There have been reports from the Mazda MX-30 club on Facebook that indicate the batter heater is not working correctly. At least one car was towed to a dealer.

It seems that the battery is getting so cold the car throws a error message saying "EV system Malfunction have the vehicle inspected"

At this point the car will not drive.
outside temperatures ranged from -5 to 0. Hopefully this is a software issue not hardware and will be fixed quickly.

Anyone here have a working batter heater ?

Thanks

I'v been using the car in temperatures between -7 to +5 C since I got it and I have seen no indication of the battery heater ever starting. That may be normal but I did once get a message that the battery was too cold and the acceleration had been limited.

Yeah.... I have yet to hear from someone who has had the battery heater working. If the heater is doing it's job you should never see a message saying its too cold.

Did you happen to tell Mazda ? If so what did they say

Not contacted dealer yet, going there after weekend with this and also now its been 2 month since I pointed out the rattling noice behind the cover to the driver seatbelt attach point and the rear side airbag and they have yet not come up with any solution. Patience running low..

I know about the rattling but what is the issue with the rear side airbag ??
Ah, sorry, was unclear. Ment the rattle comes from that plastic cover that also hose the rear side-airbag behind it. Hopefully the loose part in there has nothing to do with the air-bag itself. Its all in the rear door.

Ah okay ! I will be getting a RHD model so I am hopeful there is no rattle and if there is it is on the pass side and not the driver haha. I don't have issue pulling the cover off myself and putting something on the metal if the dealer is unwilling to provide a fix.

It looks easy enough to take off but I don't have the car yet so I don't know for sure.

Hopefully they help you. It's a bit sad to see they have not as of yet

I picked up my new MX30 today here in Norway at -20c. The car was still in the showroom, so the battery was warm(ish). Drove it home, charged it in the garage at -17c via the Mazda App, and no sign of any battery heating up. Went for a short drive and it was using around 55Kwh per 100km. Our 64Kwh Hyundai Kona used 16.7Kwh for the same trip! Personally I don’t think the heater is working looking at the high energy consumption.

Oh wow what kind of range would you expect with that kind of consumption ?

Definitely let you Mazda dealer know !!

This brings me to my ultimate question, and the dealer couldn’t answer me. When I preheat my Kona it also warms the battery as well as the cabin. Whilst plugged in, it uses the power from my wall box and not the main battery, and as a result I only lose about 1km of range. The Mazda so I was told today uses the power from the battery and NOT from the wall box. What’s the point of leaving it plugged in? I lost about 8km of range and the battery went down from 100% to 97%.
That, coupled with a car that has a small range is quite a lot in my opinion.

Sounds a bit like what the id.3 drivers are dealing with.
So pre heating the car when plugged in is effecting the overall range ?

Basically both cars (Kona and MX30) have a heating pump. This should warm up the battery and cabin efficiently. Preheating the car when away from home and NOT plugged in uses a lot of battery in very cold weather, therefore reducing the range.
The Kona’s EV system is designed so when you’re heating the car when plugged in will NOT use the car’s own battery, but use the power from the wall box, therefore not using up valuable range. With the MX30 you are using the car’s own battery power to heat up the battery and cabin even when plugged in. Why on earth have they designed it that way knowing that the car has such a small range? I bought the MX30 a few hours ago and I’m already regretting it. Anybody else living in a cold climate and feeling the same?

Solution of consuming battery is strange, but workaround is to activate charging after activation of heater.
Ps. Heater is not warming up battery and every day morning I have a popup saying temp too low, driving power limited....but to be honest do not feel anything being limited.

The car has been in the garage for more than a week (plugged in) but haven't driven it as it was -15c. I had a message come up on the App saying to switch the battery heater to the "off" position when the car isn't being used!! Why??? I heated up the car today using the app and I had 168km of range (with cabin heating off) and 100% of battery. After it had heated up I lost 2% of battery and 6 km of range because it didn't use the power from the wall box. It used the power from it's own battery. Why did Mazda design it that way? Our Kona loses about 1km when warming up and uses the wall box in our garage and not the battery to heat up the car. In countries with milder conditions it's not a problem, but here in Norway losing 6 km of range and 2% of battery is a lot to lose on a car that can only drive 142km with the heating on.

Is it ? I can't see how losing 6k would change any kind of trip lol. Also why would you want the battery heater running if you're not using the car for awhile

You have a point, but my argument is that of our 3 previous EV's they all used the wall box for heating the car and battery, whereas the Mazda doesn't. Having the lowest range they could have designed the car to use the wall box. 6 km loss may not seem much to you, but our other EV's didn't lose any. Judging by the flag I take it you're Irish and live in Ireland? If you do, then I reckon you get around 200km without the heater on?
Here in Norway I get 162km without the heating on and 145km with it on. I still say that Mazda could have built a slightly bigger battery rather than put in a range extender for the near future.
Mazda have contradicted themselves in saying that the small battery is more environmentally friendly to produce and that the range is adequate for the average daily commute.....Then they say that they will put in a petrol driven Wankel engine to get a longer range. I thought we're all trying to get away from fossil driven cars! :)

Using the car battery instead of the wallbox is very dumb. No clue why Mazda did that.

As of now I get Zero because I am still waiting on my MX30. Before buying the Mx30 I assumed I would only get 109km per charge and made sure that was enough to suit my needs. Anything over that will be a bonus for daily usage

Range extenders in general are very stupid. My main reason for going EV was to ditch needing to do oil changes and worry about up keep on a ICE ha

....sorry, there seems to be some text missing? Did you mean to say 109km or 109 miles? I think the latter is what you meant :)
