Some 2012-13 Chevy Volts may not have enough battery coolant

The 2012 and 2013 model year Chevrolet Volt extended-range plug-in vehicle may have a battery glitch caused by low coolant levels. No recall has been issued and General Motors is taking care of the issue at no cost to drivers. Some of the affected Volts may have lower-than-advisable coolant levels because of some pesky air pockets in the car's cooling circuit. When the coolant levels get too low, the charging system for the battery powering the car's onboard generator (i.e. the Rechargeable Energy Storage System, or the RESS) may be shut down, turning one's Volt into a run-of-the-mill gas-powered car, and a pricey one at that. The Car Connection says GM is advising owners of the '12 and '13 Volts to contact their local Chevy dealer for a free fix. GM representatives didn't immediately respond to a request for comment from AutoblogGreen for more details. We believe this is a separate issue than the one that brought 8,000 Volts back to the dealers for a battery coolant fix, what GM called a "voluntary customer satisfaction effort," a few years ago. General Motors sold 23,094 Chevy Volts last year after selling 23,461 Volts in 2012, so that fix-it list may get fairly lengthy. Check out a GM-Volt.com user thread related to this issue here. *UPDATE: Chevrolet spokesman Randy Fox confirmed in an e-mail to AutoblogGreen that the company issued a service bulletin to dealers that they may need to top off coolant levels on certain Volts because of the issue, and that the vehicle will "return to normal charging operation" once that's done.

Autoblog fan favorite car ads from Super Bowl XLIX

Super Bowl XLIX is in the books, and the New England Patriots emerged victorious. Of course, if you're like us, the big game wasn't so much about the battle between the east coast and west, so much as a fight between the world's automotive advertisers. We collected and collated all of last night's new ads and put them together for you to vote on. And yes, we're limiting this year's contest to last night's new features. That's why you aren't seeing Dodge's epic Wisdom among our collection of commercials, and it's a similar story with Chevrolet's Truck Guy Focus Group series, which highlights the new Colorado. You can still vote for your favorites. We won't be closing the voting on our Super Bowl page, so while the winners and losers are correct as of this writing, it's entirely possible that there could be some changes in the rankings as time goes on. So, without any further ado, here are the winning ads based on your voting. Nissan: With Dad Fiat: Ready For Action Jeep: Beautiful Lands BMW: Newfangled Idea Mercedes-Benz: Fable NASCAR: America Start Your Engines As for those ads that failed to impact you, loyal readers, Toyota was the absolute, undisputed loser. The Japanese brand ran four ads in total – two for Toyota and two for Lexus – and all of them have negative tallies as of this writing. Lexus' Make Some Noise and Lets Play and Toyota's One Bold Choice and My Bold Dad both had very weak showings among the commercials that aired, although they weren't alone. Neither Mazda nor Kia scored particularly well, despite featuring celebrity magic act Penn and Teller and former James Bond, Pierce Brosnan, respectively. Chevrolet was the winner of the losers, as of our writing, recording the fewest downvotes for its audience-punking The Big Game ad. If you want to take a second look at the losing ads, you can head back to our Super Bowl page for the complete collection. But for now, head into Comments and let us know what you think of the results.

Recharge Wrap-up: Batty battery covers, Mercedes at Silvretta, new Hyundai Sonata Hybrid available in 2015

Apparently, Chevrolet Volt battery covers make suitable homes for bats. As part of an Eagle Scout project, Matthew Netherland created 30 bat houses out of scrapped Volt battery covers donated by Chevy. 22 of the bat houses will be set up near hydroelectric dams in Michigan. Each bat house will accommodate 100 bats, and divert the scrapped materials from the landfill. The battery covers also make great nesting boxes for wood ducks, which General Motors has previously set up at its Milford, Michigan Proving Ground. Last weekend was the Silvretta E-Auto Rally, which saw emissions-free vehicles cross the Montafon Mountains in Austria, including cars from Mercedes-Benz. These cars included the B-Class Electric Drive, B-Class F-Cell, SLS AMG Electric Drive and even the Smart Fortwo Electric Drive. Also on hand for the Silvretta Classic Rally was a V8-powered C111, a 1978 Mercedes-Benz 450 SLC and 300 SL Roadster. Read more in the press release, below. BMW has finalized pricing for the i8 in the US at $135,700 (plus $925 in destination charges). In addition to the base price tag, which we've known for a while, BMW Blog has the complete pricing guide with options and packages. Most of the i8 orders were the Pure Impulse World package, which includes various aesthetic upgrades. It also provides membership to the BMW i Pure Impulse Program, which allows you to "to enjoy innovative ideas and trends in a variety of areas, including home styling, culture, gourmet gastronomy, design and many more." Head over to BMW Blog for more information. The new generation of the Hyundai Sonata Hybrid will arrive later than the rest of the model lineup, confirms Car and Driver. While the gas-powered Sonatas get updated now for the 2015 model year, the Hybrid remains unchanged until late this year or early 2015, when it will arrive as a 2016 model. Hyundai is offering a 2015 Sonata Eco edition, but with 28 miles per gallon in the city and 38 mpg highway (32 combined), it's not quite as appealing as the current Sonata Hybrid's 36/40/38 figures. Read more here. In June, average US fuel economy was 25.5 miles per gallon, making it the fifth straight month above 25 mpg, according to University of Michigan. The average window sticker ratings from vehicles sold in June dropped slightly from 25.6 mpg in May. The year started at 24.9 mpg in January, and hasn't dropped below 25 mpg since.
