2022 GMC Sierra Super Cruise First Drive | Now with trailering and automatic lane-changing

Although the updated late-model year 2022 GMC Sierra is still a little ways off (In fact, it hasn't even been revealed), we've had an opportunity to try one of its headlining features: Super Cruise. But it's not quite the Super Cruise you know from the current Cadillac line. The new Sierra will be getting a newer version with two features: the ability to execute lane changes and passes automatically, and the ability to operate with a trailer. We tried the system at GM's proving grounds in Milford, Mich., and our test vehicles were 2022 Sierra prototypes. Though the trucks themselves are early examples with features not finalized, GMC representatives said the Super Cruise system is pretty much finished. The system uses close and long-range radar sensors at the front and a new set of radar sensors at the back, plus the truck's various cameras. It also utilizes the mapping data that GM has accumulated for the system to ensure it operates on approved roads and has detailed information about where the car is. Now, the first new feature enabled by the updated Super Cruise is the automatic lane-change system. The current system can change lanes on its own, but it must be prompted by a press of the turn signal. That feature remains intact, but now, if you approach a slower vehicle on a multi-lane highway, Super Cruise can check the lane next to you to see if it's safe to merge, change lanes, and then return to the original lane once the slow-moving vehicle has been passed. This is where those rear radar sensors come in. We tried it three times on GM's big banked oval course, and it did it impressively smoothly. It was able to make the decision proactively, too, making the decision to change a good distance before we were on top of the slow moving car. Oh, and of course, because this is Super Cruise, it all happened without us having to touch the wheel. Our automatic lane change test was followed by trying Super Cruise with a trailer. Now, it's important to note that the automatic lane-changing functionality won't work with a trailer. This is because that function depends on a set of radar systems at the back of the truck that are blocked by a trailer. Apart from that, the rest of Super Cruise's functions still work just fine. To make this possible (and safe), the system is able to estimate the weight of the trailer and adjust following distance accordingly, allowing it to safely slow down as needed.

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.

GMC offers more 2024 Hummer EV SUV details, photos

GMC has shared more details about its 2024 Hummer EV SUV after its debut during the NCAA Final Four tournament. The SUV which follows the Hummer EV pickup, is smaller, more maneuverable and has a few features the truck doesn’t. GM says itÂ’s meant to strike a balance between off-road capability and on-road driving. GM also says Edition 1 reservations are already sold out. Compared to the truck, the Hummer SUV has a wheelbase about 9 inches shorter. With four-wheel steering, its turning circle is just 35.4 feet, which GM emphasizes is tighter than that of the Ford Mustang Mach-E (38.1 feet). ItÂ’s also less than the Hummer pickupÂ’s 37.1-foot turning circle. The SUV, which, at 196.8 inches long, is 20 inches shorter than the truck overall. It also features a much shorter rear overhang, at 35.5 inches. While thatÂ’s all helpful maneuvering through city traffic or suburban parking lots, it also provides advantages off-road. It has an approach angle of 49.6 degrees, a 49.0-degree departure angle and a 34.4-degree breakover angle. Suspension travel is 13 inches front and rear, with 16 inches of maximum ground clearance thanks to its Extract Mode that temporarily raises the vehicle to get out of tricky terrain. It can ford water 32 inches deep. It also features the same CrabWalk mode as the pickup. Available Ultravision provides 17 cameras, including underbody views to help navigate the trail. The Hummer SUV benefits from an enclosed cargo area behind the second row of seats. It still features the Infinity Roof with removable panels above the two seating rows to essentially turn the SUV into a convertible. At the rear is a swing-out tailgate that opens wider than the width of the vehicle. A spare tire rides on the tailgate as well. With the rear seats folded, cargo volume peaks at 81.8 cubic feet.  Additional hidden storage space is found below the recycled rubber floor mat, which features a design inspired by the moonÂ’s Sea of Tranquility (that's where Apollo 11 landed). As for technology, the Hummer SUV gets a 13.4-inch infotainment screen, plus a 12.3-inch instrument display in front of the driver. Fourteen cameras come standard, and the aforementioned Ultravision provides a total of 17 cameras, including a surround view. The MyGMC mobile app offers satellite rendered trail maps that can also help manage energy consumption off-road and make sure you have enough juice to make it to a charger when finished.
