Some may see that normal charging stops or is finished, but the battery is not fully charged.

The cause of this is because of certain brands of AC Adapters that are used where charge completion is improperly detected by cars PCM.
Appears Zaptec and GARO brand AC Adapters can at times give this issue.

The fix is to recalibrate the PCMs software and this can be performed by your Mazda Dealer with MDARS.
As an owner you MUST complain of this Charging issue for the Dealer to perform update as it is not always automatic during servicing unfortunately.
If your MX-30 was made after April 2022 then this update does not apply and you should not have this charge issue.

This is not a recall.

This might be, but sudden stopping to charge surely does not just has to be an issue with firmware of the car or an adapter problem.

My car has been charging on a 'Mennekes type2' granny-charger, and it did this flawlessly for about 3 months. It draws 13A though. I don't know how installations in homes are made in other countries, but in the Netherlands its done with 'central boxes' in the ceilings, mostly precast concrete. From there plastics tubes branch out for wall sockets and switches. Problem is : in every socket there are connections with clamps. Older systems had screw-on metal springs. But at a persistent high current you can get surface corrosion, contact corrosion. This builds up resistance and results in a voltage drop.


I'm not an electrical engineer. I moved the same car/charge another socket, and it works flawlessly.
This after 7 interrupted charging attempts on the previous socket.

Above the old, more secure but more time consuming method. Now abandoned for home installations.

Below the newer system used. Instead of large contact surfaces, there is now a 'ring' where the wire could make contact.
More likely only top/bottom sections. And the top edge of the tip. I guess this is fine for a 100 watts lightbulb, but I have my
doubts for the safety at 13A for ten or more hours continuously !

So now I will switch to a direct insulated cable from the switch-box to the face of the house where I charge.
Also I will use another charger, that I use for my Range Rover PHEV. This is also 'type 2' , but gives max 10 A.

Thank you so much for this information!

I have the this problem with my MX-30 and I have a Garo AC 3-phase charger at home and car car says that the charging is finished all the time.

I have used this charger for two years now and charged Teslas, Kia and Hyundai without a problem.

I went to Mazda here in Sweden to a shop and they didnt really believe me and blamed the charger and wanted to quote me 900:- SEK for troubleshooting.

Now I have the answer thanks to you!
I just created this account here to thank you.

Regards,

Adnan from Sweden

No probs, your Mazda Dealer must software update ECU with MDARS.
Seeing you are a veteran with plugins, how do you like your MX-30 compared to the others you have owned.
Does the small battery range really bother you, I believe people do not understand Mazdas philosophy with their first electric car, a bigger battery adds weight which will compromise handling. MX-30 was and is only supposed to be a city car not a Grand Tourer.

 

[AdnanSWE]

I sold my Tesla Model Y because the comfort was rubbish. After a long trip to Italy on vacation with the car i could not stand it anymore. I sold it with a profit so win for me.
I have owned several BEV and the batterysize is not the most important. It is the interior space, how the car handles and the comfort.

The MX-30 for us is the car to take when you have to drive to work or buy groceries and so on.

And now we are waiting for our main car. NIO ES7 that will arrive late this year.

But thanks again for the info about charging. How did you get the info about the charging problem and with GARO? Did you have this problem?

 

[AdnanSWE]

My dealer did the AM036A update on my car but I still have problem charging with my Garo chargebox.
I can charge all other cars on my charger but the Mazda stops after a while and says that it's fully charged. My dealer told me that they had updated the car with the latest update and blamed my charger so now im going to try to update the software on the charger.
So,I'll have to pay 200 euros to get a wifi adapter for my Garo charger to update the box and hopefully that will solve the problem.
But my feeling is that it wont and that I have wasted 200 euros to get a wifi-adapter just to update the software on my Garo charger, because it worked well with my Tesla Model Y i had before and other cars like Kia and Hyundai.

I feel that my Mazda dealer is not up to date and dont understand electric vehicles.

So, I'll keep you guys updated on the matter.

Thanks.

Hi, I am not familiar with this Garo charger. I looked up the manual online. That says you can connect with RJ45 (LAN) if the WiFi module is fitted..

So you don't have that and there is no USB either. So I would just take it off the wall, make an appointment with the company to let them update it.

Or, if this company doesn't want really bad publicity (from you..) ask them to come and put the WiFi module there, update it and take the Wifi with them.

So you pay for one hour for a service engineer..

 

[AdnanSWE]

Hi, I am not familiar with this Garo charger, but try to find out if it had a port or removable cover to get to a USB port. You need to connect the WiFi ;

look around the area where you connect that !

I have removed the cover and I need to connect a wifi-adapter and when I got the charger I did not think of getting it with wifi adapter because I could not see a reason for it.

Only way to update the Garo charger is to get a wifi-adapter.

 

[MX30_NL]

While you replied, I modified my post.. .. But if I where you, I would go to Mazda, and tell them that if you do what they say, and it still doesn't work, they also pay for the WiFi module !

Do you have a legal insurance ? They can write a nice letter for free, send it to the dealer with the lawyers letterhead.
The dealer will shit himself, and come with a solution that doesn't cost you a cent..

Anyway, you are also protected by EU-consumer law. Any 'durable' goods must be kept on a functional level by the producer, also the charger without wifi !

It is normal to update through a USB port, and you could not expect anything else. So if Mazda comes with a reply letter blaming the charger,

send that to the wallbox dealer.. .. play them against each other.

You can also involve the Swedish "ombudsman" who defends consumer rights, or if you are a member, the Swedish automobile club...

There must be thousands of Mazda's in Sweden with this problem. Your lawyer can blame "non-conformity" at Mazda and the charger supplier..

 

[AdnanSWE]

I sent an e-mail to a different Mazda dealer that I heard is more serviceminded. I hope they will be more helpful to my issue.

Thank you for all the great advice! I will see what the other dealer has to say about my issue first before I do anything else.

My idea was to contact Garo in the end to update my wallcharger if the issue is the software in the wallcharger. It still has warranty!

Funny that you looked up the swedish word for ombudsman 😂

 

[Hawke]

I sent an e-mail to a different Mazda dealer that I heard is more serviceminded. I hope they will be more helpful to my issue.

Yes hopefully he will be able to help you more. As far as I know the AM036A update is older and cars updated with AM036A, will still have issue with Garo as it is stated.

Did your dealer tell you which PCM calibration your car is currently at?

 

[AdnanSWE]

Yeah, I heard that too that it was an older update.
He didnt even bother to tell me because there was no cases for this problem in his system. I dont even think that he checked.
So he just blamed my charger for the problem.

 

[ASH8]

Just throwing this out there, the Dealer can only update what MDARS gives him as the latest at that time and date, if Japan later updates THE file in between a customer update then it is hardly the dealers fault.
And yes this is new for all dealers, remember most are selling 1 car a month if they are lucky.

 

[MX30_NL]

Funny that you looked up the swedish word for ombudsman 😂

I didn't look it up ! We had this institute as first, and the EU just adapted it to the whole EU.

Its the same word in any language I guess ( except French, they always want to re-invent the wheel)..

Even in Latin ( try it in google translate..) its "ombudsman".. .. in French its "médiateur"...

 

[MX30_NL]

And now we are waiting for our main car. NIO ES7 that will arrive late this year.

How will you charge that ? What model/make/capacity charger would need that ? Suppose you would need another wallcharger.. ..that solves the problem you have now as well..

Just thinking..

 

[AdnanSWE]

Nah, I had two electric cars before and it's not a problem. You dont need to charge every day. But yeah, that would solve my problem.
I could maybe get a Garo with two ports....😝

 

[AdnanSWE]

My problem is fixed! I'm charging at home now with no problem. I told the other Mazda dealer to update with this:
"TSB NUMBER: R077/22, First published to Mazda dealers on August 11th, 2022.

The MDARS Calibration File Part Number is
Right Hand Drive (UK)
MH10-186K2-J
Left Hand Drive
MH01-186K2-P"

And now everything is working!

I'm going to send an email to my first dealer that blamed my Garo home charger that they dont know what they re talking about and tell them about this update.

Now i dont have to pay 200 euros for a wifi adapter, because they told me do update my home charger.

Anyone ens that has this problem push your dealer to update with this firmware!

Regards
Adnan

 

[MX30_NL]

Congratulations !!

 

[Hawke]

I'm going to send an email to my first dealer that blamed my Garo home charger that they dont know what they re talking about and tell them about this update.

I wonder if they will reply!

 

[AdnanSWE]

I wonder if they will reply!

Probably not! Gave them a bad review on Google with the backstory and a good five star to the Mazda dealer that helped me!
