(Reuters) - When General Motors Co Chief Executive Mary Barra faces Congress next week she will have to explain how the top brass at the biggest U.S. automaker can say they knew nothing for more than a decade about a faulty ignition switch linked to crashes and at least 12 deaths.
For lawmakers trying to find who to blame for the lack of responsiveness by GM and its regulator to the tragedies, and in particular the multi-year delay in recalling potentially dangerous vehicles off the roads, it may turn out to be a frustrating couple of days.
GM built a system to deliberately keep senior executives out of the recall process. Instead, two small groups of employees in the vast GM bureaucracy were tasked with making recall decisions, a system GM says was meant to bring objective decisions.
It means that lawmakers may also focus on asking who is responsible for a system that failed so badly that there weren't red flags raised for those higher up the food chain.
"In this day and age, to think that stuff like this can be kept quiet or forgotten is ridiculous," independent auto analyst and author Maryann Keller said. "The right question to ask is who knew, when did they know and why was this not brought forth to be dealt with. Did they hope that it was just going to go away?"
The company has recalled 1.6 million cars for a problem first noted in 2001, spurring the congressional enquiries as well as investigations by federal safety regulators, who will also testify, the Justice Department, and GM itself.
GM has said Barra and other top executives did not learn of the defective switches until January 31, explaining that smaller groups of lower-level company executives are responsible for leading a recall. Some executives who might use this argument include former CEO Rick Wagoner and his immediate successor Fritz Henderson, who have not discussed the matter publicly.
"The process here is supposed to be drilling deep into the data and objectively looking at this and having peer groups question it, and senior management and leadership's influence on that is not a healthy thing," global product development chief Mark Reuss said last week.
GM spokesman Jim Cain said the company was not yet commenting on why the decision to recall took as long as it did. GM is still investigating, he added.
Within the GM community, several former executives contacted by Reuters were asking why the ignition switch problem did not catch the attention of company attorneys, engineers and employees who worked with dealers and processed warranty claims.
"Why did these dots not get connected? Or worse, if they were connected, why did it take so long to do something?" said one former executive with experience in service matters, who asked not to be identified and had not heard of the issue while it was developing.
When the ignition switch in older-model cars, including the Chevrolet Cobalt and Saturn Ion, is jostled, a key could turn off the car's engine and disable airbags and other components, sometimes while traveling at high speed.
"Safety-related issues always got elevated attention," said a former GM engineering executive. "Something like engine stalls would get high priority."
Lawmakers will "ask questions that will hold people accountable for the terrible accidents that have occurred," Representative Henry Waxman of California, the senior Democrat on the House Energy and Commerce Committee, which is conducting that chamber's investigation of GM, told Reuters.
Barra will testify in the House on Tuesday and in the Senate on Wednesday.
Barra and the acting head of the National Highway Traffic Safety Administration, David Friedman, are likely to face a barrage of questions from skeptical lawmakers. They may also have to deal with accusations from victims' families, some of whom plan to attend the hearings.
A lawyer for some victims' families on Saturday invited Barra to meet with them in Washington next week.
"They need to hear from you, listen to your voice to know you are truly sorry and that you share in their grief and, to an extent at least, you understand their loss," Robert Hilliard wrote in a letter emailed to Barra and GM lawyers.
GM spokesman Greg Martin said by e-mail: "Mary has expressed GM's regret and deep sympathy for all of those affected by the recall. We are determined to earn our customers' trust and to take actions necessary to make our safety processes world class. Arranging a meeting in the media is not respectful to the families. We will respond directly to the invitation."
INSIDE GM'S RECALL PROCESS
For more than a decade the company carried out engineering and field evaluation inquiries to track the problem, according to a timeline that GM filed with regulators. That document and others also suggest a failure to share information within the company.
GM first learned of the issue in 2001 during pre-production of the Ion, and it issued so-called service bulletins to dealers with suggested remedies in 2005.
A February 2005 bulletin suggested dealers look for short drivers, who would be more likely to bump the steering wheel column, according to GM documents filed in a California lawsuit.
Meanwhile, in a GM document introduced last year in a Georgia lawsuit, 6-foot-3-inch GM engineer Onassis Matthews said he inadvertently turned the ignition key off with his knee while test driving a Saturn Ion in February 2004. Matthews suggested moving the ignition key to a different location.
As fatal accidents were reported, they were not always discussed broadly.
In March 2007, NHTSA officials told a group of GM employees of a fatal Cobalt crash in July 2005. GM's legal team had opened a file in 2005, two months after the crash, but the automaker's employees at the 2007 meeting with NHTSA were not aware of it.
In August 2011, an engineer was assigned to track a group of Cobalt and Pontiac G5 crashes in which the airbags did not deploy, but the process failed to include crashes involving Ion cars that resulted in deaths.
The issue was elevated to the two committees responsible for calling for recalls in 2013. GM declined to say if the committees had looked at the issue previously.
"Product recalls was a closely held activity," said a former executive in the global product development organization.
