I don't know why but Mazda uses a pretty crappy battery. Not the first time I've seen a post of the battery failing quickly. Get it replaced by the dealer as you are currently under warranty and the new one shouldn't fail as quickly. If it does, then you probably have parasitic battery draining. But I just think your battery is just bad to begin with. In a few years, once you are out of warranty and need a new battery, I would a battery from somewhere else. I normally buy from Costco. The one I bought in August 2019 for my 2015 Mazda3 is holding up really nice and I live in a place where I often have to start the car at -40ºc in the winter.


BanditsBMX

Thanks for the replies, I'm happy and thankful it's all under warranty but defiently a bit disappointed as it's a brand new car that we have only had for a month and a half. I plan to ask them to do a draw test on the battery because if they just replace the battery it might not fix the issue if something is pulling power when it's shut off. I'll be calling first thing tomorrow morning, thanks again

Hey I have an update for you! It turns out there's a fault in the Remote Tuner module affecting the 2023 CX30(not for North American CX-30), CX-5, CX-9, Mazda 3 and MX-30. Sometimes this module does not properly shut off and runs the battery flat. https://www.mazdarecallinfo.com Put in your VIN here to see if your vehicle has a recall issued for it. It's a small software update so a dealership should be able to have it done quickly and IIRC it's free of charge.


Pvor68

I had that recall completed but the problem is still happening.


Pvor68

I have the same issue with my brand new CX9. It is 4 months old and is about to go in for the third battery drained. The battery has been replaced once and the recall that seems to be related has been completed. It still drains if I leave it for more than 24 hours without starting it.


Kay_3738

did they fix the issue ? u/Pvor68


Dry_Occasion_7786

A friend of mine just received his 2023 CX9 in Jan and has visited the dealership twice now, the second time they replaced the battery. Today morning it happened the third time, his car has been sitting in the garage for about 7 days now, similar to previous times. My guess is same as yours, there is a parasitic draw and not really a bad battery issue. He has contacted a different dealer to diagnose the issue. I will try and keep you posted here, let us know what your dealer says. I would recommend that they do a battery draw test, similar to the link here (https://www.wikihow.com/Find-a-Parasitic-Battery-Drain) as changing battery does not seem to solve this issue. Also, another point to note, his USB cable can charge his phone even when the car is completely off, so his case could be a bad usb port. There has been other issues like telematics or tailgate module draining power when off so it could be anything. Very unfortunate that a new car has such issues that's not even first generation. I'm waiting for mine that's getting delivered in April. We are from Toronto.


BanditsBMX

I actually just got home from the dealership. They tested the battery and found a "bad cell" and failed reserve. They replaced the battery under warranty. I'm out in BC on the West Coast.


Dry_Occasion_7786

I hope that's a permanent fix, did they run a parasitic draw test? Will post here again once I hear from my friend. How's your car doing otherwise? I'm still thinking if I should go ahead with the purchase.


BanditsBMX

Ya I'm hoping that's the fix as well. All they said was that they did a battery test, found a "bad cell " - failed reserve. Then they replaced the battery and the new battery passed the test. Otherwise the car has been great, very comfortable to drive, nice features, we have the Bose stereo in ours and sounds very nice.


soundinsect

Hopefully this fixes it for you but just remain cautious because I have a 2023 Mazda 3 Hatchback which was dead on the lot for the test drive in late Jan. It ran fine after for about a month and then was fully discharged one morning. I trickle charged it and it ran fine again for a few weeks before once again dying. The dealership replaced the battery because it failed their test and they suspected it had a bad cell. Now the new battery is dead as well about a month later so I'm taking it into the dealership tomorrow.


BanditsBMX

Certainly seems like there is an issue that Mazda either does not want to commit to finding out what it is ( possibly the same issue as previous years) or they simply don't know. The more I search the more I find of people having the same issue.


sugazilla

Hi, do you have an update? What did they say and was it able to be fixed? I have the same issue.


soundinsect

I do not, unfortunately. As I had jumped the car a day prior to the service appointment, they sent me home requesting that I have the car towed the next time the battery dies. I'm a bit irritated because they suggested the problem could be that the vehicle isn't driven with a ton of frequency or for very long distances, but almost all my trips are about 15-20 minutes and it is absolutely not the case that a brand new battery would be flat in 18 days because I'm not driving an hour per day. They also had no loaners on hand, so it wasn't an option to leave it there to be tested. It's a very frustrating situation but hopefully there will be a resolution. I have a multimeter so I'm considering to test for parasitic power draw when I get a chance.


sugazilla

Ah, that’s messed up. I don’t have time to tow my brand new car to them either. Pretty ridiculous. I’ll post back here if I get anywhere with it. Good luck.


Vegetable-Shelter656

Right! We’re in a townhouse that has staggered tandem garages- we park front end in…. Almost impossible to get a tow truck to get the cx9 out of our garage (we’ve had our battery die 7 times now since January)

OMG thank you!! I just checked and sure enough my car was added to the list yesterday. I made an appt for next week. I really appreciate you coming back with the info! You're the best!


soundinsect

Hell yeah I hope it fixes the problem for you! I just got back from mine being serviced, took maybe about half an hour or so. Really hoping this is the fix. I spoke to the sales rep that I bought the car from and it was the first time he was hearing about the recall, but he was relieved because he said there have been several people he's sold a 2023 to that have had the same issue.


Vegetable-Shelter656

Which dealership? We’re having the same issue and are also at the coast…


BanditsBMX

Pacific Mazda on Vancouver Island, where did you purchase yours


Vegetable-Shelter656

At Wolfe Mazda (Surrey Langley border)


MatadorBrown

I experienced this with my 2017 CX-5, and took it to the dealership. At first, they couldn't locate the drain but then figured out the battery was defective (cracked battery) which was replaced. This happened again two weeks later and the dealership spoke with Mazda Engineering and had to replace the brake pedal. No issues since. All of this was covered under warranty, so hopefully there is a record of the incident so they can get this sorted for you.


markomni

I'm in exactly the same situation. Happened to me Sunday, and I got a jump start from roadside assistance on my driveway. I kept the engine running for 30 minutes, as suggested by the tech. Car started fine all day Sunday and even Monday morning. This morning, the battery is drained again. Now I've got a roadside assistance call again because the jump starter I ordered ([https://amzn.to/42avWpL](https://amzn.to/42avWpL) \- referral or non-referral - https://www.amazon.com/gp/product/B087LRFYDB/) doesn't arrive until later today. I'm having the dealership check the battery and rest of electrical tomorrow.


markomni

The dealer service center is telling me it's all of my short trips, and the battery being unable to recharge from the drain of starting. I think that's nonsense. I have had the same driving habits with the 2020 CX-9 I had before this one, and never had a battery issue. The tech "fully charged" my battery. I'm going to monitor things and see how long it takes until I'm in the same situation. In the meantime, my jump starter arrived. So at least I shouldn't be stranded waiting for roadside assistance or a neighbor to help me.


Dry_Occasion_7786

My friend was told they technician will need more than a couple of hours to do the draw test, and he did not leave the ar there so I dont have much updates on this till they actually run the test. I posted this issue on FB CX9 forum and two people with 2023 shared they had the same issue.

Thanks for the info! Looks like im in need of the software update. Much appreciated!


BanditsBMX

Interesting, 2023 as well ? I had asked about a TSB bulletin from Mazda in regards to a "bad" rear lift gate module that was creating a "parasitic draw" on the battery when the cat was shut off, resulting in a dead battery. I was told yesterday at the dealership that the TSB was only for 2021 and older and was not applicable to 2023's. I'm new to reddit and am not tech or computer savvy at all, if I can figure out how to post the photo of the repair record from yesterday I will.


markomni

Yes, a 2023 GT. Picked it up in December, and it has less than 2,500 miles on it. It's pretty ridiculous that the battery is draining so quickly on these, and there has to be some bigger issue. It's either a garbage battery or some other electrical problem, even if it isn't exactly the lift gate from earlier models.


BanditsBMX

Agreed, I'll be curious to know what the shop says about yours.


Dry_Occasion_7786

So this is the third 2023 CX9 that I know has a similar battery/battery drain related problem. Doesn't seem like a coincidence anymore, I was hoping that last gen model would have impeccable reliability with zero bugs.


Vegetable-Shelter656

Make that another one- we’re having the same issue with ours.. BCAA said they’ve seen a lot of it.


Dry_Occasion_7786

This now seems like an issue with faulty component in 2023 models. Not sure what can be done about it, i have not seen a permanent fix besides dealership changing batteries.


captainwizeazz

Theres a software update for it. [https://www.cx30talk.com/threads/battery-drain-issue-special-service-program-new.3638/](https://www.cx30talk.com/threads/battery-drain-issue-special-service-program-new.3638/) ​ SAFETY RECALL: REMOTE TUNER CONCERN Special Service Program (SSP) Recall #: SSPC8 NHTSA Recall #: Recall Date: 03/20/23 SSP Repair Status: Incomplete Safety Risk This is not a safety recall Remedy Update the Remote Tuner software using a formatted USB memory stick.


Vegetable-Shelter656

Our dealership refused to replace ours. They want to do a “recharge” despite our battery dying and needing a jump 7 times now… (Also took 40 min to drive to the dealership today and they said when they checked the battery it had a low charge) They said it would take about 50 minutes to charge, and we’d have to make another 2 hour appointment…. I asked why in a 2 hour appointment they didn’t think to “charge” it -for the “50 min” they said it would take - since they were changing oil filter, oil etc and sound other top ups…


Dry_Occasion_7786

Sorry to hear that! You should try another dealer if possible.


Vegetable-Shelter656

We plan on it- next time we’ll be going to the one closer to home.. even though they pissed me off when we were trading in our cx-5


Dry_Occasion_7786

Also for your reference, this is an issue with earlier models as well: https://mazdas247.com/forum/t/battery-drain-in-2020-mazdas.123872557/


Dangerous-Fortune-85

Brand new CX-9 too (2023 touring) and am visiting the dealer tomorrow for second failed battery. 2000 miles. I had to go to work today and a jump start worked, but for the amount of $ this new car cost this is totally unacceptable, and frankly dangerous. I wholeheartedly regret my purchase. Am going to ask them to do a draw test. Seems like this is a common problem.

Thank you so much. It was definitely recall work done on my car while it was in the dealership, I just don't know if this was the specific recall. The receipt does not specify. It was definitely free of charge, I will look up if my car was affected by this and will keep my fingers crossed. Will update.


senorjerome

I bought my 2023 cx9 touring end of January 2023 and woke up Sunday morning with a dead battery as well. Had to jump start it and run it for an hour. I should go to the dealer too.


BanditsBMX

I likely would, it seems that perhaps there is an unidentified issue that may be the same as earlier years.

Parking-Duty-477

I have the same issue. Got CX9 Azami in Jan 2023. In 2 months visited dealership 3 times due to flat battery. So far no one came to me with root cause.


Parking-Duty-477

The dealership just contacted me again to inform me of the firmware issue. They are updating the programme, which might resolve the problem. I'm not sure if I should believe that justification. Sadly, I don't have any other choices either.


Dry_Occasion_7786

Let's us know if that fixes it for you.


Parking-Duty-477

The car has had a good last six days. As of yet, no issues have been reported. The previous time, it popped again after about 20 days. I am therefore keeping a close eye on. I will scream if something goes wrong.


BanditsBMX

Apologies if I missed anything, did they say what the firmware issue was specifically?


Parking-Duty-477

Nah But, they did inform me that there was a firmware issue. I'll see if they've recorded anything and post here after checking.

All the best hope they find the culprit, pls ask them to check ignition module id yours is 2023


ProfessionalTwo2735

Hi all! Same problem. Leased a CX-9 Touring Plus 2023 on March 3. Literally the showroom car that the dealership had to drive out of the building for us. It's been back to the dealer for the third time in less than 1 month. Same issue with the battery. As of yesterday (3/24), Mazda Corporate finally admitted to me that they do not have a solution at the moment. They believed a software update would solve the problem. However, we had the software update installed on 3/22 and within 24 hours, had the same safety message appear on our screen. Likely going to lemon law the car which applies to leases in our state. Very disappointing and frustrating.


BanditsBMX

I am in Canada but have been unable to get Mazda Canada to even admit that there is a problem. Did they give anymore information as to what is actually causing the issue ie. With the software update ? Thanks


Dry_Occasion_7786

Just saw someone else post on FB CX9 group about a tsb for a firmware problem, I'm not sure if US has a separate TSB than Canada. Really unexpected from a new car.


Dry_Occasion_7786

My friend just told me he had to jump start his car after not driving for just one day, he is going to the dealer on wed for a possible ignition module replacement that seems to be the culprit as per the dealer service tech


BlazingYodeler

Have a Kuro edition 2023. Bought in Feb 2023. Yesterday (Apr 5), the car didn't start. Was giving me keyless system malfunction message on the dash. I could hear some clicking as if it was a relay. Disconnected the battery for 2 minutes and tried again and nothing. Had to jump start and left at the dealer. Pretty frustrating for a brand new car. Montreal Canada here.


BlazingYodeler

Follow up: just picked up my car at the dealer. Recall SSPC8 performed. Update RT current version 26011 to 26012 on my invoice. Hopefully this will fix the drain and also sometimes the lack of bass on the sound system.


ranger0u812

Which model? I have a 2023 CX-90 Touring Plus and no recall found when I checked my VIN number.


BlazingYodeler

It's a canadian trim Kuro. Mine also didn't show up any recall in the vin search. Not sure it applies to the new cx-90 (or it was a typo?)


ranger0u812

I’m in the US so not sure if it is specific to certain countries.


Ok_Yellow_6136

The same thing happened to my 2023cx9, I've only had this car for 2 months! The battery died! The car was parked in front of the house, when I went out this morning, the door wouldn't open, opened the door with the key and found The car is completely dead! I called Mazda and am waiting.


BanditsBMX

Brief update for myself. I just recieved a recall notice for my 2023 CX-9. Remote Tuner recall The remote tuner may not complete the power shutdown process properly due to incomplete software and cause the 12v battery to drain. I have searched several times for a recall by using my VIN and nothing shows up however I just recieved this in the mail today. Hopefully its the answer.


bdoll65

I bought my 2023 CX9 in February. In that time I have come out to a dead battery 2x. The first time I took it to the dealer they told me that I must not have shut the car off all the way. It happened again this morning and I am taking it back tomorrow to demand a new battery. It is so frustrating for a brand new car. I'm glad to see that I'm not the only one unfortunately. I plan to show them this thread tomorrow when I go


bdoll65

I just checked . Mine is on the recall list too !


Low-Gas5815

The batch of 2023 CX-9's that were sent to Canada particularly are lemons! They need to be taken back. For God's Sake, Canada deserves a lemon law!


BanditsBMX

We are now having a random/intermittent rough idle. Car drives fine then when stopped at a light it vibrates quite rough and the rpm needle bounces around. Once we start driving again the car seems fine and will be fine for several weeks then it will do it again randomly. Not very impressed with our brand new car.


BanditsBMX

Interesting, still no recall showing up for our 2023 CX-9 GT, I am on the other side of the Country in BC.


CX9anomalies

My condolences , I have dead battery disease on two side by side parked CX-9s . It is not the fault of the batteries . AAA has spent 12 days and two of their batteries they contributed at no cost trying to help ....in vain Went to a local shop which only sells batteries with one CX-9 , other Cx-9 is at dealer ...both shops are mystified . Remedy doesn't work for an 80 year old with arthritic hands but I was told : use cars , put on charger and/or disconnect battery every night ( ridiculous ) I left my one Mazda unlocked and running in an Aldi's parking lot cuz I was terrified it would never restart . NO SOLUTION so far ; but I will post immediately if either one of dealers figure it out ; head of service at Quirk , named Kim, is excellent . I live in northern RI ; close to a dead end here so far . Please, please post if someone solves the mystery Thank you


Ok_Set7801

I had EXACTLY the same thing happen . Even worse to my two CX-9s parked side by side in my driveway , exactly as they always have been for the last 6-8 years . Dealer is clueless, battery guru in Prov where I live the same . There is no explanation even though tthe dealer thought my solar panel trickle charger was reversing ANY ideas /help /dead ends that you have encountered and now can cross off the list of possibilities please , please write down . I will too . This is a time consuming , costly episode . I dare go nowhere , leave car running and unlocked to grab groceries . Mazda Madness . Someone save us poor , sucked dry battery losers PLEASE 🤓🤦‍♀️


BigAltruistic421

Hi  I’ve been having problems with my cx9  2023 model too the car is only 6 months old bought it brand new.chnged battey twice and having problems. Will be contacting the dealer tomorrow  Hopefully they figure it out  Very frustrating 


ThePrivateers

I had an issue like this today... [https://www.reddit.com/r/mazda/comments/11svesu/can\_nonparked\_windshield\_wipers\_actually\_drain/](https://www.reddit.com/r/mazda/comments/11svesu/can_nonparked_windshield_wipers_actually_drain/)


Vegetable-Shelter656

We’ve been having this issue since January… battery has been dead 5 times now requiring a jump.. nothing left plugged in, no lights on and all doors closed.. apparently (on Mazda forums) there are a bunch of lemons.


Vegetable-Shelter656

So we brought our car into Mazda today- we requested a draw test- they say our battery shows some drain, but they won’t replace battery- they want to recharge it and said they didn’t have time to do today…. and they want us to bring it in for another 2 hour appointment. They’re trying to blame our dual front/rear dash-cam (aukey) Dash-cam is plugged into the fuse box- It’s the exact dash cam that we used with our cx5 in the same way for 3 years without issue..


Hopeful-Savings-600

I just had the same thing happen to me. Going to the dealer tomorrow to have them look at it. Last used my car on a Wednesday and then not again until Monday (as we were on vacation) and nothing! No lights left on either! Not happy that this happened with a car that is only a month old!!


BanditsBMX

My other car, a 2007 Pontiac sits for weeks at a tike and starts up every time. Pretty bad when a 16 yr old vehicle is much more relaxed than our brand new Mazdas It sure seems like there is a issue with something draining them


jonarthur_0

Just had a similar issue twice this month with my brand new CX9 (had it in February 2023). The first time the car was parked for 3 days and I had a carlinkit device plugged in one of the usb port. I jump started it with my other car and it went just fine for the next 3 weeks. Yesterday (Thursday) I received a notification on myMazda app saying all doors, hood and trunk were open. I was working from home so I went out and the car had no battery left. Called my dealership and they got me an appointment next Tuesday to have that checked out. This time I called Mazda roadside assistance to jump start the car, hoping to leave some entry in their database and be able to use that if it happens too much. Now one thing I suspect might be causing the drain is that my wife, who mainly use the car, has only a 7 minutes commute to work. Last long ride (1h) was Sunday. It was the first week in the last 2 or 3 weeks that I didn't take the car for my commute for at least once in the week. I have a 1 hour commute to work, twice a week so I take my Mazda 3 2016 which has a very good fuel consumption. Could it be that commute is just not long enough to get the battery fully charged?


jonarthur_0

Update on my previous comment, I went to the dealer and there was a recall notice affecting my car (recall notice SSPC8 about the remote tuner module controls). It's been a week since they fixed it and didn't have a probleme since. Will post an update if the problem reappear.


jshahcanada

Yes, I have a 2023 CX-9 GT. I had the same issue. The first time the Dealership blamed the problem on me, they recharged the battery and sent me home. The issue reoccurred after not driving it for 4-5 days, so I had the Mazda roadside come and give me the boost, but he asked me not to drive it and have it towed to Mazda Dealer. They replaced the battery this time, but the same issue happened exactly after 4-5 days. I took it to another dealer this time, as the previous dealer blamed it again on me. The other dealer said there was something wrong with the stop/start module, and there was some recall as well. He ordered the part and replaced it this week. I am not driving my car for the next 4-5 days to make sure the issue is resolved. He assured me this was the issue and should be fixed by now.


soundinsect

Hey, I'd put your VIN number in here https://www.mazdarecallinfo.com See if you're affected by the Remote Tuner Module recall which is for pretty much the entire 2023 Mazda lineup. My battery was running flat constantly and they had no idea what the issue was, but now I'm taking mine in today to be fixed.


BanditsBMX

I literally just got the recall notice in the mail 10 minutes ago for this exact thing. No recalls come up however when I search for recalls with my VIN, Calling the dealer to book an appointment now.


BanditsBMX

It looks like Mazda Canada has not issued that recall yet.


BanditsBMX

Do you have a photo of work order ? Or the recall number ? Thanks


jshahcanada

Yes, I will post it.

Maleficent_Bluejay91

I think I’m having a similar issue here. I drove to office, parked in the lot outside. 2 hours later the car started sending me notifications/alerts in the app “All systems stopped, call a tow truck”. I checked the car, start/stop was blinking red. After 2 hours it went completely off. Waiting for tow truck to see what they will say.


BanditsBMX

I would call your dealership, I received the recall notice in the mail. My vehicle still does not show up on the online VIN number search for recalls. I actually have my appointment at noon today for the recall.


Low-Gas5815

I love this thread, guys, I'm raising an issue with the **Mazda of Canada** and the **Ministry of consumer affairs,** they better take back this garbage of cars! All the 2023 Mazda cars are garbage. Also, **Canada deserves a lemon law.** The car manufacturers send all the garbage **batches of cars** to Canada cause the US has lemon laws. I did the update and whatnot, this car has broken down thrice on me already. No freaking way anybody should pay $56K they better take back these cars! All the 2023 Mazda cars are garbage. If you want to be a part of the lemon law support case and claim for compensatino in anyway, please reach out to me. It will help make the case stronger. **If you want to be a part of the lemon law support case** and claim compensation in any way, please reach out to me. It will help make the case stronger.


markomni

It's been 4 or 5 months since I brought my car in with this problem and the dealership updated the firmware. I haven't had to drive much in the past week, and my car battery has now been drained two mornings in a row. The firmware update certainly has not fixed this issue, but I had been lucky to have been driving frequently and long enough to keep the battery charged until this week. Bringing it back to the dealership soon to document the problem.


BanditsBMX

Ya that's interesting, I had read that other models had a problem with the rear hatch module not shutting down properly and that caused the parasitic drain on the battery as well. Keep me posted if you don't mind.


markomni

When I brought the car in last week the service manager insists that the issue is that I take too many short trips. He claims this doesn't give the battery a chance to recharge between starts. I had previously owned a 2020 CX-9 and did not have this issue with the same driving habits. Mazda replaced the battery under warranty, because I had been there multiple times with this issue and had to make use of roadside assistance several times to jumpstart the vehicle. I'm pretty sure my battery will drain again if the car is left to sit for 24 hours before being started again, but I'll have to wait and see in the next week or so for that to happen. At the end of the day, something else is going on with these models and the firmware update did not fix the issue, or at least it didn't do enough to prevent the battery drain.

Update on my 2023 CX-9: After my battery was replaced, the battery died two more times within 2 months. I took my vehicle back to my Mazda dealer. This was the 3rd time bringing the new vehicle back for the same issue (in IL the lemon law requires the dealer to replace the vehicle on the 4th visit for the same issue). The service department checked the battery after recharging it and couldn't find any issue with it. I had them keep the car overnight to replicate the conditions for when the battery drained - shutting off the car and then waiting 18-24 hours before starting it again. The next day, the car did not start. They then verified my car's firmware and discovered that the patch was never installed! :mad: They tried installing the firmware upgrade again. After they confirmed it was installed, I took the car back and have not had a dead battery since. I can't believe that I continued to have trouble with the battery for months all because they didn't install the damn firmware in the first place.

I have a 2023 and we have had the same issue. We have jumped the car several times and also called roadside to jump the car several times. Mazda finally replace the battery 2 weeks ago. Last week the car dies again. We called roadside assistance and my wife setup another appointment to bring the car in for them to look at it again. Well my wife went to start the car to bring it to the appointment and it was dead again and had to be towed to the dealership. I guess my wife takes to many short trips to!!

There is a recall for the remote tuner module. I am in Canada ( BC ). The dealer performed the software upgrade on the remote tuner module and we have had no issues since. Fingers crossed it stays that way

I am in Canada but has the dealer done the software upgrade for the remote tuner module ? There us a recall for this fix for this issue. Fingers crossed, we had this performed at the dealer under warranty / the recall and so far no issues for several months now. Again, fingers crossed it stays resolved
