Got no idea how to add to that table, but mine’s gone back to the dealership again today for this.
Drove it forward a few feet to give it a good clean inside & out, probably an hour start to finish. It started fine when I moved it back again but this morning it was just ‘clicking & clunking’ when my wife tried to start it. Called out Mazda Assist who confirmed the dead battery & recharged it. He told me it was software, needed an update - again. (12,000 miles service was done only last week). Then he told me the start button had failed, so it had to go back to the dealership.

Terrible. So sorry to hear it. I wonder when is Mazda actually going to understand and acknowledge that they have serious problems with 12V battery power management on MHEV vehicles?

 

[Glencraig]

I know there are many other threads on here regarding flat batteries, but I've just seen a Bluetooth battery monitor on Amazon for about £27. There's an app for your phone which will give you an alert if the battery falls below a certain threshold.
Has anyone else tried these?

Mine has been back in the workshop at least 3 times before for this.
I dread to think what it would’ve cost me if it hadn’t been under warranty still.

Just got it back again today, no faults found apparently.
I did manage to get a chat with the technician though and discussed the ’battery problem’ with him for about 10 minutes or so. He did more or less acknowledge that the earlier models do have a bit of a history with this, but the newer ones don’t. Mazda do apparently get informed each time any of the main dealers or Mazda Assist report it, and he seemed to think that there would be another update coming out to bring the older models up to the same software spec as the newer ones.

Car battery was dead yesterday and couldn't get the engine hood open due to frozen ice at 25 deg F. No matter how many times I tried.

Today, the car is completely dead and I could not unlock the door with key fob so I used the built in key in the fob to manually open the door. I took boiling hot water in a pot and poured it over the edge of the hood and was able to open it. I plugged in my NOCO Boost GB40 to jump start it. Tried 5 times before the NOCO conked out on me. It didn't work. The battery was completely dead with little voltage.

Called a friend to help me boost with his car and my heavy duty booster cables. My CX-30 started after 5-10 minutes of him revving his engine.

Again, "over the top electronics" coupled with freezing weather doesn't go well with our batteries.

1. Date: February 6, 2022. New York City
2. Failed to start
3. 2021 CX-30 Premium AWD
4. No dealer involved. Got a boost from a friend.
5. I am unaware of any software updates to my car

 

[Glencraig]

Here’s a screenshot of my battery monitor over the last week. The dips represent each start, followed by a sustained peak while the engine’s running. Every time the car’s parked, the voltage gradually declines hour by hour. So far it hasn’t been parked long enough to see if it drops below 12v, and I don’t really want to sit there with the radio on for half an hour just to see if it drops too low to start again.

This is another shot showing just one day. You can see quite clearly where I opened & closed the boot, started the engine and drove for about an hour. The voltage then drops quite dramatically until I walk away & the car locks itself, it then slowly declines for the rest of the day.

 

[chargerfan4444]

I have a 2021 CX-30 Turbo Premium Plus and was getting the 12V error. I wish I could thank the person who gave the solution but it works:

Put it in park. Lift up to engage the parking brake. Shut it off. The key is to engage the parking brake before shutting it off.

I’ve not seen the error since . . .

Thank you Peter--on your comment that SU fixed your car. Can you provide details on that SU you are talking about? Is there a way we can tell in our vehicles if we have or need that software update? Just yesterday--I read in FB an entry from a lady that found her car dead the next day after normally using her car--she, unbeknownst to her--is thinking because she left the windows down a little. It is interesting how our minds work and start thinking on our own what it is may be causing our trouble... I am guessing she was not able to hear nor see the dash warning so that she could --as the warning suggests-- Start her car for a little while to recharge the battery. I guess the more important aspect from what you are sharing with us is the mysterious "reset" action starting the engine does--to clear that warning from keep coming on.

John et al,

I did continue having the warning, when I was washing my car this past Saturday----and BTW--This warning is not included in all the possible warnings from the owners manual ( I was able to find it) ---Also, just happen to read something quite interesting--it happenned yesterday--as I read a lady's posting from FB--One of my many groups I now belong to. She said that, because she locked her car the day before but left the windows down a little--because it was too hot. When she tried to start her car the next day--it was DEAD completely. There is a sensor called Intrussion Sensor--and according to the manual--even wind can trigger it--Really? And are in fact recommending us not to lock our cars with windows down a little---go figure.
So, they are also telling us how to disable it. My question---How do we know if our car has these sensors?

 

[2021cx30turbo]

I have 2021 Mazda CX30 turbo purchased 1 year and 6months to date, here in the US. Purchased brand new with less than 50 miles on it. It currently has 23,000 miles.

1. Date: November 2022. USA.
2. Car: 2021 CX-30 Turbo
3. After accidentally leaving hazard lights on for several hours in a parking lot, car failed to start with flashing error messages- "Low Battery Risk. Start Vehicle to Charge 12V Battery," "Safety and Driver Support Systems Partially Disabled. Drive Safely," and "Engine Malfunction. Have the Vehicle Inspected."
4. Mazda Roadside Assistance was called and they sent somebody to jumpstart the car. Chemical burnt smell immediately after car was jumpstarted. Car stalled at maximum speed of 9mph even when flooring the gas pedal and had the car jolting/shaking. Waited for 40minutes and restarted car at least 3 times before car was able to accelerate and jolting/shaking improved. Remaining error message- "Engine Malfunction. Have the Vehicle Inspected" with engine light still on.
5. Car dealership saying electronics might be fried by dash camera that was professionally installed 1 month ago with no issues. Dash camera installer denying anything went wrong with installation. Car dealership technician stated he tried calling dash cam installer to talk but installer sent phone records showing proof he did not get a call from them. Car dealer stating this is not "warrantable" repair.
6. This is an ongoing issue. Car is still at the dealership.

Besides this current problem, I have been having trouble with repeated change oil warning light coming on months and thousands of miles earlier than when its due. Change oil warning light started going off 2 months into purchasing the car with about 2,000miles on it.

I also have a recurring "Low Tire Pressure. Inflate Tire(s) to Specified Pressure" that will intermittently go off and on through out my entire 1.5 years of owning the vehicle despite the tire pressure gauges showing the almost the same psi's on all my tires.

Also, I have been having issues with the front windshield condensation making visibility a safety issue. A little over a year into having the car, I have the dealership replace the wipers but visibility remains an issue.



Please advise.

Flat Battery!! I'm fed up with this! I cannot rely on it at all, drive somewhere, park up, come back to the car – won’t start! I then have to rely on a Good Samaritan who can let me attach jump leads. This car has only covered 18k miles, and I bought it from a main dealer (used, one prev owner) in November. Five times I’ve had to use jump leads, wouldn’t even start on the dealers forecourt the day I bought it. Every time it has failed I’ve had to charge it with a smart-charger.

When we had some snow the other day, I had to visit the doctors surgery, I’ve got bronchitis and supposed to be indoors, wife not well (hence being at the doctors) so she went in whilst I sat in the car park for 15 minutes. Chucking it down with snow, then the bloody car won’t start, so had to find someone to allow me to connect some leads; now imagine this, in the snow, bitter cold, I’m in my 70s with a chest infection and supposed to stay in the warm & dry, and I’m in a blizzard trying to start a modern car. No point in calling Mazda assist as they most likely would not be able to reach me for several hours due to the snow.

After the above incident, got back home and put it back on charge, left it charging for 26 hours. After that time the display showed 70% charged and still charging at 13.6 volts. I then carried out a specific gravity test with a hydrometer, leaving me with 4 cells @ 75%, 1 @ 70% and one at < 10%. That suggests the battery is goosed.

Contact Mazda, they advise me to book an investigation with my local dealership as is still under warranty. Dealership not happy to accept my results and insisted they must do their own battery check and forward the findings to Mazda who will then decide - yeah right! After being stranded several times, I stated that’s unacceptable and unless a replacement battery is fitted, I will not be leaving their premises. So they’ve decided to replace battery (for now) and test mine in the workshop. Apparently if they find no fault then they’ll want me to bring the car back and leave for 3 days. I had a feeling that would then mean they might try to put the old battery goes back in the car - that ain’t gonna happen!

According to the technician just starting the car and leaving on idle the alternator doesn’t charge the battery whatsoever and it would entail at least a 20 minute drive to replace the drainage from initial start-up. I thought these things were “green” and trying to save the planet? I think he was trying to say battery drain will be incremental unless I go for a run. After having a Mazda 2 for 12 years, and is still part of the family, and it has only done around 30k and had two CX-5s beforehand (each for 5 years) none of those have ever let me down. The last time I had a car with a flat battery was in the 1970s on a MkII Cortina.

Will update.

Hi Alex. I feel your pain. Had similar problems. Car was completely dead one morning. Battery completely flat. After recovery to the Mazda dealer they replaced the battery.

What I have learned is when the car is unlocked it puts a constant 6amp draw on the battery, regardless of anything being on. You said you waited at the doctors sat in your car in the snow. Even without the radio on, no engine running, this will drain the battery! If you hoover out your car (assuming you still have it) because the car is unlocked this will drain the battery.

Get yourself a Faraday pouch for the key fobs. Try not to leave the car unlocked for too long before starting the engine.

Good luck!
Stu

I guess we need to put it all into perspective. It appears that the low battery risk warning and actual instances of flat 12V battery are not closely related. Therefore, I think the log with issues related to the low battery risk warning should be specific to 2021 generation of CX-30 and, perhaps, a separate log is required for rapid battery discharge and flat battery events.

The 2019-2020 generation of Mazda MHEV platform had completely different problems with the 12V drain and these were eventually addressed by software updates. "LOW BATTERY RISK. START VEHICLE TO CHARGE 12V BATTERY" warning was a terrible attempt by Mazda to address battery power management issues in 2021 models through social engineering rather than a proper technical solution. Apparently, they had so many Mazda Roadside Assistance callouts related to flat 12V batteries on 2019-2020 models (costing them a lot of money) that they decided to scare owners into submission by generating this absolutely useless, misleading and false warning, which has no relation to the actual state of charge of the battery whatsoever. It is simply generated by Mazda when the vehicle network awake time reaches 30 cumulative minutes without the engine running. The irony is that being so concerned about the risk of low battery Mazda then proceeds with wasting precious 12V power on running full multifunctional display and sound warning for 30 seconds just to announce their concerns. It is blatantly obvious that using electrical power in the vehicle without engine running will eventually deplete 12V battery. Mazda simply could’ve put a sticker on the dash stating the obvious.

This 30-minute time limitation, arbitrarily selected by Mazda, is ridiculously short for the daily family car usage. I have owned the car since 23 July 2021 and, so far, only managed 3 days without being tormented by this idiotic warning. My daily car usage routine involves opening/closing the liftgate once and several opening/closing of doors without the engine running, which appears to be enough to trigger the alarm. I don’t think this routine is unreasonable for a family car usage, in particular, if you have kids and need to swap child seats between vehicles. I also take all possible precautions to reduce these warnings by keeping door interlock switch OFF, the keys in RFID blocking pouches away from the car, the car unlocked whenever possible to avoid unnecessary locking/unlocking, having “leaving home lights” disabled and I still can’t avoid triggering this warning daily. So far, I needed to clean the interior 5 times and each of these generated the warning as well. During first few weeks of ownership I did numerous tests and experiments and always had this warning triggered when the actual battery state of charge (SOC) was 95% or above and the state of health (SOH) 98% or above. Bizarrely, this warning is generated even when the car is connected to a trickle charger and the battery is indicating 100% state of charge and 100% state of health. Under certain circumstances I can trigger this warning by simply opening and closing previously unlocked doors 6 times. It is impossible to stop or disable this warning without starting the engine. I followed Mazda’s advice and ran the engine on idle for 7 minutes (added 2 min “just in case”). This resulted in my battery SOC being 1% lower after the engine run than it was when the warning was triggered. This is the ”masterpiece” of Mazda engineering for you.

There is no point of going to the dealer, at least in the UK, as they are hostages of the situation in the same way as the rest of us. Unfortunately, this warning can’t be disabled neither by users not by dealers until Mazda releases a software update. It is also impossible to disable the audio part of this warning or reduce duration of chimes from 30 seconds to something less annoying. I asked my dealer to put some pressure on Mazda to expedite the solution, but they understandably refused. I can’t blame them. Who dares to bite the hand that feeds you?
My ownership experience was totally ruined and I became sick and tired of daily ding-donging. Therefore, I launched an official complaint to Mazda UK about this terrible “improvement” of an otherwise excellent vehicle. In their response Mazda recognised that their solution for the problem was not ideal and said that they were considering increasing the timer from 30 minutes to something more realistic and more practical. However, it seems that they don’t see any urgency in doing so, as they have no date for the proposed software update release and even suggested next year as a remote possibility. It seems ridiculous that a simple task of increasing the timer parameter in the software (more than likely to be a simple variable) requires more than a year to implement. They either have incompetent software engineers or simply don’t care.

From my subsequent correspondence and phone conversations with Mazda UK I learnt that there were hardly any complaints about the low battery risk warnings and that, from their point of view, it is just a minor inconvenience for a few “miserable sods” like me who whinge about it. Apparently, the rest of the owners are “as happy as Larry” with this warning.

If we are serious about the low battery risk problems and want to force Mazda to do anything about it as soon as possible, then we need to start making official complaints to corporate regional offices rather than dealerships. As I mentioned before, dealers are reluctant to pass it to corporate, so direct approach is the only way to register the complaint for which Mazda then needs to respond and take action. I guess someone at Mazda reads occasionally comments on forums like this, but for them this is just a “bedtime reading”, as they have not obligations to consider or respond to our comments. For UK owners, if you want to make a complaint, just send it by email to mmukassistance@mazdaeur.com.

Mazda also conveniently hides their “innovation” from potential customers, as it is still not mentioned in their Owner’s Manual or any other documentation and dealers hide it in their showrooms by following SA-005/21 instructions from Mazda. I read a lot of professional and owner’s reviews of CX-30 online. They are all glorious and none mentions low battery risk warning. Mazda, as any other corporation, understands only one language and it is the language of money. They only will start seriously considering problems if they cause them loss of potential sales through bad reviews.

At last some one who understands my problem I have only had this just over a week my wife really wanted it and yes it’s a lovely looking comfortable car but now she refuses to drive it the first issue was only two days after I brought the car home from the dealership in Swansea south wales a distance of around 150 miles for me I was sat in the car reading the manual with the radio on but after around 20 minutes I got this load donging and the warning like you say happens, the day after I drove up to Holyhead a distance of around 16 miles I left the door open as it was hot the flashing security symbol going off all the time until you start the engine when I got home I parked the car up didn’t lock it and could see the security light flashing I thought no I need to clean the car I’ll leave it unlocked of course I got the annoying dongles going off and the warning which I ignored and guess what my battery was almost flat I contacted the dealer in swansea who said if you want to listen to the radio turn on the engine and he’s said other things like if your going to clean the car inside take it for a run first to charge the battery! I have never heard anything so crazy I have sent Mazda uk three messages complaining about this but no reply this morning I spoke to the south Wales dealer who I bought the car from all he could say was take it to your local dealer who will investigate I doubt if anything will get done but it looks like that’s my next option

Email Mazda customer care, but additionally send a pm on their Facebook page advising emails have been sent, they will respond. They listen are sympathetic etc and will refer you do a dealership. Hopefully not like my local one where there was a firewall of their charges (despite referral by Mazda and the fact is under warranty). The more attention drawn to this the better the impact.

Best advice I can give is when you want to clean your car, put the fob in a faraday pouch away from the car after its unlocked. If you leave the fob in the car (even with everything off) the fob will constantly talk to the car and put a draw on the battery. My misses has lost confidence in the car after the battery failed! It is a nice car though.
