My Accord Hybrid Touring is 2015., bought it used from Honda in 2019 (one previous owner). 12V battery was replaced at that time by the dealership.

I saw this message during this winter on two occasions, both time in subzero temperatures with salt on the road (Toronto, Canada). Next day it was gone.

Searched web and found following recall:
"Honda will voluntarily recall approximately 1.15 million Accord vehicles from the 2013-2016 model-years in the United States to replace the 12-volt battery sensor, free of charge. Honda has received four reports of engine compartment fires in the United States related to this issue, all within the “salt belt” area. There have been no reported injuries related to these incidents.
The 12-volt battery sensor is located on the negative battery cable within the engine compartment, monitoring the battery’s state of charge in order to alert the driver to problems with the battery or the charging system. The battery sensors installed in affected vehicles may not be sufficiently sealed against moisture intrusion. Over time, moisture intrusion may bring road salt or other electrically conductive substances inside the battery sensor, leading to corrosion and eventual electrical shorting of the sensor. A shorted sensor can heat up through electrical resistance, potentially resulting in smoke coming from under the hood or, in the worst case, a fire."

I checked on-line and it seems it does not apply to my VIN.
However, it makes me nervous that what I see matches the recall description, so I plan to go to the dealership and replace the sensor.
No idea how much would it cost.

Anyone has similar problems or any useful info?

Thanks!

When my 2014 was still under warranty I had intermittent 12 volt system faults. It took two visits to the dealer to have them figure it out - I had to video the errors as they’d come and go and I found nothing on the net at that time.
if you’re concerned, it’s easy to replace and costs about $30-$50 new for the part.
