GM may recall another 4.3M vehicles for Takata airbags; cost could reach $550 million

GM said in May it would recall 1.9 million vehicles for Takata Corp. airbag inflators that may not work properly. In June it expanded that recall to another 600,000 vehicles after a review of ownership data.

GM said in a securities filing that the costs of replacing Takata airbag inflators in the 4.3 million additional vehicles would be $550 million, while replacing inflators in the 2.5 million vehicles recalled to date would cost as much as $320 million.

GM said it does not believe there is a safety defect in any of the 6.8 million vehicles, but agreed to the initial recall after talks with the U.S. National Highway Traffic Safety Administration.

In May, the NHTSA said 17 automakers will be required to recall another 35 million to 40 million U.S. airbag inflators assembled by Takata. Previously, 14 automakers had recalled 24 million vehicles with 28.8 million inflators linked to at least 13 deaths and more than 100 injuries.

GM said it believes that "the results of further testing and analysis will demonstrate that the vehicles do not present an unreasonable risk to safety and that no repair will ultimately be required."

GM has not begun making repairs on the initial 2.5 million vehicles recalled, and has not yet accounted for the costs of the recall.

GM said its Takata inflators have a unique design that does not pose a safety risk.

The company said data showed no cases of an airbag rupturing among 44,000 deployments in large GM pickups and SUVs that contain Takata inflators. Takata inflators used in GM trucks and large SUVs are designed with different venting for hot gases released when the airbag deploys, and they are installed in the vehicle in a way that minimizes exposure to moisture, GM said.

GM's stance is at odds with the position of regulators that all frontal Takata airbag inflators without a drying agent must be recalled.

Unsafe over time

NHTSA spokesman Bryan Thomas on Thursday reiterated the agency's position. "The science clearly shows that these inflators become unsafe over time, faster when exposed to humidity and variations of temperature," he said.

NHTSA on Thursday also posted guidance on how automakers can petition for permission to alter the recall schedule. NHTSA said the process should not be "used to eliminate a population of vehicles from the recall."

Upward of 100 million vehicles worldwide with Takata airbag inflators have been declared defective and are linked to 13 deaths and more than 100 injuries. Inflators can explode with too much force and spray metal shrapnel into vehicle passenger compartments.

Another recall

Separately, GM said it plans to recall 307,000 older Chevrolet Impala cars worldwide because the airbags may not deploy in the event of the crash.

The largest U.S. automaker said the front passenger seat frame in 2009 and 2010 model Impala cars might rub against and damage electrical wires, which could cause the airbag fuse to short. Dealers will add anti-abrasion tape to prevent damage.

GM said it had reports of two crashes and two injuries linked to the defect. The recall includes nearly 290,000 vehicles in the U.S. and about 17,000 in Canada.

GM did not immediately disclose the airbag manufacturer for this recall.
