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.

2016 Chevy Colorado grabs Motor Trend Truck of the Year award

It's not an easy feat to win Motor Trend Truck of the Year twice in a row, but the 2016 Chevrolet Colorado managed to do just that. Thanks to the introduction of the 2.8-liter Duramax four-cylinder diesel, the magazine decided to bring the pickup back to defend the title. In more good news for the Bowtie brand, the 2016 Camaro earned the magazine's Car of the Year award. The Colorado beat a tough group of finalists to earn the nod this year, including its GMC Canyon sibling. The Chevy Silverado and GMC Sierra also made this year's list. The Nissan Titan XD and latest Toyota Tacoma rounded out the challengers. A model had to shine in six criteria to earn the title: advancement in design, engineering excellence, safety, efficiency, value, and performance of intended function. Like it did with the Camaro, Motor Trend posted a story online that explained the rationale for picking the Colorado again. They praised the diesel profusely and lauded the whole platform as quite a capable hauler. This year's Motor Trend SUV of the Year honor went to the Volvo XC90. The Swedish 'ute had to win against an initial group of 16 candidates that the magazine eventually whittled down to finalists that consisted of the Honda Pilot, Lincoln MKX, the combined Mercedes-Benz GLE-Class and GLE Coupe, and Nissan Murano. "Seven-passenger people movers aren't supposed to drive like this," senior features editor Jonny Lieberman said about the Volvo in the announcement of the champions. The Honda CR-V won last year. In the explanation online, the judges applauded the XC90's new modular platform, and they loved both the T6 twin-charged engine and T8 hybrid version. The SUV's key enamored the writers, too.

GM executive chief EV engineer says reducing cost of plug-in vehicles is 'huge priority'

As we know, another major automaker investing heavily in electrified vehicles is General Motors, and it's doing things much differently than rivals BMW, Ford or Nissan. The Chevrolet Volt extended-range EV is a modest seller at its $35,000 sticker price but a huge hit with owners. The Chevy Spark BEV, still in limited availability, puts smiley faces on its owners and drivers. The just-introduced Cadillac ELR, a sharp-looking, fun-driving $76,000 luxocoupe take on the Volt's EREV mechanicals, has admittedly low sales expectations. With this interesting trio in showrooms and much more in the works, the third vehicle electrification leader I collared for an interview at Detroit's North American International Auto Show (see #1 and #2) was Pam Fletcher, GM's executive chief engineer, Electrified Vehicles. ABG: Why do your EREVs need four-cylinder power to extend their range when BMW's i3 makes do with an optional 650 cc two-banger? "We designed [the Volt and the ELR] to go anywhere, any time" - Pam Fletcher PF: I get that question all the time: why not something smaller? You don't really need that much. You use the electric to its ability, then you just need to limp. But we designed those cars to go anywhere, any time, and we don't want their performance to be compromised. If you're driving through the mountains, we don't want you to be crawling up grades, or to be limited on any terrain. So it's optimized to be able to travel literally the biggest grades and mountain roads around the globe at posted speeds. Because what if you can't? Another good reason: when the engine is on, you have to run it wide open throttle, max speed, most of the time. And while we can do a lot with acoustics, and the ELR has active noise cancelation, a small-displacement, low cylinder-count engine at high speed, high load all the time isn't something you want to live with. That's how we came up with the balance we did among the key factors of performance, NVH [noise, vibration and harshness] and range. ABG: Where you go from here? Is the range-extender engine due for an update? PF: We know and love the current Volt, and there is still a lot of acclaim about it, so we think it's a good recipe. But we are heavily in the midst of engineering the next-generation car, which I think everyone will love and be excited about.
