I'm having a cruise control issue, again

I like the have the cruise control activated permanently, so when I hop in the car and drive off, all I have to do is hit set. For some reason when I start the car now, I have to re-activate CC, ie the icon is not on the dash until I hit ON. Got no idea why it keeps turning itself off.

This was happening prior to the 1000km service, were it came good just before the car went into service. So Mazda could not find an issue. Last night issue came back again. All I did was change the night brightness of the center display.

Got any ideas anyone?

According to posting on the German forum this has been solved by latest update of the VCM module to version DFR5-66S01-J Don't know whether these update versions are region-specific though.

Thanks Ronnie.
I'll pass that info onto my local dealer.

Could you forward me a link to that particular thread, please?

Sure, here you go: Diskussion zum Firmware-Thread - Mazda CX-30 Forum for confirmation. The "announcement" of the update itself is here: Firmware Thread CX30 - Mazda CX-30 Forum

Many thanks Ronnie.
Makes for interesting reading, with help of a translator

It sure does, lot's of knowledge there. Confronted my dealer couple of times with TSI/TSB numbers for problems of which they claimed there was still no solution .

I had the same with my local General Motors / Holden dealer, a few years back. They hated me reading forums and finding info they didn't know about or weren't willing to do.

Can confirm myself that the VCM update (which together with 11 other modules was performed this week on my car) has indeed solved this problem. Also a changed distance for the radar cruise is stored now.

That's great news @Ronnie.
Hopefully my dealer will pull their finger out and do the update.

I changed from dealership to a certified Mazda workshop (where my former Mazda had been maintained as well) to get it done, was fed up with their unwillingness to provide this after sales stuff which they can't invoice Mazda for.

Finally, after many moons and visits from me, my CX-30 had the BCM updated today. Seems issue has been fixed. Same with the cruise distance too.
I asked if any other module was updated but they said BCM only.

 

[Ronnie]

Well, whatever they did or didn't update, glad it got fixed .

Sadly the issue is back, only a week after firmware update I'm thinking it's a faulty BCM.

Vehicle was faulting when I took it back to the dealer again. They kept it for a few days to examine and raise a tech case. Got it back as it's a long weekend here so nothing can be done, and all is good so far. Maybe them looking/reading the BCM did something. Anyways, going back for further investigations.

I would then insist on having the VCM updated. And when they have the laptop connected anyway, any module update they can find.
