DETROIT (AP) — General Motors' safety crisis worsened on Monday when the automaker added 8.2 million vehicles to its ballooning list of cars recalled over faulty ignition switches.
The latest recalls involve mainly older midsize cars and bring GM's total this year to 29 million, surpassing the 22 million recalled by all automakers last year.
GM said the recalls are for "unintended ignition key rotation" and cover seven vehicles, including the Chevrolet Malibu from 1997 to 2005, the Pontiac Grand Prix from 2004 to 2008, and the 2003-2014 Cadillac CTS.
The company is aware of three deaths, eight injuries and seven crashes involving the vehicles, although it has no conclusive evidence that faulty switches caused the accidents.
CEO Mary Barra said the recalls stem from an extensive safety review within the company.
"If any other issues come to our attention, we will act appropriately and without hesitation," she said in a statement.
The announcement of more recalls extends a crisis for GM that began in February with small-car ignition switch problems. GM recalled 2.6 million older small cars worldwide because the switches can unexpectedly slip from "run" to "accessory," shutting off the engines. That disables power steering and power brakes and can cause people to lose control of their cars. It also stops the air bags from inflating in a crash. GM has been forced to admit that it knew of the problem more than 10 years, yet it failed to recall the cars until this year.
GM's conduct in the small-car recall already is under investigation by the Justice Department and both houses of Congress. Earlier this year, the company paid a $35 million fine to the National Highway Traffic Safety Administration for delays in reporting the small-car ignition switch problems.
The added ignition switch recalls raise questions about the safety of the switches in cars made by all manufacturers. On June 18, NHTSA opened two investigations of Chrysler minivans and SUVs as part of a widening inquiry into air bag and ignition switch problems across the U.S. auto industry.
NHTSA began asking automakers and parts suppliers for information on the interrelated issues after GM's small-car recall. NHTSA asked automakers and parts makers for information on switches and how long air bags will inflate after the keys are moved out of the "run" position to "accessory" or "off." In many cases, the answer is less than a second.
That led to the Chrysler inquiries, NHTSA said in a statement. "The agency examined all major manufacturers' air bag deployment strategies as they relate to switch position," the agency said in a statement. "NHTSA will continue to refine its knowledge of these systems."
GM's recalls on Monday bring this year's total so far to more than 40 million for the U.S. industry, far surpassing the old full-year record of 30.8 million from 2004.
