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.

Mark Reuss: GM can't afford product 'misses,' has 'thought about' CT6 V-Series

Mark Reuss is a busy man. He oversees General Motors' global product portfolio, an all-encompassing task for a company that sold more than 9.9 million cars and trucks last year. When GM launches a well-received product, like the road-going rocket ship that is the Chevrolet Corvette Z06 – he gets credit. When the company stumbles with the slow-selling Chevy Malibu or grapples with fallout from the decade-old Saturn Ion and its flawed ignition switch, he gets blamed. GM owners, the press and sometimes the federal government, demand answers. Bob Lutz famously held the job before Reuss. So did Mary Barra, who's now GM's chief executive. There's a New GM, but the lineage is connected to a long history. When he's not thinking product, Reuss, an executive vice president, also runs the purchasing and supply chain for the company, which is still one of the largest industrial empires in the world. We caught up with Reuss on the floor of the New York Auto Show, where GM had just rolled out two crucial new products: the 2016 Cadillac CT6 and the 2016 Chevrolet Malibu. Speaking with a small group of reporters, Reuss delved into a variety of subjects, including the new Malibu, Cadillac's future (he thinks the ATS-V is going to "flame the M3 and M4"), and other topics. On fixing the Malibu: "We can't miss. We can't have those kinds of misses [like the previous generation] on our cars and crossovers and trucks. We can't do that. If we do that, we give a reason for someone to go buy something else. It's that simple. "On a car like the Malibu we have a chance to really fix all of that, which we have, and then lead. Then you've got a real opportunity there. So that's what we've really been focused on here – to fix those things." He later added: "We need that car here to transform Chevrolet desperately because it's the heart of the market. And when you think of Chevrolet, people will come back and think about what we did with the [new] Malibu and the Cruze... It's hugely important to us." On Cadillac: "If we go out and try and out-German the Germans, it's probably not going to work. We've got an opportunity here generationally where there's a lot of people younger than me that have parents that drove BMWs and Mercedes, and I think there's an opportunity there for those people to drive something different than what their parents did, and I think that's always been an opportunity in the auto industry if you look at the history of it.

Watch how Corvette Racing's new collision-avoidance radar system works

When it comes to technology used in racecars, we generally expect it to trickle down to production cars, not the other way around. Well, Pratt & Miller has developed a new rear-facing radar that operates in a similar fashion to what we're used to in modern blind spot detection systems, only it is also capable of tracking cars as they approach and relaying vital information to the driver via a large display screen.
The innovative radar system debuted at last weekend's 12 Hours of Sebring for Corvette Racing, and this system makes perfect sense for endurance races like this since the cars sometimes have to drive through the night and in poor weather conditions.
The radar can detect cars even with poor visibility, and uses easy-to-distinguish symbols for the driver to identify.
