New Takata problem results in recall of 414 GM vehicles

An airbag-inflator rupture discovered by Takata during testing has resulted in a new recall affecting 414 vehicles from General Motors, including 395 of them in the US. This latest campaign covers 2015 model-year examples of the Buick LaCrosse, Cadillac XTS, Chevrolet Camaro, Equinox, Malibu, and GMC Terrain. There are no reported breaks in any of these vehicles on the road, and the company estimates only one percent of them actually have the faulty parts. According to documents submitted to the National Highway Traffic Safety Administration (as a PDF), one side-airbag inflator failed a cold test at -40 Fahrenheit "releasing high pressure gas and propelling the separated components apart." The supplier told GM about the failure the next day. In these vehicles, the safety device might not only burst but the bag could inflate incorrectly, as well. GM and Takata say that a cause is not yet known, but they are "conducting an investigation." GM will begin notifying affected owners via overnight mail on Oct. 19. Dealers will replace the side airbag modules on all of the affected vehicles with new components outside of the suspect lot. All of the removed parts will also be collected for further study. Takata's faulty front airbag inflators have resulted in a serious scandal for the supplier. Initial figures indicated 34 million US vehicles are need of repair, though more recent figures have knocked that down to 23.4 million bad parts in 19.2 million automobiles. GM was already among the dozen automakers with models to fix, and some of its pickups were affected, along with the Saab 9-2X and Pontiac Vibe. GM Statement: General Motors is recalling 395 cars and crossovers in the U.S. because one of the front seat side air bags inflators may be defective. In the event of a deployment, the air bag's inflator may rupture and the air bag may not properly inflate. The rupture could cause metal fragments to strike the vehicle occupants, potentially resulting in serious injury or death. GM is unaware of any incidents involving vehicles with these components, which were part of a lot in which one inflator failed acceptance testing at the supplier. Dealers will replace the side air bag module or modules in affected vehicles. Including Canada, Mexico and exports, the total population of the recall is 414, GM estimates 1 percent of the recalled vehicles may have the defect.

Why does the Corvette Stingray have so many vents? Here's why

Just looking at the new 2014 Chevrolet Corvette Stingray, it's not hard to see that the car's design was created with aerodynamics at the forefront, but Chevrolet designers point out exactly what went into designing the iconic coupe in a pair of recently released videos. The videos show the Corvette going through early design phases, including clay models and wind tunnel tests, as well as talking to the car's chief engineer, Tadge Juechter.
Both videos help explain various aspects of the C7 Corvette, but it's the aero tuning of the car that is most interesting. This includes extra attention paid to the lower air dam and vented hood to help reduce drag and lift, while the rear quarter inlets are for differential and transmission cooling. Juechter said that some of these aero-tuned elements were inspired from GM's involvement in racing.
If you have about five minutes and you can't get enough information about the new 'Vette, then check out the videos posted below.

Chevy Volt replacement battery cost varies wildly, up to $34,000

There's a growing hubbub in the plug-in vehicle community over what looks like some ridiculously cheap replacement batteries for the Chevrolet Volt going up for sale. GM Parts Online, for example, is selling a replacement Volt battery with an MSRP of $2,994.64 but, with an online discount, the price comes down to $2,305.88. For the 16-kWh pack in the 2012 Volt, that comes to a very low $144.11 per kilowatt hour (kWH). But is it a real deal? How can it be, when a Chevy dealer may quote you a price of up to $34,000 to replace the pack? For a 16-kWh Volt pack, $2,305.88 comes to a very low $144.11 per kWh. But is it a real deal? Battery packs in alternative propulsion vehicles are usually priced by the kWh and, historically, they've been thought to be in the range of $500-per-kWh for OEM offerings. Since automakers are understandably secretive about their costs, we still don't know what the real number is today, but we do know it varies by automaker. Tesla, for example, has said it pays less than $200-per-kWH at the cell level but, of course, a constructed pack would be more. Whatever is going on, li-ion battery prices are trending downward. So, $144.11 certainly sounds great, but what's the story here? Kevin Kelly, manager of electrification technology communications for General Motors, reminded AutoblogGreen that GM Parts Online is not the official GM parts website and that, "the costs indicated on the site are not what we would charge our dealers or owners for a replacement battery. There would be no cost to the Volt owner if their battery needs replacement or repair while the battery is under the eight year/100,000 mile limited warranty coverage provided by Chevrolet." A single price tag also can't be accurate for everyone, Kelly said. "If the customer needs to have their battery repaired beyond the warranty, the cost to them would vary depending on what needs to be replaced or repaired (i.e. number of modules, which specific internal components need replacement, etc.)." he said. "So, it's hard for us to tell you exactly what the cost would be to the customer because it varies depending on what might need to be repaired/replaced. As a result, the core charge would vary." But, is the $2,300 price even accurate for anyone? Thanks to a reader comment, we see that this similar item on New GM Parts makes it look like the lithium-ion modules that Kelly mentioned – where a lot of the expensive bits are – are not included.
