Normal CX-5 engine noise? Just noticed yesterday

:
2019 Cx-5 sport
Hey all, 2019 CX-5 sport with 2,300 miles on it, bought brand new 2 years ago.

Just noticed this ticking noise while driving through parking lot, and thought,
is that my CX-5 making that noise? Got home, checked yesterday and today and
the noise is still there. I don't remember this noise when I bought the vehicle, a loud ticking and rattling sound.

Will be taking it to local dealer Monday, but I've taken it for other noises over the past couple of years and both lead mechanics that I've talked to say 'they all do that' and maybe I just never noticed this noise before..?

Thanks for any info.
Joe

Ok, update, went back to dealer, talked to sales lady that sold me the cx5...Told her about the ticking noise and was wondering if she'd let me listen to a new cx5 with hood up. She said no problem. She started up a 2021 sport and I had mine a few feet away...My cx5 was warmed up, the 2021 sport was a cold start.

We both thought my cx5 was a little louder, but the new 2021 ticking was coming from the same area as mine. So, guess, it's just the noisy fuel injectors like several mentioned above.

Thanks for all the help and information.

A full 5L jug will fill my 16.5 2.0L to the full mark as it is a smaller engine.
The oil capacity with oil filter replacement from Mazda specs for 2.0L is 4.4 US quarts / 4.2 L. You use 5.28 qt / 5L jug of oil to reach the Full mark, which means you need additional 0.8 L / 0.88 qt more than Mazda stated, a 20% difference from the spec.

guess mine sounds like both those videos myfirstmazda posted..
except his sounds louder than mine , considering he's about
5'-6' away and I was about 2-3' away ... plus guess it depends on
how good your microphone is on cell phone

5.5 qts to be at the full mark with sport ... ok , good to know ...
So, I'd probably just put in 5 qts...

Just a note, I've never floored this vehicle until monday , so my rocker
arm could have fallen off over the past 2 years.... but the question is ,
once you do the 'italian tune-up' can't the rocker arm fall off then and
there ? I've had the pcm update on july 10 2019 and bought the cx5 on

Sorry, I think I meant 5 qt. Jug, not 5L.

Yes, there’re too many variables to diagnose the car problems online. Since your 2019 CX-5 Sport has only 2,300 miles, chances having any problems are minimum. Your short video when you took the recording was too close to the engine top, which definitely amplified the fuel injector’s ticking noise. You still can listen to the engine sound from another CX-5 to verify next time you visit the dealership.

For your 2.5L, you want to put in 5.2 quarts first if you want the oil level to be at the Max / Full mark of the dipstick. You can add a bit more if the oil level is not high enough. For most 2.5L’s, 5.5 quarts would be too much unless you drain you oil overnight with the CX-5 in proper angle. 5 quarts is fine as long as you understand the oil level won’t be at the Max / Full mark. Check your oil level often to understand if you engine is burning any oil.

If you decide to DIY on oil change, I’d suggest to use OEM oil filter. Strangely Mazda offers 2 lines of OEM maintenance parts (again, different from everybody else). I wouldn’t use OEM “Value Products” MV oil filter just to save a couple of bucks. Search the forum and there’re plenty of info on this matter.

Just a note, I've never floored this vehicle until monday , so my rocker
arm could have fallen off over the past 2 years.... but the question is ,

So far nobody has reported rocker arms have fallen after the recall, so it’s safe to say it shouldn’t happen to you after you did the the first WOT test. You can always try another WOT test keeping the RPM at 5,500 for 15 ~ 20 seconds in low gear at a safe environment to verify. In the meantime you did another “Italian tune-up” and burned some carbon deposits off. ;)

It sounds like you're asking if keeping the vehicle floored like you did could be something more likely to detach the rocker arm, and are concerned about doing it. The official statement from Mazda is that the detached rocker arm issue was identified to occur during the transition from deactivation (of 2 cylinders) to full cylinder operation.

No one here knows for certain if that's the complete and honest story, but it's all we have right now. So if you accept what they wrote, then it's important to note that they also made no mention of vehicle speed or acceleration. This would lead one to believe that pushing the vehicle like you did does not make it any more likely to detach a rocker arm, than any other (possible) transition out of CD.

Any modern engine should be perfectly capable of being pushed as you did, repeatedly over and over again. And as yrwei52 mentioned above, there have so far been no reports of a detached rocker arm on a CD vehicle with the recall computer update in place. So my advice is to continue doing these Italian tune-ups periodically, always in a safe driving environment of course. We're not expecting any problems, but if a rocker arm ever does unexpectedly detach, you certainly want that to happen while your vehicle is still under warranty.

I was thinking of Unobtanium from this post. He has a 2.5L.
New to Mazda
He has a 2.5T which has an official capacity of 5.1 quarts with oil filter replacement. Unobtanium says his 2.5T needs 5 quarts but many others say the 2.5T needs 5.5 quarts to get to the Max mark.

I had mine above 5K today for about 4 seconds, merging onto the highway in normal mode. It is fun. It can't hurt the engine. Like yrwei52 says, we don't really know what the exact condition was to throw the rocker. Reving the engine under load without going into limp mode proves that the rockers are in place, the rocker wouldn't be dislodged driving this way working all 4 cylinders.

I was reading this thread and it seems to be the ticking is attributed to the cylinder deactivation. In another forum, there was a thread on ticking that was high pressure fuel line bracket. Just a shot in the dark....

High Pressure Fuel Line Bracket
No, not at all. I pointed out that OP’s ticking noise is different from HLA issue related to CD, and the ticking noise resembles more to high-pressure fuel injectors in post #2 and #8. And the head mechanic at OP’s Mazda dealer confirmed it in post #12.

The fluid capacities in owner’s manual for Mazda CX-5 are mostly inaccurate as those are “approximate” quantities. The manual says 4.8 quarts on engine oil replacement with oil filter for 2.5L. But it actually needs 5.2 ~ 5.3 quarts to reach the Full / Max mark on dipstick. Front transfer case is correct at 0.45 quart. The rear differential requires ~0.75 quart but the manual says 0.45 / 0.37 quarts on gen-1 / gen-2 CX-5 respectively. The actual capacity of the rear differential is 66% larger than given capacity on specs!

Yes these inconsistencies on “approximate” fluid capacity by Mazda caught me by surprise too, as the CX-5 is my first Mazda and I’ve never experienced something like this from other cars I’ve owned.

Giving a range instead of a single value on torque specs in Mazda’s workshop manuals is another “different-from-everybody-else” thing bothers me.


Yes, anything is possible even if it’s as simple as an oil change by the car dealer nowadays.


5.4 ~ 5.5 quarts.


Yes, do that to verify the ticking noise by comparison.
I think your numbers to get to the MAX line on the 2.5 NA are too high. 5qts gets me right to the top marker (maybe a smidge over) on my Mazda 6

If you search the forum 99% say 5 quarts get them to about ⅛ ~ ¼ below the Full / Max mark of the dipstick on 2.5L. It really depends on how long you drain the old oil, and how level the CX-5 is while draining the oil. There’re plenty of oil can’t be drained out from the oil pan if the CX-5 is perfectly leveled. If you use a pair of standard ramps to make the front raised high, more oil will be drained out from the drain hole located on the back side of the oil pan.

I myself have done oil change 8 times on my 2016 CX-5 2.5L, it always needs 5.2 ~ 5.25 quarts to make the oil level reaching the Full mark. I use a pair of self-made 2-layer 2X10’s to raise the front for about 3”.

The night I got my car from the dealer, the oil was at the full mark. And for my first oil change I put in 5 quarts and over time kept adding oil little by little to get to that full mark. And for me it takes 5 quarts and 425cc. My ramps raise the front of my car about 5 inches. And yes if the car is level not as much oil comes out. And if one uses a quick drain not as much oil comes out.

yrwei52 .. is that pressure treated wood ? or just regular pine...

I was thinking about buying a set of ramps from amazon for $40..
for next time need to change oil...
but those wood ramps look good and 1/3 the price... ( just a bit of labor )

It’s regular pine but those 2X10’s, or all construction materials, are getting really expensive nowadays.

I use these self-made ramps not for saving money, but mainly for minimum rise to my BMW which has longitudinal mounted I6 engine and standard high ramps will affect complete oil drain.
