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 recalling over 243,000 crossovers over possible seat belt defect

The summer of 2010's recall hit parade continues unabated today, with General Motors having just announced that it is asking 243,403 owners of its 2009-2010 Lambda crossovers to bring their three-row haulers in for inspection. The culprit? Second-row seat belts in select Buick Enclave, Chevrolet Traverse, GMC Acadia, and Saturn Outlook CUVs have "failed to perform properly in a crash."
According to GM, a second-row seat-side trim piece is to blame, as it can impede the upward rotation of the buckle after the seat is folded flat. As a result, if the buckle makes contact with the seat frame, cosmetic damage can occur, potentially requiring additional force to operate the buckle properly. So far, no great shakes, but in the process of applying that additional force, the occupant may push the buckle cover down to the strap, potentially revealing and depressing the red release button. As a result of this, the belt may not latch, or in certain cases, it may actually appear to be latched when, in fact, it isn't.

2021 GMC Canyon AT4 Road Test | The everyday tool

Bold take: The GMC Canyon is the most well-rounded midsize truck. Admittedly, “well-rounded” is a lukewarm compliment, but the Canyon does nearly everything well. It is not the flashiest, which is undeniably the Jeep Gladiator. Or the most comfortable, which is the Honda Ridgeline. But for those seeking a midsize truck that looks like a truck, drives like a truck and has a solid interior, the Canyon is the right formula. We would test the 2021 GMC Canyon AT4 for a week and find that itÂ’s pleasant, capable and sturdy off-road. We would haul a bookshelf in the bed, get dirty during a woodsy soft-road jaunt and pile up the miles running around town. In short, itÂ’s exactly what most need in a midsize truck.  The AT4 model is new for 2021, and it replaces the All-Terrain model, a move GMC is rolling out across its lineup. The AT4 adds an off-road-tuned suspension with hill-descent control, beefy 31-inch Goodyear Wrangler DuraTrac tires wrapped around 17-inch aluminum wheels, standard four-wheel drive with locking rear differential and a transfer case skid plate. The AT4 punches up the CanyonÂ’s appearance with red tow hooks, dark chrome elements and a bigger grille thatÂ’s similar to the SierraÂ’s. The Canyon Denali, which was also refreshed for ‘21, is showier, but the AT4 trim feels cooler with its understated off-road vibes. Considering this, we head out for an afternoon drive along a familiar route through DetroitÂ’s northern suburbs. The Canyon is a solid daily driver. The 3.6-liter V6 rated at 308 horsepower and 275 pound-feet of torque is widely used in General Motors vehicles. ItÂ’s powerful and actually sounds pretty good — even throaty — in GMCÂ’s midsize truck. Our passengers are surprised to be pulled back in their seats during hard acceleration, and the eight-speed automatic transmission is well-calibrated for the many jobs the Canyon is called upon to perform. This powertrain, standard in the AT4 and Denali trims, is a step up from the 2.5-liter inline-four and six-speed auto offered on the lower models. ItÂ’s worth it. The 2.8-liter Duramax diesel is an option on higher-spec Canyons, and its 369 lb-ft of torque is tantalizing. For everyday use, take the V6. Our tester with the gasoline V6 and four-wheel drive can tow as much as 7,000 pounds, has a maximum payload of 1,609 pounds and has respectable fuel economy of 17 mpg in the city and 24 mpg on the highway.
