2018 mazda3 - multiple warning lights at once ?

[starwind]

Hoping someone may be able to shed some light on a preplexing problem I encountered today, which seems to have at least for now resolved itself.

2018 Mazda 3 Sport GT with premium and tech packages. Bought from Mazda of Toronto (thank you, Jeff!), it is 7 1/2 months old with 5160 km [yes I have a very short commute]. I live in Ottawa, so we are just coming out of a proper winter and it still has its winter tires on it.

It has been raining all day today and is still raining [not sure if that is relevant].

Today coming home from grocery shopping I turned onto my street and my dash suddenly lit up with multiple warning lights. According to the infotainment centre warning light information screen:

DSC malfunction
BSM malfunction
TPMS malfunction
MRCC malfunction
SBS malfunction
DRSS malfunction
SCBS malfunction

For a brief while there was an 8th, but I did not catch what it was.

I pulled into the driveway and parked. Turned the car off and on a few times and they were all still there. Drove around the very short suburban block, still there.

Put car in the garage where it sat for about an hour. Turned car on again. All 7 still there.

Drove around the longer block. 6 disappeared and a NEW one added:

HBC/LAS system malfunction
SCBS malfunction

Turned car off. Turned back on. ALL GONE.

Any suggestions on what could cause this disturbing weirdness ?

Thanks !

I might be inclined to check the battery terminals and make sure they are properly secured. It sounds like there was either a voltage drop or an interruption of the vehicle network for one reason or another. Has the situation the recurred since then?

No it hasn't. Some of the same lights come on briefly when the car is started but after a few seconds go out. I had never noticed that before but since I am paying attention to any lights showing up now I am not sure if they did it before or not. But they do go out pretty quickly -- faster than the infotainment sysytem takes to activate.

sounds stupid but make sure the windshield cam is not blocked/fogged/dirty

also its a 2018 so take a picture of it and bring it to the dealer , it has full warranty. see if there are any stored codes that they can fault trace
