Mazda3 showing "Vehicle System Malfunction" but nothing specific

[lordshrooms]

2023 Mazda3 GT FWD

Randomly started getting this today and it seems like it's persistent. Drives fine, nothing seems out of ordinary.. just have that warning light. Mazda App also not showing any error codes in my inbox.

Recently did the transmission relearn thing from here:

and that made my transmission more responsive because it was previously a bit laggy. Also I have fuel milage around 13/14L / 100km which seems a bit high. My car has around 7700km on it and mostly city driven
Thanks

Any suggestions before I bring to dealership, i'll be going but they cant get me in till a cpl weeks. I also ordered an OBD2 scanner... to check for codes

edit: Also I have a dash cam hardwired to the fuse box from 2+ weeks ago, not sure if that would cause this

Maybe it's the battery. Try removing your cam wiring.

I'm getting a P05A0 DTC :O

If you say there are no DTC found, check the windscreen in front of the video camera ( forward sensing camera) for the traffic sign recognition system, it could be dirty. Check the radar sensor, maybe the badge is cracked, maybe a wire disconnected. On a second thought, where did you mount that video camera of yours? Behind the centre rear mirror? Access those panels and check for connections, maybe something is disconnected.

I'm confused. You stated "I'm getting a P05A0 DTC :O"?

I did not see (what?) the last line of the previous post. But then google search says that the code has something to do with the grille.

Apparently, there's a shutter that closes off airflow to the radiator in uber cold weather?

Yeah thanks guys. I am getting a DTC: P05A0(00) which googling means something wrong with the Air shutter grill? I took a look through the grill today and i see some leaves and stuff in there. I'm still going to take it to the dealership coz im still under warranty but hopefully cleaning it out fixes it

also I noticed i am getting much worse (average) gas milage recently: like 16/17L / 100 KM so maybe they are stuck or something.
