As sure as the sun rises in the morning, we can always count on the Takata airbag recall adding new vehicles to its ranks. General Motors is poised to add another 5.9 million vehicles to the list after the National Highway Traffic Safety Administration issued an announcement on Monday.

Regulators stated that the automaker will be obligated to recall SUVs and pickup trucks (GMT900 vehicles) manufactured between 2007 and 2014 because the installed airbag inflators suffer from the classic Takata trait of being extremely dangerous. While the defect itself is relatively rare, the number of vehicles involved is staggering. Around 100 million inflators have been recalled by 19 major automakers around the world, and the resulting failure is often devastating. Units, especially those exposed to high levels of heat and humidity, can rupture ― causing an explosion that sprays metal fragments all over the cabin. There have been 18 known fatalities relating to the issue in the United States alone.

Most of those took place inside Honda vehicles, with the rest being split between Ford and BMW. While GM has been fatality-free, it's also come under increasing scrutiny for attempting to avoid recalls by petitioning the NHTSA on multiple occasions.

"Although we believe a recall of these vehicles is not warranted based on the factual and scientific record, NHTSA has directed that we replace the [ammonium nitrate] airbag inflators in the vehicles in question," GM said in a statement. "Based on data generated through independent scientific evaluation conducted over several years, we disagree with NHTSA's position. However, we will abide by NHTSA's decision and begin taking the necessary steps."

The recall covers GM full-size pickup trucks and SUVs, including the Chevrolet Silverado, Suburban, Tahoe, Avalanche, Cadillac Escalade, GMC Sierra, and Yukon. General Motors estimates it will cost around $1.2 billion, which will be over a quarter of its net income this year. Another 1 million vehicles will also need to be recalled globally, bringing the grand total up to 7 million units. GM has 30 days to provide the NHTSA with a proposed schedule for notifying vehicle owners ahead of the U.S. recall.
