So, despite my optimism with the car’s little problems, today was finally the day where things got serious. Just arrived home after almost 4 hours on the side of the road.
After having my shocks and stabilization bar replaced on Monday and having the fuel tank problem looked at, today when returning home after work, doing like 50 km/h in EV mode, a sudden red message alerting to failure on the hybrid system and electrical leak detected on the hybrid system and a couple of other orange messages. Thinking it would be one other situation of shutting the car off and on again, so I did, just to find out it would light everything up but the messages kept showing and never the car fired up again. Not EV, not ICe, nothing. I could disengage the parking brake but was stuck in P in the shifter. Called Mazda 24h assistance and a trailer was dispatched. Meanwhile tried disconnecting the 12v battery for a few minutes but when I connected again nothing changed.
Thinking that was a case of getting it to the trailer and off to the mechanics but boy was I wrong.
Trailer came, tried to start the car doing the exact same things I did. Nothing. And then started the problem of how do you load a car with 4 wheel drive, stuck in P, into a trailer. You don’t, at least on it's own wheels.
Trailer number 2 came to the rescue. After some talk they were not sure if they could use the little wheels on the cars tires because of its weight. Solution: find a way of getting the Mazda chief of mechanics from our city to get to us with the machine to connect to the car. Don’t forget it was now 21h30. Eventually he showed up but the car just refused to let him connect to it. He tried everything but the car wouldn’t let him connect. Something related to low voltage but not from the 12v battery because, just to be sure, he even connected it to the booster and it wouldn't work. Back to the wheelies. Eventually we got the car into the wheelies and with very gentle movements loaded it into the trailer and is now quietly waiting in the Mazda shop until they open tomorrow.
The mechanic thinks it will be for sure something with the high voltage system because all the other parts seemed to be working correctly. Let’s see. I’ll let you know once I know more.
Ps: although a very unpleasant night, everyone involved was great in trying to get this beast off the side of the road. Even getting the mechanic to come to us with the tools and computer at that time of the night is something I would never get in BMW before. System language is Portuguese

Did you have anything plugged into USB ports at the time of this failure?

 

[mruisilva]

Hello. Maybe I had my iPhone charging through USB

 

[Chris_Z]

There is a report on YouTube (in Japanese - you need to use CC + Autotranslate) which describes how an experienced car mechanic actually inadvertently bricked his CX-60 - via USB-C port!
The good news is that in the end it all were recoverable.
The melt-down was caused by an interference from USB-connected "something" with in-car network known as CAN-bus (OBD II) fooling some on-board computer which decided that something unauthorized is happening, and the car immediately activated its entire arsenal of anti-theft security and disabled almost everything.

Maybe somebody who is fluent in Japanese language can extract more details from this video, I could misunderstand something.

 

[mruisilva]

Thanks a lot for your help. Don't really know anyone that speaks Japanese but I'll try to get this to the mechanics and at least lead them into some direction

 

[Chris_Z]

Messages on the display indicate an electric short-cut.
It sounds to me like some physical electric connector got loose and touched something connected to the electric ground.

Dire warning is because you have an extremely high voltage involved.
It's no different to systems protecting all electric equipment in modern houses.

I hope your dealer have an automotive electrician on call.

 

[mruisilva]

That was the opinion of the chief mechanic that came to the rescue after trying repeatedly to connect the car without luck. He said something about some hire with "mass" (???) or touching something in the area of the high voltage battery could be the problem. For that reason the car activated all securities and wouldn't let him in. He said for sure they would get it to work again but wouldn't let me have it until they know exactly what caused the problem

 

[mruisilva]

Abou the video: this mechanic might have done a video previously that really upset Mazda and spends the time apologizing for it

Mass = Ground = Negative (-)

Different names for the same thing

Well, at least concerned .
The guy just loves experimenting, he is more engineer-scientist type than mechanic, he discovers some shortcomings and suggest improvements.
I get a feeling he respects Mazda very highly, so he is in pain if something is not perfect.
He comes across as a very sincere fellow.

 

[mruisilva]

For sure. That's the feeling I got watching the whole video.

I don't understand anything of this technical part. I'm just an interested user seeking to solve my car's problem but after watching the entire video I think I'll wait until the Mazda mechanics have a say on what's happening. Don't want to have them thinking I connected something strange in my USB port and try to blame me for the problem.
All updates to the software was done in their shop through their machine. Although I saw in this forum some users offering to send the files for the updates if we wanted to, I never did, exactly because I was afraid of doing something wrong in the process

These updates seem no different to the ones Mazda shop performs, and even Mazda can not tell any difference once they are (correctly) applied.
The problem is that Mazda have a policy that they don't apply anything unless you explicitly ask them to, and you can not ask them if you don't have the particular problem.

I'm an IT-guy, so for me, it's all very straight forward (until I make some mistake 🤓), but I appreciate that the procedures themselves, no matter how clear being described still can be quite confusing for non-technical people. One day, we will have self-updating Mazda vehicles, but this day is not quite here yet.

In other words, you absolutely make a perfectly correct decision by not attempting anything which you don't fully understand all the implications of, and especially where there is ample room for normal human mistakes.

Just found out in a Facebook group of UK CX60 owners some other people with the same problem.
One just happened today and the other, also from Portugal, had the same and they tracked it to be a faulty part in the battery cooling system. Had the car in their garage for 4 weeks. Hope mine is quicker and the solution is permanent and not just a few weeks until the next breakdown.
Calling the mechanics that handled that car tomorrow to get some more details

hello, I'm French and I called Mazda assistance because I had exactly the same problem last night (a Sunday of course!). I am waiting for information from the garage and on your side do you have any news? it is fixed and how? THANKS

 

[g.prajeesh77]

I had the same problem In Denmark and they replaced the heat sensor
Now the car is back

 

[mruisilva]

Hello Pete.
Sorry to that you faced the same problem.
I stopped by the garage today to see if they had any news and I know the car is now working and they've driven it without faults. According to the chief mechanic they're waiting for Mazda Europe response on the service bulletin they opened befogging delivering the car to me. Apparently it was software but once I'll go there to have it delivered I'll make sure to know exactly what the problem was to be sure it's safe to drive it. Once I know this I'll let you know. Good luck.

Hello. I'll make sure to pay attention to what the solution was on my case

Thank you for your answer
I also think of a software problem: my cx60 (like many others I think) has its little "moods" from time to time! example: just before the breakdown I had, when I was just passing another vehicle, a big message "BRAKE!" (luckily "she" didn't brake for me!) and, just after, some others I-ACTIVESENSE warnings . It's really becoming painful with all these little bugs and now this one (he's a big one!) where all the engines stop in the middle of the road, it "stings" when it happens...

And I'm not talking about my wife !!! my WAF "Wife Acceptance Factor" is largely exceeded !

How I understand you.
My car sometimes does the same (BRAKE message) normally if a car is parked in the side of the road but still with a little bit inside the road. Normally it senses I'm already controlling the situation with the steering wheel or the brake and doesn't do anything but sometimes it applies the brakes heavily. Never having had similar systems in other cars I just think of it as something necessary because it's not a person but a computer analyzing static facts. "I see something on the road, the brake is not pressed by the driver, then I alert him and press it myself if we approach to much"
Now that we speak about this, the car did one this braking moments (1-2 minutes) before it showed the red alerts. Not sure if can have any relation but... Let me see what the Mazda mechanics have to say when they deliver the car to me (whenever that happens)

strange, indeed ... i will let you know as soon as i know more about this engine failure ... I hope soon !
