New 2024 cx5 with 4000km. Some questions
Congrats on the new ride - there is a substance which is applied at the factory for purposes of preserving the vehicle from shipping to sale - Im guessing , ---Back n da day ---Car dealers would refer to the odor as "Cosmoline" and it generally was sprayed on the undercarriage, suspension and engine/trans --Ive see new vehicle after 1st drive smoking slightly - and it eventually burns off - The smell is slightly acrid but not like oil --It should go away pretty fast unless you dont warm the car up and take short trips --may take longer --if it persists - dealer - // On the oil level - I would be very surprised to find that a new skyactive engine is burning 1/2 quart of oil at 3000 miles ( 4000km) - I HAVE NOT read the other replies so - Make sure you check the oil under the same conditions each time - I suggest , If you have a garage- check it before start up cold first thing - on a level surface obviously- Then keep checking it periodically throughout the oil change interval - I find that trying to check it at , the gas station after 10-15 minutes still gives a difficult to read result --- so cold / cold - best
The US EPA does not allow that anymore for a few decades.
The reason new engine from those long ago days smoked when first started was primarily the oil in the cylinder during their assembly burn off for the first engine start up and first to reach normal engine temperatures.
This is NOT the case for Mazda engines mainly because of the finish honed used in the cylinders and that they use a extreme low viscosity assembly oil.
I would not suggest that at this point the OP is burning oil. There is no foundation of any evidence to support that that he has posted .
Your suggesting for frequent checking the dipstick is ridicules technically speaking for anything less than several thousand mile. If it using/burning or leaking any noticeable amounts, it would be seen with a check engine light or that early morning stark up when the water vapor is leaving the engine would also have oil in the water. Not carbon which is normal but oil.
Last and this is the most important thing, if any Mazda is still under warranty and there are unexplained ANYTHING the owner should go to Mazda asap and at least get it looked at my the service department. Your input is not only valuable but could save an owner from having a breakdown on the road because they failed to have a professional; look at their concern !
So I took the CX-5 in to the dealer for the 1st oil change. Complained about losing oil (they brushed it off). I'm hoping it doesn't happen with this oil change interval. All I can tell you is that it's parked in the same spot every night, level, and over the 6 months of owning it, checking it cold before starting it up has shown lower amounts of oil. To me, that is a leak or consumption, of which they said there was none. I have done this for all me cars (including mazdas) and I have never seen drop in oil level on the dipstick.
I also gave them the TSB for the rough shifting from mazda North America (posted in a previous post). They said it wasn't applicable to Canada, only the US, although it clearly states right on it codes for the fix for US, Canada, and Mexico...so that isn';t finished -I will be getting them to look at it again. She did apologize, so I think they knew they were wrong. - but it was now a waste of my time having to go back and deal with it again.
I also pointed out an issue I have just seen as well in the last few months (quite cold here in Eastern Canada). From a cold start and just sitting in the driveway, I can see my temp gauge climb fairly fast to almost out of the blue region in a minute or two, then it falls right back down to horizontal (starting location), then climbs normally up when driving to just under 100, maybe 95 (but takes forever). I've never seen a fluctuation on a temp gauge like that. I have read that isn't normal, and I think the dealership misunderstood me when explaining it. I just haven't seen anything like that before. Anyone here notice anything like that?
Now obviously I'm not a mechanic, but of all the vehicles I have owned (including mazdas), I have never seen my oil level drop. I do not like the fact they said it was where it should be and just dismissed what I said, and yes, it's still in between the dots, but it has steadily been going down under the same checking conditions.
All in all, pretty frustrating dealer experience. I am giving it a couple of days before going back with the TSB again - it's just a reprogramming that takes 20 minutes according to the TSB.
Cheers

Your dealer could be more helpful, eh? Give the oil situation some time. If the same thing happens at the next oil change, you will have the evidence you need to push this farther. It would not kill them to crawl around in the engine space and look for some oil residue, would it? Good luck.

You also may have (only IMHO) read comprehensive deficiency as well. You seem not to have read that TSB very well?

No he wont.... not physically having the vehicle to actually make basic observations? There are some obvious flaws in his post!
It is not as easy as crawling around the engine and under chassis area as say pre year 2000 manufactured vehicles .

To do it properly is about an hour and several parts need to be removed.

His dealer from what I am reading so far is BEING HELPFUL. But we only know the OPs side. Maybe he should post his service orders up so we can see all the information and other supportive information instead of the one sided story.

She actually apologized, so I'm pretty sure they were at fault. So no, I don't find that helpful
As to a one sided story, I asked them to look at the tsb as I was experiencing the issue that was described in it... They said not applicable in Canada then apologized when I physically pointed out the fix in Canada. So not sure what else to say about that..
And yeah I'm not a mechanic, hence trying to get some help in this forum. If you measured your oil the same way everytime on a over night cold engine and saw less and less oil on the dipstick, what would you think? What else could it be besides consumption or a leak? I'm just hoping it doesn't happen with this oil change.
I would drop the plastic covers and inspect for a small oil leak not seen without that service.
Then I would scan the ECU in all 3 areas as well my counters to see if the engine was burning the oil before it killed my CAT or did other engine damage.
I may do a compression check bot dry and wet followed up by a leak down test
Ands maybe a coolant test.
The TSB was not for you even as a consumer and was written and intended for the Mazda service department use only. As I said had you read and actually understood all the information and not pick and choose what you want . They have been used in a couple of lawsuits that presented by owners as supportive documentation and tossed out because of the information direct on each page toward consumer use. So keep that in mind!
Forums no matter what the platform members can't help you really except either rally to your side or post simple facts and truths. And the FACTS are if it is under WARRANTY your issues should only be between you and the dealership and MAZDA corp!
You saying what was said by the dealership is often not exactly what was the on the final service invoice.

I can state how many customers each year I get like you; think they know more than they really do about several aspect of their vehcle and service-related information they find on the internet. LOL
In the first place there is no reason to suspect you are losing oil from what you posted ... why because either a leak is found or there are issues that will be reported by the ECU. w

I'm not saying I think I know more about my vehicle... I've brought in TSBs to this dealer before for issues in the past for my mazda3 and they had no problem performing them.
Anyway, you obviously know a hell of a lot more about Mazdas than I do, that's not up for debate at all, but you don't have to try to belittle people when they are trying to get to the bottom of some issues they are having with their newly purchased vehicles.

There must be a language translation problem???
I never said the TSB was not anything except for a Mazda dealership and specifically as it states (see picture) If you are not as described in that disclaimer then you are not qualified to make any assumptions. PEROD> You can show a service department the TSB but after that it is THEM NOT YOU who decides the service action they determine to take regarding an individuals POSIBLE service related issue.
As for the STORY there are 2 sides at this point your as you interpreted things and the service department actual documentation that you are reluctant to post . I still gotten wonder why that is?
DUDE their or 2 members on this forum experienced in reading and understanding everything on a MAZDA TSB and you are not one of the 2.
At this point I can see that this thread is nothing more than you venting not getting your way as you deem it should be. Who are you? LOL Burn your bridges with dealership as I see it is beginning, and dealership as will the auto manufacture can and will drag their feet to help you.

Look up the word MAY. Then look up what that implies or suggests even in your country when it comes to using it legally
Many TSB start off in the description of complaints as :
DESCRIPTION Some customers may complain..........
In your posted TSB did you read this first?
REPAIR PROCEDURE • 1. Verify the customer concern.
Your was not verified at least as I read what you posted but without that service invoice who knows what missed when you missed these things on the TSB? lol
How do you really expect help or advise when you debate and argue down some of the better information to attempt to at least enlighten you a little more about what may or may not be a problem?
