Hi all! I have owned my brand new Mazda cx30 for 1 week. However, on day two, I drove it home 400km post purchase. After half an hour in my garage, I started getting a flashing warning and beeping on my dash indicating that I was at risk of battery failure, start the engine! My local dealer kept the car over night and recharged the battery (even though I did not feel this would help After driving it that day for over 4 hours) . All was well for 4 days. I was so relieved........This morning I got up and went to start the car. Same message appeared😓 along with beeping for about 10 seconds. I decided to go for a 20 minute drive, reset everything to factory settings. it seems ok for now.3.5 hours later. This is so disappointing as you buy a new car NOT to have these issues occur. I did leave it unlocked in my garage last night with the fob in the house, not the car. Any suggestions? This can not be simply a flat battery issue in a brand new car. just a side note, i noticed that it did not always automatically lock when I walked away From the car.

Could you tell us what type of CX-30 you have (X, G or D) and if you added an accessory that uses power such as dash cam, aftermarket wireless charger etc.
Mazda engineers from Mazda Spain/importer or from the dealership? And that you have a 2021 model does not always mean the modules contain the latest software versions available. Was the welcome light function checked, see flat battery ? Mine was activated which should not be the case for Europe as that function is not supported at all in Europe.
Yes..they change the battery with a new one specially for the e-skyactiv-x but the same problem. I mean with the engineers froma Mazda Spain and yesterday directly from Japon they colected all the data.
just got back from my local dealer this afternoon as they contacted me a few days ago to ask me to bring in my CX-30 to have an update on various modules to prevent any excessive battery draw when the vehicle is "asleep". This was a TSB not a recall, no charge and they even washed my car after. It took about half-hour.
Good news. I also have an appointment in few weeks for, I hope, the same TSB.
Hopefully, this will solve the battery issues.
The problem occurs only when you use the sounds system on acc mode (no engine). Other than that, I'm quite satisfied with my car.

Below is a link to my post concerning the SSPC5 Update that was done (along with SSPC4, Bose speaker issue). On of the three things addressed concerns battery drain.

SSPC4 and SSPC5 Recall and Special Program information
I now have two items listed on the MyMazda app, SSPC4 "CX-30 Bose Speaker noise" and SSPC5 "Reprogram Control Unit". Information has been posted here for the Bose speaker issue, but I haven't found any information on the SSPC5 Reprogram Control Unit issue. Does anyone have any information for...

Sat in the car for about 15 minutes with just the radio on, waiting for the wife. Car wouldn’t start when she came back, flat battery.
Any ‘ordinary’ car could have the headlights, radio, & charging phones on for longer than that without any adverse effects. What could have caused such a massive drain on the battery in such a short time?

If you have a MY2021 after some time in acc mode it warns you to turn on the engine and if you don't it shuts down automatically, in order to prevent the battery from completely draining.
Today i had my two front windows tinted, the car was in acc mode for about 30 minutes with radio playing and navi showing info, the warning didn't appear and car started normally.
I haven't really figured out when the low voltage message appears, I've seen it once after a 3 day inactivity but in my case i believe that due to low mileage my battery hasn't completely charged.
This is a real problem with this car. I have an appointment with the dealer for a software update and I hope this will adress the battery issues. I will let you know when it's done.
Took mine straight to the dealer’s after Mazda Rescue came out & jump started it, they can keep it ‘till they get it sorted.
It must be something with a very heavy current draw to deplete the battery that quick. When it was trying to start, there was a lot of clicking & clonking going on under the floor. Possibly something to do with the electric parking brake?
Regarging the electric parking brake, I can hear mine but a very little noise. For the first issue, many poeple had this problem and Mazda is probably working hard to solve it. Just listening the music required to operate many electronics components and drain alot of juice apparently. I have forced my dealer the change the battery, just to elliminate that possible cause. I have also questionned Mazda by email many weeks ago and I still wait for a reply.
