I don't see why it would be too hard for Mazda to turn off this feature because it was something they only added this year. Previous to this the cars didn't do it. Surely just reverse whatever they did?
 
Hi All,

I got this alert in my 600 mile new CX-30 Turbo. I am assuming that based on that Service Alert 005-21 posted that just keeping the car idling with the engine on is enough to clear this issue ? My problem is that my car is kept valet parked for long amounts of time 2-3 weeks at a time. Do I tell the parking attendant to just start my car 5 minutes at a time from time to time ? Seems ridiculous to me.
With mine, just idling it will not clear the alert. It needs driving for a while. However, as my dealer told me, there's no need to worry about the alert, it doesn't mean the battery is actually going to die, it's just warning you that you could be draining it if you continue doing whatever it is you're doing 🤷‍♂️
 
I keep my fob in the car all the time when garaged as my garage is secure and i live where crime is virtually non-existant. I keep the fob in a small faraday key case and can leave it parked for weeks on end (i have another vehicle) , and very rarely (i cannot remember the last time) i got the lo battery alarm. So, not certain, but perhaps the lack of fob/vehicle communication keeps the alarm at bay.
No, this doesn't work. I keep my key in a Faraday pouch and it still does it. Also does it with my spare key which has the communication turned off. Its just working on a timer basis.
 
I'm in the UK and keep getting the battery warning message and beeping. It's not because of the keys because I have turned off the spare and I keep the main one in a faraday bag. What seems to set it off most is when I'm doing something in the car and the door is left open for more than a couple of minutes. This is without having the ignition on and everything is off including interior lights. The dealership have looked at it and said battery is fine and the software update is not applicable to mine because its too new and update was already included on mine from new. They are saying its just a normal feature and that the car is just reminding me that I could be draining power, NOT that my battery is about to die. They said they would ask Mazda if there was a fix, but I never heard anything back, so I guess not. I wouldn't really mind this if just did a couple of beeps, but it goes on for about twenty seconds or so. Also once its gone off it keeps doing it everytime I go into the car until its been driven again. Not the worst problem I guess, but just an annoyance!
