Honda is recalling 4.89 million more vehicles globally, and Daihatsu has about 260,000 to repair in Japan, according to Automotive News. With these latest expansions, all of the affected automakers have needed to fix about 36 million vehicles globally for these faulty airbags since 2008. Some of the first instances of these problems were found in an Isuzu campaign in 2001.
This latest round of recalls was sparked by a study from Takata that found the inflators' propellant could be affected by moisture over time. While the automakers received this information in March, it took time to determine the number of vehicles in need of repair and where they were located, according to Automotive News.
To make sure all of the affected vehicles in the US are repaired in a timely fashion, the National Highway Traffic Safety Administration is reportedly considering a strategy to force things to speed up. Honda and Toyota are already using outside suppliers for the parts they need.
