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.

Chevy Volt sales surge with 2016 model, Nissan Leaf continues Autumn fall

The Nissan Leaf and Chevy Volt have been locked in sales combat since they arrived within a short distance of each other way back in 2010, and we continue to follow that fight closely. Though both vehicles approach driving efficiency from a different angle, they each have plugs and owners put a surprisingly similar number of electric miles on them. With the launch of its 2016 model, the Bowtie brand now appears to have the upper hand, clocking in a solidly improved performance for the month of October. According to GM's sales charts, the Chevy Volt made it into the loving embrace of 2,035 buyers last month. That's up a whopping 41 percent over the same period in 2014, and more than a 100 percent improvement from the 949-unit result in September. Now, we don't know how many of these were 2015 models and how many were the all-new 2016 edition. Dealers are, no doubt, incentivized to move the old inventory, and the latest and greatest is still only available in a limited number of states. Breaking out the sad trombones, Nissan recorded a mere 1,238 units moved in October. That's down 52.2 percent from the same month in 2014. That's also nine fewer examples than last month. Despite its recent sales travails, the Leaf still leads the calendar-year-to-date figures by a commanding 14,868 to 11,299 tally. We imagine the Japanese manufacturer is counting on an improvement in the situation once the 2016 model, with its larger, optional 30 kWh battery becomes available. You can compare these two stalwarts with the rest of the green-vehicle field in our By The Numbers post due out tomorrow. Green Chevrolet Nissan Electric Hybrid ev sales hybrid sales volt

Next Chevy Silverado could get this built-in tailgate step

General Motors just received patent approval for a tailgate step in a pickup bed. And given the timing, don't be surprised if you see this on the upcoming 2019 Silverado pickup (not the mention its GMC Sierra twin), expected to arrive in late 2018. According to the patent, granted in December of last year, the whole mechanism is housed in the tailgate assemble. The magic happens when a portion of the top half of the tailgate swings down and a step folds out. There's also a handle that locks into position to help climb up into the bed. As trucks get bigger and taller over the years, it gets harder and harder to access the cargo bed. Ford's solution with the 2009 F-150 was a step that slides out from the end of the tailgate. Back then, Chevy made an ill-advised ad highlighting the feature for Ford. And while Howie Long mocked the F-150's "man step" Ford saw almost a third of its trucks with the option in the first year. The GM design seems to improve on Ford's idea as it appears to be wider and has a back to the lower step. That is, you don't have to worry about stepping through the ladder-rung design as on the F-150. Ford's tailgate step later spread to the F Super Duty, and other cargo access assists have proliferated through the truck world. On the most recent redesign, the Chevrolet Silverado took a trick from the Avalanche and added cutouts to the corners of the rear bumper that act as a foothold. Ford also offers a deployable side step, Chevrolet has running boards that scoot rearward with a kick of the boot, and Ram offers fixed wheel-to-wheel side rails. Nissan is in on the game too, with an optional folding step that tucks under the rear bumper. We don't expect Chevrolet to comment on when or if we'll see this feature in the showrooms. But given that engineers are already hard at work on the next Silverado and the timing of this patent lines right up with the new truck's development cycle, we'll be disappointed if this patent stays in the file cabinet.
