US database may have overstated deaths in GM ignition switch recall

The FARS analysis didn't take into account fatal accidents where the airbags weren't supposed to deploy. Earlier today, we reported that the actual death toll attributable to GM's ignition switch problem had crested the 300 mark according to new research, well up from the original reports of 12 to 13 deaths. Now, word is breaking that the US government database that informed the study that the report was based on may have significantly overstated the correlation between the study and the GM recall. The initial study was conducted by Friedman Research on behalf of the Center for Auto Safety, and used something called the US Fatality Analysis Reporting System. To recap, the study claimed that over a 10-year period, 303 people were killed in Chevrolet Cobalt and Saturn Ion coupes and sedans when their airbags failed to deploy. These undeployed airbags were then linked to GM's ignition switch recall, which as we've explained before, can turn the ignition out of the "run" position and into the "off" or "accessory" position, disabling the airbags in the process. Now, according to a report from The Detroit News, which cites research from the Insurance Institute for Highway Safety and the National Study Center for Trauma and EMS at the University of Maryland, the FARS analysis didn't take into account fatal accidents in conditions where the airbags weren't supposed to deploy (which isn't to say crashes and deaths weren't caused by loss of control from the ignition switching off in the GM vehicles). According to the report, this was a significant number of the cases. There is another potential problem, too. According to that same report, the National Highway Traffic Safety Administration uses both FARS and another database on fatalities, called the National Automotive Sampling System/Crashworthiness Data System (NASS/CDS). Where FARS uses what the DetNews calls "not always reliable" police data to record vehicular deaths within 30 days of a crash, NASS/CDS relies on what's known as a probability sample. It collects data on 5,000 crashes each year – including some found in the FARS database – to calculate a probability figure. According to a 2009 IIHS study, "Among crashes common to both databases, NASS/CDS reported deployments for 45 percent of front occupant deaths for which FARS had coded nondeployments." In plain English, FARS doesn't provide a reliable count airbag deployments.

NHTSA could add 1M cars to GM recall

The Detroit Free Press is reporting that the National Highway Traffic Safety Administration may expand a recall campaign for faulty brake lamps. The agency is currently looking into complaints that certain 2004-2011 Chevrolet Malibu models as well as some 2007-2009 Saturn Aura sedans may have brake lights that do not illuminate when the driver presses the pedal. Alternatively, the lamps may also illuminate without input from the driver. General Motors recalled 8,000 Pontiac G6 models from the 2005 model year for the same problem, and NHTSA is currently investigating whether to add 550,000 more G6 models built between 2005 and 2009 to the list for the same issue.
In addition, investigators are currently examining 97 complaints from Malibu and Aura owners with the same trouble. If NHTSA adds those models to the recall campaign, more than one million units could be covered. GM, meanwhile, says there have been no accidents or injuries as a result of the problem.

GM calling in 56k Saturn Aura sedans over shift cables

General Motors may have made a few mistakes when it came to the whole ignition-switch debacle, and it will likely be dealing with the consequences for some time to come. But you have to hand it to Mary Barra and her team, because they're determined to clean house and avoid the same mistakes. That's why the biggest of the Big Three automakers in Detroit has been issuing recalls left, right and Renaissance Center. Aside from those vehicles fitted with the faulty ignition switches, GM has recalled over 50,000 Cadillac SRXs, another 50 heavy-duty pickups and some 51,000 full-size crossovers. There are bound to be more to come, and now it's issued another 50k-unit recall over faulty shift cables in the transmission.
The recall affects 2007 and 2008 Saturn Auras fitted with the four-speed automatic transmission manufactured between April 24, 2006, and October 31, 2007. The recall doesn't affect models equipped with the six-speed automatic, or for that matter any of the Aura's Epsilon platform-mates like the Chevy Malibu, Pontiac G6, Opel Signum and Vectra, Saab 9-3 or - carrying over from Fiat's aborted partnership with GM - the Fiat Croma, although many of those models used the same 4T40 transmission employed in the Aura.
In the affected vehicles, the shift cable might fracture while in motion, preventing the transmission from shifting into Park or the ignition from switching off, which the National Highway Traffic Safety Administration figures could lead to the car rolling away. Hence the recall of 56,214 units in the United States, owners of which can expect to hear from their dealership in due course to have the necessary components replaced.
