No but I'm sure the dealer does. Its a brand new car with a warranty. If there is a problem let the dealer fix it.

 

So today my dealership said they have no fix but it should not be an issue. I have owned my Mazda3 hatchback Premium for 6 months and three times this warning has popped up. 11405 miles total on car as I drive a lot for work so battery gets charged good. Reset/recalibrated electronic system and did not help. No software fix they said currently. The only thing I can think of is something running in background after car is off?

 

I also have a M3TH but never encountered this problem I have a dashcam and Radar Detector attached to the front USB 24/7

 

Could you please make a picture of the warning message for my information?

My 2020 model had a flat battery (due to my own mistake), but I never had a warning. I already concluded Mazda does not give such warnings. With a picture I have some prove for the dealers. And maybe it is only from 2021+, still the picture would be helpfull.

 

 

This is by design. It just means the car doesn't like to run electronics without the engine running. Or put differently, if you listen to music, leave the A/C on, etc while the engine is not running, you'll drain your battery and require a jump start, hence the prompt to start your vehicle.

Think of it as a low fuel warning light.

Is that right? I just got the same warning in my car and I had just driven a 10h stretch (going from MD-GA, about 660 miles). I did not leave anything on with the engine not running. I’m not sure why the warning is on and if I should ignore it or not… I wouldn’t like to wake up and see that my battery is dead.

Hi all:

I just bought a 2021 Mazda3 Turbo PP this week. This message pops up after I turn off my car and it goes away by itself. This message also pops up after I start up the car and it goes away by itself. Does anyone encountered this problem before and how you guys fix it?

Thanks

I saw that message after shutting off my 2021 Turbo 3. The doors and trunk were open for about 5-10 minutes while I was installing my phone mount and doing some other things. I also saw this happen to one in the dealer showroom when I opened the door to sit in the car.

I bought a 2021 Mazda 3 premium with the same problem. The dealer exchanged it for another Mazda 3 Premium which now also displayed the same problem. I did not have electronics on using Accessory mode. All I did is park and shut the motor. Clearly, some defect that Mazda needs to address.

 

Did you manage to get to the bottom of the problem? I have just bought a 2021 e skyactiv x 3 HB and keep getting the low battery risk start car warning even when I was charging the battery, it also seems to lose charge from full overnight when turned off, like it's draining away.

 

The BP has way more parasites than the previous gen. Buddies here have addressed this issue w/ a trickle charger like the CTEK MXS 5.0.

I had the same problem just last weekend. I posted about it. I ended up using a trickle charger to get it back up to 12.8 Volts. It was showing low at 12.3. I also did a crank test to ensure it didn’t drop below 10 when I started it. If it does the battery may be bad. Since I trickle charged it, it went away. But Mazda did offer to fix it for me. My guess is the cars sit for a bit before being sold and the battery drops a bit. They should start checking them before delivery in my opinion. Enjoy your new turbo! I know I am.

 

It’s definitely an issue. I too have the same issue with my 2021 M3T - 3 days old. I sat inside the car for 5 min after turning it off with the interior lights on, that’s all it took. Again, not normal. I have a dash cam plugged into the USB but they lose power after 3 min. Computer glitch 100%.

 

SAME. I took it camping 2 weeks after purchase and was an anxious wreck all weekend. It probably drove my neighbors nuts too. I was told there is nothing they can do. I read online that it's because it constantly searches for lock status and it drains the battery. This car just wants to either be driving or locked. There is no in between.

 

I've encountered this issue once as well. Was drying the interior door panels of my 2021 M3 HB when the message pops up. When I started car and let it sit idle for 5 minutes, turned the engine off and the message doesn't go away for about 10-15 seconds. It only went away when I took the car out for a drive. Nothing was running when I had my car's doors opened though. I wonder if the sensors are waiting for the "walkaway lock" to engage during those times and if disabling this feature will rectify the issue. Still this shouldn't be happening at all then I wouldn't feel safe dropping the ride to a car wash.

 

HERE IS THE FIX: When you park your vehicle, PRIOR to shutting off the engine engage the emergency brake by pulling up on the button. I discovered this a couple of weeks ago when attempting to find the problem. The Mazda vehicle manuals state that is the procedure when parking the car, but unfortunately, the dealers thought it may be easier just to tell people to disengage the emergency brake when starting the car. That will enable the car to move after ignition, but not engaging the emergency brake when you park the car will leave the car's computer in gear, so to speak, and drain the battery. After advising my dealer they attempted it and it worked. Mazda is supposed to send out a notice to all dealers. Not sure of the status of that action.

 

Pretty sure I had my emergency brake engaged since I always remember to do that after putting the transmission to park and before shutting off the engine but I'll keep an eye on the emergency brake in the future if the low battery risk warning pops up again.

 

What is an "emergency brake"? Do you guys mean the electronic parking brake?

 

My bad, the electronic parking brake is what I and I believe @M. Sue meant.

 

Pre 2021 models do not have that warning/protection included. I asked the dealer after my 2020 would not start due to an exhausted battery. That case was my fault, so I would have been warned on time.

Could anyone snap a picture with that warning message for me? For reasons

 

 

I'm glad I found this post. I took delivery of my car 3 days ago and was seeing this message. I assumed it was because the dealer allowed the battery to go completely flat. As I write this I had put the car on a battery charger a few hours ago. I'm going to let it slow charge all night.

 

The message isn’t warning you that the battery is dead, it’s more of a warning to close the doors, turn off the lights etc so the battery doesn’t go dead.

I bought 2021 CX-30 and got the issue after drove back home the same day. Now the alert pops up when I just open the driver door without starting it. So have to wait for Mazda to recall it? or software upgrade? The dealer can't do anything now. Will swap it to another one from dealer help? It might have the same issue on all 2021 models.

 

There's really no issue. The way I read the TSB, Mazda was overly cautious with the software programming. I'm thinking there will be a software update down the road.
Are Mazdas able to get over the air updates or is that just for the entertainment system?

I have a brand new Mazda 3 sedan 2021. When i buy It i notice this issue and It persist for some days. I charge the battery and the issue ended for some weeks. Today i open the driver door after 3 days without dirving and i recive the alert again...Is It normal?

 

This isn't normal unless you forgot to lock your car for the past 3 days. Basically this issue is really annoying and I wonder if this can ever be fixed.

 

Also had this "temporary" message occur upon a start-up of my 3 week new '21 M3 Turbo PP.
It happened only once. Should it occur again - I will capture and share a photo of the message - then off to the dealer for warranty work

 

I think the warning is working as designed. I've drained my battery maybe 5-10 times, requiring a jump start while installing various aftermarket products. Every time, the engine would not turn over at all, and then would start and continue to function properly within maybe 5 seconds of being connected to another battery. Although it's only speculation, I was thinking that unlike older cars that would weakly attempt to turn over the engine while having batteries in a partially discharged state, the gen4 has some sort of fail safe that tells the ECU to use the dying battery only for some of the electrical system, but not to attempt sending the remaining juice to the starter to turn over the engine. Thus they added the "Low Battery Risk" warning for immediately before that threshold is met.

That said, having to lock the car to avoid parasitic drain sounds like a bug to me. I almost never lock at home, have my amp set to auto shut off after 15 minutes of inactivity, and have a cam in parking mode, none of which have posed any problems once everything was installed and grounded properly.

 

Mazda has updated the SA for this message:

 

I just got Mazda 3 today 2021 and had same msg pop up about the low Battery risk....what was weird was I noticed the clock on the screen also reset itself to 12.15, I was working inside car cleaning it with door open....when done started car shut off couple times and it kept popping up, but again check your clock on the screen seems car loses power or goes to a sleep mode reset and things get effected like the clock.... Return to dealer service dept three hrs later.. I saw the bulletin posted ..my former Hyundai would put on similar message when using equipment in car when car wasn't on, once started it went away and didn't come back unless doing same thing, this seems to be doing something to electrical when it's triggered, now after driving twenty minutes back to dealer when I shut off car, no warning came on, also dealer has to replace drivers door glass has a.line in it during manufacture process defect.....will post when I hear from dealer

 

My 2021 Mazda 3 Sport has the same annoying issue. This only happens on the 2021 Mazda 3 and CX-30. This is a firmware bug as this doesn't happen on older models than 2021. It is annoying, waste of time, gas, and time to start up your car for 5 - 10 minutes to clear this message only to have it come up again if you open your hatch or doors too many times. Plus NOT environmentally friendly to have to start up and drive to clear this message only for it to show up again a few days later.

The issue is, how do you know this is a real issue or the usual warning message until you are stranded somewhere with a dead battery?!!?? Take out your voltage meter before every drive to measure the voltage on the battery to see if it is real or not? Unacceptable!

I contacted Mazda Canada and they implied this is normal operation and are not looking to fix this "bug", any time soon and that is what it is a "FIRMWARE BUG". It seems once they have your money, they are like every other car manufacturer, They don't care!

If Mazda is going to sweep this under the rug what else are they going to do if any other issue comes along. Not do anything about it? This is not normal. I have contacted them again to find out why they are not going to fix this issue as clearly this is NOT NORMAL and have yet to get a reply.

It's not a waste of time or gas. Just ignore it, the car really isn't in danger of running out of power. When I'm doing things (working in the car or cleaning) I know the message will come up and I ignore it for now. Hopefully, Mazda will do an update that makes it less obnoxious. Many other cars do the same thing, but don't scream at you for 30 seconds.

 

Yea I get that message too. Super annoying as I just got my car so I had to set up a bunch of stuff and it will flag.

 

I also have been getting this message. In my case I usually drive little and always short hops less than 5mins away from home so it makes sense that the message is coming up. That said: I always leave my car plugged into a trickle charger so I know for a fact the battery is NOT drained. This means that the message comes up REGARDLESS of the battery charge level which to me is just a bad design -- from the document it seems like all they do is count the time the CAN bus is awake (i.e. electronics running) with the engine off and when it reaches 30 minutes the alert starts popping up. Now the worst part: in my case the alert keeps popping up every couple of minutes despite the car being locked with the parking break on (which is already unecessary inside my locked garage) -- it should be obvious that this popup is in fact ACCELERATING the battery drainage by turning on display/sound, specially if you have something connected to the USB and/or 12V ports which also turn on for a few minutes when the alert comes up. For my type of 'normal' usage this is absolutely annoying and wasteful to have to 'keep the engine running longer' to prevent the message from coming up.

I was in fact able to get the alert to go away by turning the car on (without driving or removing parking brake) for 15+ minutes (the documents say 5 mins is enough but I wanted to be sure). I think there should be an option to disable this in the software or AT THE VERY LEAST have the battery level measured before showing the annoying popup. If this keeps going on I may end up wiring a button switch to the room fuse so I can 'reset the counter' manually after each trip to prevent the popup from showing up (but then again I have no idea what kinds of problem can arise from that).
