Even the 2023s have the same cheap batteries............

 

Maybe it's time to invest in getting a " good quality battery". Also look into getting a battery jumper you may ever need it but it is good to have.

 

Dealer told me the same. I told him I was getting rid of the Mazda (and I am). Most unreliable car I have ever owned.

 

I regularly leave my car unsued from noon on a Friday until Monday morning. Never had an issue. I do, however, always lock my car and keep my key in a Faraday pouch to stop "waking" the vehicle systems

 

It's definitely short-sighted on the part of automakers to skimp on the factory/stock OEM battery when designing/building tech-heavy vehicles that are more active/power-hungry than ever while sitting idle. 🤔 Seems like a great recipe for creating unnecessary problems, & it also seems like an industry-wide problem of cost-cutting in ill-conceived ways (& tarnish the brand unnecessarily in the process). All the battery/electrical problems I had with my 2020 Toyota over those 2 years that I kept has made me wary of ever purchasing another Toyota, & I consider that a reasonable response from consumers who buy products/brands that give them problems (especially ridiculous problems for the sake of cutting costs).

 

No issues with my battery either. I drive about 8 or 9 miles per week and leave my car un-driven two days per week. but, I will be replacing the OEM battery with a more robust battery another 18 months.

 

UPDATED
Well the dealer gave me a New Battery a few weeks ago.
Have Not driven my car in 4 or 5 days.
Got into the 2023 Cx-30 and on the screen it says battery is low and drive the car to charge up the battery.
Anyways what happen if I left my car at the airport for a week?Do I need a long extension cord?
Makes NO sense at all............Jt

 

Agree. That would be extremely frustrating. Hope you get it sorted out soon.

 

How about the Dealer Put in a Battery that works?
Makes NO Sense for me to run out and buy a battery after 5 months and 1200 miles of ownership.

 

Mazda USA sent me a Email saying hope that all is well and hoping that the Cx-30 is doing fine and they knew that the battery was replaced and I have a Case#. just in case if I still have problems.
They said that the battery could drain down by using the Lighter and USB Ports in the glove box if left on when not using the car.
And they also said that a Battery Maintainer should be used as the dealer said.

Well I wrote back and told them that I don't use the lighter and USB ports, and why should I have to use a battery maintainer after 3 days of no use.
And maybe If I go to the airport on vacation for a week that maybe I should take a 2 mile long extension cord to charge the battery if I need to.
These Emails makes NO Sense butttt I am keeping records on everything..............

 

Get a 680 CCA AGM Battery to replace the old-school 520 CCA flooded-cell stock battery that Mazda still uses on the CX-30. It is designed for higher-tech/newer vehicles with more electrical demands & charges 5x faster than an older-school conventional flooded-cell battery does. Sadly, automakers still tend to use bare minimum batteries to save costs, even though skimping on something like that on a tech-heavy, newer vehicle is a great way to tarnish the brand with customers. My 2020 Toyota was the same way & their OEM stock batteries (they replaced it with a new one multiple times) gave me ongoing battery failure/depletion nightmares for 2 years (among other problems) before finally I ditched it for my 2022 CX-30.

I never had any battery failure/depletion or warning message issues myself with the stock battery on my CX-30 while I still had it installed, but no telling why some CX-30 owners have chronic issues while others don't (system software version issues, regional/country software differences, defective OEM battery batches, ???). Still, my stock battery was more slow/sluggish to start my 2022 CX-30 than the new AGM battery that I finally proactively replaced it with a month or so ago, a few months short of my 2 year ownership mark.

I linked the battery that I purchased below for reference. Despite the poorly-updated fitting tool feedback on the Autozone website (& most other websites with regards to the CX-30), this battery is also an exact drop-in fit compatible with the 2022+ CX-30, just like it is with the 2021 CX-30. Rule of thumb on websites - if it says it fits a 2021 CX-30 then assume it also fits the 2022-2024.

geezzz I took my 2023 Cx-30 Select 5 months and 1200 miles out for a 30 min drive on Tuesday (10 miles}and 4 days later
I go into my car looking for my insurance card and I see a screen on my Dashboard saying Battery is Low and I should drive the car to charge it.
4 days not running the car?
Mazda recommends to use a Battery Maintainer.
Gee if I lived on a busy street (No Garage}and having to hook up a Battery maintainer all day long across the sidewalk where people walk all day long,,,,it makes NO SENSE.
To me its only time when the battery will die again..............

 

geezzz I took my 2023 Cx-30 Select 5 months and 1200 miles out for a 30 min drive on Tuesday (10 miles}

I believe the 30 minutes would need to be at highway speed to fully charge an average battery. I doubt that your averaging 20mph would fully charge your battery in that amount of time.

 

Ohhh I have NO Idea if I should drive the car on the highway to fully charge a battery?(maybe they should let the person know when buying the car?}
I think all Mazda salespeople before selling a Cx-30 should let the person buying the car
that only does local driving once or twice a week that everyone should buy a battery maintainer?
My brother has the same car that he bought at the same dealer and salesperson 5 days before I bought my Cx-30 has not had a problem with his battery and he has the same 1200 miles on his car.
Guess maybe because he has noooo problem and I do, its my fault?

 

One month and 200 miles later, the battery died for the 3rd time.Car is 6 months old and has less then 1500 miles on it..
Mazda dealer tells me that I should be driving the car longer to charge the battery and I should not be going slow to charge the battery.
Well I live in Manhattan NYC,,,,so I guess it means that I should Drive from Downtown up to Harlem and head east to the FDR Drive back to downtown that will take me 1 hour with about 20 miles and with traffic all the time will be only to do between 15-25 MPH stop and go with traffic to charge the battery?And have to do it a few times a week?In NYC you only have to drive 1-2 miles to the Supermarkets or anything else,Nobody drives over 5 - 10 miles each week unless you wanna go to New Jersey lol............Hope they correct the Battery Drain..........

 

Bite the bullet & get an AGM battery. All newer vehicles should come with them standard IMO, but automakers are either clueless or cheap (ridiculously cost-cutting where they think they can get away with it for added profit). My 2020 Toyota had the same repeated battery failure issues, with its cheap, old-school flooded-cell battery. I finally proactively replaced my CX-30 520CCA flooded-cell battery with an 680CCA AGM a few months back at about the 20 month ownership mark to finally save myself the worry of coming out to a dead battery one morning, since I only go out driving twice per week & about 3500 miles per year. I luckily didn't have any issues prior to my AGM battery replacement, but constantly worried about it given the experiences of other CX-30 owners & my 2020 Toyota chronic dead-battery problems. Newer, tech-heavy vehicles just have more passive power-draw demands.

Also, watch this video about alternators & vehicles battery interactions & common misconceptions regarding "charging batteries" via driving/running vehicle. If you battery has been depleted one or more times, the damage is already done.

 

Well this topic is getting a lot of responses, to which I have been following out of curiosity.
Is it the battery?
The vehicle?
The lack of use to fully charge?

Knock on wood I have never had a battery go dead in under 5 years from new.
So is it the quality, or the tech bloat and under strength battery, or the lack of use, or a parasitic draw?

Cheap batteries may be the culprit with a hit or miss failure rate higher than name brands.
In my humble (lol) opinion, any new owner 2 years or less, should have the problem battery replaced under warranty.

Step up Mazda, make it right and build disciples from your customers.
Word of mouth goes a long way.

There is a saying in business, for every satisfied customer, they will praise the product to 3 or 4 potential purchasers.
For every disgruntled customer, they will pass along their feelings to 10 or more.

Do the math Mazda, in the long run you win with exceptional customer service.

 

Mazda says that driving the Cx-30 once or twice a week is not good enough,I will have to drive it for Longer periods and higher speeds.
Well that does NOT make any sense since I bought the car to use it local and not put 200 miles plus a week on the car., local means to me and many others I am sure maybe go buy a pizza,supermarket and Sunday church, maybe 25 miles a week.And its nuts thinking that Mazda tells me a few times to buy a battery maintainer.I can see myself parked in New York City on 14 street and having to have a 1000 foot extension cord while thousands of people will walk over the cord lol...............Makes No Sense at all

 

Today on New Year’s Eve 2024 my 2022 CX 30 battery was completely dead earlier today. I’ve never had any issues with the car since I got it new in May 2022. I had a jumper delivered and it was able to start the car. I let it idle for about 15 minutes and then drove for 15 minutes to run an errand. When I got back in the car, I noticed it wasn’t a normal sounding start like it had a moment of hesitation. But that it restarted made me feel like maybe it was OK. I went on a second errand a few minutes away where I was in the store for 20 minutes and when I got back to the car, the battery was completely dead again. Luckily the guy parked opposite me was able to give me a jump and I had bought jumper cables on that second errand just in case. I also bought a charger and I’m letting it sit on there all night to see what happens tomorrow. Has anyone had the security light on the dash constantly blinking even though the car is completely shut off and locked? That is something I haven’t seen before. I had the car serviced last week and everything was just fine. It seems like strange timing that they did an oil change and tire rotation and then a few days later, these problems are happening Is it just a junkie stock battery and that’s the problem?

 

As far as the security light blinking yes, it does on mine as well.

 

Do yourself a favor. Now that the battery has been dead a couple of times, it days are numbered. Buy a new quality AGM battery with better reserve and CCA.
Mazda did not do itself or its owners any favors with the battery from the factory. There has been numerous owner’s experiences concerning this. Though many have not, it is very random suggesting poor reliability from the OEM battery.
Many threads here on the forum about this.
Just scroll down below the last post and see “Related threads”.
Best of luck.

 

Got my CX-30 back a few days ago.
They said they could not find anything wrong with the battery, think they just recharged it.
But they insist that I use a Battery maintainer.
My bother has the same car and same miles on it(1500}and 6 months old and he has not had the problem.
I wonder do they have a Tech go outside each night to make each Mazda fully charged with a battery maintainer lol?Since all the cars can sit on the lot for weeks and months not running?

 

It's best to invest in to a good after market battery and avoid the hassle

 

I agree its a hassle,,,but Mazda should take care of the problem and not me...............

 

True it is a hassle but after the warranty is up they won't do anything.

 

I now have my 2023 Mazda 3 Skyactive X absolutely dead on my driveway for the third time - not even enough juice to operate the door locks and its only been sat there since yesterday morning. Ongoing negotiations with the dealer and I'm waiting for them to call me back before I jump start it again! I look forward to hearing any solutions.

 

The one "universal" solution is to go buy a higher CCA AGM battery. Remember your time and aggravation trying to get Mazda to do something worthwhile is worth something. Mazda is not going to help you unless there is a service bulletin to update the software to "maybe" correct the draw. But if your VIN does to show the bulletin they won't do that. Therefore they will charge the battery and send you on your way (only to have the same issue within days) or put a new battery in it, which will likely have the same issues sooner or later.

In summary. Solutions or stop gaps are
1. Buy yourself a better battery (AGM with higher CCA)
2. Battery maintainer (only works if your car is not parked outside)
3. Faraday bag for your remote and delete the MyMazda app (no proof the bag or deleting the app solves the issue).
4. Keep a battery jumper pack (like a NoCo) in your car and know how to use it)
5. Keep going back and forth with your dealer, knowing they will a. Charge your battery and call it fixed, b. Install a new battery (you will eventually have the same issues c. Re-flash your software if there is a service bulletin related to the software causing drain.

I am using solutions 2 and 4 above for now since I park in my garage. But as soon as my battery is 2 years old I will definitely invoke solution number 1 and continue solutions 2 and 4

 

I’m going with options 1, 2 and 3. I do, however have my parked outside my apartment complex but I do have a power cord and it fits into a socket 8 feet away with my battery maintainer, so I’m good. I will wait for the two year period. If not sooner and purchase an AGM battery.

 

Hi I was wondering what battery did you replace it with . Cheers.

 

Fourth time I had the Mazda Cx-30 at the dealer.
1st time they said that the Battery was DEAD and Mazda towing jump started it and Mazda they Charged it to Mazda Specs and was told to get a battery maintainer.
2nd time the battery died and I had it jumped and Mazda Replaced the battery.
3rd time battery died and had Mazda take care of it, they said nothing was wrong and just charged it.
4th time(last week}Battery Died and Mazda Towing said that the battery was DEAD and had it towed to Mazda.After a few days Mazda says nothing was wrong with the Battery and they just Charged it and told me to get a Battery maintainer.Dealer told me to take the car on long trips and if the car is Not used for a few days that I should have a battery maintainer.
I think after the 3rd time Mazda just wants to get rid of me and not looking to see where the Battery drain is,I feel Mazda knows about these problems and are not interested having Mazda Techs to find the problem(Would take too long to find and cost too much in tech labor}.

 

You would think that the dealer would just give a new battery they can write it off as a warranty cost. Some dealers are just that cheap so sad. Maybe you should send a letter to Mazda explaining the situation and you are not happy the dealer. The only thing you can do now is get your own battery at least you can get a warranty for battery. Just a thought.

 

From what I have read, people who have had persistent battery issues with the 520CCA flooded-cell stock OEM batteries seem to have them go away when they shell out the ~$250 bucks or so for a good AGM battery to replace it.

Since late 2019, my normal driving behavior has consisted of driving my vehicle 2 (or sometimes 3) outings per week & approx. 3300 miles total per year. No highway miles, just all around-town suburbia running around basically. About 30-35 miles per outing, more or less. My 2022 CX-30 CE gave me no problems for the 21-22 months that I had stock battery with that routine, but I still proactively replaced it with an 680CCA AGM battery just to get rid of that persistent "Russian Roulette" stock battery worry. That same routine with my 2020 TNGA Toyota Corolla SE sedan resulted in multiple dead battery occasions & several battery replacements during the 2 years that I had that vehicle. So, go figure why two passive tech-heavy vehicles reacted so differently to the same driving routines over the 2 years spans, each with their stock batteries (& multiple replacements in the case of the Toyota). 🤔

For the 38 driving years prior to my 2020 vehicle (my first passive "tech bloated" vehicle purchase), battery problems, issues and/or lifespan were never even on my radar. Nor was even the thought of using a battery maintainer (which would be a big hassle). They would always last at least 4 years with the original factory battery & I would proactively change them out at the 4 year mark. Never an issue, or anything to think or worry about.

 

@SDH Do you have a voltmeter? One of the things we can do to judge how well your battery is holding up is to measure the open circuit voltage after the vehicle has been sitting at least four hours to dissipate the surface charge. 12.65v is a fully charged battery. 12.1v is les than a 20% state of charge. The engine will usually still start at 11.8v but that is a completely discharged battery that the average owner might not realize is a problem.

 

No, I don't have one. I probably should get one though.

 

Well the way I look at it, my Brother bought his 2023 Cx30 from the same dealer as I did just 5 days before I bought mine.
We both have 1500 mile on them and he has NO problem with his.
As I said I bought my car in June and Sept I had problems(3 months}
If I lived in the City and park on the street like 50% of the people a battery maintainer would make NO sense since there is no place to plug it in..I go out twice a week and try to put little miles on the car(10 - 15 miles}, since I bought the car for local driving and not for long trips.and maybe 3 - 5 Days Not using the car and maybe drive 10 miles here and there and it makes No sense that a battery would die?
You would think that Mazda on their lots have at least 100 CX30,Cx5 and Cx50s that are sitting there for weeks would all have a Dead Battery???

 

We both have 1500 mile on them and he has NO problem with his. SNIP___

As I saidI go out twice a week and try to put little miles on the car(10 - 15 miles}, since I bought the car for local driving

This is a basic electrical math problem. The cars on the dealers lot are sitting undisturbed for the most part. The battery can last three to four months and still have enough energy to start the car, although a good charging would be advisable. Going out and running the car for ten to fifteen miles twice a week depending on variables such as how many accessories are on and how much stop and go traffic is encountered could actually be depleting the battery instead of helping.

To most vehicle owners the battery problem appears to happen overnight, as in the car worked fine yesterday but had a problem today. In reality there is measurable evidence that the problem occurs over time. In some cases faster than others. While your brother hasn't appeared to have any problems a check of the battery's state of charge and health could confirm that he is or actually isn't having a problem that just hasn't revealed itself yet.
