The Japanese manufacturer reports that affected vehicles could have an improperly manufactured battery sensor, with gaps that could allow for moisture intrusion.
If the condition occurs, moisture containing conductive substances (such as road salt) could enter the battery sensor, causing an electrical short and potentially a fire.
Both the 2.4-litre and 3.5-litre versions of the Accord are affected by this recall, though there have been no reported incidents in Australia. A similar notice has been issued in the US, with around 1.15 million vehicles affected.
Owners of the affected vehicles will be contacted via mail once parts availability is confirmed, and will be advised to present their Accord to their local Honda dealer to have the battery sensor inspected and, if necessary, replaced.
