GM recalling 118K Colorado, Canyon pickups over missing hood latches

General Motors has announced a recall of 118,800 Chevrolet Colorado and GMC Canyon pickup trucks due to the possibility of secondary hood latches not being installed at the time of manufacture. The affected vehicles are from the 2010, 2011 and 2012 model years, all of which were built between November 9, 2009 and August 28, 2012.
According to the official National Highway Traffic Safety Administration report, these trucks fail to "comply with the requirements of Federal Motor Vehicle Safety Standard No. 113, 'Hood Latch System.' The hood may be missing the secondary hood latch." In other words, owners of these trucks could find their vehicles' hoods opening unexpectedly while driving.
The official recall campaign is expected to begin on January 17, 2013. Dealers will inspect the affected pickups and if a secondary hood latch is not present, one will be installed free of charge. Scroll down to read the official NHTSA report.

What the electric Hummer's size and weight means for its efficiency

The 2022 GMC Hummer EV Edition 1. Tim Levin/Insider If you think driving a pint-sized Nissan Leaf is as good for the planet as driving a huge electric Hummer, think again.  The GMC Hummer EV uses significantly more electricity than other EVs, meaning it produces more pollution upstream.  The electric Hummer weighs 9,000 pounds and its battery weighs as much as a Honda Civic. The new electric Hummer rolls through town without a deafening engine rumble or a cloud of toxic fumes, but it doesn't exactly tread lightly.  The colossal truck weighs an astonishing 9,000 pounds. (Think two Toyota Tacomas, three Honda Civics, or 24 Shaquille O'Neals.) Moreover, the GMC Hummer EV is in many ways a supersized gas guzzler for a new era. It repackages many of the same flaws of hulking SUVs and trucks of years past — and proves not all zero-emission cars are created equal. EVs can be energy guzzlers too On the whole, electric cars use less energy than gas-powered ones. But they aren't all equally efficient.  No surprise here: The Hummer needs more electricity than any other EV on the market to move its elephantine frame. The Environmental Protection Agency rates the pickup at 47 MPGe (miles per gallon of gasoline-equivalent). For comparison, the Tesla Model 3 sedan is nearly three times as efficient, earning a rating of 132 MPGe. The Ford F-150 Lightning, another electric truck, gets 70 MPGe.  This has real consequences: Since the US gets 61% of its energy from oil, coal, and natural gas, the more electricity a car needs, the more pollution it creates upstream.  As the Union of Concerned Scientists put it: "Both EV cars and trucks are much cleaner than their gasoline counterparts, but electric trucks are responsible for more global warming emissions than electric cars simply because trucks are larger and heavier."  The 2022 GMC Hummer EV Edition 1. Tim Levin/Insider The Hummer EV is also resource-intensive to manufacture, requiring a ginormous (and weighty) battery to give people the 300-plus miles of range they desire. You could produce three Chevrolet Bolts with the same battery cells consumed by one Hummer.

2019 GMC Sierra Denali MultiPro tailgate and CarbonPro bed explained

When the 2019 Chevy Silverado debuted at the Detroit Auto Show in January, GM's Mark Reuss promised that the new 2019 GMC Sierra would have some significantly different styling and features than its corporate sibling. Previously, the Sierra has been little more than a Silverado with new front and rear fascias and some extra chrome inside and out. Well, Reuss was right. In addition to new sheetmetal, the Sierra exclusively gets the slick MultiPro tailgate and CarbonPro carbon-fiber bed box The tailgate really is trick. At the debut, GMC had multiple demonstrations, with engineers walking us through all six different configurations. Like all Sierra tailgates, the MultiPro version uses an aluminum skin to reduce weight. It's easy to tell which tailgate is which, as the MultiPro has a distinct cutout in the middle where it can fold down or extend. It can be used to extend the bed, drop to allow easier access, provide a sort of workbench, or be used as a step to help get into the bed. Yes, there's even a handle. Ford who? The step itself can support up to 375 pounds, 75 pounds more than Ford's similar tailgate step. This tailgate really is unique to the Sierra and is standard on SLT and Denali models. That said, the power-operated tailgate from the Silverado won't be coming to the GMC. Chevy gets its own exclusive, too. The Sierra's other big exclusive is the carbon-fiber reinforced plastic bed box. CFRP replaces steel inside the bed though not on the fenders. The bed uses four pieces; one for the bottom, one in the back and two along the sides. This isn't a CFRP. There is no steel hiding underneath these panels. Just take a peek underneath. The bed is a composite that uses 1-inch carbon-fiber threads, not a weave. Sheets of CFRP are molded and quenched — a process where the plastic coagulates and solidifies, locking in the carbon fiber — in just 60 seconds. That allows GMC's supplier to crank out these much more quickly. The finish looks like black fiberglass, though an engineer said that this wasn't the final production version. The final model will have different textures in order to improve grip and keep things from sliding around. GMC is touting the material's dent and corrosion resistance, though it remains to be seen how well it holds up to cracking. A video at the reveal showed people going after it with hammers and cinder blocks, but in-person demonstrations weren't available.
