Honda and Daihatsu have decided to recall some 5 million cars globally to replace potentially deadly airbag inflators made by Takata.
The move comes just a day after rivals Toyota and Nissan said they would be recalling 6.5 million vehicles over the same issue.
So far, the six deaths linked to Takata airbags have all been in Honda cars.
In April, Honda cut its profit growth forecast after missing the mark last year on recalls and other issues.
Honda said that the models affected included the Fit subcompact and would not affect its cars sold in the US, where most of the deaths occurred.
It plans to use replacement parts supplied by Sweden’s Autolive, Japan’s Daicel and Takata in the recalled cars.
Daihatsu, meanwhile, said it would recall the Mira minicar.
Other than Honda, all other carmakers said the recalls were precautionary and no accidents or injuries had been reported.
Investigations did show that Takata airbag inflators were not properly sealed and could be damaged by moisture. It is alleged that the airbags can burst under pressure, spraying shrapnel inside the car.
The latest announcements bring the total number of cars recalled because of Takata’s airbags to about 36 million since 2008.
The car equipment maker faces multiple class action lawsuits and criminal and regulatory investigations in North America.
Following the latest recall, Takata’s shares were down 5.6% in Tokyo.
The National Highway Traffic Safety Administration (NHTSA) has expanded a recall of vehicles with potentially dangerous Takata airbags to 7.8 million.
The NHTSA warned that owners should take “immediate action”.
If deployed with force, the airbags have the potential to eject deadly shrapnel at passengers.
The NHTSA has identified 10 manufacturers who used Takata as a supplier, including General Motors, Honda, and Toyota.
The agency has told those who might own affected vehicles to check the list at www.safercar.gov, and specifically warned those living in more humid climates such as Florida and Hawaii to get their vehicles inspected.
“Responding to these recalls, whether old or new, is essential to personal safety and it will help aid our ongoing investigation into Takata airbags and what appears to be a problem related to extended exposure to consistently high humidity and temperatures,” said NHTSA deputy administrator David Friedman in a statement.

Initially, the NHTSA said that only 4.7 million cars could be affected, but it has increased the number of vehicles twice in recent days.
Japanese supplier Takata warned recently that older airbags could explode with too much force, which would send plastic and metal parts towards passengers with enough force to injure them.
Takata said it estimated that around 12 million vehicles around the globe may contain the parts.
The recall notices have been ongoing for the past 18 months, but regulators and car manufacturers have warned that only a small percentage of those cars potentially affected have been returned and inspected.
The majority of the affected vehicles – more than five million – are Honda cars manufactured between 2001 and 2011, including the Accord, Civic, and Pilot models.
