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.

CNG-powered Chevy Sonic, Cruze headed your way

The value proposition for a Crazy Diamond Performance CNG ride was a little bit better before gas prices took a dive in the past month. Still, the Michigan-based company, which converts some of Chevrolet's compact vehicles to run on compressed natural gas, received approval late last month from the US Environmental Protection Agency (EPA) for two of its conversion models. And CNG is still pretty cheap. Crazy Diamond will start selling CNG versions of both the Chevrolet Cruze and Chevrolet Sonic. The startup will target fleet operators looking to cut both refueling costs and their carbon footprint. CNG can be found in much of the country in the low $2 range, while the average CO2 emissions are about 25 percent less than those of similar gas-powered vehicles. Average gas prices have tumbled by more than 30 cents a gallon in the last month, according to AAA, but they're still at close to $3. The two models will be able to go almost 300 miles on a full tank of CNG. Crazy Diamond said this summer that it would start selling converted a CNG-powered Cruze that delivers 130 horsepower for as low as $26,000. The turbocharged version goes for about $28,000. Take a look at Crazy Diamond Performance's celebratory press release below. Crazy Diamond Performance recieves EPA approval on its CNG Cruze and Sonic CDP receives EPA approval for its Mono-Fuel CNG Cruze and Sonic. Shelby Township, Michigan, October 30, 2014– Crazy Diamond Performance (CDP) receives EPA approval on its Mono-Fuel Compressed Natural Gas (CNG) Chevrolet Cruze and Chevrolet Sonic. Crazy Diamond Performance has received EPA approval on two new mono-fuel small passenger vehicles, the CNG Chevrolet Cruze and CNG Chevrolet Sonic. These new mono-fuel CNG platforms are the first of a series of small and fuel efficient vehicles coming from CDP, where cost, low emissions and reduced fuel consumption is important for not only fleet owners, but to the general public as well. "Soon to be available, are the 1.8L and 1.4L Cruze and Sonic CNG retrofit systems. These two vehicles represent a change in the status quo, with an OEM level integration of the fuel system and its components" states Michelle Fern, Executive Vice President CDP Inc. These vehicles provide flexibility for fleets looking to purchase a domestic small mono-fuel passenger sedan, but have not had an option until now. There are significant emissions benefits over its gasoline counterpart, with an average reduction in Carbon Dioxide (CO2) of 25%.
