I had one of these in with a similar issue and sometimes a power latch fault code st I red and other times no dtc's logged.

I narrowed it down to a poor battery state of charge even though the battery wasn't that old but constant short trips didn't give it much chance to recover from stoo starting etc.

fitted a better quality battery and all seemed well. Also I remember replacing the brake pedal switch (passenger side) as iirc abs logged this code.
