Charging System Malfunction...

So I walked up to my car 2 days ago, get it, put my foot on the brake and push the button and to my surprise it wont start...

Im going crazy thinking of why it wont start and why the start button is flashing green. I know the car is brand new, just about a week old so it shouldn't be having any issues. I remembered reading somewhere in the manual something about holding the key upto the button and pressing the button if the fob is dead or if there are issues with the fob. After doing that the car starts right up and I get the following screen...

Anyone know what this is about? I immediately turned the car off and turned it back on, but it came up again. Ultimately I ended up just driving it to work without a problem, but still scratching my head as to why this came up...

Do you have the iEloop system on your car ? Do you think the message is related to that ?

that is an alternator problem, or a system glitch where the fob battery was low n ur car went crazy. regardless it is wise to take it to the dealership, since you have a picture to prove it. trust me you dont want alternator problems on a brand new car. Also if your car is a s Grand Touring with i-eloop system, then that could be a cause too...

Finally got some time to take it in today. They decided on keeping the car overnight, I'm taking the 2nd key fob in tomorrow. My dealership seemed to make this a very urgent matter, as they got on the phone with Mazda N/A pretty quickly.

They got me a loaner, but its not even close to my model... I forget how spoiled i am in my new car...

Just had the same warning pop up on my 2014 mazda 3 while driving it out of the driveway. Turned car off. First attempt to re-start had no response if any kind (no indication of any electric power if any kind. Second attempt car started up fine. Several re-starts during the same day also fine. Went to the "warning guidance" application on screen and it said no warnings found?

What did the dealer ever find with your car?

I just got the same warning today after leaving the car sitting in the parking lot (5 degree F) for about 9 hours. But the car started without any problems.
I went ahead and drove home after works anyways...
After I got home, i turned off ignition and fired her up again... dont see the warning anymore !

I guess it just needs the firmware update.

When I first got my car, my dealer said if it sit a long time and the battery is low, it will do this. ESP after a long storage. He said there was a dealer note about this hope this helps. Cold weather too.

My wife's car got the same exact warning message today. While she was driving to the dealership the battery warning light came on. The car is at the dealership now being looked at. I don't see where anyone has posted what the cause of this warning is, other than firmware. Any known fixes? Thanks

I just got this screen today. No problems other than the screen.

I do have the I-loop system and was driving through puddles in down pouring rain. I called Mazda and had the car towed.

As for infotainment system update, I just had mine done two weeks ago and they said bring it back in a week for version 29. I'm hoping an update and the current service recall fixes my problem.

Bet ya, your belt is slipping and the alternator is not charging because of it. Even though you may not have the iEloop in your 3, there is a problem with slipping belts. Either you went through water, was driving in the rain.

I think that now is spring, and the rainy season is coming, you will see a lot more of these non charge issues. low battery. Error can come and go without notice

Why do people always assume it's new and has no issues? The first issues you have could pop up before the first oil change. It can happen when they are producing this cars. It is probably for the i-loop brakes. There is a issue with the program that controls them. If it gets slashed with to much water the computer shuts it down? I believe that is what I heard. That could be what the problem is. Or you have a defective power system in some way and Mazda will fix it under the warranty

No it the drive belts. there is a spot under the car that just drinks up water like crazy that the belt slips and cause a charge error and then shuts down iEloop.

this is serious stuff and I cannot see why mazda is dragging on this. It could shut down in some case while driving on the freeway. NTSHA will get on their buts if any accidents comes from this.

I just got the same alert in my 2016 Mazda 6 two days ago. I had a dead battery, I replaced it ($178), 4 days later I get this intermittent alert. I took the car to the dealer yesterday and they said everything looked good except there was a 10ohm reading between the battery connection and the "generator". $286 to replace, they ordered the part, today they removed the original harness, checked it again and now it looks good? They are now recommending to replace a second harness (because that's what the diagnostics are pointing to) at a cost of $4k+! The car is barely over 3 years old and I'm upset. I asked them to put the harness back, I'll pay the $73 diagnostic fees and look at it myself or taking elsewhere for a second opinion. Frustrated.

I took the car into Meinkie and they found that the 13v output from the alternator would drop to less than 11v when the car had it's headlights, radio, and air conditioner all on at the same time. That would trigger the intermittent alert and they recommended that alternator be replaced. We did that and so far so good.

My 2014 CX5 just started giving me this warning intermittently. It seems to happen when going up hill and hitting around 3000 rpm. It only stays on a few seconds though. I have replaced the battery since that was bad, got rid of corrosion on the terminals, and tightened the terminals, but I am still getting that warning. I haven't had any issues with the car starting since replacing the battery and have never had it turn off on me. I should note that this is the 2nd battery I've replaced in 2.5 years. Any ideas on what could be happening? It isn't throwing any codes on the code reader. I thought they tested my alternator when replacing my battery, but I'm not 100% sure.

My OEM battery lasted for about 3.6 years. The summertime heat can be very harsh on batteries. I'm told that more batteries are killed by excessive heat than excessive cold.

That said, you might want to install a voltmeter to make sure the alternator is keeping up with the proper voltage; eg, about 14 volts or so when the engine is running. A Scangauge can show the voltage and a lot of other interesting things as well, including water temperature. Carmakers nowadays seem to think their customers don't care about monitoring such things. I do.
