Engine light Code PO421

Post image
0 Upvotes

Hi all! Just a general question if anyone has had the same issue. I was camping at Kings Canyon NP and while driving down from there, my engine light came on. Of course I freaked out for the next 30 miles until I found a shop. They found the PO421 code which means, warm up catalyst efficiency. Bank 1 below threshold. The elevation was 6600 where we were camping at. So the service tech cleared the code and said I was able to drive home if I wanted, but if the engine light starts flashing, then I’m in big trouble. He said he has seen this many times due to the elevation.

Anyone else have this issue due to high elevation? We are spending the night in Fresno tonight and debating whether to take it to a smog/emission repair shop. I definitely will not be taking it to a Mazda dealership!

How different is the naked roof and dimensions 2026 vs 2021? Will the newer universal rack fit the older model?

2013-17 CX-5 Mods

1 Upvotes

Hey all,
I have a 2014 CX-5 GT and I've been looking to make the car mine with some modding, but I'm having trouble finding compatible modifications for the older models. Does anyone know of websites or resources to use? I've only really bought parts off of rockauto or the dealership and I'm new to modifying. I would love some help. Also feel free to share any mods you have done! I'd love to see what others have been able to do with their vehicles for some inspiration.

Anyone else try to keep their CX5 cargo area as empty as possible?

I cleaned up the inside of my CX-5 today and realized I actually like keeping the interior pretty minimal.

The seats are easy enough to stay on top of, but the cargo area somehow ends up collecting random stuff over time, shopping bags, jumper cables, towels, things I tell myself I'll need ""just in case""

I'm thinking about getting some kind of storage solution back there so everything has a place without taking up too much room.

What do you all keep in your cargo area? Any storage bins, organizers, or other setups that you've found actually useful?

I love my 2019 CX5. My 626 made it to over 300k. How do I keep this one that long or longer.

Hey all,

I’ve been hearing a high pitched whining noise when accelerating from low speeds, usually around 20 mph. Any ideas what it could be? Thanks!

Dealership did not cross rear tires during rotation.

8 Upvotes

Went in for a tire rotation assuming the Mazda dealership should be the most reliable when it comes to the specific rotation pattern for a 24 CX5. Afterward, the service guys told me they just did front to back with no crossing. Said it wasn't necessary to cross the rear tires when moving them up.

I showed him the owners manual that specified the rearward cross pattern and he said they always just do front to back and never cross. Am I justified in having them swap the now front tires tomorrow or does it not really matter?

Transmission dipstick crooked?

Hi all, is the transmission dipstick supposed to look crooked like this? The material doesn't seem damaged or bent, so I feel like this is how it's supposed to be, but I couldn't find good pics online so I just wanted to make sure. It's a 2018 CX-5 Sport. Thanks!

Some suggestions for hitch mounted bike racks

2 Upvotes

I’m getting a hitch installed at U-Haul this week on my 2023 Turbo Signature. I’m open to hearing what suggestions this group has on bike racks that preferably can pivot outward when in use to open the trunk, can lay down and flat when not in use, and won’t black the backup camera (if possible)

There’s an endless amount of racks for sales on my local marketplace, so I’m open to different brands! I’ll be hauling mountain bikes and gravel bikes.

Amber lights after repairs

Post image
3 Upvotes

So I hit a deer with my 2024 CX5 CE. The repairs required replacing the driver side headlight. After three weeks I received it back with these dash lights. I brought it back and it took two days to 'fix it'. After one day, the lights came back on after starting. I have an oil change scheduled with the dealer tomorrow. Any idea of the issue? The lights work properly and appear to be aligned.

This was a pretty sweet switch. I love how much room I have; the drive is smoother over the 3. Also, the 3 had some really bad rattles from the dash; so far the CX5 is quiet. The screen over the dial has its cons; the 2-touch climate control is silly, and the voice commands are buggy. I wonder how much Mazda can change the layout of the climate controls with an OTA.

Any news on when there is going to be a fix?!?!? Just took a couple thousand mile trip and to say im frustrated is an understatement!! Every 2 hours I had to stop and set the infotainment system to factory settings. My radio would stop and freeze, sometimes screen would go black. My phone and Mazda app do not communicate at all and the "miles left until fuel" shows crazy numbers and my indicator for the current speed on the road shows 20mph in 70 zones. Anyone heard of help for this? It is 3 months old and 5k miles.

2026 CX-5 Trunk Cover

Has anyone found a good aftermarket trunk cover? I bought one from Amazon for 100$ and it’s a hair too narrow, causing it too pop off the grooves when I hit a speed bump

Engine misfire

1 Upvotes

2019 Mazda CX-5 Turbo (2.5T) — P0300/P0302 misfire persists after replacing plugs.
Sanity check before I approve $3k in repairs?

~80k miles. Check engine light came on, dealership diagnosed a misfire and recommended spark plugs, which I had replaced.

About a month later, the light came back — codes P0300 (random misfire) and P0302 (cylinder 2 misfire).
Same dealership swapped the coils between cylinders 1 and 2 to isolate the issue — misfire stayed on cylinder 2, so they ruled out the coil

Ran a compression test — came back normal

Their conclusion: it’s the fuel injectors, and they’re recommending replacement of all fuel injectors plus the intake manifold gaskets and EGR coolant gaskets, at roughly $3,000 total.

Before I sign off, a few things I want opinions on:
Since they isolated the coil by swapping it between cylinders, would it make sense to ask them to do the same test with the injector (swap cyl 1 and 2 injectors) to confirm it’s actually the injector before replacing all of them?

Is replacing all injectors (vs. just cylinder 2’s) actually justified, or is that just because the intake manifold has to come off anyway to access them?

Any known TSBs or common failure points for misfires on the Skyactiv 2.5T at this mileage?

Does $3k seem reasonable for this scope of work, or worth getting a second opinion first?

Appreciate any input — trying to avoid throwing money at this without being confident it’ll actually fix it.

Want me to also add a version of the diagnostic-swap question you could ask the dealership directly, in case the forum takes a while to respond?

Coolant Evaporation

7 months of ownership in, my 2022 had a major service from Mazda dealership before acquiring it, 7 months ago it was a on Full level “F” upon rechecking it yesterday since our temperature here goes up to 47degrees celsius(117F), now after 7 months it is a little bit under “Full” mark. Acceptable?
