You need to be more aggressive. They successfully broke you. My wife's car I left at the dealer for a month for them to fix a noise and leak when under warranty. I told them I didn't pay for a broken car. I had a free loaner the whole time.
Thanks for finding that. I'd bet there actually is a 'solution' but it would cost Mazda too much money to implement it.Mazda has no solution as stated: https://static.nhtsa.gov/odi/tsbs/2022/MC-10206940-0001.pdf
Have nothing plugged into USB outlets. See if it makes a difference.
As a follow up to my post, I have multiple vehicles and sometimes do not drive my cx-30 for a week (or two). I have also left a spare phone plugged into one of the usb ports for several days (I don't know if it tries to charge the phone when the car is off) and I have never had issues with low battery or any messages about the battery.I have a 2020 cx-30 (preferred trim fwd) but I have never had any kind of battery warning. I have had the doors open while I clean the interior quite a few times.
In the thread linked in first post, someone said the dealer had found a shorted relay and after it was replaced, he had no more issues.
Now the rain sensor in my cx-30 has never worked, I can see that the sensor is not adhered to the windshield correctly. I just haven't bothered taking it in for that yet. I need to do that before warranty is up.
I did find a loose fuse in the dash fusebox soon after buying it, but could not find an empty spot for it there or in the fusebox under the hood, so I assume it is a spare. Maybe that unused fuse is preventing my battery drain lol.
Edit: bolded because for the rest of the thread (on cx-30talk.com) no one commented on that possible fix. Seems plausible to me that a bad batch of relays got into some cars, and caused a battery drain?
Did you measure battery voltage???I charged her battery and the next day it gave the warning again.... when I put it back on the trickle charger it took several hours to fully charge. While this is not scientific it does tell me the battery is draining. I'm not surprised with all the 'warnings' on the vehicle (and most modern cars). Mazda should figure out the problem (it's probably software related....whatever that means) and fix it.
No...I don't have access to the car right now.Did you measure battery voltage???
That's one of the reasons I posted it on this sight. When people realize there is an issue and question the dealer before purchasing...maybe the dealer network will start complaining about lost sales forcing a solution. Mazda knows there's an issue but refuse to fix it (as the TSB in post #25 mentions).That's a Premium Japanese car electrical problem.
it sounds like Mazda COULD do a software fix for it, if they had the motivation. Maybe if enough people complain to Mazda USA corporate, they would take action.
Too bad this issue doesn't appear with their press cars, because if enough of the press complains about it, they would also fix it.
Since Mazda likes to advertise on Social Media.... get a video and post it on social media. If enough owners do it, thus the youtube viewers see it... and Mazda's no-solution for it... it would motivate Mazda to actually address it.
This site only reaches a limited audience.No...I don't have access to the car right now.

Agreed, we need to know voltages.If and when you park it,get a voltage,wait a day,repeat.You need a paper trail for the dealer.If the light comes on,a reading.If you don't have it on paper,a dealer will not take you seriousDid you measure battery voltage???
