    2017~2025 CX-5 Chirp Noise from Automatic Transaxle on 3-4 upshift - Bulletin 05-005/23

    I'm so glad I opted for the 2017 instead of the 2018 back in early 2018 when I bought my CX5. Mazda dealer had a bunch of new 2018's on the lot and a prior model year 2017 on the lot. I read about the CD and I had a strong gut feeling that it could turn out to be problematic. So I bought the...

    2.5L NA Cracked Cylinder Head with Oil Leaking

    I have yet to see a 2017 model year vehicle have CD. If it did, it would be listed on the window sticker of the vehicle. It would also have a "M" in the 8th digit of the VIN, if it has CD. My 2017 has a "L" in the 8th digit, so no CD for me.

    First Auto Tranny Fluid Change at 95k (2015 CX-5)

    The "lifetime" fluid claim is just a marketing/EPA claim. Lifetime means the lifetime of the warranty, once that expires, the manufacturer could care less if the trans fails. No hydraulic fluid that is subjected to heat and friction will last a "lifetime". Excavation equipment uses similar...

    First Auto Tranny Fluid Change at 95k (2015 CX-5)

    I would drop the pan and clean out the magnet, plus change the filter. The magnet catches metal particles, like the clutch material. I did a drain and fill at 25k. Then another drain and fill at 50k. Then I did the pan removal and filter change at 53k. There was definitely material on the...

    Engine hum when shut off (2023 CX-5)

    I believe it's the fuel pressure regulator as it's cycling fuel back to the fuel tank. It's not the LED fans.

    Switched to 5W-30 from 0W-20

    The Idemitsu 5w-30 synthetic meets the GF-6 standards. I bought a 5 quart jug on RockAuto for $31 plus shipping

    Idemitsu is also recommended for Mazda's

    Anyone use LiquiMoly?

    2013~2016 CX-5 Services/maintenance required?

    Entering the fuel tank is not what I call "serviceable" :) The fuel filters that I had on other vehicles would take 5 minutes to replace as they were "in-line" on the fuel line side. Not inside the gas tank. I assume one has to drop the entire fuel tank to access the fuel pump and filters?

    2013~2016 CX-5 Services/maintenance required?

    Yes, I just did mine at 53k miles and there was a decent amount of steel clutch material on the magnet. Trans works great but that magnet needed to be cleaned. Replaced the filter also. Once that magnet gets overwhelmed, it will start sending the metal into the trans. It's a pain with the trans...

    2013~2016 CX-5 Services/maintenance required?

    The CX-5's don't have an accessible/serviceable fuel filter, correct?

    2017~2025 CX-5 Coolant questions

    How often should the coolant be drained and refilled? Every 6 years or 60k miles?

    I want to buy a 2023 CX-5. What are the major issues?

    I swapped out my mini doughnut spare for a full sized rim spare. Yes, it doesn't sit flush under the rear cover but having a full sized spare is such a peace of mind. Who wants to deal with a small spare that cannot be used on the front tires anyways and cant go over 55mph. I'm fortunate I got...

    I want to buy a 2023 CX-5. What are the major issues?

    Why doesn't Mazda just get rid of the CD? The gain is maybe 1mpg but the risk and problems are just not worth it.

    DIY ATF Drain/Fill

    Ran i I used a thermal laser gun to get temps. I've done 2 fluid changes prior to doing a 3rd fluid/filter change just now. I believe it is good enough for now where it is at on the dipstick. When driving around that fluid is sloshing around on turns, stops, going uphill/downhill. It's almost...

    DIY ATF Drain/Fill

    So at 122F the fluid is between the center rectangle and below the 122F line. Good enough for me. Ran it up to temperature twice and so far no leaks. I will take it for a test drive slowly down the driveway without the plastic bottom cover and then check for leaks before I install the cover.

    CX-5 Transmission: Drain and fill vs flush vs oil pan drop drain/fill?

    With RTV, the pan mating surfaces must be completely oil free and clean. The RTV must be applied to make sure it covers the mating surfaces without any voids. Gaskets are much easier but the gaskets they supply in the kits are usually cheapo gaskets. On my other cars, the factory included a...

    DIY ATF Drain/Fill

    At 122F, the fluid is at the low mark. How much more fluid to bring it to full? I ran out of trans fluid after 5 quarts. I need to get 1 more quart at the Mazda dealer.

    DIY ATF Drain/Fill

    Did my trans fluid and filter on my 2017 CX5 today. Getting that pan off with the factory RTV was a pain. Had to break the seal and then pry it down. The RTV acts like a glue. Then cleaning the pan was another pain. I wish Mazda would just use a reusable gasket with a steel core and outside...

    Switched to 5W-30 from 0W-20

    Is not the OEM Mazda oil made by Idemitsu? If the 5w-30 Idemitsu is on the "thin" side of 5w-30, it still has to be thicker than 0W-20 in order to qualify as 5w-30. Main thing is that it is full synthetic and Idemitsu is a well respected oil manufacturer. I am sure it is a quality oil.
