GMs recall of 1.6 million vehicles, due to an ignition-switch problem linked to 12 fatalities, has put the Detroit automaker in Congress cross hairs, with potentially dramatic hearings kicking off in April.
GM chief executive Mary Barra is scheduled to testify on April 1 to a US House of Representatives panel investigating the ignition problem. In what could be a preview of such testimony, Barra on Monday declared in a video that something went wrong with our process and terrible things happened.
The handling of the defect by GM, which first noticed it in 2001, and federal regulators is the top priority of the powerful House Energy and Commerce Committee, according to aides.
Congressional investigations into consumer safety issues always have the potential of becoming a public relations nightmare for companies at the centre of the probes.
In early 2010, for example, Congress looked into sudden, unintended acceleration problems Toyota owners had been reporting for years, which were linked to five deaths.
The House Energy and Commerce Committee will have broad powers to investigate the actions of GM and the National Highway Traffic Safety Administration, including the ability to subpoena witnesses and documents. The panel has also invited NHTSA acting administrator David Friedman to testify at the April 1 hearing.
The session is the first in what will likely be a series of congressional hearings.
GM customers could have dramatic stories to tell, since the ignition issue turned off engines and disabled airbags in cars moving at high speed, resulting in deadly accidents.
One committee aide said nearly a dozen of the panels investigators were working on finding out why flawed ignitions in older Chevrolet Cobalts, Saturn Ions and other GM models were allowed to stay in the cars for so long with owners uninformed.
The broad question the committee wants to answer is, Is this a problem that could have been prevented or detected any earlier than it was said one House Energy and Commerce aide.
GM has long had allies in Congress, most notably Michigan representative John Dingell, the former committee chair. But the hearings will not be the first time the auto giant has been roughed up by lawmakers.
In 2012, a House of Representatives committee looked into an unrelated safety issue: Car battery fires in GMs new hybrid electric car, the Chevrolet Volt.
In 2008, GM, Ford Motor and Chrysler executives were taken to task by some members of Congress when they flew corporate jets from Detroit to Washington to testify in favour of a government bailout.
GMs allure may have suffered so much from its subsequent government takeover that only four members of Congress, out of 535, owned the company stock in 2012, according to the Center for Responsive Politics.
Five CEOs ran GM during the period of more than a decade since the ignition problem first appeared.
Some aides also warn that what might appear in hindsight to be inexcusable missteps by GM and federal regulators could have been complex and hard-to-define problems as they were unfolding.
The House hearings will be run by Michigan representative Fred Upton, a Midwesterner with an unassuming demeanour, who sometimes tells reporters, Just call me Fred.
Teaming up with Upton is the committees senior Democrat, representative Henry Waxman, a dogged legislator who has taken on the US tobacco industry, helped enact Obamas landmark healthcare law and won passage of a sweeping climate change bill in the House in 2009.
Also senior on the Energy and Commerce Committee is the dean of the House, representative John Dingell of Michigan, who was the panels top Democrat from 1981 to 2008 and is widely seen as GMs staunchest ally in Congress.
Joan Claybrook, a former National Highway Traffic Safety Administration head and president emeritus of the watchdog group Public Citizen, said that from time to time Congress had proven it can be tough on the US auto industry.
Claybrook and fellow consumer advocate Ralph Nader said in separate telephone interviews that the scope and aggressiveness of Congress investigation of GM would depend in part on sustained public outrage and pressure to act.
The public is mad as a hornet about this GM cover-up, she said.
Nader, who wants GM to set up a victims compensation fund, said the hearings would help keep the fire under the seat of the Justice Department as it pursues a criminal probe.
Republicans, who control the House, will not want to ally with GM on a safety problem that has enraged the public, added Nader, who won fame in the 1960s by taking on GM and championing safety issues in his book Unsafe at Any Speed.
If House lawmakers or senator Claire McCaskill, a Democrat who also plans to hold hearings in April in her Commerce Committee panel, decide legislation is needed, GMs lobbyists are sure to respond.
GM spent nearly $9 million last year on an army of lobbyists whose job is to promote the companys interests in Congress and throughout the federal government.
One registered lobbyist, Emily Porter, is a former adviser to House speaker John Boehner.
Asked about GMs sway with Congress, veteran Democratic representative John Larson of Connecticut told Reuters: It always makes it problematic for Congress because so many of the companys jobs are located in lawmakers home districts.
Still, House Energy and Commerce aides insist GM will get no favourable treatment. You have one hearing and you see where the evidence takes you before deciding next steps, said one aide.
