For a month or so now, I’ve been getting intermittently the three following errors on startup:

1. EV system malfunction: have the vehicle inspected
2. Airbag system malfunction: have the vehicle inspected
3. In-vehicle network malfunction: have the vehicle inspected

It’s not on every startup, just sometimes (once a day maybe) and there doesn’t seem to be a pattern as to when it comes on or not.

I’ve taken it in for the recall and the dealership did some jiggery pokery to the computer but they have returned (or not gone away!)

Anyone else experiencing this?

No sign of it on my car....yet. Could you reproduce it at the dealers?

What is your cars 12V battery voltage ?

I think there might be a fault on your car's CAN bus, something like a node operating out of spec or a loose connection, causing spurious data to be received by the computer.


-Edit- My thinking is that something is corrupting messages on the bus. Normally corrupt frames are rejected by the transceiver, but I remember that the CRC on a CAN bus frame is only 16bit, so it's possible that a corrupt message might be getting through every 65536 frames or so (the actual error rate will be much lower, but the number of messages is very high, so I give a numerical value to illustrate the point)... The computer will then flag the device sending the corrupt message as faulty, but the device is probably fine and it's the physical layer that is faulty. I've has this type of problem on simpler serial busses in the past, never on one as robust as CAN, but it's worth investigating.

As kopaszkrapek states check 12v battery status first. This may sound weird but check esim signal status on radio screen bottom right far right signal box as per picture. Spurious communication can cause weird effects as can low 12v battery. If that all checks then as h5n1xp states there may be another issue that only the dealer can diagnose.

Saw the EV malfuction today. On the way home it did not show up anymore.
I did get the updates 035 and 036 already last month.

 

[Thebriggie]

When my 12v battery ran low recently is showed all kind of error messages until the charge was restored. Could it be the journey was enough to top it up? Once driven the errors eventually go.

I believe the main candidate (genuine repeatable car s/w or module fault aside) is low 12v battery with low esim signal and poor gps signal (in car communication error please contact your dealer is shown) also outsiders as they can also create error messages

Any indication of anything else on the dash apart from the central white text with orange alert?

Without a repeatable problem it is difficult to pin down as you no doubt know.

With this car nothing is out of the question... 🤯

No EV error message today.
I had 3 bars on battery, but only one bar in signal strength, which I foolishly thought was referring to my mobile phone.
I charge the car almost every day, so I assume the 12v battery is charged too?
(EDIT: apparently not, it charges while driving or having the car "ON".)

 

[Thebriggie]

Remember the 3 indicators are phone battery, phone signal and esim signal. The 12v battery state is not displayed anywhere except in hidden maintenance mode screen

Alan

 

[bassek]

OK. I had my phone in my pocket. 🤭
The most right horizontal bars are for the esim of the car?

 

[Thebriggie]

Correct. I had to leave my phone in the house then fetch it out to double check it as I was doubting myself for a second there! If esim signal is weak it doesn't help. To check 12v without actually measuring see the link below

Service Mode

A handy procedure to enter the Mazda MX-30 Service mode. -Easy to check vehicle status, features, equipment, software versions, or your 12V battery charge level without any tools. Press and hold the Volume/Mute button, then press and hold the Music and Favorite buttons at the same time for 5...

Yep. My 2022 just started with that message. And it started the day after I picked it up from the dealer from having a oil change and wheel rotation. What is this !! Ugh. My last car was a lemon. Please let this be something easy.

Apologies, did you say “oil change”? Is that some colloquially generic term for car servicing in the States?

Yes, I’ve had EV error message come on three times now and each time the car drove fine but the annoying warning remained during driving and start up.
The technician at Mazda told me it’s because I depressed the go(gas?) pedal at the same time as the brake and he needed yo hook it up to ‘reset’ it. Each time $30
There must be a hack for this or some way to disable this warning! Anyone?

 

[Thebriggie]

Did you depress both at the same time? I always drive with one "active foot" so this has never occurred in all my years of EV driving. The car doesn't expect both to be depressed at the same time so the car may think there is a fault hence the alarm and no override facility.

If the answer is no then you need to inform the dealer accordingly

Thanks Alan, you have concluded correctly that I must have depressed both at the same time. My situation is as a paraplegic, I have hand controls on the car and the two functions are on the same lever. The initial set up was extremely sensitive between the two functions and it happened within a couple days of driving. This time it took a few months to happen. I will certainly do an adjustment to make more differentiation between the two motions by adjusting the controls but would like to have a way to reset it without taking it to the dealer to be reset. So, I’m assuming no owner can reset his own car warning system without service?

 

[Thebriggie]

Given your circumstances I would ask the dealership if they can provide any assistance in disengaging the feature. I honestly believe if you do it on the foot pedals it alerts and then goes off but I would need to check it and get back to you. So perhaps the car conversion has created this issue?

Alan

 

[Thebriggie]

I get this error and then it goes off when I drive on.

There is an auto shut off of Engine (Power) on all cars including MX-30 if both the Brake and Acc Pedal are depressed at a certain degree.
And action will also store a DTC P2299, this is not a fault but a safety feature implemented about 13 years ago on all new cars to stop run away accelerating and uncontrollable cars (remember the consumer outrage in 2010 when a Lexus with I think 4 people inside car was out of control and driver was on phone to 911 and could not stop SUV, sadly it crashed and all were killed).
This safety feature can not be disengaged.
