle and gives codes for each if any are present. There is likely some manufacturer specific code on one of the modules that will...

    Cruise control isn’t working…Any ideas? 2010 CX-9

    Find the fuse that controls the cruise control and check it. If it's good then you need a full scan of the vehicle with a decent scan tool, without that your grasping at straws.

    2016 CX-9 Fuel Filter Replacement Tips?

    I doubt it's the filter also. It's not like it's not getting enough fuel to cause a leak and the leak is likely the cause of the code. I don't know if that system has a return line to the tank but it would make sense in this case if the leak is at the rear of the engine. If you carefully inspect...

    Help! Can't lock doors on 2009 CX-9

    If the door ajar lamp is on then you likely have a bad 'striker switch' at one of the doors. I cannot recall if having one of the doors open prevents the vehicle from locking but if you can determine which one of those switches is bad that may be the fix.

    2011 CX-9 Electrical lock issues

    Either what sm1ke said or your door striker switch is broken on one of the doors. The fact that your courtesy lights stay on and the door ajar message is a clear indicator something is up. Not sure what door may be causing that but you'll need to figure that out. I suspect the vehicle won't lock...

    Oil filter housing cross threaded? 2020 CX-9

    They do make thread chasers that you can run down with a socket vs. using the stock setup with the longer handle. However, at that point the cost of the set may be close to the replacement part. If it is that accessible maybe it is your best route.

    Oil filter housing cross threaded? 2020 CX-9

    You should remove the filter and closely inspect the threads on the housing and the filter you used. That will give you an idea of whether you have a problem or not. Spin on filters usually only need a good hand tight seal so it does sound like something is going on with your setup. If the...

    Difference between CarPlay Upgrade Hub SKU numbers?

    Usually a different last digit represents an update to the prior version. In the case above the "E" would be the latest update to the hub.
