2015 Sierra All Terrain HD looks ready to hit heavy-duty trails

GMC is getting its heavy-duty trucks ready for the mud this summer with its All Terrain package for the Sierra 2500HD and 3500HD. Meant to blend style, tech and ruggedness, the pack includes a lot of extra chrome outside and an off-road package underneath.
The 2015 Sierra All Terrain HD trucks naturally come standard with four-wheel drive with an electronically controlled transfer case to handle things in the dirt. The Z71 off-road package is also standard, which includes Rancho twin-tube shocks, hill descent control and a skid plate. To add some style when off the beaten path, the pack includes chrome trim on the mirror caps, lower bumper and grille surround, plus LEDs around the headlights and 18-inch wheels (20-inchers are optional on the 2500HD). The 3500HD also gets chrome, adjustable outside camper mirrors. The interior receives a technology upgrade thanks to the standard rearview camera and IntelliLink infotainment that can act as a Wi-Fi hotspot through OnStar 4G LTE, read text messages and includes Siri Eyes Free for iPhone users.
The All Terrain package goes on sale on both trucks this summer and is offered on either the SLE or SLT trim levels in double cab and crew cab models. The standard engine is the 6.0-liter V8 with 360 horsepower and 380 pound-feet of torque, but the Duramax 6.6-liter, diesel V8 with 397 hp and 765 lb-ft is also available. The gas engine is mated to a Hydra-matic six-speed automatic, and the diesel uses an Allison six-speed automatic. Scroll down to read the full announcement about these heavy-duty off-roaders.

GM recalls 3.8 million vehicles in North America due to braking issue

WASHINGTON — General Motors Co said Wednesday it was recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and that has been linked to 113 accidents and 13 injuries. The recall covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles. In late June, GM recalled 310,000 vehicles in Canada for the same issue. GM did not immediately explain why the Canadian recall occurred more than two months before it called back the vehicles in the United States. The recall was triggered because the amount of vacuum created by the vacuum pump may decrease over time, GM told the National Highway Traffic Safety Administration (NHTSA) in documents posted on Wednesday. The NHTSA opened a preliminary investigation into the issue last November, and said it had reports of nine related crashes and two injuries. It provided GM in July with additional field reports that prompted the automaker to open an investigation. GM said it could affect braking in "rare circumstances." The NHTSA said in a statement the "vehicles may experience brake boost failure, which would require increased brake pedal effort, leading to a hard brake pedal feel, and potentially increased stopping distance." GM said dealers will reprogram the electronic brake control module to improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. GM said the vacuum assist pump, which is lubricated with engine oil that flows into the pump through a filter screen, can in some cases lose effectiveness over time, as debris such as oil sludge can accumulate on the filter screen. GM told NHTSA that prior model years used a different brake assist system design, and vehicles manufactured after 2018 were not equipped with the affected pump design. Separately, GM said on Wednesday it is recalling 270,000 additional U.S. vehicles in three smaller recalls, including 177,000 2018 Chevrolet Malibu cars with 1.5L turbo engines because an error in the engine control module software may result in the fuel injectors being disabled.

2019 GMC Sierra AT4 gives Raptor and Ram a new off-road rival

The 2019 GMC Sierra AT4 blends off-road hardware into a modern, thoroughly updated pickup truck that doesn't skimp on power, luxury, or safety equipment. From its higher suspension setup to its available carbon-fiber cargo bed and the new MultiPro tailgate, the 2019 Sierra AT4 is a direct shot across the bow — or cargo beds, if you prefer — of staunch rivals like the Ford F-150, Dodge Ram and Toyota Tundra. Revealed tonight in New York City, ahead of this week's New York International Auto Show, the truck may seem to be in a strange setting. Then again, with the amount of tire-swallowing potholes currently scattered around the Big Apple, a rugged truck like the Sierra AT4 could be the perfect vehicle for either off-road excursions or an especially bumpy commute. Riding two inches higher than the standard 2019 Sierra, the AT4 comes with standard features like all-wheel-drive with a two-speed transfer case, locking rear differential, Rancho monotube shock absorbers designed specifically for off-roading, along with skid plates and 18- or 20-inch alloy wheels fitted with all-terrain tires or optional, mud-loving Goodyear Wrangler Duratecs. Hill descent control and GMC's Traction Select system are also standard. The latter of these two lets the driver choose between preset drive modes, suitable for various types of terrain and weather conditions. The system then adjusts throttle response, shift points, and the electronic stability control according to each mode. Related: 2018 GMC Sierra 1500 buying guide "The 2019 Sierra AT4 is designed for the customer who wants an elevated presence on the road and the capability to venture off life's beaten path," said Duncan Aldred, vice president of Global GMC. "It's also the beginning for the AT4 brand, which will be seen on every vehicle in our lineup in the next two years." Based on the new 2019 Chevrolet Silverado, the GMC Sierra (including the AT4 model) looks to stand out from its corporate cousin in terms luxury touches, along with some subtle exterior details. For the AT4, these visible differences include a body color grill surround and bumpers. Meanwhile, the inner grille, front fog-lights and faux fender vents feature a black-chrome finish. It's not flashy, which is probably exactly what GMC wanted for its upscale truck. The standard engine is a 5.3-liter V8, though buyers can choose an optional 3.0-liter turbo-diesel inline-six or 6.2-liter V8.
