General Motors released their updated chronology to the recall effecting the 2007 and earlier Chevrolet Cobalt and HHR; Pontiac G5 and Solstice; and Saturn Ion and Sky. Most of the new chronology works just to update the document with the expanded recall, but there’s a key update:
During the Saturn Ion development in 2001, a preproduction model had an ignition cylinder problem that was caused by, you guessed it, “low detent plunger force,” the result being that it takes a low amount of effort to knock the key out of the “run” position.
The 2001 Saturn Ion pre-production report goes on to say that design changes to the ignition cylinder seemingly eliminated the issue. However, in 2003 a report documented an instance where an Ion was brought in for repair, and the technician servicing the car experienced a situation where the Ion stalled while driving, due to the key rotating “off.” The technician noted that “[t]he owner had several keys on the key ring,” and initially thought that “[t]he additional weight of the keys had worn out the ignition switch.” The technician replaced the ignition cylinder, and the report was closed.
As we discussed in previous posts, Technical Service Bulletins (known by GM as Information Service Bulletins, or ISP for short) is the result of several field reports on a common issue, and is eventually entered into a database known as the General Motors Vehicle Information System, or GMVIS for short. ISB’s are not found by a tech unless they are searching for a related issue. Thus, the 2003 example above is an early report that lead to ISB #05-02-35-007.
Also outlined in the updated chronology deals with Saturn’s sensing and diagnostic module (“SDM”), which differs from the Cobalt in that it is designed to stop recording once the engine of the car is no longer running. This means that crash data from a Saturn Ion SDM is not as conclusive as a Cobalt’s, which continues to record the ignition position during an accident in which the engine has been turned off.
Despite this, GM believes that the ignition cylinder issue has lead to eight accidents and four fatalities involving a Saturn Ion. At least three accidents involving the Chevrolet HHR can be linked; but no accidents involving a Pontiac Solstice or Saturn Sky have been found by GM. This brings the confirmed number of accidents to 31, and total number of deaths to 13.
The New York Times reports that in a study initiated by the Center for Automotive Safety (“CSA”), a private watchdog group, Friedman Research Corporation analyzed federal crash data and found 303 deaths linked to no airbag deployment in the recall-effected vehicles. The study does not link these no-airbag crashes to the ignition switch maladies, but questions why the NHTSA took so long to react to a mounting problem with the Cobalt and Ion.
In the letter to the NHTSA, CSA states the “NHTSA should have and could have initiated a defect investigation to determine why airbags are not deploying in Cobalts and Ions in increasing numbers.” And GM has began its own internal investigation, hiring former United States attorney for Northern Illinois, Anton Valukas to investigate.
“Research is underway at G.M. and the investigation of the ignition switch recall and the impact of the defective switch is ongoing,” Mr. Martin, the G.M. spokesman, said. “While this is happening, we are doing what we can now to ensure our customers’ safety and peace of mind. We want our customers to know that today’s G.M. is committed to fixing this problem in a manner that earns their trust.”
What have we learned through all of this? The engineers and technicians did their job, and GM had every piece of the puzzle; but as explained in the chronology, each piece was scattered about by an alphabet soup of committees. The review process let us down, both with Delphi’s quality control in the early switches and GM’s internal reaction to the situation. Further investigation will hopefully lead us to fully understanding the error in GM’s review process.
