GM announces 6 recalls covering nearly 720k cars

General Motors has announced yet another sprawling recall campaign, with six separate elements covering 717,950 vehicles on US roads. At this point in 2014, it's starting to seem like there are more days with a GM recall than without. Perhaps most troubling about this latest volley, though, is that every vehicle is from the past few years, indicating that GM's quality woes may not be limited to pre-bankruptcy vehicles.
The largest element of this latest campaign covers 414,333 units, and includes the 2011 to 2012 Chevrolet Camaro, 2010 to 2012 Chevy Equinox, GMC Terrain and Cadillac SRX and the 2011 to 2012 Buick Regal and LaCrosse. Only vehicles with powered, height-adjustable seats are covered. In these particular cars and crossovers, the bolt that secures the height adjuster actuator may loosen of its own accord and in some cases fall out completely. If this happens, the seats will be able to move both up and down. GM claims the vehicles are safe to drive, provided drivers don't vertically adjust their seats. This particular issue has caused one crash and three injuries.

2024 GMC Hummer EV SUV revealed, priced the same as the truck

Following up on the 2024 GMC Hummer EV pickup truck's big reveal back in October is the SUV variant. And it looks pretty much the way you would expect. From roughly the doors forward, it's the same as the blocky pickup. But the back half now has an enclosed cargo area, a full-door tailgate and full-size spare mounted to it. Besides the tweaked looks, the SUV is physically shorter. The full dimensions haven't been revealed yet, but the wheelbase is 8.9 inches shorter than the truck at 126.7 inches total. The overall length is likely reduced even further, since the tail is much shorter than the truck's with the rear wheels close to the bumper. Both of these changes will greatly improve breakover and departure angles, plus make the vehicle generally more maneuverable on and off road. GMC boasts that with four-wheel-steering, the turning circle is just 35.4 feet, about a foot and a half tighter than the truck. This content is hosted by a third party.

Higher EV3X and Edition 1 trims have three motors making 830 horsepower. Electric range varies between about 250 miles to 300 miles depending on specification. Extremely fast 800-volt, 300-kW DC fast charging is available and included on all but the base trim level. An Extreme Off-Road Package is available on EV2X and above that adds 18-inch wheels with 35-inch mud-terrain tires. You'll also be able to get the ground-clearance-increasing air suspension and four-wheel steering with the famous Crab Mode. Super Cruise will be standard on every GMC Hummer EV. Pricing and trim levels are nearly identical to the pickup truck, with only the Edition 1 varying. The base model starts at $79,995, and each trim and price is listed below. Prices are listed without the destination charge because that figure has not been revealed yet. EV2: $79,995 EV2X: $89,995 EV3X: $99,995 Edition 1: $105,595 ($110,595 with Extreme Off-Road Package) The Edition 1 SUVs will be available first with sales starting early next year.

Chevy's 6.6-liter Duramax is pretty much all new

To say there's a heated battle in heavy-duty pickups is an understatement, with Chevrolet, Ford, and Ram constantly trading blows of increased torque, horsepower, and towing capacity. The latest salvo is the revised, more powerful turbo diesel 6.6-liter Duramax V8 in the 2017 Chevy Silverado. It has 910 pound-feet of torque, an increase of 145, putting it nearly level with the Ford Super Duty. Here's a closer look at where those gains come from. How exactly did Chevrolet add all that torque plus 48 horsepower? The automaker essentially took a fine-tooth comb to the entire engine. Chevy says it changed 90 percent of the V8, and the cumulative effect of those small changes adds up to big increases. As you might guess, the turbocharger is updated. The larger unit features electric actuation of the variable nozzle turbine (VNT), and what Chevy calls a double axle cartridge mechanism that separates the VNT moving parts from the housing. That helps with heat performance as well, with a claim that the exhaust side of the turbo can run continuously up to 1,436 degrees Fahrenheit. Helping that cause are six exhaust gaskets made of Inconel - an nickel alloy that contains chromium and iron – and upgraded stainless steel for the exhaust manifold. Despite having the same cast iron cylinder block, albeit with some minor enhancements, the engine has new cylinder heads, pistons, piston pins, connecting rods, and crankshaft, which have all been upgraded to handle 20 percent higher cylinder pressures. Alongside the increase in pressure, Chevrolet also increased the cylinder head's structure with a honeycomb design. The pattern features high-strength aluminum with dual layer water jackets that not only improve strength, but also optimize water flow for better cooling. For 2017, the cylinder head also benefits from integrated plenum that aids the engine in getting more air under heavy loads. The cylinder head isn't the only component to get a minor update, as the pistons have a larger diameter pin for improved oil flow. The same detailed improvements has been bestowed to the humble connecting rods (second in our hearts only to the inanimate carbon rod). The new design has the bolts oriented roughly 45-degrees to the rod instead of parallel. The angle split design, as it's called allows for easier passage through the cylinder.
