On Friday, Honda said they would recall roughly 2.1 million vehicles worldwide to replace battery sensors due to the risk of fire. The spokesperson for the Japanese automaker, Chris Martin, said the recall would include 1.15 million Honda Accord vehicles, with the model years ranging from 2013-2016 in the United States and almost 1 million elsewhere. Roughly 52,000 vehicles in Canada will be recalled. The company reported they have received four reports of engine compartment fires in the United States and at least one in Canada. One thing in common of these reports, is that those areas commonly use a lot of road salt during the winter. Zero injures have been reported.
The recall is to replace the 12 volt battery sensor which may not have been sufficiently sealed against moisture intrusion. Over time, moisture may introduce road salt or other matter into the battery sensor, which may lead to rusting and eventually lead to electrical shorting of the sensor. Due to the large volume of recalls, Honda stated the dealers will initially adopt a temporary fix by applying adhesive to prevent further moisture intrusion and then when supplies are available, replace the whole sensor unit. The first report of a engine compartment fire was from Canada in 2015 and the company had begun to investigate the issue. A similar fire occurred in China in early 2016. Honda had introduced a redesigned battery sensor mid 2016. The company said the occurrence rate of the engine compartment fire is estimated to be low, but will continue to probe into the matter.
