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.

Weekly Recap: Lincoln Continental serves up the style, Cadillac CT6 delivers the substance in New York

Lincoln and Cadillac grabbed the spotlight this week at the New York Auto Show in a dramatic fashion that evoked the brands' glory days. America's two luxury carmakers went toe-to-toe with their glittering reveals and plans for ambitious expansion. Both were selling their technology, style and the promise of a better future. Cadillac vs. Lincoln. At the Javits Center, 2015 seemed a lot like 1956. Neither company was interested in drawing comparisons with the other, which is fair, and accurate. They're in vastly different places in terms of sales and the pace of their turnarounds, but they hope to reach the same eventual destination at the pinnacle of the luxury-car world. Lincoln used the element of surprise to great effect with the Continental concept. A production version is still at least a year away, and the company was vague on details. Officially, we don't even know if it is front- or rear-wheel drive, though speculation abounds. Who cares? The seats can be adjusted 30 ways! The Continental also showed off a bold chrome grille that will be the new face of Lincoln. The blue bomber also rolled on blinged-out 21-inch polished aluminum wheels, used a 3.0-liter EcoBoost engine and had huge LED head lights with "laser-assisted" high beams. All of this resulted in almost blinding attention. The concept drew rave reviews, stirred controversy with Bentley designers who argued Lincoln ripped them off, and most importantly, pointed a way forward for the newly determined brand that hopes to compete with Mercedes, BMW, Audi, Cadillac and Lexus.

With production starting late this year, Cadillac had more specifics at the ready. Engines? Cadillac has a couple V6s and a turbo four for sure. It's working on a hybrid, and has considered a V-Series variant. It's based on a new rear-wheel-drive, aluminum-intensive chassis called Omega, features an advanced collision-mitigation system with automatic braking and has a cabin that's laden with "leathers, exotic woods and carbon fiber." It will be assembled at GM's Detroit-Hamtramck factory and goes on sale next year. At this point, Cadillac is more than willing to talk about every except for the price. The devil was not in the details for Cadillac, as evidenced by the CT6. But it wasn't for Lincoln either.

Stop-start standard in four-cylinder 2015 Chevrolet Impala

Chevrolet has announced that it will include stop-start technology as standard in the entry level 2015 Impala. The result is a nearly five-percent improvement in city fuel economy, also known as one mile per gallon, up to 25 mpg, combined. The 3.6-liter V-6 Impala will not feature stop-start. The 2015 Impala comes equipped with Chevrolet's 2.5-liter Ecotec four-cylinder engine, which will also offer 22 mpg in the city, and 31 on the highway. The 3.6-liter V-6 Impala will not feature stop-start and the mild-hybrid eAssist model from the 2014 MY, which got 29/25/35 combined/city/highway mpg, has been discontinued. Chevrolet spokesman Chad Lyons told Green Car Reports that not even one percent of the 2014 Impalas purchased were the Eco model. So Chevy is trying something different. With a seamless driving experience in mind, the new Impala's stop-start tech features software that governs under what conditions the feature will activate. The engine won't shut off if the car has not reached a speed of six miles per hour, so the start-stop won't be cycling during traffic jams. It can also fire the starter even if the engine has not come to a full stop, which quickens reaction time, particularly in instances of what Chevrolet calls "change-of-mind events." The stop-start function uses information about cabin temperature and humidity as well as battery charge to help determine whether or not to shut off the engine. The 2015 Impala has been engineered to reduce NVH, which will also help create a smoother stop-start experience for occupants, Chevy says. Motor mounts have been updated, and a burlier starter motor will help restart the engine after a stop. The Impala follows the 2014 Malibu as Chevrolet's second vehicle to feature stop-start tech. The four-cylinder model currently makes up over 30 percent of Impala sales. The 2015 Impala will be available beginning this summer, with a base MSRP of $27,735 (including destination charges). And while one MPG isn't a huge difference, neither is the price increase of just $50 for a bit of eco-minded innovation. Read on for more details in the press release below.
