Saturn Ion steering probe closed by NHTSA

The National Highway Traffic Safety Administration has closed its investigation into faulty electric power steering motors affecting 334,728 Saturn Ions from 2004-2007, because General Motors has issued a recall for them. The group's research found that the part failed at a high rate in the vehicles.
GM recalled over 1.3 million vehicles a few weeks ago, including the Ion, because the power steering could suddenly fail. If broken, the cars could still turn, but it took greater effort. The automaker is also covering 96,324 2003 Ions with a lifetime warranty for their motors, but it's not immediately replacing them.
NHTSA opened its investigation into the motors in September 2011, and it found 4,787 complaints and 30,560 warranty claims that showed failure for the Ion alone. It estimated a complaint rate of 14.3 incidents per 1,000 vehicles and warranty claim rate of 9.1 percent. The investigation also found evidence of 12 crashes caused by loss of steering, two of which resulted in injuries.

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.

GM recalling another 2.7 million vehicles in five separate campaigns

The recalls keep rolling in from General Motors, evidently keen to avoid repeating the mistakes of the ignition-switch debacle and clean house. This time they're all coming at once, with five separate recalls announced together covering approximately 2.7 million vehicles.
The largest of the five actions involves over 2.4 million units of the previous-generation Chevrolet Malibu and Malibu Maxx, Pontiac G6 and Saturn Aura in order to fix brake light wiring harness, which have been found to be susceptible to corrosion. The recall is separate from the 56k Aura sedans which GM recently recalled over faulty shift cables, not to mention the previous massive recall of 1.3 million vehicles - some of them the same models - but appears to have resulted from the National Highway Traffic Safety Administration investigation that started with the G6 almost a year ago.
The second-largest campaign involves the 2014 Chevy Malibu, specifically those fitted with GM's 2.5-liter engine and stop/start system, approximately 140,000 examples of which has been found to have problematic brakes. The issue does not appear to be connected to the recall of 8k Malibu and Buick LaCrosse sedans (also involving brake woes) which we reported upon last week. Four crashes have been reported in such models, but GM admits it's not yet clear if the problem was a contributing factor in the accidents.
