Mazda CX-5 (and other models) Oil Consumption TSB (WTF)

[Glee217]

Lol, I share the sentiment. I'd really push for that master tech to do the work

Yes master tech or senior tech had to redo my solenoid leak as well as diagnosing/replacing struts for popping/creaking noise.

Man if I hear some members that can do the vavle seal replacements for the oil consumption w/o lights/codes I would jump on it since I don’t drive that much but yet again I would wait till the fire dies down since they are probably just starting to be trained on even how to handle this situation let alone on how to replace the valve seals lol

Just had the job done last week on my '21 CX-5 2.5T. Reported oil consumption to them last fall (had the light come on several times), but stupid me I cleared the DTC after topping up, so they didn't see any code and said "all cars use up oil". Yeah, but almost a liter every 5k? Light came back on a few weeks ago, also around 5k since last time; this time they saw the code and did the TSB repair. 2 days in the shop.
FYI, this class action is only for USA VINs it seems - not us Canucks.

This valve stem seal replacement job on the 2.5T isn’t easy even with the special tools designed to eliminate head removal. You can go through the repair steps in the TSB and see how complicated the job is. The TSB also stated that:

“This repair can only be performed by Senior and Master Technicians.”

which also indicates the level of difficulty for the job.

Although I also hate to let a dealer perform such job to my engine. But if I had a 2021 2.5T I won’t hesitate to have this job done right now, as for one I have no choice but to let the Mazda dealer replace these inferior exhaust valve stem seals which for sure will fail in the future. Secondly those Master Tech at Mazda dealers should have enough experience now for this job and chances of screwing things up should be minimum.

wish I would have read this. Took mine in last Wed June 5th, got it the 13th. Gas smell in cabin was strong during idling. Returned it today 14th. Attendant said it's like heart surgery.
I hope a Master Tech is working on it Monday 17th.

Update to all with this issue, see below attachments for direct communication from Mazda to dealers and repair procedures straight from the horses mouth. Print out and present to dealer while smirking and telling them to get busy.

finally it happened, low oil warning in MyMazda app
last oil change at 15k, now it's at 20k
interestingly didn't notice anything on the dash, if there was no phone app I wouldn't know it happened
will go to the dealer on Tue

That is concerning. You had no low oil light on your dash? Was the oil actually low when you checked it? I actually just checked mine a couple of days ago. I am at 28k (3k since my last oil change) and it is still full.

I didn't check the oil level, just dropped it off at the dealer.
And that's correct, there was nothing on the dash.
Oil level is not constant and changes with temperature, car position etc. My guess is that at one point it was low enough for the sensor to trigger sending the alert and possibly triggering the dash light that I didn't notice, but then it went above this threshold due to those factors.
I'm sure that within a month I would get a light on the dash, I don't want to go to that point.

Another thing - I've been using premium gas only the whole 5k since the last oil change, and pushed the pedal harder. Decided to take it to the max and see if that triggers the alert, and there you go
