Update, long story and poll for comicly ironic circumstances: WAIT FOR ENDING!
Brought my 2021 CX-5 Sig with 14k miles in to the dealer to have the stem seals replaced along with a few other issues to be fixed( brake click, CMU software update, dead battery) and of course get a call that they cant do the stem seals because there is no light on and no code stored, even though I clearly provided them the info regarding me needing to add oil between changes, along with the class action settlement card. This is where the fun began. I said no, you are required to do it regardless to which the service advisor stated that the tech said he found my oil to be "overfull" ( absolute BS) and that they need to do an oil change and an consumption test first before they can proceed. I said, I don't know what you are talking about and why you are saying my oil is overfull and I want to talk to the service manager. Mind you, I have NEVER EVER put more oil in than the top hole on the dipstick checking the oil level properly about 10 times during changes. Now, they know me from the last time I was there with my CX-9 that had many issues and that I am very particular about my vehicles and the way I take care of them and are involved in their diagnosis and repairs. I'm not an idiot and know how to put oil in to the proper level. Anyway, I speak to the service manager who I dislike from the last time, and I lay down the law with her and deny what the service writer is telling me. She keeps talking like a broken record about not being able to do it without this or that and what the tech said about my oil level ( which she obviously did not verify herself by looking at my dipstick). I told her I'm going to call Mazda and open up a case if they don't comply and that the tech needs to follow the flow chart and dealer email sent by Mazda as of 5/20/2024 which I provided to the service writer. She has the audacity to tell me she is trying to help me and they don't need my papers etc etc. She asks me why can't they do an oil consumption test first and what is the reason why I'm objecting to it. I sternly explained the damage burning oil can do (like I have to freaking explain this concept to a service MANAGER?!) and I'm not driving another mile with an engine that has defective valve stem seals causing oil burning which is damaging my engine and many other components over time which I will be on the hook for long after the warranty is expired.
She then replied that she will call Mazda and get back to me. I replied, good and I have pictures of my dipsticks from my oil changes showing proof the low level as well and me having to add oil (giving her the idea not to screw with me).
I don't hear from them for 4 days. On the fifth day I get a call saying they are replacing my stem seals ( oh you don't say) and it will be several more days till ready.
Get the call days later that its all finished and to come pickup. Gladly. Get to ther dealer and go over the paperwork and see that 1) the tech wrote that my oil was overfilled by 1/4 quart. 2) they performed an oil change with full synthetic and a Mazda value line MV filter. Now, I never asked for this and never wanted it being that I had done an oil change only 2k miles prior using ultra platinum oil and Oem Mazda Tokyo Roki Made in Japan filter. That pissed me off but I let it go and figured I'll just change it after a couple thousand miles.
Now, here is the part you won't believe. I got home and decided to check out their work under the hood and make sure they didn't screw anything up. This included me pulling the dipstick to see if they really changed the oil. Well guess $&$#@ what. THEY overfilled the oil by HALF a quart above the top hole. Now I'm really really PO'd. Can you believe it? After trying to tell me that I did something ridiculous that never happened, THEY do the exact same thing but for real and worse!
Long story short, what would you do at this point? Picture of dipstick attached showing overfill
