Engine block heater issues force GM to recall 324,226 diesel heavy duty trucks

General Motors has issued a recall on 324,226 diesel heavy duty trucks that could be susceptible to short circuits, and consequently, potential fire. The recall affects several models of heavy duty Chevrolet Silverados and GMC Sierras with optional engine block heaters. GM is recalling seven different truck models spread across three years. The recall affects the 2017-2019 Chevrolet Silverado 2500HD, 2017-2019 Silverado 3500HD, 2019 Silverado 4500HD, 2019 Silverado 5500HD, and 2019 Silverado 6500HD, plus the 2017-2019 GMC Sierra 2500HD and 2017-2019 Sierra 3500HD. Specifically, it includes these models with the 6.6-liter Duramax diesel engines and the optional engine block heater. The recall technically deals not with the engine block heater itself, but the way it is connected. According to NHTSA campaign No. 19V328000, the engine block heater cord or the terminals that link the cord to the heater could short circuit. A short circuit could potentially damage engine components and result in a fire. According to The Detroit News, 19 fires have been reported but nobody has been injured. GM has yet to figure out a fix, and thus has not yet released a notification schedule for affected customers. If you believe your vehicle is part of the recall, contact GM customer service at 1-586-596-1733 and use reference number N182206310.

2016 Chevrolet Volt First Drive

There's a hit vehicle hiding in GM's formula for the Chevy Volt. You can sense it in the enthusiasm that current Volt drivers have for their cars. You can see it in the amount of money GM has poured into its extended-range electric vehicle project. And perhaps most importantly, you can feel it from the driver's seat of the new, second-gen model. The big question is whether or not GM will be able to turn its much-hyped 'halo car' into a best-seller this time around. After driving it in northern California, I can tell you that the Volt is tremendous. But we all know it takes more than that to create a hit. GM has so far sold over 82,000 Volts in the US. That's respectable, but in the early, glory days before the car launched, company representatives were talking about much more impressive numbers. With a few years to talk to customers and potential prospects, GM has learned a lot about what makes someone buy a Volt. For the 2016 model, Chevy has changed just about everything for the better. The new Volt has more all-electric range (53 miles vs. 38 in the first generation), is more fuel efficient whether you're looking at the overall value (106 combined MPGe vs. 98) or just when the car burns gas (42 miles per gallon vs. 37). All of that means that the car's overall range is bumped up to 420 miles, from 380. The battery is smaller and lighter while offering more energy capacity. The range-extending gas engine is bigger (1.5 liters vs. 1.4) but it's also more efficient and can burn regular gasoline instead of just premium. The Volt's overall range is bumped up to 420 miles, from 380. The cost is lower, too: $33,995 vs. $34,170, before incentives. This is a car that GM thinks will compete against the Toyota Priuses and Nissan Leafs of the world (as its new ads make abundantly clear). All three cars have completely different powertrains, but we all know that they're the headline green cars of our time (along with Tesla), so buyers will have to want to pony up a bit more money if they like what the Volt is offering. The 2016 Leaf with its 107-mile range starts at $37,640 (before incentives), while a 2015 Prius can be had for $25,035 (pricing for the 2016 has not yet been announced). So, on paper, the new Volt is an all-around winner. I'm here to tell you that it wins on the road, too. You can't help but notice the changes. They are literally front and center.

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.
