According to Reuters, Honda decided on this recall expansion after analyzing 1,000 inflators from vehicles not previously covered by its campaigns. The company found that the density of the gas-producing chemicals varied in them, which could cause a safety problem in the future. The models affected include foreign versions of the Fit and CR-V with production dates between 2007 and 2011, the Associated Press reports.
Research suggests that Takata's inflators can be affected by exposure to moisture. This can cause the propellant to ignite too quickly and the component to shoot metal shrapnel when the airbag deploys. The issue has been linked to eight deaths worldwide, and there was a recent report of the issue causing a vehicle fire in a Nissan in Japan.
The global inflator recall has had serious affects on Honda's books, as well. The Japanese automaker recently had to revise earnings from last year to account for an extra $363 million in costs from the campaigns and has been dealing with lawsuits over the issue. To improve quality, the company decided not to set sales goals through at least 2017. Honda last expanded the recall in Japan in late May to cover another 340,000 vehicles. It has also been searching for Takata's inflators in junkyards in the US.
