All repairs will be free of charge.

Following four reports for engine compartment fires in the United States, Honda is issuing a voluntary recall for approximately 1.15 million Accord models. Thankfully, no deaths or injuries related with these incidents have been reported so far.

So, what’s the defect? It’s the 12-volt battery sensor, which is located on the negative battery cable within the engine compartment and is monitoring the battery’s state of charge. Its only task is to signal the driver for problems with the battery or the charging system.

In the affected vehicles, Accords from the 2013-2016 model years, the sensor may not be sufficiently sealed against moisture intrusion and, 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.” If that happens, the sensor could heat up through electrical resistance, start to smoke and, in the worst case, start a fire.

By late this month, Honda will start notifying owners of affected vehicles about the recall and send them instructions to get their cars to the nearest dealer. In the service center, the vehicle will be tested for a Diagnostic Troubleshooting Code (DTC) related to the sensor, and the battery sensor will be inspected. If necessary, it will be replaced free of charge.

The Japanese manufacturer explains that, due to the large number of parts required for such a massive recall, if a vehicle has a battery sensor in good condition, the dealer will apply only a temporary repair. Eventually, all owners of vehicles that have not yet received the final repair will receive a second mailed notification with instructions for a new visit to the dealer for the final repair.

Statement by American Honda Regarding Battery Sensor Recall: 2013-2016 Honda Accord

  • Approximately 1.15 million Accord vehicles affected in the United States
  • 12-volt battery sensors will ultimately be replaced, free of charge
  • Four engine compartment fires have been reported in the U.S. with no reports of injuries

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.

Honda will notify registered owners of all affected vehicles by mail beginning in late-July 2017, with instructions to take their vehicles to a Honda automobile dealer. The dealer will check the vehicle for a Diagnostic Troubleshooting Code (DTC) related to the sensor, test the battery sensor and, if it is not functioning properly, replace the sensor with a countermeasure part (final repair). Due to the large number of parts required to conduct the recall, if a vehicle has a battery sensor in good condition, the dealer will apply a temporary repair – application of an adhesive to the battery sensor case to prevent moisture intrusion. When countermeasure parts inventory becomes sufficient, all owners of vehicles that have not yet received the final repair will receive a second mailed notification advising them to take their vehicles to a Honda automobile dealer for the final repair.
