"Rear Left Malfunction"
Got this while on the road:
"Rear Left Malfunction"

When parked in the garage, it started alternating b/w "Rear Left Malfunction" and "Rear Right Malfunction".
Any ideas?

It's an airbag issue, most likely loose wire.

You could look underneath your seats and see if there might be any loose connectors right around the wire looms. Good luck!
