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. A further 112k Corvette models from the 2005-2007 model years are being called in for problems with their low-beam headlamps resulting from a flexing relay control circuit wire that's not meant to bend. GM says it is "aware of several hundred complaints" about this issue, but notes that there have been no reports of related accidents. In addition, over 19k examples of Cadillac CTS from the 2013 and 2014 model years are being recalled over windshield wipers that might not work after a jump start. Finally, GM is also bringing in 477 examples of its 2014 Chevy Silverado, Tahoe and GMC Sierra (though not the Yukon) to fix a problem with a tie rod in its steering rack. As ever, all recall repairs will be performed free of charge, and GM is now estimating that recall-related actions this quarter will result in an estimated $200-million charge against its second-quarter earnings.

See all seven colors available on 2016 Chevy Volt

General Motors has been happy to promote the 2016 Chevy Volt in the shiny blue color. On the company's website for the car, though, we can find all seven exterior colors, thanks to the magic of digital technology. We went through the site and played around with the option picker and put together a gallery of all the colors the new Volt will be available in as well as the five interior options. For the record, the exterior colors are: Kinetic Blue Metallic, Iridescent Pearl Tricoat, Summit White, Silver Ice Metallic, Mosaic Black Metallic, Siren Red Tintcoat, Heather Grey Metallic. You'll be forgiven if you can't quite tell the difference between the Pearl and the White in these images, but both colors have been available on the 2015 model year Volt. GM spokesperson Michelle Malcho told AutoblogGreen that buyers do have a preference, with Pearl accounting for 10 percent of the sales and Summit White accounted for 17 percent. The Pearl color is a tri-coat and thus has a $995 price premium, which was likely a factor as well. The interior of the new Volt will have two cloth options (Dark Ash and Jet Black) and three leather choices (Dark Ash, Jet Black, and Jet Black/Brandy). That last one will only be available in the LTZ trim level. You can play around with the color adjuster yourself here. Kathy Sirvio, the color and design manager of the Volt design team, told AutoblogGreen that, "Kinetic Blue is a marketing name. At Design we call it 'Blew Me Away'. That is it in a nutshell. The blue color is vibrant, rich and eye catching. It may not sell at the highest volume, as we know from history whites, blacks and silvers are the dominant color sales. However, it will tell everyone who sees it on the street that here comes a new vehicle and it is expressive in all the right ways." The next-gen Volt arrives later this year with a starting price of $33,995. The powertrain upgrades will push the all-electric range to 50 miles and the gas-only fuel economy to 41 miles per gallon.

This map reveals the cleanest vehicles based on location

Naysayers love to point out how dirty the electricity grid mix is when it comes to charging electric vehicles. Curmudgeons are eager to jump into any conversation about EVs to enlighten the lucky listeners about how plug-in cars contribute to pollution, sometimes even throwing in a dash of climate-change denial for good measure. (Thanks, buddy. Pray, tell me more about the plight of oppressed SUV owners.) Unless someone buys an EV just because they think they're cool (which, yeah, they often are), they probably have at least a passable understanding of their environmental pros and cons. As many EV owners are already aware, location has a lot to do with any particular plug-in car's carbon footprint. Still, there's always more to know, and knowledge is not a bad thing, especially if one uses it to do the right thing. That's why this handy-dandy map from Carnegie Mellon University is so interesting. CMU researchers have compiled information about the lifecycle greenhouse gas emissions of various EVs based on where they're charged, as compared to gasoline-powered vehicles. The researchers looked at the Nissan Leaf, Chevrolet Volt, and Prius Plug-In Hybrid versus the gasoline-dependent Toyota Prius hybrid and the stop-start-equipped Mazda3 with i-ELOOP and compared grams of CO2 emitted per mile. CMU takes into account the grid mix, ambient temperature, and driving patterns. CMU takes into account the grid mix based on county, as well as ambient temperature and driving patterns in terms of miles traveled on the highway or in the city. For instance, if you drive a Nissan Leaf in urban areas of California, Texas, or Florida, your carbon footprint is lower than it would be if you were driving a standard Toyota Prius. However, if you charge your Leaf in the Midwest or the South, for the most part, you've got a larger carbon footprint than the Prius. If you live in the rural Midwest, you'd probably even be better off driving a Mazda3. Throughout the country, the Chevrolet Volt has a larger carbon footprint than the Toyota Prius, but a smaller one than the Mazda3 in a lot of urban counties in the US. The Prius and Prius Plug-In are relatively equal across the US. Having trouble keeping it straight? That's not surprising. The comparisons between plug-in and gasoline vehicles are much more nuanced than the loudest voices usually let on.
